[SMM Lithium Battery Electrolyte Market Weekly Review: Electrolyte Prices Remained Stable This Week (2026.6.1-6.4)] From June 1 to June 4, 2026, electrolyte prices remained stable. Against the backdrop of poor cost pass-through in the earlier period, even though upstream raw material costs edged down, electrolyte prices are expected to remain stable in the short term.

Enchem America, the U.S. subsidiary of secondary battery electrolyte company Enchem, has agreed to merge with The GrowHub, a Singapore-based blockchain technology company listed on Nasdaq. The GrowHub said in a filing with the U.S. Securities and Exchange Commission (SEC) on June 1 local time that it had signed a binding agreement related to a business combination with Enchem America. The transaction is structured as a reverse merger. When a foreign company acquires a company listed on the U.S. stock market, the acquired U.S.-listed entity remains as the surviving company after the merger.

Under that agreement, Jiujiang Tinci was to supply electrolyte products to the ChuNeng New Energy enterprise system, with an estimated total supply volume of no less than 550,000 tons. This supplemental agreement increases the estimated total supply of electrolyte during the agreement period to no less than 1,010,000 tons. The actual procurement quantity is subject to subsequent purchase orders between the two parties.

Around May 23, 2026, import and export data for cobalt and lithium battery industry chain-related products in April were released in a concentrated manner. Data showed that China's spodumene imports in April reached 758,000 mt in physical content, down 9.5% MoM and up 21.7% YoY. Lithium carbonate imports, China imported 32,650 mt of lithium carbonate in April, up 9% MoM and up 15% YoY.......SMM compiled the import and export data for battery materials, as detailed below: Upstream Lithium Concentrates In April 2026, China's spodumene imports reached 758,000 mt in physical content, down 9.5% MoM and up 21.7% YoY, equivalent to approximately 63,000 mt of LCE. Customs data showed that April spodumene imports pulled back MoM from March, reaching 758,000 mt in physical content. By source country, Australian ore port arrivals returned to a relatively normal level, with over 350,000 mt arriving this month, up 38.9% MoM; Zimbabwe's earlier shipments arrived at port this month at 102,000 mt, down 9.2% MoM; South Africa and Nigeria saw some contraction in monthly port arrivals, while ore from Mali had almost no notable port arrivals this month due to shipping schedule impacts. Notably, spodumene powder sold by Brazil in early 2026 arrived at port this month, driving a significant increase in port arrivals from this country. Additionally, after SMM screening, the month's incoming ore was equivalent to 63,000 mt of LCE. Among the incoming ore, lithium concentrates accounted for 67%, edging down MoM, mainly because apart from Australia , ore from other source countries contained some relatively low-grade ore. Source: China Customs, compiled by SMM Spodumene concentrates (CIF China) spot pricing, according to SMM spot pricing, spodumene concentrates (CIF China) spot prices fluctuated upward in April. As of April 30, spodumene concentrates (CIF China) spot prices rose to $2,540/mt, up $221/mt from the month-end price of $2,313/mt in March, a gain of 9.81%. According to SMM, lithium carbonate prices continued to rise in April, and spodumene concentrates prices rose in tandem with salt prices, with gains exceeding those of lithium carbonate itself, causing non-integrated enterprises that purchase externally spodumene concentrates to suffer losses, with spot profitability remaining in deficit. In April, spot circulation of lepidolite concentrates relatively eased. Meanwhile, as lithium carbonate prices rose, processing fees for non-integrated enterprises also increased accordingly, preserving a certain profit margin for their processing operations and enabling these enterprises to achieve spot profitability. However, recently, spodumene concentrates prices adjusted in tandem with lithium carbonate price fluctuations, and the price center shifted downward. According to SMM's latest findings, disrupted by rumors of production resumptions at Jiangxi mines this week, lithium carbonate futures and spot prices declined, further dragging down the overall price center. Currently, lithium mines showed a weak willingness to make shipments, and transactions were mostly concentrated between traders and buyers. Port lithium ore inventory continued to decline. Going forward, attention should still be paid to the potential tight lithium ore supply triggered by high operating rates in the lithium chemicals industry. Lithium ore prices were expected to continue to hold up well. Lithium Carbonate According to customs data, China imported 32,650 mt of lithium carbonate in April, up 9% MoM and up 15% YoY. Of this, 21,000 mt was imported from Chile (65% of total imports), 9,555 mt from Argentina (29%), and 1,100 mt from Indonesia (3%). From January to April, China's cumulative lithium carbonate imports reached 116,000 mt, up 47% YoY cumulatively. In April, China exported 370 mt of lithium carbonate, down 17% MoM and down 50% YoY. From January to April, China's cumulative lithium carbonate exports totaled 1,886 mt, up 7% YoY cumulatively. In April, China imported 17,942 mt of lithium sulfate, up 9% MoM and up 296% YoY. From January to April, China's cumulative lithium sulfate imports reached 58,900 mt, up 121% YoY cumulatively. According to SMM spot quotes, spot lithium carbonate prices generally trended upward in April. As of April 30, the spot lithium carbonate price rose to 177,000 yuan/mt, up 14,000 yuan/mt from 163,000 yuan/mt on March 31, a gain of 8.59%. According to SMM analysis, China's lithium carbonate prices followed a "V-shaped" trend in April, first declining then rising, with the monthly average price up 6% MoM. In the first ten days, geopolitical disruptions in the Middle East intensified global risk-averse sentiment, causing non-ferrous metals and lithium carbonate prices to fluctuate downward. In the mid-to-late period, driven by Zimbabwe's export ban, Jiangxi mine license renewals, and rising costs, prices began to rebound and fluctuate upward, with the price center shifting notably higher by month-end. Upstream and downstream purchasing remained stagnant, with the psychological price spread widening week by week. Upstream producers held prices firm and held back from selling, maintaining high offer prices, while downstream buyers made just-in-time procurement only, with psychological price levels concentrated at 155,000-175,000 yuan/mt, restocking on dips only when prices fell rapidly. In April, spot battery-grade lithium carbonate prices dropped to around 155,500 yuan/mt in the first ten days, then rallied all the way to 177,000 yuan/mt by month-end. As of May 29, domestic spot battery-grade lithium carbonate was quoted at 174,000-181,000 yuan/mt, with an average price of 177,500 yuan/mt. Lithium Hydroxide According to customs data, in April 2026, China imported 6,689 mt of lithium hydroxide, up 9% MoM and up four times YoY. Of this, 2,252 mt were imported from South Korea, accounting for 34% of total imports; 1,706 mt came from Indonesia, accounting for approximately 25% of imports; and the remaining 40% came from Australia and Chile. In April, China exported 5,535 mt of lithium hydroxide, up 76% MoM and up 31% YoY, of which 3,915 mt were exported to South Korea and 864 mt to Japan. Continued sluggish ternary cathode material output outside China limited the absorption capacity for lithium hydroxide in markets outside China, resulting in a slight surplus in markets outside China, which in turn widened the price spread between domestic and overseas markets. Meanwhile, as suppliers outside China had previously signed long-term supply agreements with domestic traders, they were able to continuously dump lithium hydroxide into the Chinese market. Under the combined effect of these factors, the trade pattern of lithium hydroxide continued to reverse (shifting from net exports to net imports). Source: China Customs, compiled by SMM Battery Materials LiPF6 According to China Customs data, in April 2026, China's cumulative LiPF6 exports totaled approximately 868 mt, down approximately 80.9% MoM, while cumulative imports were approximately 96 mt. Export side, China's LiPF6 exports in April 2026 were approximately 868 mt, down approximately 80.9% MoM from March and down approximately 33.2% YoY. Specifically, as the LiPF6 export VAT rebate policy was officially abolished starting April 1, 2026, enterprises rushed to export in advance in March, and electrolyte enterprises outside China built up certain inventory, leading to MoM declines in China's exports to multiple major destination countries in April. Exports to Poland were 337.5 mt (down approximately 80.4% MoM), South Korea 81.804 mt (down approximately 92.56% MoM), Czech Republic 150 mt (down approximately 67.43% MoM), and the US 101.908 mt (down approximately 61.7% MoM). Only exports to Japan increased — 191.37 mt (up approximately 50.77% MoM). Artificial Graphite In April 2026, China's artificial graphite imports were 757 mt, up 12.4% MoM and down 32.9% YoY. Average import price side, in April 2026, the average import price of artificial graphite in China was 75,941 yuan/mt, up 23.1% MoM and up 14.6% YoY. In April 2026, China's artificial graphite exports totaled 45,895 mt, up 22.3% MoM but down 21% YoY. In terms of average export price, in April 2026, the average export price of China's artificial graphite was 9,214 yuan/mt, down 6.6% MoM but up 0.26% YoY. Exports from the top five exporting provinces rose 21% MoM from the previous month, with two provinces seeing export volume increases of over 35% MoM, and another province recording a 20% MoM increase. Import market, orders from downstream power battery enterprises in China gradually recovered in April. Combined with the phased tightness in spot capacity of leading anode enterprises, restocking demand was released, boosting artificial graphite imports to rebound from weakness on a MoM basis. However, import volumes remained down YoY, primarily because China's anode industry had ample overall capacity with supply still in surplus, domestic self-sufficiency continued to strengthen, and the industry's reliance on imported raw materials and finished products steadily declined. Flake Graphite In April 2026, China's flake graphite imports totaled 3,178 mt, down 19% MoM and down 45% YoY. Data source: China Customs, SMM In April 2026, China's flake graphite exports totaled 4,093 mt, down 50% MoM and down 54% YoY. Export market, the flake graphite export tax rebate policy was officially canceled this month, directly squeezing profit margins for foreign trade enterprises and significantly dampening overall export willingness. Meanwhile, the approval pace for flake graphite export licenses slowed down, hindering foreign trade shipments processes. Coupled with weak ex-China end-use demand, multiple bearish factors combined to directly drive a sharp decline in industry export volumes. The import market also continued to weaken. Goods originally intended for exports shifted to domestic sales circulation, with increasingly abundant local supply sources in China. Market enthusiasm for import procurement was insufficient, ultimately causing imports to decline in tandem this month. Phosphate Ore On May 20, 2026, according to customs data, China's phosphate ore imports totaled 207,000 mt in April 2026. April imports rose 13.5% from 182,000 mt in March. Total import value in April was $19.741 million, up 35.7% MoM from $14.552 million in March. The average unit price was $95.5/mt, up 19.6% from $79.9/mt in March. Import commentary: In May, Egypt's phosphate ore exports faced "policy tightening and weakening demand."On May 13, Egypt's Ministry of Petroleum and Mineral Resources announced that it would no longer sign any new phosphate ore export contracts. Previously, Egyptian Prime Minister Mustafa Madbouly stated clearly at a meeting on May 10 that the government was pushing for a transition from raw material exports to the manufacturing of high-value-added products such as phosphate fertiliser. Already signed long-term contracts would not be affected. This is expected to push up import prices and may affect imports. Cobalt Cobalt Hydrometallurgy Intermediate Products In April 2026, China's cobalt hydrometallurgy intermediate products imports were approximately 1,247 mt in physical content, down 26% MoM and down 98% YoY. Among them, imports from the DRC were approximately 945 mt in physical content, down 43% MoM and down 98% YoY. In April 2026, the average import price of China's cobalt hydrometallurgy intermediate products was $17,187/mt in physical content, up 2.63% MoM. It was learned that most miners had completed the Q4 2025 quota approvals, but the Q1 2026 quota approvals slowed down again due to sampling, detection and other procedural issues. In addition, transportation capacity in the DRC was tight. Fleets, driven by economic considerations, prioritised the transport of oil products and chemicals that were in production shortage, followed by other metals with shorter turnover cycles, and cobalt among non-ferrous metals came last, meaning cobalt faced significant transportation capacity issues. Constrained by the above factors, miners mainly focused on building in-transit inventory and had not yet arranged concentrated vessel bookings, and the arrival of large batches of intermediate products at ports may continue to be delayed. Unwrought Cobalt In April 2026, China's unwrought cobalt imports were approximately 1,334 mt, up 39% MoM and up 59% YoY. In April, refined cobalt imports mainly came from Indonesia, Russia, and Madagascar, with imports of 462 mt, 457 mt, and 182 mt respectively. The main reason for the increase this month was that domestic smelters lacked intermediate product raw materials and imported cobalt slabs and cobalt briquettes for re-dissolution to ensure normal production. In terms of average import prices, the average import price of China's unwrought cobalt in April 2026 was $52,724/mt, up 4.72% MoM. Cumulative imports from January to April 2026 totalled 5,916 mt, up 153% YoY cumulatively. Export side, China's unwrought cobalt exports in April 2026 were approximately 218 mt, down 47% MoM and down 95% YoY. By country, China's exports to the US dropped significantly, with April exports to the US at 35 mt, down 87.5% MoM. The main reason was that demand for alloy-grade refined cobalt in the US pulled back in April, and ex-China branded refined cobalt was already sufficient to meet regional demand, with some refined cobalt traders redirecting their destinations from the US back to China. Average export price, the average export price of China's unwrought cobalt in April 2026 was $54,590/mt, up 5.80% MoM. Cumulative exports from January to April 2026 totaled 1,792 mt, down 76% YoY.
