This week (February 27, 2026–March 5), more players entered the solid-state battery industry, with various parties “riding” the hype: Sunstone Development and TONZE stated that their sulphide projects were still in the early R&D stage; QingTao’s Wuhai 2 billion yuan project released its EIA public notice, and a 3.5 GWh production line in Taizhou commenced operations; Suzuki acquired Kanadevia’s solid-state battery business

Recently, China Construction Decheng announced the bidding results for energy storage projects in Denmark and Spain. The total capacity of these energy storage systems reached 1.12 GW/2.4 GWh, and four suppliers—CRRC Zhuzhou Institute, Envision Energy, Sungrow, and Great Power Energy—successfully won the bids, with the winning prices ranging between 0.8362 and 1.0431 yuan/Wh. The energy storage project covers eight projects in Denmark and Spain, with a procurement scale of 1,116.5 MW/2,427.72 MWh. The total investment amounted to 2.5 billion yuan, which translates to a unit price of approximately 1.0297 yuan/Wh. It is worth mentioning that in October of last year, China Construction Decheng signed cooperation agreements with Denmark's DRSOLAR and NORLA for a 2.5 GWh energy storage project. The project will adopt an LFP battery system and an intelligent energy management system.

[SMM Analysis: Key Anchor in Great Power Rivalry: The U.S. "Project Vault" and the Changing Resource Landscape in Latin America] Amid the current accelerated reshaping of the global resource competition landscape, China's copper concentrate import pattern is undergoing a profound structural transformation. The latest trade data from 2025 clearly outlines this trend: China is significantly enhancing its capacity to acquire copper concentrate resources from neighboring countries.

[SMM Analysis: Key Anchor in Great Power Rivalry: The U.S. "Project Vault" and the Changing Resource Landscape in Latin America] While the second phase of Chinese company's Mirador copper mine in Ecuador remains mired in a 'completed but awaiting approval' deadlock, 10,000 kilometers away in Washington, the President, alongside the Export-Import Bank of the United States, is announcing a historic supply chain security initiative named 'Project Vault.'

[SMM Analysis: The "Key Anchor Point" in Great Power Rivalry: The US "Treasury Plan" and the Resource Reshuffle in Latin America] As the second phase of the Mirador copper mine project in Ecuador, developed by a Chinese enterprise, remains stuck in a "built but awaiting approval" deadlock, ten thousand kilometers away in Washington, the US Export-Import Bank, together with the President, is announcing a historic supply chain security initiative called the "Treasury Plan." In the pause and the start, a global covert battle over critical minerals such as copper, lithium, cobalt, and gallium is moving from behind the scenes to the forefront.

Great Power Energy (300438.SZ) announced that the company plans to invest in the construction of a 587Ah battery and 120Ah battery production project in Yicheng District, Zhumadian City, with a total investment of 1.2 billion yuan.

Although the China-U.S. dialogue in London sent a signal of easing tensions in rare earth magnetic material trade, the current situation in the industry is still marked by a contraction in short-term orders and a strong wait-and-see sentiment in the market. In the long run, Chinese magnetic material enterprises are leveraging this momentum to accelerate their transformation towards high-end and green development, with technological breakthroughs and supply chain restructuring becoming key bargaining chips for restarting cooperation in the future.

[Great Power Energy and Mingtai Al. Sign Cooperation Agreement on Solid-State Batteries, etc.] Today, Henan Mingtai Al. Industrial Co., Ltd. (hereinafter referred to as "Mingtai Al.") announced in a statement that it had signed a "Strategic Cooperation Framework Agreement" with Guangzhou Great Power Energy & Technology Co., Ltd. (hereinafter referred to as "Great Power Energy"). Through friendly consultations, the two parties decided to establish a multi-level and all-round strategic partnership in the R&D, product supply, technology development, capacity layout, and other aspects of new-type batteries such as solid-state batteries and sodium-ion batteries. Meanwhile, they would also cooperate in aluminum recycling, leveraging their respective business functions and material collection capabilities to promote the recycling and application of secondary aluminum alloy in the field of new energy batteries. According to the agreement, Great Power Energy would give priority to Mingtai Al.'s products in solid-state battery or other battery projects. The two parties would jointly establish an information communication and resource-sharing mechanism, continuously strengthen technical exchanges and consulting services, and achieve business extension and expansion.

Mingtai AL.Industrial Co., Ltd. signed a strategic cooperation agreement with Great Power Energy to deeply deploy in cutting-edge fields such as solid-state batteries and sodium-ion batteries, providing full-chain material support for solid-state battery projects. The company's independently developed 8021 and 8079 alloy aluminum-plastic film aluminum foil products have gained industry recognition for their dual-core performance of "high barrier + high surface". Through hot rolling and rigorous cold rolling processes, these products simultaneously possess characteristics such as moisture resistance, airtightness, and light shielding, meeting the requirements of global mainstream certifications including national standards, American standards, and European standards, and can meet the needs of solid-state batteries for complex exterior shapes.

Recently, the China Society of Automotive Engineers (China-SAE) released the group standard "Determination Method for All-Solid-State Batteries", which clearly defines all-solid-state batteries for the first time, requiring that ion transport be achieved entirely through solid electrolytes, thus establishing a strict technical demarcation from hybrid solid-liquid electrolyte batteries. The standard was jointly drafted by the China Automotive Technology and Research Center New Energy Vehicle Inspection Center (Tianjin) Co., Ltd., leading a collaboration with over 50 organizations. The introduction of this standard effectively avoids speculative hype around the concept and provides more unified metrics for material development, process optimization, equipment adaptation, and other aspects.
