SMM News, November 11: Key Points: In November 2025, BYD's FinDreams Battery updated the official technical information graphic for consumer batteries on its website, listing solid-state electrolytes under electrolytes as part of chemical innovations. Other materials, such as high-energy-density ternary cathode materials, high-energy-density silicon-based anodes, and ultra-thin, high-viscosity separators, were also integrated with solid-state electrolytes to form a closed loop for solid-state batteries. BYD is one of the six enterprises involved in the R&D, advancement, and commercial application of solid-state battery products and technologies supported by national subsidies. Its solid-state battery business is being advanced by its subsidiary, FinDreams Battery. Due to challenges in producing large-format solid-state battery cells, inconsistent batch stability, and downstream industries' sensitivity to the cost of solid-state batteries, the initial application areas for solid-state batteries will start with small batteries, low energy storage requirements, and cost-insensitive fields such as 3C consumer electronics, the low-altitude economy, and humanoid robots. FinDreams Battery's applications will also begin in these three areas. Its website updated the official technical information graphic for consumer batteries, listing solid-state electrolytes under electrolytes as part of chemical innovations. Other materials, such as high-energy-density ternary cathode materials, high-energy-density silicon-based anodes, and ultra-thin, high-viscosity separators, were also integrated with solid-state electrolytes to form a closed loop for solid-state batteries. BYD's overall solid-state battery roadmap is as follows: - 2027: Small-scale installation in vehicles is planned. - 2030: Achieve cost parity between solid-state and liquid batteries and expand to 40,000 units. - 2033: Achieve installation in 120,000 units and increase market share. The Chongqing Bishan base is planned with a capacity of 100 GWh, with the first phase of 20 GWh expected to commence production in 2026. At the 2025 Second China All-Solid-State Battery Innovation and Development Summit, BYD's CTO Sun Huajun announced that the company had already produced a 60 Ah all-solid-state battery sample in 2024. Through "sulphide electrolyte process optimization + mass production adaptation of silicon-based anodes," the cost during the mid-2025 pilot phase had been reduced to 1,200 yuan/kWh, a 33% decrease from the 2023 sample cost (1,800 yuan/kWh). Cost reduction: The adoption of an "integrated solid-phase sintering process" replaced traditional step-by-step synthesis, increasing production efficiency by 25% and raising yield from 65% to 85%. The use of NCM811 high-nickel materials instead of cobalt-based materials in the cathode reduced material costs by 20%. With the addition of the 20 GWh pilot production line in Shenzhen commencing operation in 2026, the battery cell cost is indeed expected to be reduced to 500 yuan/kWh during the 2027 demonstration installation phase. According to SMM projections, all-solid-state battery shipments are expected to reach 13.5 GWh by 2028, while semi-solid-state battery shipments are forecast to reach 160 GWh. By 2030, global lithium-ion battery demand is estimated to be around 2,800 GWh, with the compound annual growth rates from 2024 to 2030 for lithium-ion battery demand in EVs, ESS, and consumer electronics at approximately 11%, 27%, and 10%, respectively. The global penetration rate of solid-state batteries is projected to be around 0.1% in 2025, and is expected to reach about 4% for all-solid-state batteries by 2030. By 2035, the global penetration rate of solid-state batteries may approach 10%. **Note:** For further details or inquiries regarding solid-state battery development, please contact: Phone: 021-20707860 (or WeChat: 13585549799) Contact: Chaoxing Yang.
