This is only incomplete statistics of solid-state battery news since October.
Byd has exposed a very specific solid-state battery plan:
From the perspective of technical route selection, the Fodi battery is very likely to choose the technical route of high nickel ternary (single crystal)+ silicon base negative electrode (low expansion)+ sulfide electrolyte (composite halide).
The capacity of Ferdi solid state battery can be more than 60Ah, the mass specific energy density reaches 400Wh/Kg, the volume specific energy density reaches 800Wh/L, the needle or hot box does not fire and does not explode, and the battery system and the vehicle efficient integration technology under the thermal management, safety, fast charge and other performance requirements, the battery pack energy density exceeds 280Wh/Kg.
In terms of cost control, the reduction of sulfide (or sulfide + halide complex) solid electrolyte, which occupies the absolute proportion of cost, is planned to reduce the cost of LiS by 1500%-2000% in 2027 compared with the cost reduction effect in 2024, and reduce the cost again by 30%-50% compared with 2027 through the improvement and optimization of the synthesis process in 2030. 2033 will continue to reduce costs by about 20%-30% through scale efficiency.
In terms of the cost of solid-state batteries, the overall material BOM cost is planned to be reduced by 2000%-3000% in 2027 after the cost reduction effect of solid-state electrolytes, and then the manufacturing cost is reduced by 30%-50% by improving the product yield + scale effect + process optimization, so as to be highly competitive in price.
In terms of mass production schedule, consistent with the national policy and most enterprises, small batch production in 2027, equipped with BYD high-end models as demonstration projects, the scale is only about 1000 units; In 2030, for the market promotion period, it is expected that 40,000 vehicles will be installed with all-solid-state batteries, and begin to explore the mainstream price segment of the model; In 2033, it is expected that there will be 120,000 large-scale installed vehicles, and the market share of all-solid-state batteries will gradually increase.
infor vertical sand mill
Through the fine grinding process, the ionic conductivity and electrochemical performance of the solid electrolyte can be optimized, which is of great significance for the development of solid-state batteries.
infor vertical sand mill has unique performance advantages in solid electrolyte ultrafine grinding. First, there is no screen structure, and grinding beads as low as 0.03mm can be used to challenge finer grinding fineness; Second, the unique separation structure, small particles are preferentially discharged, large particles continue to grind, narrow particle size distribution; In addition, the vertical sand mill does not need to be coarse grinding, no need to replace zirconium beads, and comprehensively reduces the construction and production costs of the production line.
Welcome the majority of solid-state battery industry practitioners to visit our company, to discuss the problem of solid-state electrolyte grinding and production line applications.
