Sunwoda to make solid batteries cheaper
China DailyAn employees works on the production line of battery maker Sunwoda in Zaozhuang, Shandong province. "We are currently constructing a production line for such batteries and aim for mass production of the all-solid-state battery by 2026, with an expected capacity of 1 GWh," he said. All-solid-state batteries offer higher theoretical energy density and safety, and entail lower costs than lithium-ion batteries that currently dominate the electric vehicle sector. "While all-solid-state batteries offer a crucial solution balancing high energy density and safety, they are not the only solution," Xu said. He also said the cost of sulfide-based all-solid-state batteries remains high, with low market acceptance, and it is uncertain how much the cost can be reduced in the next 3-5 years.
