BYD says its solid-state electric vehicle battery technology is almost ready for real-world use. The Chinese automaker is among several manufacturers racing to commercialize solid-state batteries, which promise greater range, faster charging and improved safety over today's lithium-ion cells. Any movement toward production from a company of BYD's scale is being closely watched across the auto industry, as a breakthrough could reshape competition in the fast-growing electric vehicle market.
