Here comes the solid-state battery! The lithium giant says it can be mass-produced and loaded at any time! On December 8, a source revealed: "as far as I know, the formulation and preparation process of BYD's all-solid-state lithium metal laminated battery have indeed been developed and are being continuously optimized. The project also won the internal first prize. " The news further pointed out, "it should not be mass production in the short term. BYD does not need to fight for eyeballs like other car companies, but pursues technologies that can be popularized on a large scale at low cost and products that bring tangible benefits to consumers."
