While solid-state batteries are usually cited along with the 500 Wh/kg mark, the record 720 Wh/kg energy density of the new battery has been achieved with several technological breakthroughs.

"The all-solid-state lithium battery released uses a high-gram capacity, long-cycle lithium-rich manganese-based material for the positive electrode," tips Tailan, and adds that "in order to solve the solid-solid interface impedance problem... it is also equipped with Tailan New Energy’s unique high-performance oxide composite solid-state electrolyte."

Just as Elon Musk predicted, adding manganese is turning a very promising avenue for developing of high-performance EV batteries. CATL's M3P phosphate cells with manganese, for instance, offer 15% higher energy density than the LFP cells that Tesla uses in the Model 3 Highland.
