GM has announced new EV battery technology it claims is both less expensive and lighter than current cells. The automaker is calling these so-called groundbreaking units LMR, short for lithium manganese-rich prismatic battery cells.
If the technology delivers as promised, it could help address two of the biggest obstacles facing electric vehicles: cost and weight. Whether GM can scale the batteries into real-world production at meaningful volume will determine how groundbreaking they truly are.
