DETROIT – A breakthrough battery project started by General Motors in 2015 will produce a working power pack by the end of the decade, according to Kushal Narayanaswamy, the automaker’s director of advanced battery cell engineering.

The innovation is a lithium manganese-rich, or LMR, pack. Collaboration with LG Energy Solution has brought the promising technology over significant hurdles, including short lifespans and voltage decay. Now the team plans to unlock benefits headlined by low cost and “impressive range,” per Narayanaswamy.

The success is thanks to a mix of dopants, coatings, and particle engineering, according to the expert.

The LMR combo will form the cathode, one of two electrodes in a battery cell . Ions move between them through an electrolyte. Experts for m
