Commentary: GM’s ‘next-gen’ EV batteries show promise – but key hurdles remain

"Lithium manganese-rich (LMR) cathodes offer much higher energy density than current Nickel Cobalt Aluminium Oxide (NCA), Nickel Cobalt Manganese Oxide (NCM), and Lithium Iron Phosphate (LFP) batteries, while reducing reliance on expensive cobalt, making them a strong candidate for next-generation electric vehicles (EVs). However, their high-voltage operation triggers oxygen release, leading to structural degradation, electrolyte decomposition, voltage fade, and reduced energy/power density. These issues not only limit battery health but also raise safety concerns.

"While advances in material design are promising, wide adoption will also depend on intelligent battery sensing to monitor degradation in real time and ensure safe, stable operation. A 2028 rollout is possible in niche markets, but broader use requires further breakthroughs in stability and interfacial-related issues."
