Lithium Manganese Rich battery
Lithium Manganese Rich (LMR) batteries are a class of lithium-ion battery cathodes characterized by high specific capacity and energy density, leveraging manganese-rich structures to reduce cost and reliance on cobalt.
Key Developments (2026)
- LG Energy Solution Breakthrough: Significant progress announced in LG LMR Breakthrough: Cheaper, Longer-Range EV Batteries Surpassing LFP regarding commercial viability.
- Cost: Achieved production costs lower than LFP (Lithium Iron Phosphate) batteries.
- Performance: Surpassed LFP in energy density, enabling longer vehicle range.
- Implications: Positions LMR as a competitive alternative to both NMC (for cost/weight) and LFP (for range/cost balance).
