Introduction
As the world moves faster toward electric vehicles (EVs), better battery technology is essential to make these cars go farther, cost less, and use materials that are easy to get. An emerging battery type that is receiving a lot of interest is the lithium manganese-rich (LMR) battery. These batteries have more manganese in their cathodes, which makes them cheaper and promising for the next generation of EV batteries. Because manganese is more common and less expensive than metals like cobalt and nickel, LMR batteries can help reduce costs while still providing good energy storage. This makes them a strong candidate for powering future electric cars, trucks, and SUVs with longer driving ranges and more affordable prices.
What is an LMR Battery?
In an LMR battery, trace amounts of nickel and cobalt are added to the cathode, which is mostly composed of lithium manganese oxide. Common batteries with higher cobalt and nickel content, such as NMC (Nickel Manganese Cobalt) or NCA (Nickel Cobalt Aluminum), differ from this. LMR batteries can store a lot of energy at a lower cost because manganese is readily available and inexpensive. Because of its unique layered structure, the battery can contain more lithium and function better for longer.
How is LMR Different from Other Battery Chemistries?
LMR batteries are different from other battery types mainly because they contain much more manganese. While regular NMC batteries have about 85% nickel, 10% manganese, and 5% cobalt, LMR batteries increase the manganese content to around 65%, with about 35% nickel and very little cobalt. This modification reduces the cost of LMR batteries while decreasing their dependence on scarce and expensive elements such as cobalt. In addition to having more manganese, LMR batteries can store more energy, with capacities over 250 mAh/g, which is about 33% higher than lithium iron phosphate (LFP) batteries while costing about the same. Another difference is their shape: LMR batteries usually come in prismatic, or box-like, cells instead of the pouch shapes common with high-nickel batteries. This prismatic design helps make battery packs simpler, lighter, and better suited for large electric vehicles like trucks and SUVs.

Technical Challenges Facing LMR Batteries
LMR batteries, despite their promising capabilities, must overcome numerous technical hurdles. One major issue is the oxygen release from the cathode during charging and discharging, which can damage the battery’s structure and reduce its safety and capacity. Another problem is voltage decay, where the battery loses usable power over time, making it less efficient. LMR batteries also have slower lithium-ion movement inside them, which limits how much power they can deliver and how quickly they can charge. Additionally, the battery’s capacity can fade after many charge cycles due to changes in its structure and the loss of manganese. When used with solid-state electrolytes, keeping a stable connection between the cathode and electrolyte is also difficult. Scientists are working to fix these problems by adding other elements (doping), applying special coatings to the battery materials, improving the crystal structure, and modifying the electrolyte to help make LMR batteries last longer and work better.
How Competitive is LMR Battery Technology?
- Cost Efficiency: LMR batteries have high manganese which is cheaper than cobalt and nickel, reducing the raw material and production cost for EV batteries.
- Higher Energy Density: These cells provide about 33% greater energy density when compared to LFP batteries, having a longer driving range, lighter battery at a similar cost.
- High Voltage Capability: Greater energy storage capacity per cell due to a wider voltage range (up to about 4.8V).
- Simplified Battery Design: Using bigger prismatic cells (rectangular format) with LMR improves packaging efficiency, particularly in trucks and SUVs, by reducing the number of battery pack components by 50%.
- Sustainability & Environmental Impact: Appealing to automakers who want to create sustainable supply chains for batteries. Less harmful to the environment because of the decreased effects of cobalt mining.
Major Players in LMR Technology
General Motors and LG Energy Solution, through their Ultium Cells joint venture, are leading the development of LMR batteries, with plans to begin high-volume commercial production by 2028. Ford has also announced initiatives to include LMR battery chemistries in their future electric vehicle models, aiming to achieve similar improvements in performance and cost. In addition, academic institutions and materials research groups around the world are actively working on improving LMR cathode materials by exploring techniques such as doping, nanostructuring, and innovative coatings to improve battery performance and get around current technical obstacles.
Recent Developments and Future Outlook
Advances in nanostructuring lithium manganese oxides (e.g., monoclinic layered LiMnO₂) and new synthesis methods have improved fast-charging capabilities and reduced voltage decay, marking significant progress toward commercial viability. Ultium Cells: By 2028, prismatic lithium manganese rich (LMR) cells will be produced domestically by a joint venture between a South Korean battery technology business and a large American automaker, aiming at EV trucks and SUVs with 400+ mile ranges. Future trends include integrating LMR cathodes with solid-state electrolytes and silicon-carbon anodes to achieve higher energy and safety benchmarks in all-solid-state batteries.
Why Is It the Right Time to Make an LMR Technology Investment?
