Ford is making significant strides in electric vehicle (EV) technology, with its top EV engineer announcing the active development of a potentially “game-changing” battery chemistry. This breakthrough, focusing on a novel lithium manganese rich (LMR) cell, promises to deliver both lower costs and extended ranges for Ford’s future EVs by the end of the decade. Charles Poon, the director of electrified propulsion engineering at Ford, revealed that the LMR cell chemistry is being developed at Ford’s Ion Park battery research and development center in Romulus, Michigan.
The development is not just theoretical; Ford is already producing second-generation LMR cells on a pilot line in Michigan, indicating a serious commitment to scaling this technology. This move signals Ford’s intent to not only compete but potentially lead in the rapidly evolving EV market.

According to Poon’s LinkedIn post, LMR chemistry offers several key advantages over traditional nickel-based batteries. These include enhanced safety and stability, crucial for consumer confidence and regulatory compliance. Furthermore, LMR batteries boast higher energy density, which translates directly to longer driving ranges, a primary concern for potential EV buyers. Perhaps most importantly, Ford anticipates “unprecedented” cost reductions with LMR, aiming for “true cost parity” with gasoline-powered vehicles. Achieving this would be a monumental step in making EVs accessible to a broader market.
However, the path to commercializing LMR batteries is not without its hurdles. Lithium-rich manganese-based cathode materials, while theoretically promising, have historically suffered from issues like voltage attenuation (loss of voltage over time), severe capacity loss (reduced driving range), and thermal stability degradation (potential safety risks at high temperatures). These challenges have prevented LMR from being widely adopted despite its discovery three decades ago.
| Advantages | Challenges |
|---|---|
| Improved Safety and Stability | Voltage Attenuation (Voltage Loss Over Time) |
| Higher Energy Density (Longer Driving Range) | Severe Capacity Loss (Reduced Driving Range) |
| Potential for Unprecedented Cost Reduction | Thermal Stability Degradation (Safety Concerns) |
| Elimination of Expensive/Dirty Materials (Nickel, Cobalt) | Commercialization Difficulties Despite Long History |

Ford’s pursuit of LMR battery technology is just one piece of its comprehensive EV strategy. Currently, Ford employs lithium-iron-phosphate (LFP) batteries in the base version of the Mustang Mach-E and nickel-manganese-cobalt (NMC) batteries in other models like the E-Transit and F-150 Lightning. The introduction of LMR represents the next step in Ford’s battery evolution, aiming to improve upon existing technologies.
Looking ahead, Ford has several new EV models in the pipeline, including a compact SUV and truck developed under its “skunkworks” affordable EV project, as well as the next generation of its electric truck, codenamed T3. Furthermore, Ford is exploring extended-range electric vehicle (EREV) versions of its SUVs, crossovers, and Super Duty pickup. These novel battery chemistries, like LMR, are not limited to specific vehicle types and can potentially be used in hybrids, PHEVs, EREVs, and BEVs, depending on the most economically viable application. The Ford EV battery strategy is clearly multifaceted.
