GM's Next-Gen Battery Is Inching Closer To Production
GM and LG Energy's lithium manganese-rich batteries to be produced in Tennessee, promising affordability and high energy density.
Key Takeaways
- GM and LG Energy will produce lithium manganese-rich (LMR) batteries in Tennessee.
- LMR batteries promise to be affordable and have a high energy density.
- The batteries will be used in electric trucks and full-size SUVs, including the Chevrolet Silverado EV.
- Production is expected to begin by 2028, with construction and facility upgrades starting later this year.
- The expansion will create an additional 500 jobs, bringing the plant’s total to around 1,700.
How Do LMR Batteries Work?
Traditional battery cathodes require nickel, manganese, and cobalt, with cobalt being the most expensive material. LMR batteries use a higher proportion of manganese, which is far more affordable.
This lowers the cost of LMR batteries, making electric full-size trucks and SUVs more competitive. GM officials have previously suggested that using LMR batteries on the Chevrolet Silverado EV could save at least $6,000.
What Are the Benefits of LMR Batteries?
LMR batteries are designed to offer energy density 33% greater than lithium iron phosphate (LFP) chemistry, but at a comparable cost.
This makes them an attractive option for electric vehicles, particularly in the full-size truck and SUV segment.
How Will GM Use LMR Batteries?
GM will adopt a multi-battery approach, using LMR batteries in affordable variants and high-nickel batteries in long-range versions.
This will allow the company to cater to a wide range of customers and offer more competitive pricing.
What Does This Mean for the Electric Vehicle Market?
The production of LMR batteries is a significant step forward for the electric vehicle market, particularly in the full-size truck and SUV segment.
With the cost of batteries being a major hurdle for many consumers, the introduction of more affordable options like LMR batteries could help increase adoption rates.
