Kushal Narayanaswamy, GM director of advanced battery cell engineering, says the company’s LMR batteries can deliver 33 percent higher energy density than China’s best LFP cells, at comparable ...

Construction of a $3.5 billion GM/Samsung EV battery plant near South Bend, Indiana, is underway after initial delays and partnership changes. Alongside the battery plant, Amazon Web Services is ...

GM is targeting the new batteries and chemistry inside them — called lithium manganese-rich (LMR) prismatic battery cells — to be used in full-size electric vehicles such as its Chevrolet ...

GM has been researching battery cells with manganese-rich cathodes since 2015. By the end of 2024, it had tested hundreds of large-format prismatic cells, or the equivalent of 1.4 million miles of ...

A long time coming. GM has been researching manganese-rich lithium-ion battery cells since 2015, prototyping the technology at its Wallace Battery Cell Innovation Center in Warren, Michigan.

GM’s work to develop LMR prismatic battery cells began in 2015, but researchers were studying LMR technology long before that. Though they promised high range for a lower price, historically LMR ...

The new cells will be made by Ultium Cells, GM’s joint venture with LG Energy Solution. Through Ultium, the two companies have invested billions of dollars in battery manufacturing in the United ...

Ultium Cells, GM's and LG Energy Solution's joint venture, aims to begin pre-production of its LMR battery cells by late 2027. Commercial production is slated for 2028, when the battery will find ...

GM expects the LMR prismatic battery cells to have 33% higher energy density, providing addition miles of range, compared with the best-performing LFP cells, but at a comparable cost.
