General Motors and LG Energy Solution They have recently announced their intention that will market LMR battery cells for future GM electrical models, which represents a new technological advance in batteries. This is based on the collaboration between both companies to develop prismatic battery cell technology and its related chemical components.
GM aspires to implement LMR battery cells in electric vehicles. Likewise, Ultium Cells, a joint company of GM and LG Energy Solution, plans to start the commercial production of LMR prismatic cells in the United States by 2028, and Preproduction is expected to begin at an LG Energy solution plant at the end of 2027.
LMR battery cells release an energy density
The final production design of these LMR battery cells will be validated at the GM Development Center in Warren, Michigan, whose opening is scheduled for the beginning of that year, as well as at the LG Energy Solution facilities. The battery cathodes require materials such as cobalt, nickel and manganese, the cobalt being the most expensive. However, LMR battery cells use a greater proportion of manganese, more affordable, while offering greater capacity and energy density.
The engineers of this project have developed a new LMR prismatic battery cell that releases An energy density a 33 % higher compared to cells based on iron and lithium phosphate (LFP) of betterat a comparable cost. By integrating LMR batteries technology and the manufacturing and efficiency advantages of prismatic cell space, GM seeks to offer More than 640 kilometers of autonomy in one of its electric truck models.
The American brand began investigating lithium -rich ion batteries cells in manganese in 2015, accelerating the development of this technology through the development of LMR prototypes in its facilities. In collaboration with partners, GM designed advanced cathodic materials, electrolytes, additives, form factors and cell assembly processes to overcome the challenges inherited from LMR in terms of performance and durability.
LG Energy Solution has the greatest intellectual property portfolio in LMR technology worldwide, with More than 200 patents in this field. His experience is based on extensive research, and his first patent on LMR’s chemistry dates from 2010. LMR battery technology is integrated into the battery supply chain and GM cell manufacturing processes.
The question we all ask ourselves is whether the LMR battery cell technology will gradually reach the two -wheeled sector. Telling the range of autonomy estimated for a GM electric truck, so how many km could we travel to the controls of a plug -in mount? We will know soon.
