LG Energy Solution Sees Solid-State Battery Delay for EVs
LG Energy Solution has diagnosed that in order to fully apply solid-state batteries to electric vehicles, the technical barrier of mass-producing large-scale cells must be overcome.The forecast suggests that solid-state batteries are highly likely to be commercialized in small products such as smart
LG Energy Solution has revealed that mass-producing large-scale solid-state batteries for electric vehicles (EVs) is a significant challenge. The company predicts that these batteries will likely first be found in small products like smartphones before being employed in EVs. A recent interview by Lee Hyuk-jae, Executive Vice President of LG Energy Solution in North America, at the Lansing plant in Michigan, confirmed the technical hurdle of mass production.
Lee stated that solid-state batteries' high energy density, which offers increased energy in a smaller space, is promising for small form factors but poses difficulties for larger ones. Solid-state batteries, which replace the liquid electrolyte found in traditional lithium-ion batteries with a solid one, are dubbed 'dream batteries' due to their capacity to reduce fire risks and boost energy density.
However, their commercialization faces the challenge of mass-producing large cells with consistent quality. LG Energy Solution anticipates smartphones to see solid-state batteries approximately 10 years ahead of electric vehicles. The company is also exploring other initial applications, such as special gadgets like drones and high-performance electric vehicles.
Mercedes-Benz, BMW, and Stellantis are currently testing solid-state or semi-solid-state batteries in their test vehicles. LG Energy Solution's research and development of solid-state batteries continue, with a target commercialization date of 2029 for sulfide-based solid-state batteries. The company plans to broaden the application of solid-state batteries to electric ships and energy storage systems after progressing with high-performance premium electric vehicles.
LG Energy Solution has announced plans to establish a pilot production line for solid-state batteries employing a dry electrode process in the second half of the year. This dry electrode process, which eliminates solvents during electrode manufacturing, simplifies the production process and reduces costs, potentially increasing the mass producibility of solid-state batteries.
