Samsung plans to launch its commercial solid-state batteries in 2027, aiming to compete directly with Toyota and CATL by integrating breakthrough manufacturing techniques designed to significantly reduce costs, the South Korean tech conglomerate said.
The company has adopted a dry electrode production method similar to the one Tesla has promoted for its 4680 batteries. This method eliminates the need for energy-intensive solvent-based coating and drying processes, potentially halving production costs, a critical barrier to scaling solid-state battery technology for electric vehicles.
Samsung said it has achieved high energy density levels—up to 500 Wh/kg—for its solid-state cells, offering fast charging times of nine minutes and a range of 600 miles, all within the footprint of current EV battery packs.
The company is banking on two innovative processes to slash costs. The first is roll pressing, which avoids the complex Warm Istactic Press sealing and underwater high-pressure fusion commonly used in solid-state production. The second is a proprietary fiberization technique using a Teflon-based binder that enhances structural integrity and conductivity by forming a uniform separation layer between electrodes and electrolytes.
Samsung’s move comes as industry giants Toyota and CATL also target 2027 for mass production of solid-state batteries. CATL, initially skeptical about commercial readiness before 2030, has now accelerated its timeline in light of rapid technological progress.
