SK On's Solid-State Batteries Could Enable 8-Hour Robot Operation Despite Cost Increase

SK On has announced that solid-state batteries can allow industrial robots to operate for up to 8 hours, addressing a significant limitation of current lithium-ion batteries, which typically provide only 1 to 2 hours of runtime. This advancement could reduce downtime in 24-hour production lines, where frequent battery changes are necessary.
However, the cost implications are substantial. Currently, lithium-ion batteries account for less than 2% of the total cost of industrial robots, but switching to solid-state batteries could increase this to approximately 8%, resulting in a fourfold rise in overall costs. For instance, Tesla's Optimus robot has a battery cost of about $300, which is only 0.5% of its total hardware cost.
SK On has developed a total cost of ownership (TCO) model that factors in the costs of spare batteries, charging downtime, and additional backup machines, suggesting that solid-state batteries may be more economical in the long run for continuous operation scenarios. The company has completed a solid-state battery pilot plant in Daejeon, South Korea, and plans to commercialize two battery technologies by 2028 and 2029, respectively. No further timeline was disclosed at the time of publication.
