“A central, technical problem is to bring the fixed ion conductor in the battery cells into a stable connection with the electrodes. The core of the storage technology is the solid ion conductor, which replaces conventional liquid electrolytes. This liquid predecessor technology has already been produced on an industrial scale.” “The predecessor technology of the solid-state battery – still on a liquid basis – has already completed more than 50,000 charging cycles in practical use in the USA in a battery storage system for buffering the power grid. “As a result of this and the extreme service life, the environmental balance can be improved by more than half compared to conventional lithium-ion batteries,” Lützenrath explained. The battery technology does not require any critical raw materials such as cobalt or gold. “By using our protected electrolyte made of a solid ion conductor, the internal resistance and capacity will remain virtually constant over the service life. “After that, it doesn't grow anymore,” he explained. This growth of the top layer consumes capacity and increases the internal resistance, and the performance of the battery decreases,” he told pv magazine.īy contrast, a very thin top layer in the pure solid-state batteries is formed during the first charge, said Lützenrath. This grows over time and with each use, even faster the more intensively the battery is used. “Conventional lithium-ion batteries age because a covering layer is formed on their anodes through charging and discharging. A production area of 20,000 m2 will be built in order to manufacture 7.2 million battery cells per year.”ĬOO Thomas Lützenrath said the batteries will have several competitive advantages compared to conventional lithium-ion storage. In this first stage, SCB AG employs 181 people. For this, CHF 246 million investment volume in the machinery is planned.

“In the first production phase of 1.2 GWH, SCB AG is planning sales of CHF 318 million ($340 million). “With production scaling from 1.2 GWh to 7.6 GWH, SCB AG will serve both the Swiss domestic and international markets with sustainable battery storage from 2024,” the company said.

Swiss startup Swiss Clean Battery (SCB) AG said this week that it will build a gigafactory to produce pure solid-state batteries at its headquarters in Teufen, Switzerland.
