The Volkswagen Group is determined to start production of solid-state batteries in 2025 and has announced promising results from tests with the new technology.
According to Automotive News Europe, tests conducted with a prototype developed by QuantumScape, a US-based company partnered with VW, exceeded industry benchmarks in recent tests.
During tests of VW’s PowerCo battery unit, the cell registered a 5% loss in storage after more than 1,000 charging cycles. This is equivalent to approximately half a million miles of driving.
The German automaker also recalled that industry targets for this development stage are 700 charging cycles and a maximum loss of 20% of capacity.
“These results are very encouraging,” emphasized Frank Blome, head of PowerCo. “The outcome of this development could be a battery cell that allows for long ranges on a single charge, and that can be charged quickly without degrading.”
Solid-state batteries are considered the next generation of batteries for electric vehicles. They offer a number of advantages over traditional lithium-ion batteries, including higher energy density, longer lifespan, and shorter charging times.
The results achieved by VW and QuantumScape are an important step in the development of solid-state batteries. If the tests are successful, this technology could revolutionize the electric vehicle market.
