Technology Reduces Production Costs of Lithium-ion Cells
Posted in Batteries, Electronics & Computers, Energy Efficiency, Energy, Transportation, News, GDM on Monday, 17 October 2011
A development by engineers of Germany's Karlsruhe Institute of Technology (KIT) is inspired by nature. To fill the porous electrodes of lithium-ion batteries more rapidly with liquid electrolyte, they use a physicochemical effect that also provides water transport in trees. The new process increases the throughput of battery production and reduces investment costs.
