Leclanché’s aqueous  process reduces cobalt usage in NMCA cells, eliminates toxic solvent


Swiss battery maker Leclanché says it has found a way to reduce the cobalt content in nickel-cobalt-manganese-aluminum oxide (NMCA) cathodes from 20% to 5%, by using in a new environmentally friendly water-based process. The company’s G/NMCA cell has a nickel content of around 90%, which it says increases energy density and enables the reduction in… Read more »

Porsche fine-tunes Taycan EV braking for better recuperation without reduced comfort


A new article from Porsche highlights a technical challenge in chassis development for EVs: blending, which is when regenerative and hydraulic braking are combined. “The driver must not feel the transition between the systems,” says Martin Reichenecker, Senior Manager of Chassis Testing at Porsche Engineering. Guaranteeing a smooth transition places great demands on the technology,… Read more »
