Accelerated electrode drying could reduce battery production cost

A new EPIC project coordinated by Karlsruhe Institute of Technology (KIT) is aimed at accelerating the drying of electrodes for lithium-ion batteries, increasing the energy efficiency of this process and reducing production cost. KIT says innovative electrode drying management can reduce the cost of battery production and improve environmental performance. The quality of Li-ion battery… Read more »

Multiphysics modeling of fuel cells (free webinar)

Battery electric vehicles and fuel cell vehicles have unique marketplaces. Electric vehicles that must minimize weight (e.g. heavy duty trucks and airplanes) consider fuel cells as a primary power source for electrification, as they reduce the significant battery weight associated with battery electric vehicles. Engineers are continuing to develop new fuel cell designs for vehicles…. Read more »

NIO’s Battery as a Service (BaaS) brings down up-front EV costs, allows battery upgrades

Battery leasing has often been proposed as a way to bring down the up-front cost of an EV, and to allay consumers’ fears about battery degradation. Chinese EV-maker NIO has embraced this concept, and launched Battery as a Service (BaaS) for customers in China. NIO BaaS users can purchase a car without owning the battery,… Read more »
