ZAF to use $300,000 grant to increase production of nickel-zinc batteries

Nickel-zinc (NiZn) specialist ZAF Energy Systems has received $300,000, the first installment of a $600,000 investment from Missouri’s Department of Economic Development. With the new funding, ZAF will increase production capacity to meet the increasing demand for its NiZn batteries. The company claims that the batteries have double the storage capacity and triple the power… Read more »

AKASOL begins mass production of batteries for Mercedes eCitaro electric bus

This fall, AKASOL is set to begin mass producing batteries for Mercedes-Benz’s eCitaro. AKASOL’s first-generation battery systems will contain ten battery modules for up to 243 kWh per vehicle and a charging rate of up to 300 kW. In order to make this possible, AKASOL uses a water-cooling system to keep its batteries at 25° C in various… Read more »

Ricardo announces 48 V e-motor with improved power density

As per the goals of the European Competitiveness in Commercial Hybrid and AutoMotive PowertrainS (ECOCHAMPS) project, Ricardo Innovations has developed a new 48 V e-motor and inverter combination that it says delivers a 50% power density increase compared to alternatives. ECOCHAMPS brought 25 European commercial and academic partners together to design powertrains with at least… Read more »

Tokyo Tech introduces fabrication process for low-resistance solid-state batteries

Solid-state batteries are theoretically safer, more stable, and have higher energy densities than conventional Li-ion batteries with liquid electrolytes. Unfortunately, they also tend to have relatively high resistance at the interfaces between their electrodes and solid electrolytes, which can limit the rate of charging and discharging. In order to solve this, researchers from the Tokyo… Read more »

bdtronic develops motor impregnator with 45-second cycle time

bdtronic, a global manufacturer of dispensing machines and systems that process polyurethane, epoxy, silicone and liquid resins, has developed what it claims is the world’s largest and fastest automotive motor impregnation machine. The B8300 impregnator is designed to speed up the motor production process – its main function is to fill electric motor stators with a solid gel… Read more »

Carnegie Mellon creates new method to 3D print battery electrodes

Porous electrodes have been 3D printed in the past using extrusion processes in which a strand of material is extruded from a heated nozzle. Interdigitated, or clasped, structures created with this technique provide space for ion flow, but their limited geometries are quite inefficient. Carnegie Mellon University’s new research has developed a completely different additive process… Read more »

Penn State researchers develop cold-weather fast charging method for Li-ion batteries

Fast charging cold Li-ion batteries comes with the risk of lithium plating. When metallic lithium is formed in a battery, it can severely reduce battery lifespan and increase instability. Researchers from Penn State have suggested a solution to that problem that can provide 15-minute fast charging and a twelve-year battery lifespan in temperatures as low as… Read more »
