Researchers virtually ‘unwind’ lithium battery; strategies for improving design of cylindrical cells

Green Car Congress

An international team led by researchers at UCL has revealed new insights into the workings of a commercial Li/MnO 2 primary battery by virtually “unrolling” its coil of electrode layers using an algorithm designed for papyrus scrolls. Unseen trends in the spatial distribution of performance in the cells were observed.

Lightning-fast recharging: Lotus leading the charge for faster top-ups with new 480kW Liquid-Cooled Power Cabinet

EV Central

Thanks to pioneering new technology that circulates cooling liquid through the charging connecter to prevent overheating, the new Lotus ultra-fast Supercharger rival can recharge at a class-leading 480kW. Finally, there’s a Liquid-Cooled Charging Unit that bundles the Power Cabinets together tocharge up to four vehicles at once.

Japan team evaluates battery-assisted low-cost hydrogen production from solar energy

Green Car Congress

For comparison, the US DOE’s 2020 target for the levelized cost of hydrogen (production only) is $2.30/kg. The joint research team designed an integrated system capable of adjusting the amount of battery charge/discharge and the amount of electrolysis hydrogen production in relation to the amount of solar power generated. to US$3.00/kg

Georgia Tech researchers develop aluminum-foil-based anodes for all-solid-state Li-ion batteries

Green Car Congress

Metal negative electrodes that alloy with lithium have high theoretical charge storage capacity and are ideal candidates for developing high-energy rechargeable batteries. These results demonstrate the possibility of improved all-solid-state batteries via metallurgical design of negative electrodes while simplifying manufacturing processes.
