Metal negative electrodes that alloy with lithium have high theoretical charge storage capacity and are ideal candidates for developing high-energy rechargeable batteries. Resources Liu, Y., The new battery system is detailed in an open-access paper in Nature Communications. Nat Commun 14, 3975 doi: 10.1038/s41467-023-39685-x

Too much ion flow causes anode materials to swell and then shrink during charge-discharge cycles, causing mechanical degradation that shortens battery life. The small test batteries we fabricated showed promising charge-discharge performance, so we would like to evaluate the materials in larger batteries. —Matthew McDowell.

The answer has to do with how lithium deposits on the anode when the cell is charging. Right: Porous, tortuous, whisker-like microstructure which lowers Coulombic efficiency.

The system comprises a 55 kW motor inverter and a 30 kW generator inverter that is capable of Level 1 and Level 2 charging rates (1.8 ~ 19.2 The new technology eliminates the separate charging mechanism typically used in PHEVs, reducing both cost and volume under the hood.
