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. The new battery system is detailed in an open-access paper in Nature Communications. Resources Liu, Y., Nat Commun 14, 3975 doi: 10.1038/s41467-023-39685-x

Electric Car Corporation Plc Launches the Citroën C1 ev’ie Electric Vehicle

Green Car Congress

UK-based Electric Car Corporation Plc ( ECC ) has officially launched an all-electric version of the Citroën C1, the C1 ev’ie. The 4-seater electric car offers a range of 60-70 miles when fully charged and a top speed of around 60 mph. Its Li-ion battery pack can be fully charged in 6-7 hours from a domestic 13 amp socket.

Spontaneous formation of hollow structures in alloy anode crystals can improve battery stability

Green Car Congress

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.

Study identifies main culprit behind lithium metal battery failure; counters conventional wisdom

Green Car Congress

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.
