Low-cost N-doped interlayer derived from loofah sponge enables high-performance Li-S, Li-Se and LiI2 batteries

Green Car Congress

Researchers from Griffith University in Australia and Peking University in China have synthesized low-cost, hierarchically porous, and nitrogen-doped loofah sponge carbon (N-LSC) derived from the loofah sponge via a simple calcining process and applied it as a multifunctional blocking layer for Li–S, Li–Se, and Li–I 2 batteries.

Faradion demonstrates proof-of-concept sodium-ion electric bike

Green Car Congress

For the proof-of-concept, the cells were manufactured to be larger than necessary to avoid unnecessary costs and lengthy manufacturing processes at this early stage. The battery for the e-bike has a design energy of 418 Wh, 250 Wh of which has been used in the e-bike proof-of-concept. Click to enlarge. Earlier post.).

RIKEN team develops high-performance lithium-iodine battery system with higher energy density than conventional Li-ion

Green Car Congress

The working concept of I3 – /I – redox reaction in the aqueous Li-I 2 battery. The reversible redox reaction without the formation of resistive solid products promotes rechargeability, demonstrating 100 cycles with negligible capacity fading. The Li-I 2 batteries showed high energy density and excellent recharge ability.
