Virginia Tech team demonstrates green manufacturing method for Li-ion batteries

Green Car Congress

Researchers at Virginia Tech have demonstrated a green and more sustainable manufacturing method for LIBs in which no hazardous organic solvent is used during electrode manufacturing and recycling. Given that the global lithium-ion battery production capability is ~400 GWh, humongous amount of NMP is needed. —Li et al.

Researchers propose approach for recycling all-solid-state Li-ion batteries

Green Car Congress

Especially for all solid-state lithium-ion batteries (lithium ASSBs), aspects of waste management and circular economy have not been addressed so far. Within such ASSBs, the use of solid electrolyte like garnet-type Li 6.5 La 3 Zr 1.5 O 12 (LLZTO) garnet electrolyte and LiNi 1/3 Mn 1/3 Co 1/3 O 2 (NMC) cathode. La 3 Zr 1.5 202202361
