10、ACK DESIGN and MATERIALS innovationENERGY DENSITY of Li-ion battery will continue to improve through CELL DESIGN&INTEGRATION,MATERIALS development both on ANODE,CATHODE and SEPARATOR.SILICON will soon take more part in ANODE then Li-METAL NMCwill continue to be improved w/lower cobalt to reduce cost

11、 SOLID ELECTROLYTE is the KEY to energy density improvement but STILL CHALLENGINGNEW CHEMISTRIES/multivalent/H2are rigorously explored but will take a while to become practical for EVApec.orgAPECnewsAPECRebecca_APECapecAPECAPEC-Asia-Pacific Economic CooperationFind out moreAPEC Online and Social MediaCopyright 2022 APEC Secretariat
