Revealing the closed pore formation of waste wood-derived hard carbon for advanced sodium-ion battery

Revealing the closed pore formation of waste wood-derived hard carbon for advanced sodium-ion battery Abstract Although the closed pore structure plays a key role in contributing low-voltage plateau capacity of hard carbon anode for sodium-ion batteries, the formation mechanism of closed pores is still under debate. Here, we employ waste wood-derived hard carbon as a template to systematically establish the formation mechanisms of closed pores and their effect on sodium storage performance. We ...
