Abstract

Experimental evidence suggests that the most promising next-generation anode materials for rechargeable Li-ion batteries are activelinactive nanocomposites. Such anodes would have a capacity 2-10 times greater than that of current graphitic anodes. What inhibits the commercial use of such materials systems is the fracture which occurs at the active site surface once Li-insertion/de-insertion takes place during electrochemical cycling. The present paper is the first study to fabricate activelinactive anodes based on mechanical analysis that predict configurations and volume fractions that will minimize crack formation.
