A double-layered Ge/carbon cloth integrated anode for high performance lithium ion batteries†
Abstract
A double-layered Ge coated carbon cloth composite was synthesized by electrodepositing Ge from an ionic liquid using carbon cloth as substrate. As an integrated electrode, the composite exhibits a high initial charge capacity of 1169 mA h g−1 and retains 989 mA h g−1 after 100 cycles at 300 mA g−1.
