α-MnO 2 /graphene nanocomposites are synthesized via a facile wet-chemical route, and α-MnO 2 nanosheets are uniformly distributed on the surface of graphene. Their high performance as lithium ion battery anodes is obtained. Their reversible capacity at C/10 rate is up to 726.5mAh/g, and maintains up to 635.5mAh/g after 30cycles. Such a performance can be partly attributed to high...
