Abstract
We demonstrate the feasibility of a lithium ion battery (LIB) using graphene nanosheets (GNS) as the anode in combination with a LiNi 0.5Mn1.5O4 (LNMO) high voltage, spinel-structure cathode. The GNS anode is characterized by a reversible capacity of the order of 600 mA h g-1 and a working voltage of around 0.9 V, while the 4.8-V cathode has a theoretical capacity of 146.7 mA h g -1. The full GNS/LiNi0.5Mn1.5O4 cell has an average working voltage of about 3.75 V and a capacity of the order of 100 mA h g-1. The findings of this paper suggest that the graphene may be proposed as a suitable anode for application in lithium ion batteries. © 2013 the Owner Societies.
