Long cycling life of Li2MnSiO4 lithium battery cathodes under the double protection from carbon coating and graphene network†
Abstract
Li2MnSiO4 possesses a high theoretical capacity of 332 mA h g−1 as a lithium battery cathode, but it suffered from rapid capacity fading due to the structural instability and manganese dissolution during cycles. Herein, we developed a unique reduced graphene
