Lithium-ion batteries (LIBs) are widely adopted power sources for portable digital products and electrical vehicles (EV). However, the high cost associated with raw materials and manufacturing and low-temperature performance are primary concerns for largescale deployment of LIBs, especially for EV and grid-scale storage applications. Herein, a novel lithium-ion full cell assembled by 3 mu m-LiNi0.6Co0.2Mn0.2O2 (LNCM-3) cathode and electrochemically exfoliated graphene (EG) anode was fabricated, generating an energy density of similar to 278 Wh kg(-1), which is calculated on the basis of the design of commercial 18650 LIBs. Besides, it also exhibits outstanding rate capability, superior low-temperature electrochemical performance and ultralong cycle life (no capacity fading within 300 cycles at temperatures from 25 to -30 degrees C at 180 mA g(-1)). The proposed novel full cell configuration will enable the next-generation high performance batteries for EV applications.
