Microstructure engineering of electrodes is one of the efficient routes to improve rate performance of lithium-ion batteries (LIBs). Currently, there is a lack of descriptors to rationally guide the regional electrode design. Here, we propose two descriptors, the time differential of the average state of lithium (SoL) and the span of SoL …
Organic carbonates are the primary solvents used in lithium-ion battery electrolytes. The reversibility of current lithium-ion batteries is dependent upon the electrolyte used in the batteries. 1 During the initial charging cycles of the cell a solid electrolyte interface (SEI) is formed by reduction of organic carbonates on the surface of …
1 Introduction. Lithium (Li) metal is the ultimate anode for rechargeable batteries. Its high specific capacity (3860 mAh g −1) and low voltage (−3.04 V vs standard hydrogen electrode) warrant optimal cell energy density.However, the adoption of Li metal anode is currently plagued by Li dendrite growth during charge/discharge cycles.
