High-Performance Cells Containing Lithium Metal Anodes, LiNiCoMnO (NCM 622) Cathodes, and Fluoroethylene Carbonate-Based Electrolyte Solution with Practical Loading.

We report on the highly stable lithium metal|LiNiCoMnO (NCM 622) cells with practical electrodes' loading of 3.3 mA h g, which can undergo many hundreds of stable cycles, demonstrating high rate capability. A key issue was the use of fluoroethylene carbonate (FEC)-based electrolyte solutions (1 M LiPF in FEC/dimethyl carbonate).
