The article conveys some information:
The solid-electrolyte interphase (SEI) is pivotal in stabilizing Li metal anodes for rechargeable batteries. However, the SEI is constantly reforming and consuming electrolyte with cycling. The rational design of a stable SEI is plagued by the failure to control its structure and stability. Here the authors report a mol.-level SEI design using a reactive polymer composite, which effectively suppresses electrolyte consumption in the formation and maintenance of the SEI. The SEI layer consists of a polymeric Li salt, LiF nanoparticles and graphene oxide sheets, as evidenced by cryo-TEM, at. force microscopy and surface-sensitive spectroscopies. This structure is different from that of a conventional electrolyte-derived SEI and has excellent passivation properties, homogeneity and mech. strength. The use of the polymer-inorganic SEI enables high-efficiency Li deposition and stable cycling of 4 V Li|LiNi0.5Co0.2Mn0.3O2 cells under lean electrolyte, limited Li excess and high capacity conditions. The same approach was also applied to design stable SEI layers for Na and Zn anodes. In the experiment, the researchers used Vinylene carbonate(cas: 872-36-6Product Details of 872-36-6)
Vinylene carbonate(cas: 872-36-6) belongs to esters. Alkyl carbonates find applications as solvents for lithium ion battery electrolytes and the use of high quality battery grade electrolytes having extremely low water (<10 ppm) and acid (<10 ppm) contents are critical for achieving high electrochemical performance.Product Details of 872-36-6
