Cathode influences, lithium surface film

Magic angle spinning (MAS) NMR has been proved to be an extremely powerful tool, able to probe both the bulk of the materials used as electrodes and the surface layers arising after contact with atmosphere or with the electrolyte of a lithium battery [62]. The amount of surface interphase formed on cathodes was proved to influence drastically the electrochemical performance. Either an excessive amount or an insufficient amount of surface species is detrimental to the performance, while there is optimal formation of surface films for each kind of electrodes in standard electrolyte solutions. The interphase formed as a function of...
