Electrode preparation and cell test
May 12 , 2021
Super P conductive carbon , polyvinylidene fluoride , and Clevios_ P solution (CP,from H. C. Starck, Inc.) were used as received. Sodium (Na) salt of carboxymethyl cellulose (NaCMC, with a typical molecular weight of 250 000 and degree of substitution of 0.90) was purchased from Sigma-Aldrich. The Li salt of CMC (LiCMC)was obtained by passing the NaCMC solution through a column of strongly acidic ...
