Abstract

New cellulose derivative CMC-Li was synthesized, and nanometer fiber composite material was applied to lithium-ion battery and coated with AQ by electrospinning. Under the protection of inert gas, modified AQ/ carbon nanofibers (CNF) /Li nanometer composite material was obtained by carbonization in 280°C as lithium battery anode materials for the first time. The morphologies and structure performance of materials were characterized by using IR, SEM, CV and EIS, respectively. Specific capacity was increased to226.4 mAh.g-1 after modification for the first discharge at the rate of 2C. Performance of cell with CMC-Li with the high degree of substitution (DS) was superior to that with low DS. Cellulose materials were applied to lithium battery to improve battery performance by electrospinning.
