Abstract

The novel water-based binder CMC-Li is synthesized using cotton as a raw material. The mechanism of CMC-Li as a binder is reported. CMC-Li as a binder can increase the contents of Li⁺, improving the diffusion efficiency and specific capacity. The battery with CMC-Li as the binder retained 97.8 % of the initial reversible capacity after 200 cycles at 176 mAh g^-1, which is beyond the theoretical specific capacity of lithium iron phosphate (LiFePO₄, LFP). The cyclic voltammetry and electrochemical impedance spectroscopy curves are weaker. The batteries obtain good electrochemical properties, are pollution free and have excellent stability.
