Aqueous Binders for Electrochemically Stable VOPO₄ 2H₂O Anodes for Li-Ion Storage.

ABSTRACT: The use of polyvinylidene difluoride (PVDF) binder dissolved in toxic N-methyl pyrrolidone (NMP) organic solvent needs to be decreased during the manufacturing battery process to improve safety. Therefore, the development of aqueous-based binders for negative and positive electrodes is necessary to make the production environmentally friendly. This study reports the performance of hydrothermal VOPO₄ 2H₂O anode material in combination with aqueous-based binders such as sodium carboxymethylcellulose (CMC), polyacrylic acid (PAA) and their mixture CMC-PAA (1:1 wt%). The aqueous binders are compared to standard PVDF as a reference binder. The cells with aqueous- and PVDF-based electrodes are tested by galvanostatic, cyclic voltammetry, and electrochemical impedance spectr
