【 摘 要 】

In order to meet the demand for more ecological and economic fabrication of lithium ion (Li-ion) batteries, water is considered as an alternative solvent for electrode paste preparation. In this study, we report on the feasibility of water-based processing of LiNi1/3Mn1/3Co1/3O2-based pastes for manufacturing cathode electrodes. The influence of the total solid content, the amount of conductive agent and binder materials on paste rheology and the final electrode properties was investigated. Suitable paste formulations which enable favourable paste flow behaviour, appropriate electrode properties and good electrochemical performance have been found. Results show that a substitution of the conventional organic solvent-based manufacturing route for LiNi1/3Mn1/3Co1/3O2 cathodes by water-based processing exhibits a promising way to realise Li-ion batteries with comparable electrochemical behaviour, while avoiding toxic processing aids and reducing overall manufacturing costs.
