The use of an aqueous slurry in the manufacture of lithium ion batteries has the advantages of being environmentally friendly,harmless to the human body,and low in production cost.In this study,the factors affecting the specific capacity and rate performance of the aqueous Li4Ti5O12 battery were studied,including the Li4Ti5O12 structure,aqueous binder,conductive agent,and surface density.The results show that a spherical secondary particle structure of Li4Ti5O12 is beneficial to its discharge rate performance.In addition,an aqueous binder with high conductivity improves the specific capacity and high rate charge/discharge performance of the battery,and when the amount of binder is 3％,the Li4Ti5O12 battery performs better.A chain structure in the conductive agent also improves the specific capacity and discharge rate performance of the Li4Ti5On battery,and increases the degree to which the discharge rate performance of the conductive agent can be further improved.Lastly,the lower the surface density,the better the rate performance of the Li4Ti5On battery.
