The invention discloses a negative electrode dispersant for lithium ion batteries, a preparation method and application thereof. The obtained modified sodium carboxymethyl cellulose. The present invention utilizes the reaction of grafting some functional groups with higher electronegativity on the sodium carboxymethyl cellulose, so that the sodium carboxymethyl cellulose has the effect of accelerating the conduction of lithium ions. Compared with the sodium carboxymethyl cellulose before modification, the sodium carboxymethyl cellulose glue, which has the effect of accelerating lithium ion conduction, can be used in lithium ion batteries without changing the dispersing ability, and at the same time, it can speed up the reaction kinetics , which can reduce the internal resistance of the battery and improve the stability of the battery. |
