| titleOfInvention | Lithium battery additive amido vinyl sulfate, and preparation method and application thereof |
| abstract | The invention relates to the field of lithium ion batteries, and discloses a lithium battery additive amido vinyl sulfate, a preparation method and application thereof aiming at the problems of low coulombic efficiency and poor cycle stability in the existing batteries, wherein the chemical structural formula is as follows: the molecular structure consists of three parts of amido, alkyl chain and vinyl sulfate; wherein m and n are the same or different, m can be 0,1,2,3 …, and n can be 1,2,3 …. According to the amino vinyl sulfate additive provided by the invention, the amino part can improve the battery cycle stability by stabilizing metal ions in electrolyte, and the vinyl sulfate part can be decomposed to form a stable SEI film on the surface of a negative electrode, so that lithium ions can be uniformly deposited, and the battery cycle performance is improved; the stability of the lithium ion battery anode material under high voltage can be improved, the decomposition of electrolyte on the surface of the anode is inhibited, and the storage performance and the cycle performance of the high voltage lithium ion battery are improved. |
