| titleOfInvention | High ionic conductivity composite gel polymer separator and preparation method thereof |
| abstract | The invention relates to the technical field of lithium batteries, in particular to a composite gel polymer separator with high ionic conductivity and a preparation method thereof. It includes the following steps: firstly adding nano-ceramic, the surface of nano-ceramic contains a large amount of hydrophilic hydroxyl groups, then adding coupling agent, grafting acrylic acid to the surface of nano-ceramic by in-situ polymerization, and then adding lithium hydroxide and modified nano-ceramic. Ceramic reaction to obtain modified nano-ceramics with surface modified lithium polyacrylate, modified nano-ceramics and polymers are compounded to form a gel polymer separator, the high ion conductivity composite gel polymer separator of the present invention can effectively improve the lithium ion conductivity. It can improve the battery cycle performance. |
