| titleOfInvention | Semi-solid lithium battery electrolyte and preparation method thereof |
| abstract | The invention relates to the field of lithium batteries, and discloses a semi-solid lithium battery electrolyte and a preparation method thereof. The method comprises the following steps: (1) uniformly mixing slurry of a mixture of lithium chloride, yttrium chloride, a doping phase M and absolute ethyl alcohol with a binder and a foaming agent, and performing compression molding and sintering to obtain a porous electrolyte membrane; (2) the method comprises the steps of firstly soaking a porous electrolyte membrane in ethylene glycol solution of sulfamic acid, then adding allyl polyethylene glycol monoether, adding urea, heating and reacting under the protection of inert gas, then adding acrylic acid, cooling and reacting, then continuing adding calcium chloride, standing and reacting, finally taking the electrolyte membrane out of an oven, drying and subsequently processing to obtain the semi-solid lithium battery electrolyte. The semi-solid lithium battery electrolyte prepared by the invention is Li with a rigid porous structure 3 M x Y 1‑x Cl 6 As a framework material, the flexible sulfonic end-capped polymer gel fills the internal pores, effectively improves the lithium ion conductivity of the electrode, and has high ionic conductivity and good application prospect. |
