Embodiment 1

[0029] Synthesis of electrode additives for all-solid-state batteries: Preparation of metal-organic framework compound ZIF-8. The raw material zinc salt and the ligand 2-methylimidazole were respectively dissolved in methanol, and the solutions of the two raw materials were mixed and allowed to stand at room temperature for 24 hours. Separate and dry to obtain the required additive: ZIF-8 material.

[0030] Electrode preparation: The obtained ZIF-8 material was combined with commercial cathode material LiCoO 2 Mix evenly, and the ratio of ZIF-8 is 20%, to obtain the electrode active material. Afterwards, the electrode active material, the conductive agent Super-P and the binder (LA) are prepared into an electrode according to a mass ratio of 8:1:1. The scanning electron microscope image of the electrode is shown in figure 1 shown.

[0031] The prepared electrode is used as the positive electrode, the metal lithium sheet is used as the negative electrode, and the metal-orga...
