Commonly used coating materials include inorganic (represented by alumina and boehmite) and organic (represented by PVDF and aramid). Boehmite has good safety and economy and can replace alumina in some markets. Boehmite + magnetic material has a low water absorption rate, which can effectively ensure the safety of the diaphragm.
The zinc borate modified diaphragm was used as the structural-functional ceramic composite diaphragm, and the zinc borate and PVDF were prepared at a mass ratio of 90:10, and the ordinary diaphragm and the zinc oxide modified diaphragm were used as comparison samples. The battery electrolyte was 1 M LiPF6 in EC/DEC (1:1 vol ratio).
The diaphragm of a lithium-ion battery has important functions, such as preventing a short circuit between the positive and negative electrodes of the battery and improving the movement channel for electrochemical reaction ions.
For most of the organic battery materials, the crystallization degree is much lower compared with the inorganic battery materials. The amorphous structure is the most likely case for organic materials. Thus, the ionic type impact on the performance is not as strong as the inorganic materials.
The results indicate that the electrochemical performance of zinc ion batteries can be significantly increased by using SR-P-GF diaphragm materials. This study is expected to be a low-cost and efficient method to condition the diaphragm materials for zinc ion batteries to achieve higher performance zinc ion batteries. 2. Experiment section 2.1.
The LiFePO 4 /Li battery with composite diaphragm exhibits excellent rate and cycle performance. Due to the unique chemical structure of zinc borate, the Zn–O bond and -BO 3 group in the structure have a polar bond and Lewis acid action, respectively.
