Coating diaphragm materials are usually selected as coatings with good ionic conductivity. This can improve the conductivity of lithium ions in the diaphragm and reduce the internal resistance, thereby improving the charging and discharging efficiency of the battery.
Imagine storing excess energy like you stash snacks for a Netflix marathon - that''s essentially what diaphragm energy storage does for power grids. While lithium-ion batteries hog the spotlight, this flexible membrane-based system is quietly revolutionizing how we manage renewable energy.
Herein, we successfully prepared a fully biomass-based ss-PCM, superhydrophobic thermal energy storage (STES) coating by employing beeswax (BW) as phase change materials (PCMs) and DFs as supporting materials via a facile spraying method.
The above results show that ZnB modified diaphragm can effectively improve the storage capacity and affinity of the diaphragm to the electrolyte, which will help improve the cycle stability of the battery.

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.
Therefore, the research on the diaphragm is an important direction related to the performance of the lithium-ion battery. In recent years, the functional design of the diaphragm is usually the method of surface modification of the common diaphragm, adding the intermediate layer and self-constructing the diaphragm, etc.
Metal oxides containing polar chemical bonds (Al2 O 3, TiO 2, ZnO, CuO, and MnO2) improve the thermal stability of ordinary diaphragms and increase the amount of lithium-ion migration on the diaphragm surface.
This is because the zinc borate ceramic modified diaphragm has better electrolyte affinity and liquid retention ability, which makes the impedance between the diaphragm and the anode interface is small, the loss of electrolyte during charging and discharging is small, and the side reactions are less, which is conducive to the long cycle.
The test results show that coating the surface of the diaphragm with high flame retardant ZnB can effectively improve the thermal stability of the modified diaphragm. Therefore, the ZnB modified diaphragm can roughly maintain the size of the diaphragm and will not produce holes under high-temperature conditions.
