6 FAQs about [Solid-state battery and diaphragm]

Why is the diaphragm important in a lithium ion battery?

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.

Why does a composite diaphragm store more electrolytes under the same volume?

Therefore, the composite diaphragm can store more electrolytes under the same volume. Zinc borate has the synergistic effect of boric acid groups and polar metal bonds, which promotes the transmission of lithium ions in the electrode, thereby increasing the conductivity of lithium ions.

Which diaphragm is used as a structural-functional ceramic composite?

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).

What is SEM-EDS mapping of zinc borate modified diaphragm?

SEM-EDS mapping of zinc borate modified diaphragm. The thermal stability of the diaphragm is an important criterion for ensuring battery safety, and the thermal shrinkage test is usually used to evaluate the dimensional thermal stability of the poly (vinylidene fluoride) diaphragms for next‐generation lithium-based batteries .

Are all-solid-state batteries safe?

All-solid-state batteries (all-SSBs) have emerged in the last decade as an alternative battery strategy, with higher safety and energy density expected . The substitution of flammable liquid electrolytes (LEs) with solid electrolytes (SEs) promises improved safety.

What is a LiFePo 4 / Li battery with composite diaphragm?

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.
