Lithium-ion battery diaphragm is mainly composed of microporous film, with a high degree of physical isolation performance and ion conductivity. This microporous structure allows lithium ions to pass through, but at the same time prevents direct contact between the positive and negative electrodes, thereby avoiding dangers such as short circuits.
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.
The porosity, liquid absorption, ionic conductivity, thermal stability, electrochemical stability window, cycling stability, and multiplicity of the assembled cells of the PU-based diaphragm were analyzed to verify the feasibility of a PU-based nanofiber diaphragm for lithium-ion batteries. 2. Experimental Materials and Methods 2.1.
A high electrochemical stability window facilitates the long-term stable operation of Li-ion batteries at a high voltage. To evaluate the electrochemical stability of the diaphragm, the potential range was set to 2.5 V–6.0 V to perform LSV tests on the Celgard 2400 and PU/PAN fiber diaphragms.
Conclusions A centrifugal spinning method was used to prepare a PU/PAN lithium-ion battery diaphragm by blending with different ratios of PAN. The properties of the PU/PAN lithium-ion battery diaphragms were characterized in this study.
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.
Analysis of Electrochemical Stability Electrochemical stability is an important performance parameter for lithium-ion battery diaphragms, which must maintain the stability of the electrolyte and electrode in terms of electrochemical properties to avoid degradation during the charge and discharge process.
