The film properties of lithium-ion batteries determine the capacity, cycling stability, and other important battery characteristics, and therefore the diaphragm must have an adequate thickness, ionic conductivity, high porosity, and both thermal and electrochemical stability [ 4, 5, 6 ].
The routine diaphragm has a general affinity for organic electrolytes, but its good wettability and liquid retention greatly impact the performance of lithium-ion batteries.
The discharge capacity of lithium-ion batteries assembled with PU/PAN fiber diaphragms was higher than that of the Celgard 2400 diaphragm at 0.2 C, 0.5 C, 1 C, 2 C, and 5 C rates. The lowest discharge capacity was recorded for lithium-ion batteries fitted with a Celgard 2400 diaphragm.
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.
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.
Analysis of the Thermal Stability The thermal stability of the diaphragm is critical to the safety of lithium-ion batteries and is an extremely important indicator. Batteries often charge and discharge at high rates, and the internal temperature of the battery is prone to rise.
