6 FAQs about [Lithium battery separator storage requirements]

Which separators should be used for lithium ion batteries?

Therefore, it is urgent to balance the security–reliability–performance of separators for the development of batteries. Currently, the most used separators for LIBs are microporous polyolefin membranes, such as PE and PP, due to their superior mechanical strength and chemical stability.

What is a good separator for batteries?

At present, polyolefin microporous membranes, such as polyethylene (PE) and polypropylene (PP), are the most widely used separators. The low melting point of polyolefins (135 °C for PE and 165 °C for PP) leads to poor thermal stability of separators, seriously affecting the safety of batteries.

What is the relationship between separator and battery safety?

The separator plays the pivotal role in normal LIBs and SIBs device and there is a close relationship between separator and battery safety , . The separator acts as a physical barrier to insulate cathode and anode from direct contact and accommodate electrolyte to facilitate ions shuttle inside the battery.

Why is a lithium ion battery separator important?

The separator is an indispensable component in lithium-ion batteries and sodium-ion batteries and directly affects the electrochemical performance and, especially, safety. It is imperative to develop high-safety separators for rechargeable lithium-ion batteries and sodium-ion batteries.

What is the minimum tensile strength of a battery separator?

The minimum tensile strength of the separator with a thickness of 25 µm is 98.06 MPa. This value usually occurs during the battery assembly , . In addition, the separator must also withstand punctures due dendrite that may formed during battery usage. The trend of using electric vehicles is increasing.

How to determine the safety of a Lib separator?

The thermal stability is another factor to assess the safety of the separator. A series of potential thermal runaway reactions exist in LIBs under the abuse circumstances (e.g., overcharging, overheating, and crashing), causing the heat accumulation and raised temperature.
