This inorganic trilayer membrane is believed to be an inexpensive, novel separator for application in lithium-ion batteries from increased dimensional and thermal stability.
Lithium-ion batteries (LIBs) have been the leading power source in consumer electronics and are expected to dominate electric vehicles and grid storage due to their high energy and power densities, high operating voltage, and long cycle life .
Separator technologies in Li-ion batteries The separator, typically a thin microporous polymer membrane, plays a crucial role in Li-ion batteries by facilitating ionic transport within the cell and acting as an electrolyte reservoir, isolating or preventing physical contact between the negative and positive electrodes (Pan et al., 2017).
Lithium batteries primarily consist of lithium, commonly paired with other metals such as cobalt, manganese, nickel, and iron in various combinations to form the cathode and anode. What is the biggest problem with lithium batteries?
Independently of the battery type, the main components of a battery are the two electrodes (anode and cathode) and the separator, as illustrated in Fig. 1. Fig. 1. Schematic representation of the main component of a lithium-ion battery and the charging and discharging modes.
Polyimides (PIs) as coatings, separators, binders, solid-state electrolytes, and active storage materials help toward safe, high-performance, and long-life lithium-ion batteries (LIBs). Strategies to design and utilize PI materials have been discussed, and the future development trends of PIs in LIBs are outlooked.
When PI active storage materials are used as anodes, the lithium-ion storage mechanism is mainly attributed to the "hyperlithiation" phenomenon. The suitable operating voltage is at 0 ~ 1 V. More benzenes …

Polymer separators, similar to battery separators in general, act as a separator of the anode and cathode in the Li-ion battery while also enabling the movement of ions through the cell. Additionally, many of the polymer separators, typically multilayer polymer separators, can act as "shutdown separators", which are able to shut down the battery if it becomes too hot during the cycling process. These multilayered polymer separators are generally composed of one or mor…
