Polymers for advanced lithium-ion batteries: State of the art and future needs on polymers for the different battery components

Polymers in Lithium‐Ion and Lithium Metal Batteries

“…As a type of widely used materials in conventional LIBs, polymers play an important role in providing internal circuit isolation (e.g., separators) and overall structural support (e.g., binders and packaging). [11,17] However, these traditional Lithium-ion batteries play a significant role in modern electronics and electric vehicles. However, current Li-ion battery chemistries are unable to satisfy the increasingly heightened expectations regarding energy demand and reliability.…”

Formation of Multiple‐Helical Core‐Shell Structure from Polyphenyl and Boron Nitride Nanotube

“…Due to their special physical, chemical, and electrical properties, [20,21] polyphenyl are widely used in batteries, [22] chemical equipment, [23] aerospace, [24] corrosion-resistant materials, [25] and so on. [26] Recently, polyphenyl is a hot research topic, more and more researchers commit to developing its more performance. For example, Gergely and his co-workers [27] reported the DOI: 10.1002/adts.202100078 exploitation of an alternative reaction route of deamination of arylamines to perform in situ derivatization of multi-walled carbon nanotubes with polyphenyl species of various masses.…”

Lithium-ion battery separator membranes based on poly(L-lactic acid) biopolymer

“…These issues depend on the characteristics of the materials for the different battery components [5]. A lithium-ion battery consists of a negative electrode (anode) and a positive electrode (cathode), which are separated by a porous membrane called a separator [6,7].The separator is essential to improve battery performance. It can be based on different types of porous materials, including microporous membranes, nonwoven membranes, electrospun membranes, membranes with external surface modification, composites or polymer blend membranes [8].…”

“…Different polymer materials including poly(ethylene), PE [13], poly(propylene), PP [14], poly(methyl methacrylate), PMMA [15], poly (ether-ether-ketone) (PEEK) [16], poly(acrylonitrile), PAN [17], polyimide (PI) [18], Nylon 6.6 [19], poly(vinylidene fluoride), PVDF [20], poly(vinylidene fluoride-co-hexafluoropropene), PVDF-HFP [21] and poly(vinylidene fluoride-co-trifluoroethylene, PVDF-TrFE [20] are being explored for battery separator applications [7]. Commercial separators basically rely on polyolefin polymers based on their mechanical stability and chemical stability, good electrochemical performance and low cost [22].…”
