“…To design the R2R ALD setup, several subsystems [e.g., gas and sample delivery units, plasma reactor (oxygen), and shower arrays apparatus (20 nozzles spaced 10 mm apart)] were separately designed and integrated according to the schematic illustration provided in Figure S1 (see the Supporting Information). 35 As shown in Figure S1, a conveyor system was designed for delivering the NCM523 sheets. The conveyor apparatus included a controller, a mechanical test unit (e.g., tensile strength measurement), and a temperature control system (e.g., heating/cooling).…”

Conformal coating of ceramic layers (nm-thick) on Ni-rich layered cathode materials is an effective strategy for improving high-temperature longevity of Li-ion batteries (LIBs). In this work, we develop a roll-to-roll atomic layer deposition (R2R ALD) apparatus for growing uniform nanolayers of TiO 2 . We explore the effect of ALD parameters (temperature: 120−180 °C and line speed: 2−40 mm s −1 ) on the TiO 2 surface coating and subsequently investigate the electrochemical performance of the as-prepared cathodes. The capacity retention of TiO 2 -coated porous electrodes is substantially improved compared to that of the pristine cathode material for high-temperature cycling. Electrochemical impedance spectroscopy confirms that the ALD-TiO 2 coating suppresses the undesired side reactions initiated at the electrode/electrolyte interface, reduces charge transfer resistance, and ultimately facilitates the Li + transport through the composite cathode nanostructure. The robust design of the ALD-TiO 2 cathode material enables high-temperature operation (>55 °C) with enhanced specific capacity, superior rate capability, excellent cyclability, and ultra-high coulombic efficiency within a wide potential window (3.0−4.35 V). The R2R ALD technique developed in this work paves the way for large-scale fabrication of ceramic-coated cathode sheets with a production rate reaching 2.4 m min −1 for a continuous coating operation.

“…Furthermore, in the same separator type and with the objective of enhancing thermal runaway, melaminebased porous organic polymer (POP) coatings [213] were implemented. In fact, different materials have been used as a layer on the surface of polyolefin separators to improve its wettability, including polyethyleneimine (PEI)/dopamine coating layer [188], Al 2 O 3 layers in electrospun PVDF nanofibers [193], ammonium persulfate (APS) coating [194], a phenolic resin (AF) layer with immersion in situ reaction [186], a thin layer of lowdensity polyethylene microspheres [199], polyamine (PAI) containing natural clay nanorods (attapulgite, ATP) [197], and polyvinyl alcohol (PVA) [214], TiO 2 [215], Al 2 O 3 [216], UVinduced graft with polar methyl acrylate (MA) [217], and polyimide (PI)-SiO 2 layers [218].…”

Environmental issues related to energy consumption are mainly associated with the strong dependence on fossil fuels. To solve these issues, renewable energy sources systems have been developed as well as advanced energy storage systems. Batteries are the main storage system related to mobility, and they are applied in devices such as laptops, cell phones, and electric vehicles. Lithium-ion batteries (LIBs) are the most used battery system based on their high specific capacity, long cycle life, and no memory effects. This rapidly evolving field urges for a systematic comparative compilation of the most recent developments on battery technology in order to keep up with the growing number of materials, strategies, and battery performance data, allowing the design of future developments in the field. Thus, this review focuses on the different materials recently developed for the different battery components—anode, cathode, and separator/electrolyte—in order to further improve LIB systems. Moreover, solid polymer electrolytes (SPE) for LIBs are also highlighted. Together with the study of new advanced materials, materials modification by doping or synthesis, the combination of different materials, fillers addition, size manipulation, or the use of high ionic conductor materials are also presented as effective methods to enhance the electrochemical properties of LIBs. Finally, it is also shown that the development of advanced materials is not only focused on improving efficiency but also on the application of more environmentally friendly materials.

“…One possible way is to fabricate ceramic composite membranes, such as directly coating ceramics (Al 2 O 3 , , SiO 2 , − etc. ), promoting the in situ growth of a thermal insulation layer − on the surface of commercial separators, or embedding ceramic nanoparticles into polymeric materials . Another effective method to improve the thermal stability of the separator is to coat high-temperature resistant polymer layers or branched organic molecules, such as ethylene glycol dimethacrylate, polyethylene glycol, and polyvinylidene fluoride (PVDF) on PE or PP separator surfaces.…”

The separator plays a vital role in preventing thermal runaway in lithium-ion batteries (LIBs). Herein, a PI/hBN (polyimide/hexagonal boron nitride) separator with excellent thermal stability and enhanced thermal conductivity is successfully prepared by ion track etching and doctor blade coating to achieve highly safe LIBs. The PI/hBN separator displays good electrolyte wettability, high mechanical strength, excellent thermal stability, and enhanced in-plane thermal conductivity, as well as good electrochemical performance when applied in LIBs. Specifically, PI track-etched membranes have been used to prepare separators with rigid structures and functional groups in polymer chains, thereby enabling the separators to be stable at temperatures as high as 500 °C. Moreover, hBN-coated nanoplates enhance the in-plane thermal conductivity of the separator to reduce the local heat accumulation in the battery while also promoting interfacial compatibility to facilitate the conduction of lithium ions. Lithium iron phosphate/lithium cells with the PI/hBN separator deliver better rate capability and superior capacity retention. The PI/hBN separator is a promising candidate for achieving highly safe LIBs, and this work paves the way for engineering roll-to-roll techniques to suppress thermal runaway and improve battery safety.
