Abstract: In order to employ Li-ion batteries (LIBs) in next-generation hybrid electric and/or plug-in hybrid electric vehicles (HEVs and PHEVs), LIBs must satisfy many requirements: electrodes with long lifetimes (fabricated from inexpensive environmentally benign materials), stability over a wide temperature range, high energy density, and high rate capability. Establishing long-term durability while operating at realistic temperatures (5000 charge-depleting cycles, 15 year calendar life, and a range from À46 8C to þ6… Show more

“…Examples of solid films on electrode surfaces include Li 2 CO 3 layers formed on pristine cathode oxide surfaces; [8][9][10][11] cathode-coating films made of electrolyte decomposition products; 3,12-17 SEI films on anodes arising from reductive decomposition of liquid electrolyte components; 3,5-7 artificial protective/passivating coatings, 18 including atomic layer deposition (ALD) layers 19,20 which can undergo phase transformations at low voltages; 21,22 ALD layers between solid electrolytes and electrodes in all-solid state batteries; 23 and even Li 2 O 2 films deposited on cathodes during fast discharge of Li-air batteries, 24,25 the re-oxidation of which is accompanied by significant voltage hysteresis and is a root cause of the lack of a suitable liquid electrolyte in Li-air batteries.…”

“…Coating the surface of the positive electrode and using electrolyte additives are two popular ways to suppress the parasitic reactions and thus improve the cell lifetime. 6,7 Zheng et al claimed that an AlF 3 coating on Li and Mn rich positive electrode materials could reduce electrolyte oxidation at high voltage by suppressing thick solid electrolyte interface (SEI) formation. 8 Recently, Mohanty et al showed a significant suppression of impedance by using an Al 2 O 3 coating on NMC or NCA (LiNi 0.85 Co 0.1 Al 0.05 O 2 ) materials which improved cell performance.…”

“…Lastly, liquid electrolytes are known to give rise to dissolution of the transition metal, thus decreasing the cathode capacity even further [18]. However, thin film methods such as atomic layer deposition can be used to deposit thin layers (e.g., Al 2 O 3 or AlF 3 ) onto cathode materials to protect them from side reactions such as transition metal dissolution [20][21][22][23][24]. Some of these problems can also be circumvented by using mixture cathodes, such as LiNi (1−y−z) Mn y Co z O 2 , which can also produce slightly higher capacities [5,18,19].…”
