“…In the near future, it is not only of great significance to mitigate structural transformation and to improve Li + (de)intercalation kinetics, but equally important to manipulate electronic structure, tune redox behavior and reduce undesired irreversible oxygen reactions by adopting proper substitution/doping elements. To resolve interfacial problems, as summarized in Table 3, a great variety of materials has been utilized to modify the surface of LLROs, such as oxides, 243-248 fluorides, 246, 249-251 phosphate, [252][253][254][255][256][257] silicates, 258 carbon, 259-261 polymer, 262 and so on. The main function of such a protective coating layer is to avoid a direct contact between active material and electrolyte, thus reducing parasitic electrolyte oxidation and TM dissolution.…”

“…Solid-state Li ion conductors such as lithium boron oxide, lithium titanium oxide, lithium zirconium oxide, lithium silicon oxide, and metal phosphates as protective coating materials [30,43,[167][168][169][170][171][172][173][174][175][176][177][178][179][180][181][182][183][184][185][186] have been demonstrated to be effective in overcoming these unavoidable challenges. As shown in Fig.…”

“…Additionally, the electrode polarization and voltage degradation of NCA cathodes are also effectively alleviated because of the LZP coating. Li 3 V 2 (PO 4 ) 3 (LVP) is chemically stable and electrochemically active in terms of partial oxidation of V 4+ to V 5+ at 4.6 V [186]. Therefore, employing it as a coating material, LVP will not only be a good Li ion conductor in cathode materials but also can deliver additional reversible capacity.…”

“…Application of Li-containing phosphates such as LiNiPO 4 19 , Li 3 V 2 (PO 4 ) 3 20 , and LiAlTi(PO 4 ) 3 21 coating materials has been recommended to alleviate the problem of constricted Li ion diffusion, and they have been shown to improve the rate capability and prevent capacity fading during cycling. Another approach has been suggested to eliminate the two concerns simultaneously, i.e ., finding coating materials that can directly react with residual Li so that they can be transformed to Li-containing phases and in parallel the amount of Li residue is reduced.…”
