Improvement of high voltage electrochemical performance of LiNi0.5Co0.2Mn0.3O2 cathode materials via Li2ZrO3 coating

Multifunctional Li2O-2B2O3 coating for enhancing high voltage electrochemical performances and thermal stability of layered structured LiNi0.5Co0.2Mn0.3O2 cathode materials for lithium ion batteries

“…To solve these defects, some conductive polymers and fast ionic conductor materials were widely used as surface coating layer on the cathode active materials. [24][25][26][27][28][29][30] materials is coated with various amount of LBO glass via a simple wet chemical process followed by heat-treatment. As expected, the LBO coated materials exhibit obvious improvement both in electrochemical performances and thermal stability under high voltage.…”

An Ostwald ripening route towards Ni-rich layered cathode material with cobalt-rich surface for lithium ion battery

“…Nonetheless, the above-mentioned electrochemically inactive layer causes lower capacity and Li + diffusion. Therefore, electron conducting materials such as carbon and graphene [50], lithium ion conductors such as Li 2 O· 2B 2 O 3 [51], Li 3 VO 4 [42] and Li 2 ZrO 3 [52,53], have been developed as coating materials for Ni-based cathode materials. Some lithium based materials have also been used to react with residual impurities on the surface of Ni-rich cathode materials and form a uniform coating layer on the bulk surface at the same time [54][55][56].…”

Enhanced electrochemical properties of Li[Li0.2Mn0.54Ni0.13Co0.13]O2 via lithium boron oxide glass surface treatment

“…Various effective methods have been adopted to solve these critical problems via coatings of sundry materials [9][10][11][12][13], such as metal oxides [14,15], metal phosphates [16,17], and metal fluorides [18]. A proper coating layer can defend the electrode surface from direct contact with the electrolyte and reduce the side-reactions between the electrolyte and electrode [19,20].…”
