A hydrolysis-hydrothermal route for the synthesis of ultrathin LiAlO₂-inlaid LiNi_0.5Co_0.2Mn_0.3O₂ as a high-performance cathode material for lithium ion batteries

Abstract

Lithium residues on the surface of LiNi0.5Co0.2Mn0.3O2 have been removed as raw materials to synthesize LiAlO2-inlaid LiNi0.5Co0.2Mn0.3O2 cathode materials in situ for lithium ion batteries.

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.…”

One-step synthesis of Li-doped NiO as high-performance anode material for lithium ion batteries

“…To meet the requirements of new generation lithium ion batteries, a series of cathode materials [1][2][3][4][5][6][7][8] and anode materials [9][10][11] have been extensively investigated for lithium ion batteries (LIBs). Transition metal oxides (TMOs), such as CoO x [12][13][14][15][16][17], CuO [18][19][20][21][22], SnOx [23][24][25], MnOx [26,27], CoMn 2 O 4 [28,29], ZnMn 2 O 4 [30] and MnCo 2 O 4 [31], have been widely studied as promising alternative anode materials for replacing the graphite used in LIBs for their high theoretical capacities.…”

Single-crystal neutron diffraction on γ-LiAlO2: structure determination and estimation of lithium diffusion pathway

“…Being an ultraslow lithium-ion conductor, γ-LiAlO 2 has been discussed for diverse applications: as coating for lithium-conducting electrodes [1,2], as an additive in composite electrolytes [3], as template for epitaxial growth of III-V semiconductors [4], as membrane material for molten-carbonate fuel cells [5], and as tritium-breeder material in fusion reactors [6,7]. However, a deeper, microscopic understanding of lithium diffusion in this solid is still lacking.…”
