Spectroscopic analyses of 0.5Li[Ni0.8Co0.15Zr0.05]O2–0.5Li[Li1/3Mn2/3]O2 composite cathodes for lithium rechargeable batteries

“…Limited [6], it is reported that composition with x = 1/6 delivers a reversible capacity of ∼ 230 mA h g − 1 in the voltage range between 4.8 V and 2.0 V. For composite composition of 0.6Li(Li 1/3 Mn 2/3 )O 2 -0.4LiCoO 2 a discharge capacity of ∼ 235 mA h g − 1 (4.5-2.0 V) has also been reported [9].…”

Influence of Ti substitution on the structure and electrochemical properties of lithium-excess layered manganese based oxide for lithium ion batteries

“…Although ternary LiNi 1/3 Co 1/3 Mn 1/3 O 2 cathode material has the advantage of high energy density, the use of LiFePO 4 and LiMn 2 O 4 , should be more suitable since they both are priority in safety and low cost due to their high thermal stability, environmentally benign, and inexpensive [5]. Among various cathode materials for LIBs, Lithium-excess manganese metal oxides, denoted as xLi 2 MnO 3 -(1-x)LiMO 2 (M = Co, Ni, Fe, Mn), have attracted many attentions and are considered as the next generation cathode materials because of the high specific capacity [6][7][8][9][10][11][12][13]. Moreover, due to the high content of manganese, lithium and manganese rich metal oxide have the advantages of low cost compared to LiCoO 2 and LiNi 1/3 Co 1/3 Mn 1/3 O 2.…”

Effect of boric acid on the properties of Li2MnO3·LiNi0.5Mn0.5O2 composite cathode powders prepared by large-scale spray pyrolysis with droplet classifier

“…Recently, layered cathode materials based on the Li 2 MnO 3 -LiMO 2 (M = Cr, Ni, Co, Fe, or combinations) composite have attracted much attention due to their improved electrochemical properties [1][2][3][4][5][6][7][8][9][10][11]. Li 2 MnO 3 improved the discharge capacities and cycle properties of layered LiM 1Àx Mn x O (M = Co, Ni) cathode materials by providing stabilization at high operating voltages above 4.6 V. Various types of composite cathode materials have been studied in a variety of processes to improve electrochemical properties [1][2][3][4][5][6][7][8][9][10][11].…”

“…Li 2 MnO 3 improved the discharge capacities and cycle properties of layered LiM 1Àx Mn x O (M = Co, Ni) cathode materials by providing stabilization at high operating voltages above 4.6 V. Various types of composite cathode materials have been studied in a variety of processes to improve electrochemical properties [1][2][3][4][5][6][7][8][9][10][11]. A fine, uniform dispersion of the Li 2 MnO 3 phase in the layered LiMO 2 matrix was necessary to improve the electrochemical properties of the composite cathode materials [1,12]. In addition, the electrochemical performance of a cathode in a secondary lithium battery was strongly affected by powder properties, such as the morphology, specific surface area, crystallinity, and material composition [13][14][15][16][17][18][19].…”
