Preparation and properties of spherical LiNi0.75Co0.25O2 as a cathode for lithium-ion batteries

Structural and electrochemical behavior of LiMn0.4Ni0.4Co0.2O2

“…20 shows the cyclic voltammogram at a sweep rate of 0.1 mV s −1 , and well-defined redox peaks are observed. The main oxidation peak is observed at 3.94 V after the first charge (all voltages mentioned are versus Li/Li + ) with a peak at 4.10 V only observed on the first charge, and the main [68], which indicates that LiMn 0.4 Ni 0.4 Co 0.2 O 2 has a smaller polarization than LiNi 0.75 Co 0.25 O 2 . The lack of a peak around 3 V shows that the manganese in our synthesized materials is not in the 3+ oxidation state [69].…”

Study on the rapid synthesis of LiNi1−xCoxO2 cathode material for lithium secondary battery

“…LiNi 1−x Co x O 2 (0 < x < 1) compounds are considered as one of the most promising cathode materials for lithium secondary batteries. It has the advantages of less toxicity and higher capacity compared with LiCoO 2 [5][6][7].…”

Microstructure and electrochemical characterization of spherical-like orthorhombic LiMnO2 via co-precipitation

“…Similarly, for lithium-ion batteries, spherically shaped positive material particles such as LiCoO 2 [13], LiMn 2 O 4 [14], Li(Ni 0.75 Co 0.25 )O 2 [15] and Li(Co 1/3 Ni 1/3 Mn 1/3 )O 2 [16,17], also show better cycleability and higher discharge capacities than those of individual particles. Additionally, the agglomerated spherical particles have much higher tap density, which is advantageous for the preparation of high-volumetric energy density electrodes.…”
