Cerium fluoride coated layered oxide Li1.2Mn0.54Ni0.13Co0.13O2 as cathode materials with improved electrochemical performance for lithium ion batteries

Li3V2(PO4)3-coated Li1.17Ni0.2Co0.05Mn0.58O2 as the cathode materials with high rate capability for Lithium ion batteries

“…For the LNCMO, three oxidation peaks appear at 3.8, 4.1 and 4.7 V (vs. Li/Li + ) in the initial anodic process. Compared with the results of other authors on the similar compositions [47,[53][54], the redox peak positions are similar. The peaks at 3.8 V could be attributed to the oxidation of Mn 3+ and the peak at 4.1 V could be attributed to the oxidation of Ni 2+ and Co 3+ .…”

Enhanced electrochemical properties of ZnO-coated LiMnPO4 cathode materials for lithium ion batteries

“…It implies that coating layer controls the structural degradation at higher voltage and maintains crystal structure with less defects [32,33]. It also confirmed the presence of ZnO coating, which leads to avoiding direct reaction between active materials and electrolyte, protects manganese from dissolving into the electrolyte, resulting in the prevention of Mn dissolution, hence minimizing the electrolyte oxidation [34,35]. Figure 5 describes the discharge capacities of pristine and zinc oxide-coated samples in the voltage range of 2.5-4.5 V. The 2 wt% ZnO-coated LiMnPO 4 exhibits better discharge capacity performance up to 100 cycles followed by 1 and 3 wt% ZnO-coated samples.…”

Investigation on the enhanced electrochemical performances of Li 1.2 Ni 0.13 Co 0.13 Mn 0.54 O 2 by surface modification with ZnO

“…The phase [22,23]. In addition, the distinct splitting between the adjacent peaks of (108)/(110) and (006)/(102) indicates the typical layered structure for the as-prepared composites have a well crystalline layered structure [24,25]. Besides the main Li after 130 cycles and is only 76% of its initial discharge capacity.…”
