“…And the larger particles could reduce the specific surface area of cathode, which further diminishes the side reactions between cathodes with electrolyte. 30 Besides, the cathodes after PPy coating also showed the rougher interface in Figs. 4c and 4d, which maybe belonging to the PPy coating layer.…”

Ni-rich cathode materials have attracted much attention due to the high energy density and low cost. However, the poor cycling performance and low rate capacity have produced a serious impact on the practical commercial application. In this work, the B3+ incorporation and polypyrrole coating were both applied to enhance the electrochemical properties of LiNi0.85Co0.05Mn0.10O2 by using the co-precipitation process followed by a chemical vapor phase polymerization way. Herein, the B3+ incorporation into crystal structure could enlarge the lattice spacing, contributing to accelerating the Li+ insertion/extraction speed and enhancing the structural stability during cycling. The polypyrrole surface coating played a great effect on preventing cathode surface from the electrolyte erosion owing to a shield of polypyrrole. As a result, a maximum discharge capacity of 129.8 mAh g−1 at 5 C high rate and prominently enhanced cycling performance with capacity retention of 90.1% after 300 cycles were acquired for the Polypyrrole coated LiNi0.835Co0.05Mn0.10B0.015O2. By comparison, the pristine LNCMO cathode demonstrated a fast decaying capacity and delivered a capacity retention of only 81.9%.

“…The electrochemical properties of the materials sintered in the mixed atmosphere of 75% oxygen and 25% nitrogen are similar to those sintered in a pure oxygen atmosphere, which can reduce the cost of the preparation of materials. At present, more research is focused on the doping and codoping of Ti, Al, Zr, B, Mo, F, and other elements. − For example, Li et al synthesized Cr were doped in LiNi 0.8– x Co 0.1 Mn 0.1 O 2 ( x = 0, 0.01, 0.02, 0.03) materials to improve the electrochemical properties of the materials .

LiNi0.8Co0.1Mn0.1O2 (NCM811) is considered a cathode material with great commercial potential. However, Li/Ni mixing, residual lithium compounds, and side reaction limited the popularity of Ni-rich batteries. Thus, a simple strategy is employed to realize a comodification of Na+ and Y3+. As demonstrated in the XPS results, the residual lithium compounds (Li2CO3/LiOH) and side reaction products are inhibited. The capacity retention rate of the modified NCM811 is 86.4% after 300 cycles at 1C, 34.5% higher than that of the pristine. Na+ expands the space of the Li+ slab, thereby reducing the charge transfer resistance and inhibiting the mixed discharge of cations. Meanwhile, Y3+ decreased the lattice along c-axis to restrict the movement of cations (Ni2+) into the Li site, with improving the exchange of Li+. The formed LiYO2 coating layer restrains the direct contact between the electrolyte and the electrode material so that side reactions are inhibited, reducing the electrochemical resistance.
