Ni‐rich cathode is considered a promising cathode for its high specific capacity. However, a sharp capacity attenuation induced by interface problems limits the application of the cathode material. Herein, we propose a practical surface modification strategy by introducing diboron trioxide (B2O3) to the surface of LiNi0.83Co0.12Mn0.05O2 (NCM) cathode materials. B2O3‐modified NCM shows superior cyclic stability with a capacity retention of 87.7 % at 1 C after 200 cycles in comparison to 69.4 % for a bare NCM. On the basis of material and electrochemical characterizations, we conclude that the superior cycle stability of B2O3‐modified NCM material benefits from the formation of B2O3 coating and B3+ doping on the surface. The B2O3 coating layer that is confirmed by scanning and transmission electron microscopy can suppress surface side reactions and reduce the content of Li2CO3 on the surface. The B3+‐doping surface is verified by X‐ray diffraction and X‐ray photoelectron spectroscopy and triggers a reduction of a small amount of Ni3+ to Ni2+. Furthermore, the combination of surface B2O3 coating and B3+ doping inhibits the irreversible phase transitions and extension of microcracks in the NCM material. The above surface modification strategy provides a direction for the acquisition of long‐life cathode materials.

“…The breaking strength of the Sn-incorporated samples in Table 2 is higher than the pristine sample, and the highest breaking strength was observed at Sn 1.0 wt %. Cathode active material particles that have high breaking strength are expected to show excellent cycleability because high breaking strength restrains structural deformation, particularly at a high voltage and high C-rate [26,27]. In order to investigate the oxidation states of nickel, cobalt, manganese, and tin, an XPS measurement was performed.…”

LiNi x Co y Mn z (NCM), one of the most promising candidates for high-capacity cathode materials in Li-ion batteries (LIBs), is synthesized with various amounts of Sn. Sn-incorporated NCM from the resynthesis of NMC in leach liquor containing Sn from spent LIBs is characterized by scanning electron microscopy, energy-dispersive X-ray spectroscopy, X-ray diffraction, X-ray photoelectron spectroscopy, particle strength tests, and electrochemical tests. Sn-incorporated NCM has a globular form, and the uniform distribution of Sn inside cathode materials is confirmed. As Sn is introduced, the (003) diffraction peak tends to shift to a smaller angle and particle breaking strength increases. It is found that Sn-incorporated cathode active materials have better cycle performance and rate capability than pristine cathode active material although the discharge capacity slightly decreases. Because there is a trade-off between decreased discharge capacity and improved cycling and rate performance, the incorporation of Sn in resynthesized NCM should be carefully designed and conducted.

“…The material showed greatly improved cycling performance, even at elevated temperatures. The Al 2 O 3 coating suppressed crack formation, reduced degradation of charge transfer sites and increased cycling stability at 1 C. Without coating, carbonates and LiF formed on the particle surfaces, concomitant with an increase in the detrimental cubic NMC phase at particle surfaces (47). A third strategy to increase the stability of NMC based layered compounds is to make a composite of Li 2 MnO 3 and LiNi x Mn y Co z O 2 , also known as Li-rich NMC.…”
