“…When the battery is charged and discharged, migration of material oxygen and metal ions from the lattice to surface occurs, the reaction with electrolyte will generate byproducts to seriously affect the battery life. 119,120 Therefore, improving the side reactions at the contact interface between electrode surface and electrolyte and regulating the electrolyte are also effective strategies to solve the oxygen precipitation phenomenon of nickel-rich NCM cathode. By doping the lattice of ternary cathode with some metal ions, the electronic conductivity can be improved and the stability of ternary material would be enhanced.…”

With the commercialization of lithium-ion battery (LIB) powered electric vehicles, they have been recognized as an important green technology due to the merit of zero CO 2 emissions to mitigate global climate change. As for the cathode materials, nickel-rich LiNi x Co y Mn 1-x-y O 2 (NCM) stand out due to high energy density. However, key issues of cation migration, phase transition, formation of oxygen vacancies and battery overcharge would cause oxygen release problems when operating at high voltages, which seriously harms battery performance. When applied in large-scale battery packs, the problemes mentioned above of individual cells may affect the overall battery pack due to their close stack. Therefore, study to avoid the phenomenon of oxygen release generation is necessary, while, a systematic summary of its mechanism can help to improve the thermal stability of LIBs. Herein, this review initiates to systematically elucidate the mechanism of oxygen release in nickel-rich NCM followed by further summarizing the effective strategies to deal with the oxygen release phenomenon, and finally give an outlook on the future prospects of nickel-rich NCM.

Although various bismuth (Bi) electrode materials are reported to assemble aqueous alkaline rechargeable batteries (AARBs) owing to desirable potential window and high theoretical capacity, the Bi‐based electrode materials are still confronted with by their “death space” and poor stability. Herein, a zero‐dimensional/two‐dimensional (0D/2D) amorphous/crystalline BiOx‐Bi heterostructure is successfully synthesized by a one‐step reduction method for achieving nearly theoretical capacity. Under proper NaBHNaBH4 content, the Bi33+ is reduced to form ultra‐thin 2D metallic bismuth nanoflakes (Bi‐nf), and incompletely reduced amorphous 0D BiOx nanodots are embedded in Bi‐nf to form the target BiOx/Bi‐nf heterostructure. The embedded 0D nanodots inhibit the aggregation of 2D Bi‐nf, accelerate the mass transport rate with more oxygen vacancies and pores at heterogeneous interface, and the active centers of amorphous nanodots and ultrathin nanoflakes are recognized as completely accessible which is benefit for up to theoretical capacity. Accordingly, the optimized 0D/2D amorphous/crystalline BiOx‐Bi‐nf heterostructure electrode presents an admirable capacity of 350 mAh g−1 at 1 A g−1 and outstanding capacity retention of 79.9% at 20 A g‐1. Moreover, the assembled BCNP (basic cobalt/nickel phosphate)//BiOx/Bi‐nf battery exhibits exceptional energy density of 191.64 Wh kg‐1 at 1.28 kW kg‐1 power density and durable stability (80% after 14000 cycles).
