Abstract The high-nickel cathode material of LiNi0.8Co0.15Al0.05O2 (LNCA) has a prospective application for lithium-ion batteries due to the high capacity and low cost. However, the side reaction between the electrolyte and the electrode seriously affects the cycling stability of lithium-ion batteries. In this work, Ni2+ preoxidation and the optimization of calcination temperature were carried out to reduce the cation mixing of LNCA, and solid-phase Al-doping improved the uniformity of element distribution and the orderliness of the layered structure. In addition, the surface of LNCA was homogeneously modified with ZnO coating by a facile wet-chemical route. Compared to the pristine LNCA, the optimized ZnO-coated LNCA showed excellent electrochemical performance with the first discharge-specific capacity of 187.5 mA h g−1, and the capacity retention of 91.3% at 0.2C after 100 cycles. The experiment demonstrated that the improved electrochemical performance of ZnO-coated LNCA is assigned to the surface coating of ZnO which protects LNCA from being corroded by the electrolyte during cycling.

Abstract Rechargeable aluminum ion batteries (AIBs) have attracted much attention because of their high charge density, low cost, and low flammability. Transition metal sulfides are a class of cathode materials that have been extensively studied. In this report, Bi2S3 nanorods and Bi2S3/MoS2 nanorods were synthesized by the hydrothermal method as new type of cathode materials for rechargeable AIBs. The diameter of Bi2S3/MoS2 nanorods is 20–100 nm. The Bi2S3 nanorods display high initial charge and discharge capacities of 343.3 and 251 mA h/g with a current density of 1 A/g. The static cycling for the Bi2S3/MoS2 nanorods electrode at 1 A/g denotes high stability with a specific capacity of 132.9 mA h/g after 100 cycles. The charging voltage platform of Bi2S3 nanorods and Bi2S3/MoS2 nanorods is at 1.1–1.4 V, and the discharge voltage platform is at around 0.8 V. The well-defined heterojunction maintains the stability of the Bi2S3 structure during long-term cycling, which is desirable for aluminum ion batteries. This strategy reveals new insights for designing cathode materials of high-performance AIBs.

Lithium Metal

Because lithium metal exhibits high specific capacity and low potential, it is the best candidate for fabricating anodes for batteries. Rechargeable batteries fabricated using lithium anode exhibit high capacity and high potential cathode; these can be potentially used to fabricate high energy density batteries (>500 Wh kg–1) that can be used for the development of next-generation electric vehicles. However, the formation and growth of lithium dendrites and the low coulombic efficiency recorded during lithium plating and stripping under conditions of high current density hinder the use of lithium metal as the anodic material for the development of practical rechargeable batteries. In this short review, we outline the current status and prospects of lithium anodes for fabricating batteries in the presence of non-aqueous liquid, polymer, and solid electrolytes operated under conditions of high current density.
