“…This highly electronic conductive sheet provides not only improved electrochemical performance but also better thermal stability resulting from reduced interfacial side reactions with the electrolyte under coating. Very recently, Chen and coworkers reported aluminum-doped zinc oxide (AZO)-coated LCO cathode [202]. AZO is a wellknown conducting oxide with suitable electronic conductivity to stand a chance of improving C-rate capability.…”

An ever-increasing market for electric vehicles (EVs), electronic devices and others has brought tremendous attention on the need for high energy density batteries with reliable electrochemical performances. However, even the successfully commercialized lithium (Li)-ion batteries still face significant challenges with respect to cost and safety issues when they are used in EVs. From a cathode material point of view, layered transition-metal (TM) oxides, represented by LiMO 2 (M = Ni, Mn, Co, Al, etc.) and Li-/Mn-rich xLi 2 MnO 3 Á(1-x)LiMO 2 , have been considered as promising candidates because of their high theoretical capacity, high operating voltage, and low manufacturing cost. However, layered TM oxides still have not reached their full potential for EV applications due to their intrinsic stability issues during electrochemical processes. To address these problems, a variety of surface modification strategies have been pursued in the literature. Herein, we summarize the recent progresses on the enhanced stability of layered TM oxides cathode materials by different surface modification techniques, analyze the manufacturing process and cost of the surface modification methods, and finally propose future research directions in this area.

“…Prevailing strategies for protecting LCO are bulk doping 7,8,18 and surface modification. 5,9,15,17,[19][20][21][22][23] An alternative strategy is to develop highly compatible electrolytes to form stable CEIs. Although fluorinated electrolytes, 24,25 multifunctional polymer electrolyte, 26,27 and additives 28,29 have demonstrated promising cyclability improvement, such explorations have been focused mainly on charging voltages up to 4.5 V Li 24,25,30 (Table S1, ESI †).…”

“…In the past ten years, high-energy Sibased full cells have attracted much attention because that Sibased materials have high capacities and low voltage platform. By matching promising Si-based anodes with conventional cathodes [251][252][253][254][255][256][257][258][259][260][261] (LFP, LCO, NCM, and S), as well as suitable electrolytes, binders, and separators, the assembled full cells can deliver high energy densities and outstanding cycling performance. Based on the qualities of active materials, the capacity of a full cell (C Full cell ) can be calculated by Equation 4, in which C Cathode is the specific capacity of a cathode, m Si and m Cathode are the qualities of Si-based anode and matching cathode materials, respectively.…”

Lithium‐ion batteries (LIBs) have been occupying the dominant position in energy storage devices. Over the past 30 years, silicon (Si)‐based materials are the most promising alternatives for graphite as LIB anodes due to their high theoretical capacities and low operating voltages. Nevertheless, their extensive volume changes in battery operation causes the structural collapse of Si‐based electrodes, as well as severe side reactions. In this review, the preparation methods and structure optimizations of Si‐based materials are highlighted, as well as their applications in half and full cells. Meanwhile, the developments of promising electrolytes, binders and separators that match Si‐based electrodes in half and full cells have made great progress. Pre‐lithiation technology has been introduced to compensate for irreversible Li+ consumption during battery operation, thereby improving the energy densities and lifetime of Si‐based full cells. More importantly, almost all related mechanisms of Si‐based electrodes in half and full cells are summarized in detail. It is expected to provide a comprehensive insight on how to develop high‐performance Si‐based full cells. The work can help us understand what happens during the lithiation process, the primary causes of Si‐based half and full cells failure, and strategies to overcome these challenges.
