“…Over the last few years, numerous research studies have been targeting the development of Ni-rich cathodes (usually NMC with Ni ratio of 6 or above) to incorporate them in so-called next-generation LIBs [ 5 , 8 , 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 ] for commercial EVs. Most of the experimental and numerical work cited deal with the adversities of high Ni content, namely, chemical and structural instability, both leading to capacity fading, poor rate performance, and potential decay [ 59 ].…”

“…Most solutions proposed for improving the electrochemical performance of Ni-rich cathodes involve either doping the electrode, surface coating, controlling particle size, crystalline structure, porosity, and/or film thickness [ 5 , 6 , 53 , 54 , 55 , 56 , 59 , 60 , 70 , 71 ].…”

“…In the same manner, as combining different transition metal ions in the same layered structure has led to successful compromise solutions between thermal, structural, and cycling behavior of Ni-rich cathodes, coating NMC electrodes with LiFePO

could potentially result in combining the high capacity and high cycle life of the respective cathode types. Zhong et al [ 53 ] have reported a nano LiFePO

composite prepared via mechanical fusion. Since both material systems are electrochemically active, a higher specific capacity may be achieved.…”

Global energy demand is rapidly increasing due to population and economic growth, especially in large emerging countries, which will account for 90% of energy demand growth to 2035. Electric vehicles (EVs) play a paramount role in the electrification revolution towards the reduction of the carbon footprint. Here, we review all the major trends in Li-ion batteries technologies used in EVs. We conclude that only five types of cathodes are used and that most of the EV companies use Nickel Manganese Cobalt oxide (NMC). Most of the Li-ion batteries anodes are graphite-based. Positive and negative electrodes are reviewed in detail as well as future trends such as the effort to reduce the Cobalt content. The electrolyte is a liquid/gel flammable solvent usually containing a LiFeP6 salt. The electrolyte makes the battery and battery pack unsafe, which drives the research and development to replace the flammable liquid by a solid electrolyte.

“…The most extensive efforts to improve the performance of LIBs have focused on the intrinsic chemistry, via the electrolytes, 4-10 binders, [11][12][13][14] anodes, [15][16][17][18] and cathode materials. [19][20][21][22][23][24][25][26] However, only incremental changes in the cell chemistry (e.g., increasing Ni content in cathode; increased Si loading in blended anodes with graphite) have found commercial success over the past decade. The slow commercial progress of new chemistries dictates the need for alternative electrode and cell designs that can enhance battery performance.…”

Continually increasing technological demands and widespread adoption of electric vehicles has spurred significant motivation to improve the performance of lithium-ion batteries (LIBs). In addition to improving intrinsic battery chemistry, optimizing electrode morphology and cell design can unlock increased energy density and rate capability to enable the adoption of next generation LIBs for societal decarbonization. Although free-standing electrode (FSE) architectures hold the potential to dramatically increase the gravimetric and volumetric energy density of LIBs by eliminating the parasitic dead weight and volume associated with traditional metal foil current collectors, current FSE fabrication methods suffer from insufficient mechanical stability, electrochemical performance, or industrial adaptability. Here, we demonstrate a scalable camphene-assisted fabrication method that allows simultaneous casting and templating of FSEs comprised of common LIB materials with performance superior to foil-cast counterparts. These porous, lightweight, and robust electrodes simultaneously enable enhanced rate performance by improving mass and ion transport within the percolating conductive carbon pore network and eliminating current collectors for efficient and stable Li+ storage (> 1000 cycle in half-cells) at increased gravimetric and areal energy densities. Compared to conventional foil-cast counterparts, the camphene-derived electrodes exhibit ~1.5x enhanced gravimetric energy density, increased rate capability, and improved capacity retention in coin-cell configurations. A full cell with freestanding anode and cathode cycled for over 250 cycles with greater than 80% capacity retention at an areal capacity of 0.73 mAh/cm2 . This active-material-agnostic electrode fabrication method holds the potential to tailor the morphology of flexible, current-collector-free electrodes to optimize LIBs for high power or high energy density Li+ storage and is applicable to other electrochemical technologies and advanced manufacturing methods

The rapid development of electrochemical energy storage (EES) devices requires multi‐functional materials. Nickel (Ni)‐based materials are regarded as promising candidates for EES devices owing to their unique performance characteristics, low cost, abundance, and environmental friendliness. This review summarizes the scientific advances of Ni‐based materials for rechargeable batteries since 2018, including lithium‐ion/sodium‐ion/potassium‐ion batteries (LIBs/SIBs/PIBs), lithium–sulfur batteries (LSBs), Ni‐based aqueous batteries, and metal–air batteries (MABs). The Ni‐based materials are mainly classified by the various roles of anodes and cathodes for LIBs and SIBs, cathode hosts and separators for LSBs, cathodes for Ni‐based aqueous batteries, and catalysts for MABs, focusing on the relationship between the compositions, structures, and electrochemical performance. Finally, the challenges and prospects of Ni‐based materials for rechargeable batteries are briefly discussed.
