“…Fig. S15 gives the GDC curves of NCM523-Li-Cu cells with PPS-QSSE, which also suggests acceptable rate capability at room temperature, comparing to other solid-state and liquid LMBs works 51,52 , as listed in Table S1 and S2. In addition to rate performance, cycle life (the cycle with 80% of the initial capacity) is also a critical parameter for evaluating LIBs.…”

The urgent need for safe and high energy batteries is pushing the battery studies towards the solid-state direction, and the most central question is finding proper solid-state electrolyte. So far, the recently studied electrolyte systems have obvious advantages and fatal weaknesses, resulting in indecisive plans for industrial production. In this work, we propose a thin and dense lithiated polyphenylene sulfide (PPS)-based solid polymer electrolyte prepared by a solvent-free process in a pilot stage. Moreover, the PPS surface is functionalized to immobilize the anions, increase the Li ion transference number to 0.8-0.9, and widen the electrochemical potential window (>5.1 V). At room temperature, the PPS-based quasi-solid electrolyte (PPS-QSSE) exhibits high intrinsic Li+ diffusion coefficient and ionic conductivity (>10-4 S cm-1), excellent thermal stability, and Li+ transport rectifying effect, resulting in homogenous Li-plating on Cu at high current density. Based on the limited Li-plated Cu anode or anode-free Cu, high loadings cathode and high voltage, the Li metal batteries with PPS-QSSEs deliver high energy density (>1000 Wh L-1) and good cycling at high power (900 W L-1) exceeding that of state-of-the-art Li-ion batteries. The results enlighten the mechanism of solid-liquid two phase conduction and promote the solid-state battery towards practicality.

Summary Vehicle electrification has always been a hot topic and gradually become a major role in the automobile manufacturing industry over the last two decades. This paper presented comprehensive discussions and insightful evaluations of both conventional electric vehicle (EV) batteries (such as lead-acid, nickel-based, lithium-ion batteries, etc.) and the state-of-the-art battery technologies (such as all-solid-state, silicon-based, lithium-sulphur, metal-air batteries, etc.). Battery major component materials, operating characteristics, theoretical models, manufacturing processes, and end-of-life management were thoroughly reviewed. Different from other reviews focusing on theoretical studies, this review emphasized the key aspects of battery technologies, commercial applications, and lifecycle management. Useful battery managing technologies such as health prediction, charging and discharging, as well as thermal runaway prevention were thoroughly discussed. Two novel hexagon radar charts of all-round evaluations of most reigning and potential EV battery technologies were created to predict the development trend of the EV battery technologies. It showed that lithium-ion batteries (3.9 points) would be still the dominant product for the current commercial EV power battery market in a short term. However, some cutting-edge technologies such as an all-solid-state battery (3.55 points) and silicon-based battery (3.3 points) are highly likely to be the next-generation EV onboard batteries with both higher specific power and better safety performance.

“…Moreover, the contact losses among the battery components due to the volume changes of active materials upon cycling is one of the crucial failure mechanisms ( Yao et al, 2019 ; Zhang et al, 2020a ; Popovic et al, 2021 ). Recently, SSE/polymer composites, namely composite electrolytes (CPEs), have emerged as attractive techniques as they combine the advantages of inorganic SSEs (high ionic conductivity and mechanical strength) and solid polymer electrolyte (SPE, good interfacial properties and flexibility) ( Chai et al, 2018 ; Oh et al, 2019 ; Yao et al, 2019 ; Zhang et al, 2020a ; Zhang et al, 2020b ; Fan et al, 2020 ; Chen et al, 2021 ; Popovic et al, 2021 ). Preparation of CPE film relates to slurry-based methodology, which can be easily scaled up.…”

Lithium-rich antiperovskites (LiRAPs) hold great promise to be the choice of solid-state electrolytes (SSEs) owing to their high ionic conductivity, low activation energy, and low cost. However, processing sheet-type solid-state Li metal batteries (SSLiB) with LiRAPs remains challenging due to the lack of robust techniques for battery processing. Herein, we propose a scalable slurry-based procedure to prepare a flexible composite electrolyte (CPE), in which LiRAP (e.g., Li2OHCl0.5Br0.5, LOCB) and nitrile butadiene rubber (NBR) serve as an active filler and as a polymer scaffold, respectively. The low-polar solvent helps to stabilize the LiRAP phase during slurry processing. It is found that the addition of LOCB into the NBR polymer enhances the Li ion conductivity for 2.3 times at 60°C and reduces the activation energy (max. 0.07 eV). The as-prepared LOCB/NBR CPE film exhibits an improved critical current of 0.4 mA cm−2 and can stably cycle for over 1000 h at 0.04 mA cm−2 under 60°C. In the SSLiB with the sheet-type configuration of LiFePO4(LFP)||LOCB/NBR CPE||Li, LFP exhibits a capacity of 137 mAh/g under 60 at 0.1°C. This work delivers an effective strategy for fabrication of LiRAP-based CPE film, advancing the LiRAP-family SSEs toward practical applications.
