“…This peak corresponds to the contact resistance at current collectors and electrode interfaces, and electrode particles. [42,43] The D2 and D3 peaks are associated with ion transport across the anode and cathode interface, respectively. [44] The D4 peak with the largest time constants (frequency below 0.1 Hz) is related to the solidstate diffusion (charge transfer process) of the Se cathode.…”

Solid‐state Li–S and Li–Se batteries are promising devices that can address the safety and electrochemical stability issues that arise from liquid‐based systems. However, solid‐state Li–Se/S batteries usually present poor cycling stability due to the high resistance interfaces and decomposition of solid electrolytes caused by their narrow electrochemical stability windows. Here, an integrated solid‐state Li–Se battery based on a halide Li3HoCl6 solid electrolyte with high ionic conductivity is presented. The intrinsic wide electrochemical stability window of the Li3HoCl6 and its stability toward Se and the lithiated species effectively inhibit degeneration of the electrolyte and the Se cathode by suppressing side reactions. The inherent thermodynamic mechanism of the lithiation/delithiation process of the Se cathode in solid is also revealed and confirmed by theoretical calculations. The battery achieves a reversible capacity of 402 mAh g−1 after 750 cycles. The electrochemical performance, thermodynamic lithiation/delithiation mechanism, and stability of metal‐halide‐based Li–Se batteries confer theoretical study and practical applicability that extends to other energy‐storage systems.

“…The R SEI and R B for the NMC811 cells, as summarized in Figure 2c and Figure 2e, closely follow the capacity fade trend observed in Figure 2a, commensurate to more SEI growth and electrolyte decomposition at the anode (see Figure S5 in the Supporting Information for additional explanation). [ 12,15,19,39,40 ] The NMC811 aging issues captured through the R CEI+CT impedance in Figure 2d, [ 41,42 ] as obtained from the mid‐frequency depressed semi‐circle in Figure S4 in the Supporting Information, show a gradual increase with cycling for 1C to 9C and 4.1 V charging conditions. This gradual and less severe increase in R CEI+CT in Figure 2d is starkly different from the NMC532 cells that showed sped up cathode degradation after about 400 cycles for the same fast‐charge cycling conditions, as shown in Figure 2 in ref.…”

As the battery industry shifts toward high Ni content cathodes, such as LiNi0.8Mn0.1Co0.1O2 [NMC811], a complete understanding of the degradation mechanisms of NMC811 under extreme fast charging (XFC) (XFC, ≤10–15 min charging) conditions is needed. Such comprehensive understanding would identify the most critical materials gaps that need to be addressed for enabling XFC long‐life cells for electric vehicles. This study maps out the key aging mechanisms for NMC811 cycled at different XFC conditions (between 1C and 9C) for up to 1000 cycles. To acquire a fundamental understanding of utilization and degradation, cells are evaluated using a range of electrochemical techniques, and multimodal and multiscale microscopy techniques to quantify chemical, structural, and crystallographic degradation as a function of cycling conditions for the NMC cathode. When comparing NMC811 to NMC532, it is observed that NMC811 has a greater subsurface crystallographic degradation and displays a similar magnitude of subparticle cracking. However, the NMC811 maintains superior performance despite those advanced degradations. The superior cycle life performance is attributed to the NMC811 particles having radially oriented grains and improved transport properties. NMC811 shows between 4.6× and 3.15× reduction in capacity fade than NMC532 for charging rates between 4C (e.g., 15‐min charging) and 6C (10‐min charging).

“…Besides these electrode-related overpotentials, mass transport in the electrolyte and EEI must be considered. [23] Improving the conductivity of electrolyte is one of the key factors to improve the fast-charging capability of LIBs. [24] Moreover, the compatibility of electrolyte with the active materials is also important because electrolyte decomposition occurs on both anodes and cathodes, [25] leading to the formation of SEI/CEI.…”

Rapid development of high-energy-density lithium-ion batteries (LIBs) enables the sufficient driving range of electric vehicles (EVs). However, the slow charging speed restricts the popularization of EVs. Commitment to fast-charging research is considered to be the key to advance the EVs strategy. This Review discusses the kinetic factors limiting the fast-charging capability at the material aspects, and summarizes the recent research strategies to achieve fast-charging performance of high-energy-density LIBs through electrode engineering, electrolyte design, and interface optimization. The increasingly important role of computational tools and advanced characterization techniques in fundamentally understanding the failure mechanism of LIBs is emphasized, and the analysis of the thermal runaway problem in the fast-charging process and the corresponding thermal optimization scheme is also involved to give the guidance for the more rational battery design. In view of these factors and strategies, some future perspectives for realizing high-performance fast-charging LIBs are proposed, which are expected to facilitate the large-scale application of fast-charging LIBs in EVs.
