Abstract Due to the availability of zinc resources, and reduced security risks, aqueous zinc‐ion batteries (AZIBs) are potential contenders for next‐generation energy storage systems. With multi‐scene application AZIBs, temperature adaptation electrolytes poses a great challenge. However, electrolyte is prone freezing in sub‐zero environments, which leads undesirable problems such as ion transfer poor electrode/electrolyte interface, resulting sharp deterioration electrochemical properties AZIBs cold conditions limited practical use AZIBs. Antifreeze modification strategies have gained popularity effective ways optimise low‐temperature behaviour AZIB. The results recent studies systematically summarised focusing on methods, principles, effects achieved. Firstly, authors describe mechanism failure at low temperatures. Subsequently, antifreeze summarised, including utilisation high salt content, design organic electrolytes, adoption additives, building hydrogel electrolytes. Finally, issues faced by temperatures further indicated suggestions provided their future development.

Abstract Lithium iron phosphate (LiFePO 4 ) batteries are increasingly adopted in grid‐scale energy storage due to their superior performance and cost metrics. However, as the desired power further densified, lifespan of LiFePO is significantly limited, mainly because lithium plating severely occurs on graphite anode. Here, first characteristics both energy‐type power‐type electrodes single‐layer design deciphered. Based these findings, a suitable two‐layer with top layer one bottom layer, disclosed. Such configuration effectively inhibits throughout electrode, drastically increasing an energy‐ power‐densified battery. The assembled pouch cell density 161.5 Wh kg −1 , delivers capacity retention rate 90.8% after 2000 cycles at 2 C. This work provides valuable insights into failure mechanism electrodes, but also innovative strategies electrode engineering for extending batteries’ horizon.

Lithium‐ion batteries (LIBs), widely used in electric vehicles (EVs) and other applications, are increasingly expected to deliver higher energy densities stable performance over a wide temperature range, posing stringent challenges for advanced electrolyte design. However, achieving these properties remains challenging with currently commercialized ethylene carbonate (EC)‐based electrolytes. Herein, propylene (PC)‐based system is reported, employing hexafluorobenzene (HFB) fluoroethylene (FEC) as synergistic additives. Specifically, HFB facilitates compatibility graphite anodes through selective interfacial adsorption, while the decomposition of FEC stabilizes solid interphase (SEI), mitigating formation high‐impedance interfaces. This tailored exhibits superior ionic conductivity, excellent oxidative stability, broad tolerance. When validated at 4.5 V, high‐loading NCM811/graphite cells achieve nearly full capacity 100 cycles low temperatures (−20 °C), pouch retaining 80% their after 470 cycles. These findings underscore effectiveness strategic additive engineering advancing development PC‐based electrolytes practical LIBs.

The performance degradation of sodium-ion batteries (SIBs) in extremely low-temperature conditions has faced significant challenges for energy storage applications extreme environments. This review systematically establishes failure mechanisms that govern the SIBs, including significantly increased electrolyte viscosity, lattice distortion and adverse phase transitions electrodes, sluggish desolvation kinetics at solid interface. Herein, we specifically summarize a series multi-scale optimization strategies to address these challenges: (1) optimizing low-freezing-point solvent components regulating solvation structures increase ionic diffusion conductivity; (2) enhancing hierarchical structure electrodes electron distribution density improve structural stability capacity retention low temperatures; (3) constructing an inorganic-rich interphase induce uniform ion deposition, reduce barrier, inhibit side reactions. provides comprehensive overview SIB coupled with advanced characterization first-principles simulations. Furthermore, highlight solvation-shell dynamics, charge transfer kinetics, metastable-phase evolution atomic scale, along critical pathways overcoming limitations. aims establish fundamental principles technological guidelines deploying SIBs
