The high freezing point and poor anode stability of traditional aqueous electrolytes strongly hamper the cyclability and working temperature range of zinc (Zn) metal batteries (ZMBs). Herein, we demonstrate a synergy of low-melting-point (LMP) co-solvents and in-situ gelation treatment by fireproof phosphonitrile derivative facilitates the all-climate operation of reliable ZMBs. As confirmed by theoretical modeling and experimental characterizations, the low-temperature (LT) and high-temperature (HT) tolerances of batteries are realized by the anti-freezing LMP co-solvents and the thermo-stable solid electrolyte interphase (SEI) derived from the residual monomer, respectively. The resulting gel electrolytes not only eliminate safety concerns associated with fire hazards and liquid leakage, but also exhibit a high Zn plating/stripping efficiency of 99.75% over 6,500 cycles with negligible water decomposition and dendrite formation. The as-developed ZMB full cells deliver an extended lifespan in an ultra-wide working temperature range (?70 oC to +80 oC), thereby offering a new avenue for the development of all-climate ZMBs.

基于聚膦腈衍生物的凝胶电解质，用于在 ?70 oC 至 +80 oC 范围内工作的全气候锌金属电池


传统水性电解质的高凝固点和较差的阳极稳定性严重阻碍了锌 （Zn） 金属电池 （ZMB） 的可循环性和工作温度范围。在本文中，我们展示了低熔点 （LMP） 助溶剂和防火膦腈衍生物的原位凝胶化处理的协同作用，有助于可靠 ZMB 的全气候运行。理论建：褪笛楸碚髦な，电池的低温 （LT） 和高温 （HT） 耐受性分别由抗冻结 LMP 助溶剂和来自残留单体的热稳定固体电解质界面 （SEI） 实现。由此产生的凝胶电解质不仅消除了与火灾危险和液体泄漏相关的安全问题，而且在 6,500 次循环中表现出 99.75% 的高镀锌/剥离效率，水分解和枝晶形成可以忽略不计。开发的 ZMB 全电池在超宽工作温度范围（-70 oC 至 +80 oC）内提供更长的使用寿命，从而为全气候 ZMB 的发展提供了一条新途径。
