Cheap, high-rate and long-life batteries are urgently needed for grid-scale storage of renewable energy. Rechargeable zinc (Zn) batteries are potential candidates due to the high volumetric energy density and low cost of Zn anode. However, conventional Zn batteries employing metal oxide cathodes usually suffer from poor rate capabilities caused by the high migration barrier of Zn²⁺ in the metal oxide host structure. Here, we circumvent this dilemma by integrating Zn electrochemistry with bis(trifluoromethanesulfonyl) imide (TFSI⁻) anion (de)intercalation into graphite cathode based on a Zn(TFSI)₂/acetonitrile electrolyte. Owing to the fast intercalation of TFSI⁻ along with the efficient Zn/Zn²⁺ redox kinetics, our Zn/graphite batteries enable an ultrafast charging rate up to 200C (to be fully charged in 18 s) and deliver a high power density of 16.3 kW kg⁻¹, which is comparable to those of supercapacitors. Besides, the rational utilization of the acetonitrile-based electrolyte further endows the resultant battery with dendrite-free Zn deposition, high voltage output (>2.2 V) as well as wide-temperature adaptability from −40 to 80 °C, which is quite promising for grid-scale energy storage. Our work opens a new avenue for building high-rate low-cost batteries through coupling anion intercalation chemistry with multivalent metal anodes.

电网规模的可再生能源存储迫切需要廉价，高速率和长寿命的电池。由于高体积能量密度和低成本的锌阳极，可充电锌（Zn）电池是潜在的候选者。然而，使用金属氧化物阴极的常规Zn电池通常遭受由于Zn ²⁺在金属氧化物主体结构中的高迁移势垒而导致的差的速率能力。在这里，我们通过锌电化学与双（三氟甲烷磺酰）亚胺（TFSI积分规避这个两难^-阴离子（DE）嵌入到基于将Zn（TFSI）石墨阴极）₂ /乙腈电解质。由于TFSI的快速插入^-与高效的锌/锌沿²⁺氧化还原动力学，我们的Zn /石墨电池可实现高达200C的超快充电速率（在18 s内充满电），并提供16.3 kW kg ^-1的高功率密度，这与超级电容器的功率密度相当。此外，乙腈基电解质的合理利用进一步使所得电池具有无枝晶状的Zn沉积，高电压输出（> 2.2 V）以及在−40至80°C的宽温度适应性，这是非常有希望的用于电网规模的储能。通过将阴离子嵌入化学与多价金属阳极耦合，我们的工作为构建高速率低成本电池开辟了一条新途径。
