Finding a new battery chemistry is of urgent importance to reply diverse deployment trends of battery-driven devices. Here we propose a strategy to configure dual-ion storage battery based on SO₂ solvated chloroaluminate molten salt complex electrolyte employing Cu₂O cathode material. The proposed battery chemistry is proven by two different couples of dual-ion (Li/Cl and Na/Cl) batteries that show about 590 Wh kg⁻¹ based on Cu₂O mass with working voltage of 3.4 V as well as highly stable cycle performance up to 300 cycles. Further improvement may be possible by optimizing the electrode material with the compatible electrolyte composition, thus being another alternative to address various requirements of next-generation battery for future applications.

寻找新的电池化学物质对于应对电池驱动设备的各种部署趋势至关重要。在这里，我们提出一种基于SO ₂溶剂化氯铝酸盐熔融盐复合电解质（采用Cu ₂ O阴极材料）配置双离子蓄电池的策略。通过两对不同的双离子（Li / Cl和Na / Cl）电池对所提出的电池化学性质进行了证明，基于Cu ₂，它们显示出约590 Wh kg ^-1质量为3.4 V的工作电压，具有高达300个循环的高度稳定的循环性能。通过用相容的电解质组成优化电极材料，可能会进一步改进，从而成为满足下一代电池各种要求的另一种选择，以适应未来的应用。
