AI Technical Summary
Existing zinc-silver backup batteries struggle to achieve efficient electrolyte mixing and stable electrochemical performance in a wide temperature range. External heating and mechanical reinforcement devices reduce energy density and fail to address the issues of low-temperature activation hysteresis and high-temperature corrosion-induced hydrogen evolution.
Dimethyl sulfoxide (DMSO) is used as a functional additive, combined with a special stirring method, to prepare a composite electrolyte. The stirring component and temperature control component ensure the precise mixing of the additive and the base electrolyte, forming a physical isolation layer to improve fluidity and prevent corrosion.
Without relying on external heating or mechanical reinforcement devices, the zinc-silver reserve battery achieves rapid activation and efficient discharge over a wide temperature range, improving the battery's low-temperature fluidity and high-temperature safety, and meeting the requirements for equipment miniaturization and lightweighting.
