Abstract

Lead-acid batteries are widely used in the automotive industry, and a large amount of waste lead-acid batteries cause enormous pressure on resources and the environment. Repairing aging lead-acid batteries is an effective way to solve this problem. Due to the fact that microwaves can affect most chemical reactions and promote their progress, this paper will study the repair effect of microwaves on lead-acid batteries by combining theory and experiment methods. By analyzing the reaction principle of lead-acid batteries, a multi-physics model is established to study the influence of microwaves on the lead-acid batteries, and an experimental system is built to test the changes in capacity and final charge voltage of lead-acid batteries under the radiation of microwaves. The results demonstrate that microwave treatment significantly enhances the capacity of aging lead-acid batteries, particularly when the initial capacity is slightly above 50% of the rated capacity. Moreover, heating the battery with hot air alone hardly affects its capacity. This study reveals that microwaves have reparative effects on lead-acid batteries, providing a new method for repairing aging batteries.

微波对铅酸蓄电池修复的影响
铅酸蓄电池广泛应用于汽车行业,大量废弃的铅酸蓄电池给资源和环境造成了巨大压力。修复老化的铅酸蓄电池是解决这一问题的有效途径。由于微波能影响大多数化学反应并促进其进展,本文将通过理论与实验相结合的方法研究微波对铅酸蓄电池的修复效果。通过分析铅酸蓄电池的反应原理,建立多物理场模型研究微波对铅酸蓄电池的影响,并建立实验系统测试微波辐射下铅酸蓄电池容量和最终充电电压的变化。结果表明,微波处理能显著提高老化铅酸蓄电池的容量,尤其是当初始容量略高于额定容量的 50%时。此外,仅用热空气加热电池几乎不会影响其容量。这项研究揭示了微波对铅酸蓄电池的修复作用,为修复老化电池提供了一种新方法。
