Abstract:

Herein, the discharge mechanism of lead-acid batteries was discussed and a multiphysics model was proposed to simulate the battery discharge process. The model was tested and verified on the basis of the experimental data of several commercial batteries. The universality of the model was guaranteed by the average empirical parameters of the model. The model was used to analyse the structural parameters of existing batteries, and improvement of the battery structure was proposed on the basis of the simulation results. Herein, a new design scheme was presented for the low-cost fabrication of batteries having reduced volume, lighter weight, and higher capacity. Multiphysics modelling and numerical simulations could greatly reduce the cost and time required for the development of novel batteries.

Key words: lead-acid battery, discharge, physicochemical model, numerical simulation
