摘要：
An experimental method for the investigation of the current distribution in the electrodes of lead-acid batteries has been developed. The information is extracted by analysing the heat dissipation in the electrode during the discharge by using a high-performance IR camera. The effect of the current in the metallic grid can be de-convoluted from the total heat produced in the electrode by numerical processing of the temperature distribution over the electrode surface. By its simplicity and effectiveness, the proposed method has the potential to become an important tool in optimising electrode geometry.
