Research on the Mechanism of Activated Carbon in the Performance Improvement of Lead-Carbon Batteries
In order to realize the transformation of the industry to green and low-carbon,China actively promotes the adjustment of energy structure and vigorously develops renewable energy,therefore,the construction of energy infrastructure such as electrochemical energy storage has become the key technical point to be broken through.This paper focuses on the application of carbon-based materials represented by activated carbon in lead-carbon batteries and their performance improvement,and clarifies the mechanisms of their capacitive effects,steric in-drances,increased conductivity and electrochemical catalysis.The capacitive effect contributes significantly to the improvement of the charge-discharge efficiency of the lead-carbon battery at high-rate partial state of charge,and the other three effects have synergistic benefits in alleviating the irreversible sulfation of the negative elec-trode,which indirectly improves the cycle life of the battery.This paper aims to provide a scientific basis for the application of carbon-based materials in the field of lead-carbon batteries and their performance improvement.
