High Performance and High Cycle-life Lead-Acid Batteries with Carbon-based Electrodes


  • To reduce lead-acid batteries’ sulfation problem and enhance its cycle life through addition of graphene into electrodes.
  • To explore the fundamental electrochemical mechanism of the interface between graphene and active material, as well as its impact on the battery performance.



  • Incorporate graphene into lead-acid battery electrodes in the form of additive and/or 3D current collector in controlling the graphene conductive network
  • Functionalize chemical derivative graphene oxide with controlled reduction degree as carbon additive for testing of electrochemical activity
  • Investigate fundamental electrochemical mechanism of the interface through experiments and molecular dynamic model



  • Enhance lead-acid batteries partial state of charge (PSoC) cycle life by more than 100% compared to commercial batteries
  • Identify key factors governing the interfacial transformation of PbSO4
  • Evaluate the impact of interfacial coupling on the battery performance
