The　carbon-based　lead　foam　was　produced　by　electrodepositing　a　uniform　and　dense　lead　coating　on　lightweight　carbon　foam　in　fluoborate　system　under　appropriate　conditions.　The　cyclic　voltammetry　showed　that　its　electrochemical　properties　resembled　the　metallic　pure　lead.　A　lead　acid　battery　equipped　with　the　carbon-based　lead　foam　as　positive　current　collector　undergone　a　charge-discharge　test.　The　battery　had　a　high　discharge　capacity　and　a　good　cycling　stability,　which　indicated　that　the　carbon-based　lead　foam　could　serve　as　positive　current　collector.　The　three-dimensional　net　structure　of　carbon-based　lead　foam　provides　larger　surface　area　than　traditional　lead　alloy　grids,　thus　enhances　the　specific　capacity　of　lead　acid　battery.　The　carbon-based　lead　foam　might　be　a　promising　substitute　for　lead　alloy　grids.
