We developed a one-pot strategy to fabricate activated carbons by using water soluble phenol-formaldehyde resin as precursor and Na2CO3 as activating agent. The prepared carbon materials have a typical hierarchical pore texture and a large specific surface area (SSA) of 1357m2g−1. When used as electrode materials for supercapacitors, the material shows a high specific capacitance of 226Fg−1 at 0.05Ag...
By using both lead-doped porous carbon composite and graphite, a hybrid carbon additive was designed to inhibit irreversible sulfation so as to enhance the cycle performance of lead-carbon battery anodes. The synergistic action mechanism was studied. We show that the hybrid carbon additive presents a unique structure of sheets attached to porous bulk, and this structure could confine the lead particles...
