Preparation of a Hierarchically Porous Lead/Carbon Composite and Its Application in Lead‐Carbon Batteries

Preparation of a Hierarchically Porous Lead/Carbon Composite and Its Application in Lead‐Carbon... A novel and scalable lead‐modified phenolic resin‐based carbon material (Pb/PRC) has been successfully prepared by using lead‐modified phenolic resin (Pb/PR) as a precursor, toluene as a pore‐forming agent, and KOH as an activating agent. The Pb/PRC composite presents a hierarchically porous nanosphere structure, and this structure contributes to prolong its cycling life under high‐rate partial state‐of‐charge (HRPSoC) operation. Pb/PRC with nano‐lead can effectively inhibit hydrogen evolution and provide pseudocapacitance. Compared with a blank negative plate, a lead‐carbon battery with Pb/PRC displays 18 000 cycles under HRPSoC operation and exhibits a capacity of 100 mA h g−1 at 2 C discharge rate. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png ChemPlusChem Wiley

Abstract

A novel and scalable lead‐modified phenolic resin‐based carbon material (Pb/PRC) has been successfully prepared by using lead‐modified phenolic resin (Pb/PR) as a precursor, toluene as a pore‐forming agent, and KOH as an activating agent. The Pb/PRC composite presents a hierarchically porous nanosphere structure, and this structure contributes to prolong its cycling life under high‐rate partial state‐of‐charge (HRPSoC) operation. Pb/PRC with nano‐lead can effectively inhibit hydrogen evolution and provide pseudocapacitance. Compared with a blank negative plate, a lead‐carbon battery with Pb/PRC displays 18 000 cycles under HRPSoC operation and exhibits a capacity of 100 mA h g−1 at 2 C discharge rate.
