Abstract: An MOFs composite electrode material for supercapacitors includes: a Ni-BSC matrix, and a PEDOT coating layer coated on the Ni-BTC matrix, wherein a molar ratio of EDOT to Ni-BTC is 1:(1-4) based on a molar amount of EDOT monomer. A method for preparing the MOFs composite electrode material includes steps of: using nickel nitrate hexahydrate and benzenetricarboxylic acid as raw materials to synthesize Ni-BTC by a hydrothermal method; and using a liquid phase method to grow PEDOT on a surface of the Ni-BTC. An MOFs composite electrode slurry and a working electrode for the supercapacitors including the above MOFs composite electrode material or a MOFs composite electrode material prepared by the above method are also provided. The MOFs composite electrode material provided by the present invention combines advantages of Ni-BTC and PEDOT.
