Abstract: A method for enhancing compressive strength of a lead smelting water-quenched slag-based cementitious material by mechanical activation is provided, belonging to the technical field of solid waste resource treatment. The method includes following steps: grinding and activating water-quenched slag from lead smelting, then mixing with calcium-based solid waste, magnesium-based solid waste, magnesium oxide, portland cement and water, and performing a steam curing and a curing at normal temperature on cementitious material slurry obtained to obtain the lead smelting water-quenched slag-based cementitious material.

Abstract: A flow battery employs a solid suspension charge material to maintain high charge density via stability of a suspension including a binder, conductive carbon and an electrolyte. A cathodic suspension employs carbon powder as a stabilizing agent in a suspension form to avoid precipitation of solids and maintain a high surface area of the suspended solids. The stabilizing agent undergoes agitation and milling to reduce a particle size and increase the change density due to the conductive nature of the fine powdered stabilizing agent exhibiting high energy density. The resulting suspensions are circulated in a charge cell connected to a load for providing electrical power.

Abstract: A nickel/zinc (Ni/Zn) flow battery employs a solid suspension charge material to maintain high charge density via stability of a suspension including a binder, conductive carbon and an electrolyte. Zinc oxide (ZnO) is employed as the anodic (anode) charge material and nickel hydroxide (Ni(OH)2) is employed as the cathodic (cathode) charge material, and form respective anodic and cathodic suspensions using carbon powder and additives to form particles having high stability and high energy density. The resulting suspensions are circulated in a charge cell connected to a load for providing electrical power.
