Conductive ceramic, method for preparing same and application for same

Abstract

The invention discloses a conductive ceramic, a method for preparing the same and an application for the same. The conductive ceramic comprises a conductive agent, a ceramic composite material and a dielectric material, wherein the conductive ceramic contains, in parts by weight, 5-20 parts of conductive agent, 55-70 parts of ceramic composite material and 5-15 parts of dielectric material. The conductive ceramic is used for loading an acidic carrier, as well as has very strong adsorption force and corrosion resistance on active substances and strong electrolyte; and the electric conductivity of the conductive ceramic is the double of that of pure metallic titanium and two orders of magnitude higher than that of graphite. The conductive ceramic grid prepared from the material is used for replacing traditional lead-based grid, and only the good characteristics and mature process of 'single-substance bipolar salinization' for the active substances of traditional lead battery are kept, so that the parameters of specific energy, charge-discharge time, deep cycle life, cost / effectiveness ratio and the like of whole battery are superior to those of nickel metal hydride battery.

Description

technical field [0001] The invention relates to the field of ceramics, in particular to a conductive ceramic, a method for preparing the ceramic and an application of the ceramic. Background technique [0002] Any electric propulsion system device hopes that the selected battery has large capacity, light weight, small size, high power density, long life, low cost / efficiency ratio, short charging time, good charge and discharge resistance, convenient maintenance, and safe use. The performances of various storage batteries that have been used or tried in electric vehicles are still not up to the requirements of the developing energy storage and electric propulsion system for storage batteries. The performance schedule of various batteries is as follows: [0003] [0004] The above data are quoted from the book "Power Battery" edited by Gui Changqing and others published by Machinery Press in 2009. [0005] Based on the above data, relatively speaking, although the specifi...

AI Technical Summary

Problems solved by technology

The comprehensive performance of the sealed maintenance-free, valve-controlled, tubular, and wound bipolar batteries that have been on the market can be said to have been tapped to the limit, and the main reason for the low specific energy is that the reaction efficiency of the active material is less than 50% and the mass is only 40%, another HSO 4 - The ions are restricted by the thickness and material of the plate, and the grid and other non-current-carrying substances account for nearly 40%. The relationship between the active material, the quality of the grid, and the density of the electrolyte is extremely unreasonable. The source of the design is to solve the specific mass, specific volume, α, γ coefficient ratio, and it is difficult for lead-based batteries to make breakthroughs
