Abstract

The invention discloses an iron-chromium flow battery. The iron-chromium flow battery comprises positive electrodes, negative electrodes, diaphragms, current collecting end plates and electrolyte solutions, wherein each positive electrode and the corresponding negative electrode are located on the left and right sides of each diaphragm; the positive electrodes, the negative electrodes and the diaphragms are located between the current collecting end plates at left and right ends; the electrolyte solutions are located in positive electrode cavities and negative electrode cavities; and at leastone of positive electrode and negative electrode materials is mainly made of a carbon paper material prepared from graphite fiber. The electrode materials are mainly made of the carbon paper materialprepared from the graphite fiber, and the performance and the capability of the iron-chromium flow battery are improved.

Description

technical field [0001] The invention relates to the field of new energy, in particular to an iron-chromium flow battery. Background technique [0002] As early as the 1970s and 1980s, the Lewis Research Center of NASA (Lewis Research Center) invested a lot of research on the iron-chromium (Fe / Cr) battery system, overcoming the electrolyte solution of the positive and negative electrodes. Through the mixing problem of the electrolyte membrane and the preparation of the key components of the catalytic electrode, a 1kW battery energy storage system has been developed, and the efficiency of the battery is still above 80% after 100 charge-discharge cycles. Afterwards, the technology property rights were transferred to commercial companies to prepare for product development, but due to the slowdown of the oil crisis, the company did not choose to further develop this technology. In the late 1980s, Japan's Sumitomo Corporation Shimokansai Electric Power Company reported that a 10k...
