Description

A Novel Titanium Manganese Single Flow Battery technical field The invention belongs to the battery field, be specifically related to a kind of novel titanium manganese single liquid flow battery. Background technique With the development of the economy, the demand for energy is increasing day by day, and the environmental problems caused by the large consumption of fossil energy issues are becoming increasingly prominent. Large-scale utilization of renewable energy and energy diversification have become energy security and sustainable development in all countries in the world. important strategy for development. However, the discontinuity and instability of renewable energy such as wind energy and solar energy make their direct use Therefore, the use of energy storage technology to achieve continuous supply of renewable energy has become the key to solving the above problems. flow battery Due to the flexible design (separate design of energy and power), good safe...

Problems solved by technology

[0004] As a low-cost, environmentally friendly new type of flow battery, titanium-manganese flow battery has gradually attracted the attention of researchers, but the disproportionation reaction of trivalent manganese ions at the positive electrode generates MnO 2 Deposits are likely to cause positive electrode blockage and stack damage. Generally, the generation of MnO is avoided by controlling the concentration of trivalent manganese ions. 2 deposits, but it is difficult to completely avoid the occurrence of failures, and can only use the single-electron transfer reaction from divalent manganese ions to trivalent manganese ions, which seriously hinders the development of titanium-manganese flow batteries
