Abstract

The invention provides a water-soluble fast reaction kinetics couple-based photoelectrochemical energy storage battery. When the battery is charged, in-situ transformation of light energy into chemical energy is achieved by using photoelectrochemical reaction driven by self-bias of narrow band gap photoelectrodes and the chemical energy is stored into an active material of a battery electrolyte; and when the battery is discharged, electrochemical reaction is carried out, thereby achieving transformation of the chemical energy into electric energy. The photoelectrochemical energy storage battery integrates a photoelectrochemical battery and a flow battery; the disadvantage that a solar cell cannot achieve electric energy storage is overcome; meanwhile, a single charging mode of the energy storage battery is also expanded; and solar energy in-situ transformation, storage and controllable utilization without assistance of external bias are achieved. Water-soluble fast reaction kinetics redox couples are adopted as the active material; the utilization rate of photo-induced carriers on the surfaces of photoelectrodes is close to 100%; meanwhile, the discharge power density of the battery can reach 0.5W / cm<2>; large-scale amplification can be achieved; and the photoelectrochemical energy storage battery is suitable for different scales of solar energy-energy storage-power generation processes.

Description

technical field

[0001] The invention relates to a photoelectrochemical energy storage battery based on a water-soluble fast reaction kinetics redox pair, more specifically, a photoelectrochemical energy storage battery that couples a photoelectrochemical battery with a flow battery, and belongs to the photoelectrochemical energy storage battery. The intersection of batteries and flow batteries. Background technique

[0002] In the traditional photovoltaic power generation system, the solar cell is equivalent to a light energy converter, which only involves energy conversion, cannot realize the storage of electric energy, and cannot output energy when there is no sunlight. At present, the photovoltaic power generation system realizes the storage of electric energy by attaching a secondary battery to the outside of the solar cell. The system is mainly composed of photovoltaic arrays, controllers, secondary battery packs, inverters and other equipment. However, the system invo...
