Description

technical field

[0001] The invention relates to the field of flow batteries, in particular to a double-electron compound flow battery system. Background technique

[0002] In today's world, energy is an important material basis for human survival and development, and an important factor in promoting economic development. With the rapid development of human economy, the consumption of traditional fossil energy is increasing day by day, which has brought serious environmental pollution, so the development of renewable energy has become an indispensable way. However, these renewable energy sources are discontinuous, unstable, restricted by regional environment, and difficult to connect to the grid, resulting in low utilization rate, high wind and light abandonment rate, and waste of resources. Therefore, it is necessary to vigorously develop efficient, cheap, safe and reliable energy storage technology that can be used in conjunction with it.

[0003] Due to the characteristi...
