Peak Summary: This product has five major features:

1. The electrolyte delivery and distribution system is separated from the capacity box or power box, truly realizing the decoupling configuration of energy and power. The standardized pipeline system is conducive to engineering installation, operation and maintenance, and environmental heat dissipation;

2. High voltage stack technology has achieved the transformation of power boxes from low voltage high current to high voltage low current, providing three optional topology structures: battery series parallel, DC isolation cascade, and single-phase AC cascade. The power of a 20 foot power box has jumped from the current 500-800kW to 2MW, and the voltage has jumped from 300-500V to 3000-4000V;

3. Based on the independence of the capacity box and pipeline system from the power box, the energy storage power station has achieved online SOC regulation within the station while participating in power market dispatch, significantly reducing power market capacity configuration and thus lowering initial installation costs (the duration of an independent frequency regulation power station is one-quarter of that of a lithium battery energy storage power station);

4. High voltage stack technology based on power box size (350-500A, 240-350V) lays the foundation for the development of high-power density power boxes, MOSFET multi module cascade, IGBT multi stack cascade technology, and leaves room for the development of 3MW energy storage modules based on material technology progress;

5. Station level power allocation and energy consumption optimization technology for energy and power dual electricity markets, achieving graded energy consumption optimization under environmental constraints for cold standby, hot standby, rated and non rated operating conditions.

With the rapid development of new energy such as wind power and photovoltaics, the volatility and intermittency of new energy generation are the main challenges facing their future high proportion application. Energy storage, as a key supporting technology to improve grid reliability and promote the consumption of new energy, has attracted much attention.

Flow battery technology, especially vanadium redox flow battery (VRFB), is considered one of the most promising large-scale energy storage technologies due to its high safety, high efficiency, long cycle life, modular design scalability, and flexibility. However, the current cost of flow batteries is still relatively high, and improving battery power density and operating efficiency is one of the effective ways to reduce the cost of flow batteries.

As one of the key materials of flow batteries, electrodes provide reaction sites for redox reactions during charging and discharging processes, and provide channels for the transport of internal active substances. The performance of electrode materials directly affects the electrochemical reaction rate, battery internal resistance, and electrolyte transport process. Therefore, structural design and surface property modification of electrode materials are of great significance for improving the power density, operating efficiency, and service life of batteries, and reducing system costs.
