Characteristics of Ronghe No.1 battery
Ronghe 1 iron-chromium flow battery energy storage technology is known as one of the longest and safest electrochemical energy storage technologies. The electrolyte of this technology is an aqueous solution, which will not explode, and the power and capacity can be flexibly customized according to the needs. It has the advantages of long cycle life, good stability, easy recovery, wide working temperature range and low cost, and meets the needs of large-scale and long-term energy storage in China.
"Ronghe 1" large-capacity battery stack was successfully applied in the demonstration project of 250kW 1.5MWh in Shigou, Zhangjiakou Station, Hebei Province. Up to now, the demonstration project has been running stably for nearly 400 days, completed more than 200 charge and discharge cycles, withstood the extremely cold test of Zhangjiakou at MINUS 40 degrees Celsius, and provided more than 50,000 kWh of clean electricity for the Winter Olympics.
