CGC

Energy Storage

The research of CGC Energy Storage Technology began in 2007. Over the past decade, along with the development of energy storage technology, it has carried out technical research on different forms of energy storage, including lead-acid batteries, colloidal batteries, lithium-ion batteries, flow batteries, supercapacitors, superconductors, flywheels, compressed air, molten salts, and hydrogen. This covers different types of energy storage technologies such as electrochemical, electromagnetic, mechanical, thermal, and chemical. It provides customers with technical services for the whole industrial chain, full lifecycle, and all processes from raw materials to power station operation, including standardization, testing, inspection, certification, technical due diligence, and technical evaluation.

CGC participates in the formulation of energy storage standards and carries out extensive cooperation with leading domestic and international technical institutions. It provides convenient, fast, and industry-leading technical services to enterprises. Its technical capabilities and test certification results have been widely recognized by customers and financial insurance institutions.
