Product Description

Harog Technology flow battery graphite bipolar plate


Zhejiang Harog Technology Co., Ltd. is a national-level specialized “new small giant” high-tech enterprise focusing on new energy graphite and related composite materials. It has a standard factory building of 100,000 square meters. The company's leading products are PECVD graphite carrier boats, fuel cell graphite bipolar plates, fuel cell GDL, flow battery graphite bipolar plates, semiconductor graphite, graphene thermal conductive films, etc.


Flow batteries have the characteristics of high safety, high cycle life, and scalability, and are a very promising large-scale energy storage technology.

Flow battery systems include: all-vanadium flow batteries, zinc-bromine flow batteries, iron-chromium flow batteries, sulfur-iron flow batteries, etc. As an important component in a flow battery, bipolar plates are used to realize the series connection and separation of multiple batteries, conduct the current generated in the battery, and provide support for the reaction electrodes in the flow battery.


Harog’s graphite bipolar plates have independent patented technology, and the production process and application effects are at the international leading level. The total production capacity can reach 5 million units/year, and the annual product shipments in 2023 will rank among the best in the industry. It has excellent properties such as high mechanical strength, low permeability, high electrical conductivity, and resistance to strong acid and alkali.
