The full vanadium redox flow battery has reached the turning point of industrialization, let's see how Hualu Group seizes the new track

2025-12-02

Recently, the vanadium redox flow battery field has been filled with good news - the electrolyte formula has been continuously optimized, the power density the stack has been significantly improved, and large-scale energy storage projects in many provinces and cities have been put into operation one after another. As a group that has been deeply cultiv in this field for a long time, we keenly feel that the industry is transitioning from the "technological verification period" to the "large-scale commercial period".

This turning point is not accidental, but the result of the combined effect of technological accumulation, policy-driven, and market demand. For Huasu Group, this is only an unprecedented opportunity, but also a key period for transformation and upgrading.

Achieve a leap in core technology

In the past year, the core technology of all-vanadium flow battery has achieved a leap-forward improvement. The stack design has been continuously optimized and the maturity of laser welding process has reduced the cost of the stack while significantly improving the consistency and reliability of the product. This has put forward new requirements for the upgrading of Huong Group's production line and has also brought a realistic path to reduce costs and increase efficiency.

In the field of core materials, the innovation of gradient pore graded porous electrode means that the same size of battery can output more power, significantly enhancing the market competitiveness of the product.

Historic breakthrough in high temperature problem

The stability of the electrolyte has always been a key factor limiting the widespread application of all-vanadium flow batteries. The research results reveal the precipitation of pentavalent vanadium ions and develop an electrolyte formula that can operate stably.

This breakthrough greatly expands the application scenarios of all-vanadium flow batteries Huasu Group has begun to connect with relevant technical teams to jointly promote the application of this achievement in product terminals, and it is expected that a high-temperature resistant battery will be launched next year.

For customers, this means that in hot summer or high-temperature industrial environments, the battery system can still maintain stable output without the need expensive auxiliary cooling systems, and the cost per kilowatt-hour throughout the lifecycle will be further reduced.

Diversification enhances application scenarios

From large-scale power generation side storage to urban centers and gas stations, the application boundary of all-vanadium flow batteries is expanding. The 12kW/500kWh station-level energy storage system put into operation by Sinopec in Tianjin has proven its unique value in safety-sensitive scenarios.

The attribute of "essentially safe" is becoming the core competitiveness of Huasheng Group to expand the user-side market. Compared with lithium batteries the non-flammable and non-explosive characteristics of vanadium redox flow batteries make it easier to pass through strict safety approvals, especially suitable for energy storage in densely populated areas.

Meanwhile, the construction of the 50MW/200MWh all-vanadium redox flow energy storage station inyang, Hubei, marks the start of the large-scale long-duration energy storage market. This type of project puts forward higher requirements for the system integration ability and capital of enterprises, and is reshaping the industry competition pattern.

Promote the integration of industry and research in all aspects

The in-depth advancement of industry-academia-research integration is changing the innovation model of the full vanadium redox flow battery industry. material research and development to system integration, the close cooperation of various links in the industry chain has greatly accelerated the speed of technological innovation and transformation.

The joint laboratories established Huashen Group with multiple scientific research institutions, this deeply bound cooperation model allows us to transform laboratory breakthroughs into product advantages in the first time. On the other hand, the integration of the industry chain is becoming the standard configuration of leading enterprises. From vanadium material supply to stack manufacturing, and then to system integration, enterprises with full-chain layout show advantages in cost control and supply chain stability.

About us

Sichuan Hualuguangdian Group Co., Ltd. was established in 2018, headquartered in the Nax District of Luzhou City, Sichuan Province, and is a practitioner of the national "double carbon" strategy and a leading enterprise in the new energy field. The company takes " manufacturing of photovoltaic storage energy services" as its core strategy, building a full-industry-chain layout covering photovoltaic EPC, van redox flow battery system manufacturing, and green power technology research and development. The company owns more than 30 core patents and international authoritative certifications (CE/CB/F/ROHS, etc.).

Relying on the Chinese Academy of Sciences technology system, and in conjunction with institutions such as Sichuan Chemical Institute and Light University, the company has built a vanadium-battery energy storage research laboratory, overcome the technical barriers of all-vanadium redox flow batteries, achieved breakthroughs in longtime storage of more than 72 hours, a cycle life of more than 20,000 times, and a system efficiency of more than 85% and filled the industry's smart manufacturing blank. As a core member of the ecological circle of several energy state-owned and central enterprises, the group has in-depth cooperation with enterprises such as Huawei, Longi, Huanwang, and Sunshine, serving multiple central enterprise large projects, creating a "device platform service" energy Internet ecology of, solar, and storage, and providing strong technical support for the construction of a new power system in the country.

In 2026, the company plans to an equipment manufacturing base for new energy in southern Sichuan, further promoting the restructuring of the global energy system. With the advantage of technological innovation and full-industry-chain, Huarong Photoelectric has become a new energy technology group with growth potential in the western part of China, injecting strong power into the global energy transformation, and helping to the "double carbon" goal.

Three forces—technological breakthroughs, expanded applications, and industrial synergy—are coalescing into a powerful impetus, propelling the vanadiumox flow battery industry onto the fast lane of development. The industry will witness a historic transition from "demonstration projects" to "large-scale applications" in the next three five years.

In the face of this significant opportunity, Huasu Group is fully prepared. Through the dual-engine of technological innovation and industrial layout, it aims secure a place in the global energy storage market.
