Technological Breakthrough – Another Industry Award Won

In the selection of innovative products, the sealing and welding of single cells in flow batteries independently developed by UW Laser stood out from numerous candidates and once again won the "2025 Laser Processing Industry-Ringier Industry Innovation Award". This achievement stems from the technological breakthrough of applying laser welding as a sealing method for flow batteries. Mr. Ma Jiajun, Manager of the Flow Battery Industry Department of General Automation Division, represented the company at the conference and received the award on stage.

As a widely recognized authoritative award in the industry, the Ringier Technology Innovation Awards has always adhered to the principles of fairness and objectivity, committed to honoring products and technologies with significant innovative value. This is the second time UW Laser has won this honor since 2021, highlighting the industry's high recognition of its technological strength and leading position in intelligent manufacturing solutions for flow energy storage equipment. It also demonstrates UW Laser’s firm commitment to promoting the development of green energy.

Breaking Through Bottlenecks: Reconstructing Flow Battery Manufacturing Processes

A flow battery stack is assembled by stacking multiple single cells. The main components of a single cell include bipolar plates, electrode frames, electrodes, and membranes. Currently, the mainstream sealing methods for flow battery stacks in the industry include hot-melt sealing, dispensing, fluororubber cord sealing, and face sealing. These methods not only have high requirements for raw materials and high process costs but also suffer from unstable reliability. As the sealing adhesive is prone to aging, the risk of leakage increases, which seriously affects the battery's service life.

As a leader in China's laser welding field, UW Laser relies on 20 years of process technology accumulation in the vertical laser welding sector. By independently developing laser welding as a sealing method for flow batteries, it has solved the hidden problems caused by traditional methods. After plastic laser welding, the sealing performance is equivalent to (or greater than) that of the base material, providing a brand-new technical route for industry applications.

Compared with traditional sealing methods, laser welding has the following advantages:

1. It can achieve high-strength sealing effect, effectively preventing liquid leakage and ensuring durability and reliability. 

2. It can achieve high-precision welding, showing good adaptability to the sealing of complex-shaped and small-size components. 

3. Compared with traditional welding, laser welding has a smaller heat-affected zone, which can reduce thermal damage to surrounding materials.

4. Laser welding is easy to realize automatic control and mass production, improving production efficiency and quality stability.

5. For applications involving certain special materials or with special requirements for sealing materials, laser welding may have more advantages.

As the "dual-carbon" objectives accelerate, the long-duration energy storage market is experiencing explosive growth. Flow batteries, a highly promising technology in this field, have achieved a critical breakthrough in green manufacturing through the innovative application of laser welding. This technology not only enhances production efficiency but also promotes the industry’s transformation toward sustainability by eliminating chemical pollution risks associated with traditional processes. With deepening technological innovation and industrial collaboration, the large-scale deployment of flow batteries is accelerating.

Collaborative Innovation: Shaping a Green Energy Storage Ecosystem Together

Taking this award as a new starting point, UW Laser will continue to deepen the innovative application of laser welding technology in the green energy sector. The company will further strengthen collaborative R&D with upstream and downstream industry partners, promoting the deep integration of laser welding processes in scenarios such as flow battery stack integration and full-industry-chain automated production. Through more efficient and reliable intelligent manufacturing solutions, UW Laser aims to help flow batteries break through the cost and technical bottlenecks of large-scale application.

In the future, UW Laser is committed to joining global partners in driving technological innovation as the engine and green manufacturing as the foundation. Together, we will build a safe, efficient, and sustainable new energy storage industry ecosystem, contributing more Chinese wisdom and solutions to global energy transition and sustainable development.
