Conventional stacks
Traditional vanadium battery stacks mainly use ABS, PP, etc. as frame materials; Use epoxy resin board or PVC board as end plate material; To increase the strength, an additional layer of metal sheet is added to the surface. In terms of sealing materials, most companies adopt the traditional sealing ring sealing method.
The light transmittance of each material in the traditional stack is low, and the flow of electrolyte inside the stack cannot be seen. This feature is difficult to achieve intuitive, simple and accurate operation in the quality inspection during stack assembly, maintenance inspection during operation, and troubleshooting in the rework process. However, on the other hand, this design also enhances the secrecy of the stack to a certain extent.
Aggregate debut
In the innovation journey in the field of new energy storage, our company is proud to launch the world's first "visual all-vanadium flow battery stack structure", which not only marks a huge leap in technology, but also serves as the foundation of the core component supplier of flow batteries. Compared with traditional energy storage solutions, our new products provide users with an unprecedented experience with their superior performance and innovative design. As the first in the industry, we are not only leading the technology trend, but also an important step forward in driving the entire industry forward. This achievement is not only the crystallization of the wisdom of our R&D team, but also the embodiment of the spirit of continuous pursuit of excellence and continuous innovation of Zhejiang Polymer.
Visualize the stack
JH001 visual stack adopts transparent frame plate and end plate material, and the corrosion resistance and oxidation resistance of the material have been certified by a third-party professional testing organization, and can operate stably for a long time in a strong acid and alkali solution with high corrosivity and strong oxidation.
The material has high light transmittance, and supports the whole process of visual operation of all-vanadium flow battery production, quality inspection and maintenance inspection.
●Strong acid and alkali run stably for a long time
●Greatly improve the production efficiency of vanadium batteries
●Significantly improve the efficiency of maintenance and inspection during operation
Liquid glue cures and forms seals
JH stack adopts a new type of liquid glue curing molding sealing method, the sealing method is to inject liquid sealant into the corresponding seal during the stack assembly process, and then assemble it into a stack, and the sealant will be automatically cured after a period of time to achieve the sealing effect.
merit
A. The sealant is third-party certified and can operate stably for a long time in a strong acid and alkali solution with high corrosiveness and strong oxidation.
B. The sealant is initially in a gelatinous liquid. During the stack assembly and locking process, the pressure that needs to be applied to the stack is very small, which reduces the pressure on the components inside the stack and greatly reduces the risk of damage to each key component (e.g. separator, plate, etc.) caused by the assembly process.
C. At the same time, because of the smaller pressure, the stack end pressure plate can choose a thinner size, which greatly reduces the weight of the stack.
D. Combined with transparent visualization materials and liquid glue sealing, the internal and external leakage seals of the monolithic battery can be judged to be qualified through clear visual inspection during the assembly process, which greatly improves the efficiency and accuracy of quality inspection.
Finally, the glue sealing technology is adopted, which greatly reduces the sealing area and increases the light transmittance of the stack, which provides great convenience for the maintenance and overhaul during the operation of the stack in the later stage.
