Description

Technical Field

[0001] This utility model belongs to the field of energy storage battery technology, specifically relating to a portable assembled flow battery. Background Technology

[0002] Flow batteries are pollution-free chemical energy storage batteries, characterized by high capacity, recyclability, and long service life. As the popularity of flow batteries continues to grow, more and more research institutions and scholars are joining the field. Unlike corporate product development and manufacturing, universities and research institutions focus more on rapid breakthroughs and new discoveries in flow battery technology, requiring only small experimental batteries rather than large-scale fuel cell stacks for research.

[0003] Currently, the small batteries used by university scholars and research institutions are relatively traditional and simple self-made structures. Although the materials for self-made batteries are relatively easy to obtain, the assembly process takes a lot of time, and it cannot be guaranteed that all self-made parts of small batteries can meet the same size standard. There are many interfering factors, especially the positioning, which is more complicated. In order to make experimental small batteries more readily replaceable and enter into unified standard testing and research, a simple and easier-to-assemble experimental small battery is what research institutions need at present.

[0006] The above technical solution offers the advantage of easy installation. The end plate is used to fix and press the entire small battery in place. The current collector, connected to the end plate, mainly serves as the positive and negative terminals for charging and discharging. The electrode frame contains internal flow channels to improve the reaction efficiency of the small battery. The electrode plates act as conductors and improve the even distribution of electrolyte. The sealing gasket provides a seal to prevent leakage. The membrane provides ion channels for the internal chemical reactions of the small battery. The insertion hole and insertion head are assembled together. Through this assembly method, the electrode frame, current collector, and electrode plate components can be easily and quickly snapped into the end plate to form an integrated assembly.

[0007] Preferably, the end plate, current collector, electrode frame plate, electrode plate and sealing gasket are evenly distributed in pairs and are symmetrical about the membrane.

[0010] The above technical solution can play a fixing role. The groove can fix the electrode plate in the electrode frame plate, thereby protecting and stabilizing the electrode plate.

[0011] Preferably, the inner wall of the electrode frame plate is provided with flow channels.

[0012] The above technical solution can achieve the effect of diversion. The flow channels opened in the electrode frame can guide the flow of electrolyte, thereby achieving the effect of diversion.
