Energy StorageYou want to improve your throughput because the demand for energy storage is massive — we can help with that. Get Started
We build the automation equipment that produces energy storage parts — like flow batteries.
Looking to partner with an equipment supplier that can help you improve throughput to ramp up the production of your energy storage products? Our plastic welding technologies and custom automation expertise help you make parts faster and better. Our engineers will help you at every step — from design and prototyping to validation and production.
Technologies that help you manufacture batteries
Hot plate welding is a process that is used for welding two plastic parts together. This process is beneficial for manufacturing flow batteries for the energy storage market because it creates strong hermetically sealed welds.
When manufacturing flow batteries, you need to be able to weld several layers of components on top of each other. That’s where stack welding comes in. Stack welding is hot plate welding multiple layers of parts together. Extol’s servo-driven hot plate welders are perfect for this task. To start, the machine welds the first two layers together. Then, you or a robot loads the next layer on top of the two welded layers. The welding machine measures the height of the stack, reprograms itself, and welds the new layer to the stack. This process is repeated over and over again to make stacks that are 10, 20, and even 40+ layers.
Heat sealing is another important technology used for manufacturing flow batteries. This technique is used for welding thin parts to plastic. It works by using heat to melt the plastic, and then pressing it together so that it fuses.
Some components in a flow battery system need to be welded very cleanly and precisely. Laser welding is a good option because it uses an extremely accurate infrared laser to create welds without any particulate. Laser-welded parts are also very strong and durable, making them perfect for use in flow battery systems.
Validate your high-quality parts.
Extol can help with validating flow battery parts. We have services like burst testing, leak testing, and tensile testing to ensure that everything meets the requirements for optimal performance.
Burst testing reveals how much internal pressure a flow battery can withstand before it breaks apart. We fill the welded part with water and pressurize it until it fails.
Leak testing is done to determine the rate at which air or fluid leaks out. We use this method on flow batteries to prevent any performance issues that could be caused by a leak. There are various methods of leak testing, with the most basic being to fill the part with air, submerge it underwater, and look for bubbles.
Tensile testing is a way to measure how strong a welded part is. Depending on the size, we can either test an entire part or sample by cutting a small section from a larger part. The process entails pulling the two halves until breakage and measuring the force with a load cell.
