Richland, wash. – Sometimes, to grow up, you must first go small. This is on researchers Pacific Northwest National Laboratory of Energy Department Energy is done with its latest innovation in storage.
With the target of speeding up time for the discovery of new grid energy storage technology, the team designed a compact, high efficiency flow battery test system, which provides equal results of standard lab-scal testing systems, lempowing the magnitude less beginning An order of material is required. New mini flow cell design and practical verification is Described in an article published in The Journal of the Electrochemical SocietyThe re -designed mini flow cell closely mimics a traditional flow cell’s internal structure, which is increased below by a factor of 5. But, despite its small size, the mini flow cell displays comparable performance to its large counterpart.
Mini flow battery gives big results
“This report is the first step, showing that to reduce our experimental system functions,” material scientific and flow battery researcher said Ruzhu FengA prominent writer of the study. “Our ultimate goal is to bring the power of AI and robotics into this process to automate and intensify the testing of new flow battery design.”
By reducing the quantity of the required material and accelerating the verification process, this technique can help further renewable energy solutions. Researchers also believe that this short approach will facilitate experimentation with a wide range of experimental chemistry.
“Currently, we have to prepare a lot of materials when we identify a promising new battery formula, and it takes a lot of time,” Feng said. “With this mini flow cell process, we can find out that a proposed new content works only with a small amount – Miligram -available.”
Mini flow cell design is extended towards research laboratories that focus on rapid screening and development of new battery materials. In its research study, the team showed that the new mini flow cell material is suitable for rapid verification of stability. Strict testing on a wide range of material chemistry and concentrations helped promote the confidence of researchers in the new scale-down system. However, the team pays attention that this requires extremely pure early ingredients that are free from impurities that can otherwise prevent narrow channels and tubes.
The research team has applied for US patent protection for its new battery design. To learn more about new technology related cooperation or licensing opportunitiesContact our commercialization team.
Efforts of a team
According to the lead researcher and designer of the mini flow cell, the key to their success, Sohan kimIt was that the team had more than a decade experience in the flow battery cell design along with the experience of engineering, efficient machining and chemistry. For example, PNNL Instrumentation and System Control Experts Andry liu Used your mechanical engineering and microfluidics experience to meet the scale without renunciation of accuracy.
“From small cells to large piles, we can handle all the parameters of flow battery design and experiment,” said Kim, a major research of PNNL’s grid storage launchpad. “When we combine computational expertise and analytical chemistry experience, it is how we added efforts to develop mini flow cells. Our hope is to provide it to all the researchers who are interested in using it. ,
What is flow battery?
As their name suggests, the flow battery has two chambers, each of which is filled with separate liquid. The battery charges through an electrochemical reaction and store energy in chemical bonds. When associated with an external circuit, they release the energy that can provide electricity to electrical equipment. Flow battery is a lynchpin technique-they stores energy from intermittent energy sources such as wind and hydroelectric power, and then release that energy on the demand for grid-scale applications. Unlike traditional batteries, the flow battery uses liquid electrolytes stored in external tanks, providing flexible scaling of energy capacity.
Why is the new flow battery design required?
To make the flow battery system practical for massive use, researchers are looking for new chemical and physical combinations that address the boundaries of existing systems. Some of these borders include high content costs, low power density and domestic source material will in the United States.
How is the new flow battery discovered?
Traditionally, the discovery of new materials for flow batteries has been a laborious testing-and-trunk process, which often requires organic compounds, comprehensive testing and gram-scale synthesis of significant time investment. This new short cell design, about the size of a playing card, uses equal to some grains of sand, significantly reduces the time and resources required for each test, while still provides reliable results.
