The batteries charge through an electrochemical reaction and store energy in chemical bonds. When connected to an external circuit, they release that energy, which can power electrical devices.<\/p>\n<p>Flow batteries are a linchpin technology\u2014they store energy from intermittent energy sources such as wind and hydroelectric power, and then release that energy on demand for grid-scale applications. Unlike traditional batteries, flow batteries use liquid electrolytes stored in external tanks, providing flexible scaling of energy capacity.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Why_are_new_flow_battery_designs_needed\"><\/span>Why are new flow battery designs needed?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>To make flow battery systems practical for large-scale use, researchers are seeking new chemical and material combinations that address limitations of existing systems.
