‘Expected to open a new field’

University researchers in China have made a potentially massive breakthrough in battery technology that could make large-scale versions even more affordable and widely available.

According to

, scientists at the Dalian Institute of Chemical Physics have created new molecules for aqueous organic flow batteries. The new organic redox-active molecules, or ORAMs, could make the battery technology more stable, scalable, and accessible.

Aqueous organic flow batteries, or AOFBs, generate electrical current with components dissolved in liquids stored on opposite sides of a membrane, as Interesting Engineering

Per the news report, most redox flow batteries use precious metals like vanadium, which is incredibly rare, making them difficult to mass-produce. On top of that, many of the ORAMs used in that type of battery have a tendency to deactivate because of side reactions in the battery that occur when the materials used in the battery react with outside elements (the reactions are supposed to occur within the battery), especially when used without the protection of inert gas (per the

found that the battery worked for about 22 days when exposed to continuous airflow “without obvious capacity decay.”

This new technology could make large-scale AOFBs more affordable, durable, and capable of sustaining power over longer periods of time. As we move away from ****** energy sources, new batteries for energy storage are even more important. Recently, researchers created batteries powered by potassium ions, rather than the usual lithium ions. They’ve also made breakthroughs to help transition to renewable energy forms through new liquid batteries as well as salt and air-powered batteries.

The researchers hope that their new findings will allow for more research into the viability of AOFBs and push the technology forward.

“This study is expected to open a new field in the design of air-stable molecular for sustainable and air-stable electrochemical energy storage,” Li said in the press release, per
