Imagine if your house ran on a giant, low-maintenance rechargeable battery. Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) developed a new flow battery capable of lasting more than 10 years. Along with its 10-year lifespan, the researchers also successfully designed the battery to remain inexpensive, non-corrosive, and non-toxic. Led by professors Michael Aziz and Roy Gordon, the groundbreaking research boasts the potential of changing the way people utilize power all over the globe. Aziz and Gordon devised a way to take advantage of the benefits of a flow battery without the energy degradation that occurs while maintaining a traditional flow battery.

A flow battery uses liquid electrolytes to store charges. Two chemical components dissolved in liquids are typically separated from each other in external tanks, with bigger tanks storing more energy than a smaller tank. Generally with flow batteries, all that’s required to recharge them is replacing the liquid electrolytes — the chemical compound that allows for an electrical charge when dissolved. Each time someone replaces the electrolyte liquid, however, the battery grows weaker, making it one of the […]
