MIT Develops Battery To Store Thermal Energy For Hours

By Brian Spaen

Solar power is one of the most common renewable sources of energy out there, but we still struggle to use it efficiently. In recent years, developing lithium-ion batteries as a way to store energy has been gaining popularity. Researchers at MIT have recently unveiled a new battery that stores thermal energy to for hours at a time, offering up a new and exciting potential for renewable energy.

Tesla and other companies that have been jumping into the solar energy industry focused on developing lithium-ion battery solutions for storage. Since the sun isn’t up for 24 hours each day, these batteries kick in at night, or when sunlight isn’t optimal. There are good reasons to use li-ion technology, including a long life, little maintenance, and it can handle the heat created from the sun to an extent.

However, li-ion batteries do pose their own problems. This includes higher expenses than the alternatives, the batteries deteriorating after every charge, and the heat does pose a chance for them to catch fire if there’s any malfunctions. For these reasons, scientists at the Massachusetts Institute of Technology have created a battery that can store thermal energy and it can discharge on command.
