Stanford Engineers Create Urea Battery for Low-Cost Energy Storage

A pair of Stanford engineers have put their heads together to come up with a sustainable battery storage option for solar energy and wind energy. The said battery is affordable, efficient, non-flammable and lasts for a long period.

The battery, which was developed by Hongjie Dai, a chemistry professor at Stanford University, and Doctoral candidate, Michael Angell is made with urea, which is commonly found in mammal urine and fertilizers. It possesses a capacity to store energy produced through solar power, wind power, and other forms of renewable energy, for off hours. It also contains electrodes made from aluminum, and graphite.

According to Professor Dai, “So essentially, what you have is a battery made with some of the cheapest and most abundant materials you can find on Earth. And it actually has good performance. Who would have thought you could take graphite, aluminum, urea, and actually make a battery that can cycle for a pretty long time?”

The previous version of the aluminum battery was also efficient, but acquired a very expensive electrode, unlike the recent battery, which uses urea already being produced in large quantities for fertilizers as its electrode.
I would feel safe if my backup battery in my house is made of urea with little chance of causing fire.” – Dai
