Exploring electrolysis for energy storage
Jan 03, 2018
Interest in renewable energy continues to grow. Many renewables, though, can be frustratingly intermittent. When the sun stis obscured by clouds, or the wind stops blowing, the power fluctuates. The fluctuating supply can ...
Cheap, sustainable battery made from tree bark tannins
Dec 18, 2017 feature
(Phys.org)—Tannins may be best known for their presence in red wine and tea, but in a new study researchers have demonstrated for the first time that tannins from tree bark can also serve as battery cathode materials. As ...
