Batteries with high capacity and a long live are the necessary fundaments for the future of distributed power grids. Storing renewable energy is an essential part because the sun is not shining and the wind is not blowing 24 hours a day.
Researchers at the SLAC (National Accelerator Laboratory) discovered a new battery design which was inspired by a fruit: pomegranate. This new concept will modify the Anode part of a battery. It prevents capacity to be degrading as fast as in current designs.
Increased capacity and more discharge cycles
“Experiments showed our pomegranate-inspired anode operates at 97 percent capacity even after 1,000 cycles of charging and discharging, which puts it well within the desired range for commercial operation.”
The anode, or negative electrode, is where energy is stored when a battery charges. Silicon anodes could store 10 times more charge than the graphite anodes in today’s rechargeable lithium-ion batteries. See here for the full article.
