"New power sources bear a shocking resemblance to the electricity-making organs inside electric eels. These artificial electric eel organs are made up of water-based polymer mixes called hydrogels. Such soft, flexible battery-like devices, described online October 13 in Nature, could power soft robots or next-gen wearable and implantable tech."

"Energy storage could be the next item on the list when it comes to listing all the reasons we need to save the world's bee population from collapse. A research team at Purdue University has found that bee pollen can be used as an efficient, renewable source for anodes in lithium-ion batteries. The team also tested pollen sourced directly from cattails and got even more encouraging results."

"Teeth and bones, snail shells and bird eggs are formed via a process called biomineralization. Found across all kingdoms of life, this method of incorporating minerals like calcium or silica into hard tissues is clearly very useful in nature. The concept is so powerful that researchers are now working on applying it to the rather unnatural environment found within lithium ion batteries."

"The latest development by engineers of Karlsruhe Institute of Technology (KIT, Germany) is inspired by nature. To fill the porous electrodes of lithium-ion batteries more rapidly with liquid electrolyte, they use a physico-chemical effect that also provides for transport in trees. increases the throughput of battery production and reduces investment costs."

"Biomimicry provided the inventive spark for the latest, and most promising, revamp of the rechargeable battery. The rechargeable battery, which so often lets us down at the worst moments, has been due for an overhaul for some time now. Indeed, scientists have been slaving away for years on a lithium-ion battery with a longer lifespan. But who would’ve thought that the inspiration for the most promising new design would come from inside a pomegranate?"
