Rice Husks Could Lead to Longer Battery Life

Rice Husks Could Lead to Longer Battery Life

An agricultural waste product, such as rice husks, is an unlikely source for a material that could lead to better, and longer lasting, batteries. But the results of a recent study suggest that those same rice husks could one day be used to produce silicon anodes for lithium batteries. Researchers at the Korea Advanced Institute of Science and Technology (KAIST) were recently able to convert the silica from rice husks into pure silicon, and then fashioned it into anodes for a high-capacity lithium-ion battery. The resulting battery exhibited no reduction of capacity after 200 charge cycles, which suggests that the… read more

Greener Batteries Could Be Made From Plants

Greener Batteries Could Be Made From Plants

The roots from a plant may someday be used to make greener batteries. That is what scientists who discovered that purpurin, a substance that can be extracted from the root of the madder plant, found. The group of researchers learned that it is possible to make rechargeable lithium ion batteries from this material as it can be implemented as a natural cathode. The plant, categorically known as Rubia tinctorum, has traditionally been used as a natural dye. When examining ways to use organic molecule properties and their capacity to work with lithium ion, they discovered purpurin’s effectiveness as a better rechargeable… read more
