RPI researchers develop new aqueous Li-ion battery that improves safety without sacrificing performance

Green Car Congress

As the lithium-ion batteries that currently power most phones, laptops, and electric vehicles become increasingly fast-charging and high-performing, they also grow increasingly expensive and flammable. If you apply too much voltage to water it electrolyzes, meaning the water breaks up into hydrogen and oxygen.

Researchers fabricate high-performance 3D silicon anodes for Li-ion batteries from reed leaves

Green Car Congress

Nanoporous silicon is considered an attractive next-generation anode material in lithium-ion batteries due to its much higher theoretical capacity and lower operating voltage than the commonly used graphitic carbon materials. Reeds, as the typical members of the Poaceae family, grow in along rivers, or in shallow water near ponds.
