Lithium-air [LiO2] batteries have a theoretical energy density of some 3,460Wh/kg but in practice hasn’t been able to surpass that of a sodium-air battery at 1,600Wh/kg. Development of the next-generation rechargeable battery is going to directly impact the performance and capabilities of electric vehicles. Current lithium-ion [Li-ion] battery technology has a maximum density of 250Wh/kg, […]

Rechargeable battery technology development isn’t dead by any means, and still needs plenty of research to perfect and improve it. There are perhaps billions of people on the planet who have a great idea on how to make something better. Tinkers, inventors, researchers, and scientists have all this in common, but to get an idea out to […]

A discovery made by researchers at the Karlsruhe Institute of Technology (KIT) can eventually make lithium ion batteries cheaper by improving a key process that currently takes a lot of time to complete: filling the batteries with liquid electrolyte. The porous electrodes inside modern rechargeable batteries have to be properly filled with liquid electrolyte. Actually, […]

Paraffin wax and oleic acid have been discovered to make up good materials for battery electrodes, which could have applicability in electric cars and power storage systems. A team of Pacific Northwest National Laboratory (PNNL) researchers in Richland, WA, have discovered a technique that could turn materials otherwise unsuited for battery electrodes into ones that exceed even today's most advanced.
