Thirty already interested companies

In a scientific paper just published by Nature Communications, the researchers explain that the width of their pores Kevlar measure between 15 and 20 nanometers. modern home design bedroom Large enough to let the lithium ions while blocking dendrites whose end is between 20 and 50 nanometers.

"The specificity of this material is that we can make very fine so as to obtain more energy with the same size cell or we can also reduce the size of the cell," said Dan Vanderley, one of the engineers who co-founded the company Elegus. In other words, this innovation will create lithium-ion batteries more efficient while at the same size or smaller. Thirty companies have already asked for a sample of this material. On its website, Elegus Technologies said its Kevlar can also work with lithium-sulfur and lithium-air. It has started mass production of its product from the fourth quarter of 2016.
