The proliferation of mobile devices, connected objects, let alone electric cars, makes this type of batteries for the moment unavoidable and ubiquitous in everyday life. So anything that can improve safety is obviously important. Precisely, by a little more than two years, we could see the arrival of lithium-ion batteries safer, thinner and more powerful.
A separator nanofiber
This is certainly what promises Elegus Technologies, a US company founded by researchers at the University of Michigan. They have developed a separator nanofiber Kevlar which is inserted between the anode and the cathode while leaving circulate ions. modern home design books The membrane prevents the formation of dendrites. These growths are formed in the long under the effect of contraction and swelling experienced by the lithium during the charge-discharge cycles. These dendrites can damage the polymer separator that insulates the anode and the cathode and cause a short circuit that could lead to fire or explosion of the battery.
It is from Kevlar, the material used in the particular body armor, the company Elegus Technologies extracted nanofibers to manufacture its electrode separator for lithium-ion batteries. © Joseph Xu, Michigan Engineering, Communications & Marketing
