New Battery Promises Five Times More Energy

New battery promises five times more energy

Scientists around the world are currently working on techniques for efficient, lightweight and durable batteries. Two researchers from Rome have crossed two technologies into a new type of battery that promises a much higher energy density.

BERLIN. Tablet PCs, mobile phones, electric cars – more and more applications need batteries for power. They should be easy to deliver more power and last a long time. The development of such power memory researchers are working around the world. Two scientists from the University of Rome have found a way to build durable and powerful batteries, which are also suitable for electric cars.

These have combined Bruno Scrosati, and Yusef Hassoun, the advantages of a lithium-ion batteries and a lithium-sulfur batteries. Although the latter has a higher energy density than lithium-ion battery. The problem is that its electrodes are resolved with time.

In addition to electrodes, which consist of a metal such as lithium, branches, called dendrites, train, can lead to short circuits. To incorporate the electrodes in lithium-ion batteries are not made of metal but of a material, the lithium ions, and can unlock it. Often the graphite.

Combination of two techniques

Scrosati and Hassoun is now combined the two techniques into a tin-sulfur-lithium-ion battery. The negative electrode consists of a composite material of carbon and lithium sulfide, the positive from Zinnnanopartikeln in a carbon shell.

The organic electrolyte solution, the scientists replaced by a lithiumionenhaltige liquid that is trapped in a gel-polymer membrane. Thus, the fluid does not come into contact with the electrodes, which protects the electrodes.

The specific energy of the tin-sulfur lithium-ion battery is five times higher than conventional batteries, the two researchers write in an article in the German journal “Angewandte Chemie”, which is published by the German Chemical Society. The replacement of the liquid electrolyte through the polymer membrane also simplifies the manufacture of the battery and make it safer, the researchers say.
