New breakthroughs in lithium batteries that can double the endurance of electric vehicles

Battery technology is changing with each passing day, and the driving distance of electric vehicles is also improving day by day. Scientists in South Korea have released the latest electric vehicle, which can travel 300 kilometers per charge, has twice the endurance of an ordinary electric vehicle and has more than four times the storage capacity.

Gwangju Institute of Science and Technology (GIST) announced Wednesday that Eom Gwang-sup, a professor of materials science and engineering at GIST, and Lee Jung-tae, a postdoctoral researcher at MIT's Electronics Research Laboratory, are working together to develop the latest lithium batteries. Compared with the products on the market, the new lithium batteries have four times more storage capacity and more battery life. Two times.

Traditional lithium-ion batteries based on graphite, lithium metal oxide (Lithium Metal Oxide) as cathode and anode, due to the capacity of the two kinds of materials are low, at the current development of science and technology, storage capacity is close to the limit, so the electric car battery storage capacity, increase the space is not much.

As a result, the south Korean team decided to use new battery anode material, USES the silicon and sulphur. Scientists specially add selenium to protect the silicon cathode, and thus developed with lithium and silicon of the cathode, in addition to sulfur, selenium anode.

The latest lithium battery storage about 500 grams per MAH power, compared with the battery per gram is only available in the market can store 100-150 MAH power. This on behalf of the electric charge once per can run 300 kilometers, is the general electric double away.
