CNTs Conductive Additive for Lithium Ion Battery

CNTs Conductive Additive is made specially for improving lithium ion battery cycle performance.

CNTs is one of excellent electric conductive nanofibers, it can form conductive network easily in Li-ion battery electrodes, that can also prevent the electrode material from destroying caused by expanding and shrinking of electrode materials during charging and discharging. Thus, the capacity of battery does not decline.

The pure CNTs can’t be dispersed easily, because the CNTs are entangled with each other heavily.

CNTs Conductive Additive is a composite. It is composed of CNTs and a kind of grain electric conductive additives. Adding grain conductive additive to CNTs, the entangled CNTs is separated. As the result, CNTs can be dispersed easily in battery electrode materials. In addition, because of synergetic effect between CNTs and grain materials, the discharge capacity and cycle life of Li-ion battery can be improved remarkably. Further more, after adding CNTs conductive additive, the tap density of battery electrode coatings can increase 10%.

The new version, developed through research led by Yi Cui, assistant professor of materials science and engineering, produces 10 times the amount of electricity of existing lithium-ion, known as Li-ion, batteries. A laptop that now runs on battery for two hours could operate for 20 hours, a boon to ocean-hopping business travelers.
"It's not a small improvement," Cui said. "It's a revolutionary development."

The breakthrough is described in detail in a paper, "High-performance lithium battery anodes using silicon nanowires," published online Dec. 16 in Nature Nanotechnology, written by Cui, his graduate chemistry student Candace Chan and five others.

Also contributing to the paper in Nature Nanotechnology were Halin Peng and Robert A. Huggins of Materials Science and Engineering at Stanford, Gao Liu of Lawrence Berkeley National Laboratory, and Kevin McIlwrath and Xiao Feng Zhang of the electron microscope division of Hitachi High Technologies in Pleasanton, Calif.

Забележителното е батерията.
Бях чел за нова разработка (Харвард или МТИ - не помня) , при която литиевите аку се пълнят вътре с въглеродни нанотръбички, при което капацитета се увеличава до 20 пъти. Дали китайците вече я произвеждат?
Не можах да намеря по картинката производителя на тази батерия.
