For many years, experts are trying to improve lithium batteries by replacing them in graphite on flint. This would allow up to ten times to increase their capacity with the same size, but the obstacle is the short lifespan of these power sources. A few charge cycles lead to the destruction of silicon anode structure . A group of scientists - materials science from Stanford University, led by Yi Cui (Yi Cui), seems to have solved the problem with the stability of the silicon anode .
The new anode consists of a silicon nanotube with a double wall and an external ceramic coating. The outer layer prevents the extension of work, and subsequently allows the tubes to remain intact, while the size of tubes do not prevent the penetration of electrolyte into the anode of the molecules. The result is an anode, which is able to survive more than six thousand recharge cycles with a maximum capacity of about 15 percent. The team is now working on Cui simplification of anode production process , as well as designing the battery, which is estimated to be 5 times more efficient than today's lithium-ion counterparts.
