Battery Tips

Today students have never complained about which mobile phone and laptop batteries are not to force it? Clearly, the battery life has become a phone / tablet biggest performance bottleneck. The good news is that the latest technology will soon make their charge rate and battery life has increased more than 10 times.

This magical effect from Northwestern University, the researchers adjusted the charge material, the use of silicon. Traditional lithium-ion battery electrolyte in the activities by the electrons to charge, more effective alternative material is silicon, because each silicon atomic energy with four lithium atoms, while the ordinary graphite anode battery every six carbon atoms with only a lithium atoms.

Although silicon is a good alternative materials, but it is charging process is very easy to expand and contract, resulting in damage to the battery. To solve this problem, Northwestern University research team will graphene sheets and folders into a sandwich-like silicon, to avoid the fragile battery problem (do not fly so ye listen to squeeze …..)

Researchers are still thin on the drilled holes 10 and 20 nm, to shorten the charging time. Next, the research team also talk about improving the battery cathode and electrolyte, the battery is disconnected automatically after a full, good to prevent the battery temperature is too high due to fire or explosion.

Speaking of ignoring the many more dangerous situations that may occur after the use of silicon super cell is still pretty to look forward to, Xiaobian hope that it soon out of the laboratory for the benefit of the masses.
