If true, that would theoretically allow electronic devices that use the technology about ten times the battery life that they use today, a key advantage for gadgets like power-hungry smartphones.
“We have found a way to extend a new lithium-ion HP 484784-001 battery‘s charge life by 10 times,” said Harold H. Kung, lead author of the paper, in a statement released by the university. “Even after 150 charges, which would be one year or more of operation, the hp probook 4510s battery is still five times more effective than lithium-ion batteries on the market today.”
Normally, lithium-ion batteries are charged by electrons moving from the electrolyte into the anode. Current batteries use anodes made of graphene, which allow one lithium atom per six carbon atoms. Silicon, which allows four lithium atoms per one silicon atom, has been been considered a superior medium for building batteries, but silicon tends to contract and expand significantly during charging, which can cause the lithium-ion hp 484784-001 laptop battery to suffer fragmentation.
Kung’s team sandwiched clusters of silicon between the graphene sheets, which Kung’s team claimed would eliminate or marginalize the fragmentation. They also “drilled” 10- to 20-nm holes in the sheets to speed up the recharging process, by as much as ten times.
According to the university, the next step will be to look at improvements to the cathode and electrolyte. Kung’s team hopes to develop an electrolyte that can be shut off under high temperatures to prevent fires or explosion, then later reversed.
