Engineers boost battery strength with small holes - lithium ion batteries for sale
The batteries of mobile phones and laptops can be charged quickly, charging 10 times faster, and charging 10 times faster than the current technology allows.
Engineers at Northwestern University have changed the material of lithium.
Ion batteries that enhance their capabilities.
One change is to poke millions of small holes in the battery.
Scientists estimate that batteries made using this new technology may be sold in stores within five years.
Mobile phone batteries made using Northwest technology will be charged from the apartment within 15 minutes and will last for a week before they need to be charged.
The density and movement of lithium ion is the key to this process.
Dr Harold Kong of Northwestern University and his team say they have found a way to fill more ions by changing the material used to make the battery and speed up their movement
By replacing silicon wafers with tiny clusters of matter to increase the amount of lithium ion the battery can hold, the maximum charge increases.
The chemical oxidation process of drilling small holes speeds up the charging speedjust 20-
40 nm widein the atom-
A thick sheet made of graphene.
This helps the lithium ion move and find the place to store faster.
The downside is that after the battery is charged about 150 times, the charging and power gain drop sharply.
"Even after 150 charges, the battery is still five times more effective than lithium, which will be running for one year or more
"Ion batteries on the market today," said Professor Harold Kong, chief scientist at the Department of Chemical and Biological Engineering at Northwestern University.
The work done by the team so far has focused on improving the anode-
When the battery provides power, the current flows into the battery.
The team now plans to study the cathode-
Where the current flows-
Make further improvements.
