Phone battery will be small with salt particles

The lithium batteries we see in cell phones and laptops can be shrunk with salt in the future, but their power output is not reduced.

The bottom line for micro batteries is their structure. AP researchers at the University of California, Berkeley have created a membrane of nanowires. They then placed lithium aluminosilicate layers (including lithium, aluminum, silicon, oxygen) on top of the nanofilm, creating a three-dimensional structure.

Most batteries today are two-dimensional. Three-dimensional structure allows the battery to store more electricity in the same volume unit. In addition, the battery's surface-like texture also makes it easier to transmit electricity to devices.

" We are working on solutions for micro batteries that achieve energy density as traditional lithium-ion batteries ," said Jane Chang, an engineer at the University of California, Berkeley.

But in a few years smaller batteries like salt particles appear in cell phones or laptops, but Philip Collins, a member of the research team, predicts that in the future they will be able to power them. Everything - from microscopic robots to implanted organs in medicine.

" We can make small sensors with salt particles, but we have not figured out how to power them. One day, super-small batteries will power even micro-robots , "Collins said.
