Innovation at MIT in batteries

An innovation at MIT will allow the creation of lithium-ion batteries, which may well be lighter, and will be recharged in seconds.


The technology developed by scientists at MIT, allowing to quickly reload the future lithium-ion batteries for devices such as mobile phones.

The lithium-ion batteries are widely used in portable electronic devices because they have the capacity to store large amounts of energy. The downside, however, is that it takes many hours to recharge them, which is mostly annoying especially for people who move constantly.

A team of scientists at MIT, led by Professor Gerbrand Cedar, discovered that the lithium ions, which carry energy in the battery can deliver faster when aligned with tunnels that are accessible from the surface of the battery.

It is possible to rearrange the surface of the battery to allow lithium ions to move faster across the surface. A model recently developed battery may recharge in less than 20 seconds.
