The latest rechargeable batteries have very high energetic densities; this means, they are really good storing large quantities of load. In order to obtain this density, they have to sacrifice the speed of energetic transference, that are relatively poor (they are quite slow, both loading and discharging this energy).
By creating a new superficial structure, now the lithium ions can move rapidly on the external part of the material. The treated material is also not so rapidly degraded by the repetitive cycles on charge and discharge.
This will allow manufacturing smaller lightweight batteries (for mobile phones and other devices). Reloading will take now seconds instead of hours.
This could also allow fast reloading of batteries for electrical cars, although this particular application was limited in the past by the amount of energy available the net could supply to the owner´s home.
Given the fact that this material is not entirely new, (researchers just have changed the way of manufacturing it), Ceder believes that the fruits of his work could reach the market in just two or three years.
Research has been financed by the National Science Foundation through its Materials Research Science and Engineering Centers program and the Batteries for Advanced Transportation Program of the U.S. The treatment process has already been patented.
There are many users of ideas4all with proposals of many ideas related with new methods for loading mobile phone batteries, MP3 players and more devices of daily use. Here are just a few examples:
