5 New Battery Technologies That Could CHANGE EVERYTHING

A prototype battery that can wholly charge and discharge Total in a few seconds, it consists only of salt water and non-toxic polymers. An additional feature is the color change of components depending on the charge level, which serves as a visual indicator.

In the present time the most common are lithium-ion batteries. Although they have relatively high capacities, but they slowly accumulate and release energy, and also contain harmful and flammable materials, which complicates their disposal. but Recently, a team of researchers from Imperial College London created a prototype of a new type of battery using only thin films of special plastic and water-based electrolytes.

The breakthrough was facilitated by the development of polymeric materials that are capable of releasing and absorbing salt water ions quickly and reversibly without breaking down.. When charging, ions are attracted to oppositely charged electrodes and initially scholars faced the problem of reversibility of this process.

To solve it team developed side chains attached to conductive polymer «highways». Using polar materials, they created electrodes with a high affinity for water.. Thanks to this they made positive and negative electrodes, which can interact with opposite ions from water. Insofar as polymer frameworks were already flexible, expanding and contracting during operation, no additional admixtures were required.

Presented prototype can very quickly charge and discharge, non-toxic and non-flammable, but has less indicators energy intensity, than lithium-ion batteries. Feature of the new option also is an changing the color of components in the process work, what allows visually determine the current charge level.

Although technology not will be able supplant more efficient types of batteries, but its unique properties can be used in various fields. Such devices can become an additional option for environmental storage for solar panels, wind turbines or electric vehicles, allowing use braking energy for acceleration, after just a couple of seconds. TO to that the same such batteries may have enough big sizes.

Further researchers will check the maximum charge storage potential.

Recall that earlier Honda announced the development new a type of battery that stores 10 times more energy than lithium.
