Don’t Eat This Jelly…

A battery using a polymer jelly could make for cheaper, more efficient batteries.

Researchers from the University of Leeds have developed a new type of polymer jelly which could be used to make lighter, cooler (temperature wise) and more efficient rechargable batteries. They could be used in any application which currently uses a lithium battery, such as laptops, cell phones or tablets.

Professor Ian Ward from the University of Leeds went on BBC Radio 4 recently to discuss the new polymer jelly his research group has been working on.

This jelly, he says, could replace the current liquid electrolyte in most lithium batteries. The polymer jelly is supposed to be 10-20% cheaper but will not reach the high temperatures current batteries operate at during long usage times.

It would be regarded as safer because there is no excess solvent or electrolyte. All the solvents are bound into the polymer at a molecular level.

The group set out simply to make batteries safer. But as luck would have it, the design actually makes the batteries cheaper and more efficient.

It will certainly be cheaper because…the process of making batteries at the moment is generally rather laboruious. whereas we can do it in an instant step at a rather fast rate.

The batteries will also end up being lighter for doing similar applications as current electrolyte filled batteries, which will be particularly useful for military applications, says Ward.

This is one of those scientific advances which doesn’t seem too glamourous, but could directly affect all of us. Cell phones, tablets and laptops are ubiquitous now and battery life is a major consideration when buying a new device.

Anyone in the mood for PB&J now?
