Jelly Batteries, You see the term “jelly battery and alarms immediately start ringing in your head. Undoubtedly, something that sounds so ridiculous it can not be any real benefit, right? In this case, however, could be a very pleasant discovery.
The so-called “jelly” is really a new material, a type of polymer gel that could be used as a replacement for the liquid electrolyte used in most lithium batteries today.
A lot of technology companies have had problems with the battery safety in recent times. Last year, HP had to recall 54,000 laptop batteries after the start of overheating and fires.
In addition, many have criticized intelligent battery life short.
Obviously, there is much room for improvement in regard to making batteries more secure, lightweight and durable.
We spoke to the Leeds research team to discuss what this means in terms of developing real-world applications.
The true essence of development is the use of a new polymer gel to replace the liquid electrolyte to form a solid and secure thin-film battery, without significant loss of performance.
We have also developed a fully automated extrusion / lamination process that can produce a thin film and flexible laminate battery material at high speed and low cost.
This not only reduces capital investment but also eliminates the need for separation materials which can account for about 10 percent of production costs.
The University of Leeds plans to create a spin-out company to commercialize the technology and we hope to begin to be marketed for the simplest applications of the battery within a couple of years.
Large energy storage systems, for example, electric vehicles are more complex and are likely to require a longer development period.
Technology helps in a couple of ways. First, the technology helps to Leeds by thin-producing cells of the battery, allowing a higher energy density for the same space or, indeed, a smaller battery.
Secondly, the battery performance is dictated by the electrode materials used, what others offer. However, this benefit of electrolytes must be compatible with most electrode systems based lithium-ion.
The technology has been licensed to a U.S. company – Polystor Energy Corporation – which is the testing for the marketing of the cells of the portable consumer electronics.
