Cheap And Efficient Jelly Batteries For The Future

The future of portable device batteries is here, and it’s set to revolutionize how we power our gadgets. Soon, devices like the HTC Thunderbolt and EVO 4G could last more than a day without needing a spare battery.

Researchers from the University of Leeds have developed a groundbreaking polymer gel that promises to change the game in battery technology. This flexible gel can be molded into any shape, making it adaptable to a wide range of devices.

The innovative gel is the brainchild of Professor Ian Ward and his research team. They have eliminated the need for the porous polymer film separators traditionally used in lithium-ion batteries.

Their patented Extrusion/Lamination manufacturing process embeds the electrolyte gel between the battery's cathode and anode at an impressive rate of 10 meters per minute.

This gel consists of 70% liquid electrolyte and is created using a process similar to making jellies—hot electrolyte is mixed with a polymer, and as it cools, it solidifies into a flexible, durable structure.

Despite being nanometers thin, the gel strip is safer, lighter, and significantly more powerful than current battery technologies.

Moreover, this new approach reduces manufacturing costs by 10-20% compared to today's lithium-ion batteries.

Commercial trials are already underway at Polystor Energy Corporation, which has licensed the technology. The project has been supported by the Engineering and Physical Sciences Research Council and Yorkshire Concept, pushing the boundaries of battery innovation.
