Researchers at Canada's University of Waterloo have discovered a new battery technology that uses lithium sulphur - this breakthrough may lead to batteries with almost three times as much battery life as lithium ion batteries.
Featuring everyone's favourite technology panacea – carbon nanorods – the system works in a similar way to standard lithium ion batteries: energy is stored in one electrode and released via the second. Unlike standard lithium ion batteries, however, the material is paired with mesoporous carbon nanorods joined by sulphur – allowing the team to charge the device up to 84 percent of the theoretical maximum capacity of sulphur.
Another advantage of the new technology is in weight reduction: the new material is able to store 1,200 watt-hours per kilogramme, compared to just 500 watt-hours per kilogramme for standard lithium ion batteries. This offers a choice: batteries can stay the same weight and hold a great deal more charge, or can slim down dramatically while still offering the same battery life for your devices.
