Have you ever wished you could increase your cellphone battery life? Well, that technology may very well already be here.

Researchers from AMBER, the Science Foundation Ireland Research Centre for Advanced Materials and BioEngineering, at Trinity College Dublin, have announced the development of a new material which offers the potential to improve battery life in everyday electronics, like smartphones, according to Irish Tech News.

The discovery could mean that the average phone battery life, roughly 10 hours of talk time, could increase to 30-40 hours.

MXenes, an ink-based nanomaterial, not only significantly improves battery life, but it also offers its batteries the flexibility to become smaller in size, without losing performance. (more…)

Materials scientists have developed a new technique that could provide a simpler and more effective way to produce electrode materials for batteries and supercapacitors, which could potentially lead to devices with improved energy and power densities.

The researchers have unlocked this new battery technology by exposing tiny bits of graphene to a process that is very similar to deep-frying.

Prior to this development, scientists had difficulty using graphene in electrodes due to the difficulty encountered when processing the material. However, the researchers out of Yonsei University have learned how to harness the material’s electrical and mechanical properties while retaining its high surface are by using an alternative technique.
