Sony Is Working on Sulfur Batteries For Smartphones That Could Last 40% Longer
The mobile industry has grown rapidly with its introduction of high-resolution touch screens, massive smartphones that can perform complex tasks, and chipsets that can parallel certain computers.
All this though has come at a hefty price: battery time. Many manufacturers have attempted to offer alternatives to relatively poor battery performances with substitutes like fast-charging, wireless charging, and docks, but nothing supremely satisfying has come to fruition.
Sony apparently acknowledges this problem, and are reportedly in pursuit of making a new type of smartphone battery that lasts 40% longer on a single charge compared to your conventional lithium polymer batteries.
The report from Japanese site Nikkei suggests that Sony is working with batteries based on a sulfur compound rather than one that uses lithium.
Sulfur batteries aren’t a new idea. The attempt at creating sulfur batteries in the past though have seen various problems, such as electrodes dissolving power at a faster rate than in lithium cells. Sony apparently has managed to change the electrolyte solution to prevent this from happening.
The overall capacity of sulfur batteries however is much larger than a comparable lithium battery, which would not only allow them to work more efficiently, but also encourage the manufacturing of even slimmer smartphones in the future.
It might still take a very long time to bring this battery technology to consumers though. Sony is said to be currently safety testing its sulfur technology.
