Smartphones are a necessity nowadays, especially for those who absolutely cannot leave their houses without having their handheld devices clutched in their hands or safely tucked in their pockets. Having many fans and consumers has lead a lot of companies to produce the best possible phone, app or feature that they think will not only enhance the users' experience, but completely ensnare their loyalty.

But equipment and software improvements don't matter much, especially if the power capability of the device is low or isn't enough for all these improvements. Many companies have been coming up with how to fix this problem inherent in their phones. Currently the public had to settle for portable, fast and wireless chargers and/or docks.

With this in mind, Sony recognizes the problem and is reportedly making a new type of smartphone battery. This battery will last 40% longer on a single charge than that of the standard lithium polymer batteries.

Reports say that the new type of battery that Sony is currently working on will be based on a sulfur compound instead of lithium. Although the idea of sulfur batteries isn't foreign, the attempt made in the past to make it possible has seen more problems up until now.

One of the issues that concern such type of batteries include electrodes dissolving power at a faster rate than those of lithium cells; which was reportedly solved by Sony through a change in the electrolyte solution.

The overall potential of sulfur batteries is far larger than that of lithium batteries. With this type of battery, more work is done efficiently and might be able to encourage manufacturers to have slimmer smartphones in the future. So far, Sony is said to be still on the testing phase of their sulfur battery technology, so it might take a while before the public sees it up for sale on the market.
