In today’s era where technology is the order of the day, one of the biggest problems it presents is battery life. We all wish our devices had infinite battery. Even so, all the companies that create electronic devices focus on creating a battery with the greatest possible autonomy so that it lasts as long as possible on without the need to make a charge. Recently, they have developed new tiny batteries that are capable of storing up to four times more energy thanks to their casing.
It has always been a priority for companies to improve the performance of batteries, in addition to making them charge faster.
Up to four times higher energy density
However, one of the limitations that prevents batteries from having a greater electrical charge capacity is their packaging, which prevents the rapid passage of both electrons and ions.
A group of scientists from the University of Pennsylvania has created tiny and very light batteries that can store up to four times the amount of energy.
This research was carried out with the aim of trying to create new batteries that would last a long time and that would serve as a source of energy for small electronic devices. However, to achieve this usually the only thing that can be done is that the battery increases both its weight and its size.
Changing the battery design, the key
To create these new small batteries the team redesigned the way these types of batteries are made. These types of devices generally have electrodes that allow electrons and ions to pass through. However, its structure limits the amount of energy that can be accumulated.
Therefore, the scientists changed the design of the battery cathode. Typically they are made with crushed particles compressed together in a way that makes a composition where air spaces are created. This influences the movement of the ions within the battery.
However, for the new batteries a very dense material was used to create the cathode that could be put together with thin metal, allowing the case to also accumulate energy. Therefore, this new battery structure facilitates the passage of electrons and ions through the battery.
The design was a complete success, after managing to store four times more energy than with conventional batteries. In addition, it has an energy density up to 100 times greater than its size.
These types of batteries would be ideal for small electronic devices such as robots , portable devices or drones that can be of many types.
