A British study believes that the sodium-ion batteries of our future smartphones will be more economical and ecological while having an almost unlimited storage capacity. However this new battery concept has come up against problems regarding the storage of sodium-ions. Nevertheless a solution has recently been found!
Sodium ions are too thick to be stored between the layers of carbon used in the current lithium ion batteries. However in a statement released in September 2018, researchers from Birmingham University believe that they have found a solution concerning the storage of sodium ions. This is an important stage in the process of creating a new market for this new generation of battery.
The storage of sodium ions was the last stumbling block to overcome in the hope that this technology could one day be made more accessible. Able to store 700% more energy than lithium ion batteries, it would be a real shame if researchers were unable to find a solution! Nevertheless after many complex calculations, British researchers have found one! They believe this storage dilemma could be solved by coupling phosphorus and sodium together.
According to scientists, in addition to their improved performance, these new batteries containing a mixture of phosphorus and sodium would be more respectful to the environment. Phosphorus is the eleventh most common element on Earth, and sodium is very abundant, especially in sea salt! In contrast, lithium is much harder to find, and large amounts of water are needed to extract this element. Logically, the cost of manufacturing an sodium-ion battery would be much less expensive
Researchers believe that the mixture of phosphorus and sodium poses no instability issues that can be found with lithium-ion batteries. Everyone will have heard about the many cases of fires starting or explosions linked with this type of battery when it over heats.
The new sodium-ion battery will be more economical and will have a greater storage capacity. What’s more it is more ecological than lithium-ion batteries as there are less steps in the production process. Once more tests and research has been carried out, this new type of battery could feature in the electronic devices of the future!
