Scientists from the Catholic University of Leuven created a material that has the formula LiTi2 (PS4) 3.
It is in a solid state of aggregation and has the highest lithium mobility coefficient ever measured, according to Naked Science.
This value is explained by the unique structure of the crystal lattice of the material, which previously could not be reproduced in materials based on lithium.
For renewable energy sources, such as solar panels or wind turbines, it is important to have reliable storage devices that could accumulate excess electricity to give them to the network when night falls or windless weather.
Currently, lithium-ion and lithium-polymer batteries are considered the best. They are most effective and cheap in production. However, they also have disadvantages.
For example, such batteries are fire hazardous: they often catch fire during operation due to the influence of environmental factors or manufacturer’s mistakes.
This problem can be solved by replacing the liquid electrolyte in the batteries with a solid one.
This is very difficult to do, since lithium ions in solids are less mobile than in liquids. Lower mobility limits the applicability of the battery, because of this, it has a low capacity and speed of charge and discharge.
However, according to scientists, there is still a lot of research ahead that will improve the material and bring it to the world market.
This discovery is nevertheless an important step in understanding materials with extremely high mobility of lithium ions, which are ultimately necessary for all future solid-state batteries.
