Sodno-iontové akumulátory - budoucnost a aktuální vývoj

Sodium-ion Batteries – Future and Developsment

conference paper

The lithium-ion technology is widely known and spread technology. The based of this technology lies on transport of lithium ions during charging or discharging from one electrode to the other, this principle is call “rocking chair”. Nowadays, this leading battery technology finds a wide range of applications from cell phones through electric vehicles up to high capacity stationary storage systems. With growing field of the application of lithium-ion batteries, the demands arising from the individual applications brings new point of view and requirements onto lithium-ion technology. For example, the area of renewable energy along with utilization of energy produced, from them calls for large energy systems storage, because all these sources are undispatchable. Currently, the lithium-ion technology has majority share in these applications, but the technology has the limitations. Main of them is the lithium elements itself, the lithium production growing very fast in recent few year and new lithium ore sources are sought. But the production of lithium does not enough supply the growing demand that leads to increasing price of lithium metal. Each renewable energy sources need to be supported with high capacity energy storage systems, the requirements to these systems are the environment friendly as much as can be and low-price. These are some but not all essential characteristics of new generation of energy storage systems. There are few new promising systems that belong among the so-called post-lithium systems like lithium-sulphur, lithium-air, magnesium battery or sodium-ion battery. These systems are development or laboratory-basic research level due to many disadvantages which must be overcome. As one of the most promising system, seems to be sodium-ion, this system removes cost and environment risk and looks like promising candidate for renewable energy large capacity energy storage system.
