The role of batteries in near-future energetics.

1. Slavko Mentus, Serbia

Since the first oil crysis in early 70-ties, the electrochemists invest effort to develop a power source able to replace the liquid fossil fuels in trafic. Noticeable success was achieved in the decade 1980-1889. Thanks to a new class of materials – intercalate compounds, a new battery called lithium-ion battery was commercialized, having multiple higher energy density than its predecessors. In this presentation the origin of its high energy is explained. The emergence of new battery contributed significantly to the development of mobile phones, lap-top calculators and other portable electronics. Since 2010, relied to the action of OUN to terminate the emission of CO2 in atmosphere by 2050., the batteries became the energy sources of electric cars. Connected to the rising use of solar and wind energy, batteries take also the role of grid energy storage, to level the disturbances in grid voltage. This huge rise in batteries usage state a question about the availability of the resources for battery production: lithium, cobalt and nickel. The forecast is that these resources will be exhausted in the decade 2030-2040. Thus, there is a strong need to search for new battery types, to leave, at least partly, available lithium resources for more demanding applications. The clossest to a practical solution is sodium-ion battery, but the other theoretically perspective types will be mentioned, subjected to the current investigations.
