The current state of researches of sodium – ion batteries is discussed. The main problem constraining creation of competitive sodium – ion batteries, is low efficiency of the available electrode materials. The main efforts on creation of anodes for sodium – ion batteries come down to development of materials based on carbon, metals, alloys and oxides of transitional metals. Materials based on oxide and salt systems are developed for cathodes. Significantly less attention is paid to synthesis of electrolytes for sodium-ion batteries.
