The Research progress and comparisons between Lithium-ion battery and Sodium ion battery

Sustainable development and environment-friendly battery has always been the goal pursued by people. At present, lithium-ion battery (LIB) is widely used in electronic products, transportation, aerospace and other fields. However, it has a low storage of Li and uneven distribution. Recently, a new type of secondary cell, sodium ion battery (SIB), appears as novel energy source. It has attracted much attention for abundant resources, low price and friendly environment. But there is few paper about the comparison between LIB and SIB. In this paper, the research progress and classification of materials for LIB and SIB are introduced in detail. In addition, this paper compares them from the aspects of economy and electrochemical performance. Finally, novel idea for the development of SIB is illustrated.
