Abstract: A new portable energy storage device based on sodium-ion battery (SIB) has been designed and assembled. Layered oxide NaNi1/3Fe1/3Mn1/3O2 was used as cathode and hard carbon was used as anode. The structure and thermal stability of the prepared material were measured by using XRD and DSC techniques. Soft pack battery with 1 A·h capacity has been designed and the electrochemistry and safety performance were tested. SIB packs of 0.1 kW·h were fabricated for the new portable energy storage device. This sodium ion energy storage device has a promising perspective on household electrical energy storage, military power supply, smart grid, low-speed electric vehicle, etc.

Key words: sodium ion battery, cathode, safety, battery model, portable energy storage device
