Comparison of Sodium ion Battery and Lithium ion Battery
1- Overview
Sodium ion battery (SIB) and lithium-ion battery (LIB) are two important rechargeable battery technologies. Lithium ion batteries dominate the fields of consumer electronics and electric vehicles due to their high energy density and long cycle life. However, the limited and uneven distribution of lithium resources has prompted people to seek alternatives. Sodium ion batteries have become a strong competitor to lithium-ion batteries due to their abundant sodium resources and low cost.
