However, as the demand for renewable energy storage solutions increases, the market for sodium-ion batteries is expected to grow significantly in the coming years.

18650 sodium ion cell introduction

18650 sodium-ion cells are a type of rechargeable battery that uses sodium ions as the charge carriers instead of lithium ions. These cells are named after their size, which is 18mm in diameter and 65mm in length. They have a similar form factor to lithium 18650 battery, making them compatible with existing devices designed for lithium-ion batteries.

The voltage of 18650 sodium ion cell is typically lower than that of lithium-ion cells, with a voltage of around 2.8 to 3.5 volts per cell. This is because the electrochemical properties of sodium-ion cells are different from lithium-ion cells, leading to a lower voltage output.

However, this lower voltage is not necessarily a disadvantage, as it can be compensated by using more cells in series to achieve the desired voltage levels for specific applications. Additionally, the use of sodium-ion cells can offer advantages such as higher safety, lower cost, and better environmental sustainability compared to lithium-ion cells.
