What is sodium ion battery?

Vcell Power Sodium Ion Battery is a mature, cost-effective rechargeable battery, serving as an ideal supplement to lithium batteries. Its core features are as follows:

· Basic Principle: It is a rechargeable battery. Energy is stored and released via sodium ion movement between electrodes. It works similarly to lithium batteries, with abundant, geo-unrestricted sodium resources.

· Full-tab Structure: Adopts full-tab design to lower internal resistance and optimize heat dissipation. It shortens electron transmission path, supporting faster charge and discharge rates.

· Material & Product Type: Compatible with layered oxides, Prussian blue and polyanionic cathode materials. Vcell Power mainly supplies mature cylindrical sodium ion batteries.

· Technical Experience: Backed by 20+ years of battery manufacturing experience. Founded in 2001, we launched 18650 cells in 2004 and achieved official battery mass production in 2024.

Working Principle of the battery

Charging Process: Sodium ions detach from cathode materials, pass through electrolyte and separator, and intercalate into anode materials. The cathode becomes sodium-deficient while the anode turns sodium-rich.

Discharging Process: Sodium ions separate from the anode and return to the cathode. Electrons flow from the anode to the cathode via external circuits to supply power for equipment.

Advantages of Full-tab Structure

The full-tab structure takes all edges of electrode tabs as current collection points. It shortens electron transmission path and reduces internal resistance, supporting high-rate charge and discharge.

What are the advantages of the battery over traditional lithium batteries?

Compared with conventional lithium batteries, Vcell Power Sodium Ion Battery has the following prominent strengths:

Take 3.0V 10Ah 32140 Cylindrical Sodium Ion Battery as an example. Its cylindrical housing combined with full-tab structure achieves low internal resistance and high-rate performance. It maintains high capacity retention at low temperatures, which brings great value to outdoor energy storage devices in cold northern regions.

How to Select the Right Sodium Ion Battery for Your Project

Follow the steps below to select proper battery:

Step 1: Confirm Voltage Platform

The nominal voltage of single sodium ion cell is 3.0V. Total voltage = 3.0V × Number of cells in series. For example, 16 cells in series form a 48V pack, and 24 cells form a 72V pack.

Step 2: Evaluate Capacity Demand

Take 3.0V 10Ah 32140 Cylindrical Sodium Ion Battery for reference, the capacity of single cell is 10Ah. Calculate total cell quantity based on required total energy, then arrange cells in series and parallel reasonably.

Step 3: Confirm Working Environment

·         Low-temperature operation: Sodium ion battery performs excellently in cold areas.

·         Safety requirements: Our products pass strict needle penetration tests.

·         Cycle life demand: Typical cycle life exceeds 3000 times.

Step 4: Match BMS and Connectors

Sodium ion batteries have different cut-off voltage from lithium batteries, so dedicated BMS is required. Vcell Power provides supporting protection solutions and customized connectors.
