Product Description
Sodium Ion Battery 40160 3.1V Cells 17.5ah 20ah 2000 Cycles
Features
- Inherent Safety: Sodium-ion chemistry is considered more stable and less prone to thermal runaway than some high-energy lithium-ion chemistries, contributing to enhanced safety.
-
Excellent Low-Temperature Performance: Maintains good functionality in cold environments, with discharge capacity retention exceeding 80% at -20°C .
-
Long Cycle Life: Engineered for long-term use, with a cycle life of ≥2000 cycles , and some variants reaching ≥3000 cycles (to 80% of initial capacity), reducing the frequency of replacement.
-
Fast Charging Capability: Supports relatively fast charging; some sodium-ion battery variants can support 2C fast charge, reaching 90% state of charge in about 30 minutes .
-
Cost-Effective & Sustainable: Sodium resources are more abundant and widely distributed than lithium, potentially leading to lower long-term costs and better supply chain stability .

Warnings & Safety Instructions
Charging
- Use Designated Chargers: Charge only with a charger specifically designed for sodium-ion batteries with the correct voltage and current limits. Using an incorrect charger, especially one designed for lithium-ion or lead-acid batteries, is dangerous.
- Temperature Control: Do not charge outside the recommended temperature range (e.g., -20°C to +55°C ). Charging in extreme temperatures can cause permanent damage or hazards.
- Avoid Overcharging: Do not leave the battery connected to the charger indefinitely after it is fully charged.
Discharging
- Voltage Limit: Do not discharge the battery below the recommended cut-off voltage (e.g., ~1.8V ). Deep discharge can irreversibly damage the battery.
-
Current Limit: Do not exceed the maximum continuous discharge current specified by the manufacturer.
-
Temperature Monitoring: If the battery becomes excessively hot during use, stop operation and allow it to cool down.
Storage & Disposal
- Ideal Storage Charge: For long-term storage, store the battery at a state of charge between 30% and 50% in a cool, dry place.
-
Storage Environment: Store away from direct sunlight, heat sources, and moisture. The recommended storage temperature for a similar Na-ion cell is +15°C to +35°C .
-
Disposal: Do not dispose of in regular trash. As a rechargeable battery, it must be recycled or disposed of according to local regulations at designated battery recycling centers.
