Product Description
18650 850mAh 35C 2.90V Sodium-Ion Battery
Features
- Inherent Safety: Sodium-ion chemistry is often considered less prone to thermal runaway compared to some high-energy lithium-ion chemistries, enhancing safety .
-
High Power Capability (35C): Capable of delivering very high discharge currents (up to ~29.75A continuously), making it suitable for power-intensive applications.
-
Excellent Low-Temperature Performance: Typically performs better than lithium-ion batteries in low-temperature environments .
-
Fast Charging: Supports rapid charging, potentially up to 1C or higher.
-
Abundant Raw Materials: Utilizes sodium, which is more abundant and geographically widespread than lithium, potentially leading to lower long-term costs and better supply chain stability.
-
Environmentally Friendly: Some chemistries can be made from more environmentally benign materials and may have a simpler recycling process.

Warnings & Safety Instructions
Charging
- Use Designated Chargers: Charge only with a charger designed for sodium-ion batteries with the correct voltage and current limits. Using a lithium-ion charger is unsafe.
-
Temperature Control: Do not charge outside the specified temperature range (0°C to +55°C). Charging below 0°C may cause plating and permanent damage; charging above 55°C is hazardous.
-
Voltage/Current Limits: Do not exceed the maximum charge voltage or current.
Discharging
- Current Limit: While rated for 35C continuous discharge, avoid sustained operation at the maximum limit in high-temperature environments to preserve cycle life.
-
Voltage Limit: Do not discharge below the cut-off voltage (2.0V). Deep discharge can damage the battery.
-
Temperature: Monitor battery temperature during high-rate discharge.
Storage
- Ideal Storage Charge: For long-term storage, store the battery at a state of charge between 30% and 50%.
-
Storage Environment: Store in a cool, dry place away from direct sunlight and moisture.
