Product Description

Sodium-Ion Battery 3V 200ah Brand New Grade a Na Cell for Home Energy Storage

Key Features

Enhanced Safety: Sodium-ion chemistry is inherently more stable, offering higher resistance to thermal runaway, and often passes stringent tests like overcharge, short-circuit, and nail penetration without fire or explosion.
Excellent Low-Temperature Performance: Maintains strong functionality in cold environments, with discharge capacity retention of over 85% at -20°C.
Long Cycle Life: Engineered for long-term use, with a cycle life of 3,000 cycles or more (to 80% of initial capacity), reducing the frequency of replacement.
Cost-Effective & Sustainable: Sodium resources are abundant and widely distributed, leading to lower material costs (typically 30%-40% lower than lithium-ion) and a more stable supply chain.
Fast Charging Capability: Supports relatively fast charging; some Na-Ion batteries can support 2C fast charging.

Applications

Home Energy Storage Systems (ESS): Integration with solar PV systems for self-consumption, backup power, and load shifting.
Commercial & Industrial Energy Storage: Medium to large-scale energy storage for peak shaving and grid support.
Uninterruptible Power Supplies (UPS): Backup power for critical home or office equipment.
Low-Speed Electric Vehicles & Electric Bicycles: Where weight is less critical than cost and low-temperature performance.

Safety Instructions & Warnings

Charging

Use Designated Chargers/Controllers: Charge only with equipment designed for sodium-ion batteries with the correct voltage (e.g., ≤ 3.95V per cell) and current limits.
Temperature Control: Do not charge outside the recommended temperature range (-20°C to +60°C, ideally 0°C to +45°C). Charging below -20°C can cause permanent damage.
Voltage/Current Limits: Do not exceed the maximum charge voltage or current.

Discharging

Voltage Limit: Do not discharge the battery below the recommended cut-off voltage (≥1.8V). Deep discharge can irreversibly damage the battery.
Current Limit: Do not exceed the maximum continuous discharge current.
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 (longer than one month), store the battery at a state of charge between 30% and 50% (approx. 3.4V - 3.6V).
Storage Environment: Store in a cool, dry place away from direct sunlight, heat sources, and moisture. The recommended storage temperature is typically -20°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.
