50Ah 2.86V Sodium-Ion Prismatic Cell | ATOMFAIR

COMMERCIAL GRADE · PRODUCTION

Product Overview

The ATOMFAIR^® 50Ah sodium-ion prismatic cell delivers high power and long life for advanced energy storage systems. With a nominal capacity of 50Ah, average operating voltage of 2.86V, and charge voltage of 3.45V, this cell supports standard 0.5C charge/discharge, maximum continuous discharge up to 8C, and pulse discharge capability of 10C for 30 seconds at 100% SOC (25°C). Engineered for extreme climates, it operates across a wide temperature range: charging from 0°C to 55°C and discharging from -40°C to 60°C. The cell features low internal resistance (≤0.5mΩ) and compact dimensions (50.1×160×118.5 mm), making it ideal for high-rate applications such as low-speed EVs, telecom backup, and grid-scale storage while maintaining intrinsic sodium-ion safety and cost advantages.

Key Features & Advantages

Cost-Effective Solution: Leveraging abundant sodium resources and simplified manufacturing, our cell offers significantly lower cost compared to lithium-ion alternatives, making energy storage more affordable.
High Power Capability: Supports up to 8C continuous discharge and 10C pulse discharge (30s), ideal for high-rate applications such as low-speed EVs, power tools, and UPS systems.
Wide Operating Temperature: Discharge from -40°C to 60°C and charge from 0°C to 55°C, ensuring reliable performance in extreme climates without auxiliary heating.
Low Internal Resistance: ≤0.5mΩ impedance minimizes energy loss and heat generation, enhancing overall system efficiency.
High Safety & Reliability: Sodium-ion chemistry provides exceptional thermal stability and intrinsic safety, meeting stringent international standards.
Compact & Lightweight: Weighing only 1.8kg with optimized dimensions (50.1×160×118.5 mm), enabling flexible integration into space-constrained systems.

APPLICATION SCOPE: Low-speed electric vehicles (e-rickshaws, forklifts, golf carts), telecom backup power, grid-scale energy storage, commercial & industrial ESS, renewable integration (solar/wind), peak shaving, load leveling, and high-rate UPS systems.

PACKAGING: Humidity-controlled vacuum sealed packaging, individual cell isolation in anti-static foam lined cartons. Custom palletized packaging for bulk orders available upon request. Each cell includes terminal covers and desiccant bag.

IMPORTANT NOTICE: Always pair with a dedicated BMS supporting appropriate sodium-ion voltage windows (1.5V–3.45V per cell). Avoid over-discharge below 1.5V and over-charge above 3.45V. Store cells at recommended temperature 15°C–35°C. Sodium-ion cells are compatible with standard lithium-ion assembly equipment; however, use only manufacturer-approved cell holders and busbars. Dispose of cells following local regulations for sodium-based batteries.
