SIHC0412-3R0-2 Ultra-Compact Sodium Ion Battery (3.0V, 2mAh)

Product Overview

The SIHC0412-3R0-2 is an ultra-compact, 3.0V 2mAh sodium-ion micro-power cell engineered for demanding applications that require high-rate charge/discharge capabilities, an extended operating temperature range, and uncompromising safety. Unlike traditional lithium-ion chemistries, this sodium-based cell supports safe 0V transportation, significantly reducing shipping risks and regulatory restrictions. Characterized by an exceptionally low risk of thermal runaway, rupture, or ignition, it serves as an ideal, reliable power solution for next-generation IoT devices, smart wearables, medical sensors, and critical backup systems.

Product Technical Index

Advanced Performance & Environmental Characteristics

• Extreme Temperature Resilience: Engineered to function reliably from -40°C to 70°C. At a freezing -20°C, the cell retains ≥ 60% of its initial capacity with internal resistance shifting no more than 10 times its nominal value. At an elevated +65°C, capacitance fluctuations remain securely within ± 10%, making it exceptional for outdoor tracking and cold-chain monitoring.
• High Humidity & Long-Term Storage Stability: Under high-temperature and high-humidity testing, the cell maintains ≥ 70% of its initial capacitance. For long-term shelf storage under recommended conditions, it preserves ≥ 90% of its initial performance metrics.
• Extended Floating Charge Endurance: Demonstrates outstanding durability under continuous float-voltage conditions, maintaining ≥ 70% capacitance and keeping internal resistance within twice its initial limits

Technical information

Temperature Performance

At -20°C, capacitance retention is ≥60% of the initial value and internal resistance ≤10 times the initial specified value. At +65°C, capacitance change stays within ±10% of the initial value, and internal resistance remains within initial limits. The superior low-temperature performance (-40°C operation) makes it suitable for outdoor and cold chain applications.

Applications

This ultra-small SIHC energy solution is purpose-built for low-profile, space-constrained electronic designs, including:

• Smart Wearables & Healthcare: Wireless earbuds, hearing aids, smart rings, and clinical-grade medical patches.

• IoT & Smart Infrastructure: Miniature IoT sensor nodes, Bluetooth beacons, and electronic shelf labels (ESL).

• Industrial & Tracking: Extreme-temperature asset trackers, data loggers, and cold-chain environmental sensors.

• Memory Backup: Real-time clock (RTC) power backup and volatile memory safeguards for portable instruments.

Shipping, Packaging & Quality Assurance

• Pre-Shipment Voltage: Every unit undergoes rigorous quality screening and is dispatched at a stable storage voltage between 3.1V and 3.4V.

• Secure Packaging: All cells are packed securely in standard export-grade protective cartons to prevent physical damage or movement during transit.

• 0V Transport Advantage: Inherently safer than lithium chemistries, allowing for more flexible, low-risk global freight options.

Safety & Handling Precautions

To ensure maximum life cycle performance and operational safety, please adhere to the following handling guidelines:

• Voltage Limits: Always operate strictly within the defined voltage threshold (1.5V to 3.6V). Never overcharge beyond 3.65V.

• Polarity Management: Double-check electrical orientation before installation; avoiding reverse polarity is critical to preventing cell damage.

• Thermal Protection: Avoid exposing the cell to excessive thermal stress or prolonged high heat during the soldering and assembly process.

• Mechanical Integrity: Do not crush, puncture, disassemble, or subject the cells to direct external short-circuits.
