High-Reliability Polymer Li-ion Cell

For Hazardous Area Equipment & Intrinsically Safe Device Integration

The OiD124345-1900 is a premium-grade polymer lithium-ion battery cell engineered as a core power component for manufacturers developing equipment intended for use in hazardous or potentially explosive environments.

Produced by Shenzhen Jianheng Technology Co., Ltd, this cell is designed to deliver stable electrical performance, predictable energy behavior, and robust safety characteristics, supporting system-level explosion protection and intrinsically safe (IS) design concepts.

Engineered for System-Level Safety Integration

In hazardous area applications, explosion protection is achieved at the complete device level, not by individual components alone.
The role of the battery cell is to provide electrical stability, controlled energy release, and consistent behavior under stress, forming a reliable foundation for safety engineering.

The OiD124345-1900 supports this approach through:

• Stable nominal voltage (3.7 V) with a flat discharge profile

• Limited continuous charge and discharge capability (0.5C), facilitating current control

• Low internal resistance to minimize heat generation

• Strict factory voltage control to ensure predictable integration behavior

Important Notice

This lithium-ion cell is a component.
Final ATEX, IECEx, or other explosion protection certifications are obtained at the complete device level, through appropriate system design incorporating certified protective circuits, current limiting, thermal management, and safety barriers.

Shenzhen Jianheng Technology provides detailed technical data and test information to support customers’ safety engineering and certification processes.

Key Electrical Specifications

Operating Temperature Characteristics

Charging below 0°C is not permitted due to lithium plating risk and reduced cycle life.

Rigorous Cell-Level Safety & Reliability Testing

The following tests demonstrate the inherent robustness of the cell, providing a reliable basis for device-level explosion protection design:

• Overcharge resistance (no fire, no explosion)

• Over-discharge tolerance

• Thermal cycling (-40°C to 75°C)

• Mechanical shock and vibration

• Drop test (1.0 m)

• High temperature & high humidity exposure

• Low pressure (aviation transport conditions)

These results confirm the cell’s suitability as a high-reliability power component in safety-critical designs.

Typical Integration Scenarios

(For Certified Equipment)

• Portable gas detectors and air quality monitors
