Lithium Polymer (LiPo) batteries are widely preferred in medical devices due to their unique combination of safety, performance, and design flexibility. The most common types include:

1. Standard LiPo Battery

Used in portable medical devices like infusion pumps, portable monitors, and diagnostic tools.

Typical capacities: 500mAh to 10,000mAh.

Voltage: 3.7V (single-cell) or 7.4V/11.1V (multi-cell).

 

2. Thin/Flat LiPo Battery

Designed for wearable medical devices (e.g., continuous glucose monitors, ECG patches).

Ultra-thin profiles (as low as 1mm thickness).

Custom shapes to fit compact spaces.

 

3. High-Rate Discharge LiPo Battery

Used in defibrillators, surgical tools, and emergency medical devices.

Support high current bursts (e.g., 5C–10C discharge rates).

Common Medical Applications:

Device Type	Why LiPo is Used
Infusion Pumps	Long runtime, lightweight
Portable Ventilators	High energy density, fast recharge
Wearable Monitors	Thin, flexible design
Surgical Tools	High power bursts
Implantables	Biocompatible, long lifespan

 

LiPo batteries dominate medical devices because they offer the best balance of power, safety, and adaptability. Manufacturers further enhance them with medical-grade protections to meet strict regulatory requirements.
