1. Introduction

Cold chain monitoring devices are critical in maintaining the integrity of temperature-sensitive goods such as vaccines, pharmaceuticals, perishable foods, and biological samples. Reliable power supply ensures uninterrupted data collection and real-time alerts during transport and storage. However, traditional batteries often underperform in low-temperature environments, leading to shortened lifespan and possible data loss.

PKNERGY provides semi-solid lithium battery solutions engineered specifically for cold chain devices, combining high energy density, extended lifespan, and stable performance in extreme conditions.

2. Application Background

Cold chain monitoring devices are used in refrigerated trucks, storage facilities, and laboratories. These systems demand compact, lightweight, and reliable batteries that can operate continuously at sub-zero temperatures.

• Low-temperature performance: Reliable operation down to –20°C
• Long cycle life: Continuous monitoring for long shipping or storage periods
• Compact design: Slim form factor for portable data loggers
• Safety & compliance: International certifications for cold environments
