Reliable Power Solutions for Harsh Environments

High-Temperature-Resistant Coin-Type Lithium Primary Batteries

Coin-type batteries are widely used on printed circuit boards (PCBs) in servers and in automotive ADAS/AD systems to retain time data when the main power supply is turned off.

As AI adoption accelerates, increasing processing loads on PCBs, making heat generation a critical challenge.

As a result, coin batteries mounted on these boards must offer high reliability, maintaining stable performance over long periods, even under elevated temperatures.

Coin-type batteries play a critical role in maintaining time data on PCBs when the main power supply is interrupted.

With the rapid expansion of AI, processing loads on PCBs have significantly increased, leading to higher operating temperatures.

To address this challenge, batteries used in these environments must deliver long-term reliability and stable performance, even under high-temperature conditions.

Features

Standard CR coin-type batteries show a rapid increase in internal resistance and a sharp drop in voltage within tens of hours of storage at 125°C, making continued use difficult. In contrast, our high-temperature resistant model maintains stable operation for over 200 hours while minimizing changes in resistance and voltage.
Typical CR coin-type batteries degrade under high-temperature conditions due to gas generation within the battery. Our high-temperature resistant technology suppresses gas generation within the battery, ensuring stable operation even in harsh environments.
Designed for communication applications, our battery provides excellent pulse discharge performance.

With its unique anode composition,our high-temperature resistant battery maintains a stable voltage equivalent to room temperature even at 80% depth of discharge, outperforming conventional models.
