Li-MnO2 Coin Cell

Introduction

Coin type Lithium  Manganese Dioxide Batteries are being used in a broad range of applications, from quarts watches and clocks, a backup power sources for memories requiring long-term reliability over 10 years to LoT equipment, and car keyless entry systems. Lithium metal, used for the anode in Coin Manganese Dioxide Lithium Batteries, has the largest electric capacity per unit weight (3.86 Ah/g) among all the materials usable for the anode. Thus, batteries with a high energy density can be produced. 

Features

  • Lightweight, High Voltage and High Energy Density

            The battery voltage is 3V, almost double that of normal alkaline batteries. This means that the number of batteries required for equipment can be halved for maximum space saving and weight reduction.

  • Excellent Discharge Characteristics

            Voltage characteristics remain stable even for a long period of discharge, greatly improving the reliability of equipment that uses the battery. Such equipment is also maintenance-free (battery replacement is seldom required).

  • Outstanding Temperature Characteristics

            Temperature range:  -20 to +70 degrees C ( high temp products can be extend to 125℃)

  • Excellent Long-Term Reliability 

            The annual self-discharge rate at room temperature and normal humidity is less than 1% of the nominal capacity.

 

Application

Toys, timer,  NB-LoT devices, wearable device, smart cards...
