CR Cylindrical Type
Cylindrical Lithium Manganese Dioxide Battery



Maxell CR (cylindrical lithium manganese dioxide) batteries are available only for equipment manufacturers as a built-in part. Therefore, Maxell does not supply these batteries for replacement directly to users of equipment with these batteries. When built-in CR batteries need to be replaced, please contact your equipment manufacturer. If you are planning to use Maxell CR batteries in your equipment as a built-in part, please contact Maxell.

Product Safety Data Sheet Down load(44kb)

 

 

 

OVERVIEW

The cylindrical lithium manganese dioxide battery (CR battery) features high capacity and excellent load characteristics due to Maxell’s unique winding method and improved electrical-conductivity structures. Because of its high-reliability, this battery is ideal for industrial use in, for example, security equipment and the power source of electronic meters.

 

 

 

PRINCIPLE AND REACTIONS

The cylindrical lithium manganese dioxide battery uses manganese dioxide (MnO2) as its positive active material and lithium (Li) as its negative active material.
 

Battery Reactions

Positive reaction: MnIVO2+Li++e-     MnIIIO2 (Li+)
Negative reaction:    Li   Li++e-
Total reaction: MnIVO2+Li     MnIIIO2 (Li+)

 

 

 

 

CONSTRUCTION

 

 

 

 

FEATURES

•
High capacity batteries
 
Maxell’s unique winding method and effective utilization of positive and negative electrodes realize a high capacity
•
Low self-discharge rate and long battery life
 
A laser seal structure ensures air tightness. Minimized electrode surface areas reduce the self-discharge rate.

Superior storage characteristics
 

The optimization of positive materials and employment of a high-reliability sealing structure stabilize pulse discharge characteristics over a wide usable temperature range after long time storage or discharge.

 

 

 

 

APPLICATION

Security Devices
Home Fire/Smoke Alarms
Eletronic Meters(Water, Gas, Electricity)

Memory Backup Power
