Lithium Battery Storage Temperature

How to store batteries.

Lithium battery storage temperature.

Lithium ion batteries handle cold temperatures down. Lithium battery storage buildings with climate control are ideal for storing bulk quantities of li ion batteries at specific temperatures to ensure a safe. But that s not the case across the board so before storing lithium batteries thoroughly read labels on proper storage. Learn about storage temperatures and state of charge conditions.

A prototype li ion battery was developed by akira yoshino in 1985 based on earlier research by john goodenough m. Place a lithium ion battery in a climate controlled storage structure such as a shed or garage or take it inside your house for storage. These act as an early warning system for detection of thermal events in the cabinet interior. When operated or stored at temperatures above 60 c they age particularly quickly which is reflected in a prompt reduction in storage capacity.

While lithium ion batteries handle cold weather better than most battery chemistries temperatures too high or too low still compromise their ability to store and release energy. The extreme allowable temperature is 40 c to 50 c 40 c to 122 f for most chemistries. The recommended storage temperature range is 0 c to 30 c 32 f to 86 f. You can store a sealed lead acid battery for up to 2 years.

Failing to adhere to the recommended storage temperature can permanently damage the capacity of lithium ion batteries. The recommended storage temperature for most is 59 f 15 c. For storage of substances for which self ignition cannot entirely be ruled out e g. Lithium ion batteries temperature sensors are recommended for prevention.

For example a battery stored at 104 f 40 c for 1 year will only retain 85 of its original capacity while a battery stored at 77 f 25 c will retain 96 of its capacity. Conventional lithium ion battery cells only guarantee a high life expectancy in a very limited temperature range typically 0 40 c. Charged to 40 capacity loss. At this storage temperature range the battery will require a maintenance charge within a nine 9 to twelve 12 month period.

The below graph data comes from here outlines the ideal charge point and temperature for battery storage. Cold temperature increases the internal resistance and lowers the capacity. The storage temperature range for lithium ion cells and batteries is 20 c to 60 c 4 f to 140 f. The recommended storage temperature for most batteries is 15 c 59 f.
