Lithium Ion Battery Storage Temperature

Estimated recoverable capacity when storing a battery for one year elevated temperature hastens permanent capacity loss.

Lithium ion battery storage temperature.

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. Tips for lithium ion battery storage. We recommend that the batteries be charged about once per year to prevent overdischarge. Lithium ion batteries temperature sensors are recommended for prevention.

A prototype li ion battery was developed by akira yoshino in 1985 based on earlier research by john goodenough m. Temperature is vital for understanding how to store lithium batteries. Charged to 40 capacity loss. But that s not the case across the board so before storing lithium batteries thoroughly read labels on proper storage.

The below graph data comes from here outlines the ideal charge point and temperature for battery storage. Stanley whittingham rachid. These act as an early warning system for detection of thermal events in the cabinet interior. The storage temperature range for lithium ion cells and batteries is 20 c to 60 c 4 f to 140 f.

At this storage temperature range the battery will require a maintenance charge within a nine 9 to twelve 12 month period. The recommended storage temperature for most is 59 f 15 c. Batteries are often exposed to unfavorable temperatures and leaving a mobile phone or camera on the dashboard of a car or in the hot sun are such examples. Test data confirms that storage of lithium ion batteries is best if the cell is partially discharged.

Panasonic lithium ion battery storage. A lithium ion battery or li ion battery abbreviated as lib is a type of rechargeable battery lithium ion batteries are commonly used for portable electronics and electric vehicles and are growing in popularity for military and aerospace applications. When operated or stored at temperatures above 60 c they age particularly quickly which is reflected in a prompt reduction in storage capacity. A detailed maintenance charge.

Failing to adhere to the recommended storage temperature can permanently damage the capacity of lithium ion batteries. For storage of substances for which self ignition cannot entirely be ruled out e g. Storing a lithium ion battery. Conventional lithium ion battery cells only guarantee a high life expectancy in a very limited temperature range typically 0 40 c.

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. The batteries should be stored at room temperature charged to about 30 to 50 of capacity. The recommended storage temperature range is 0 c to 30 c 32 f to 86 f.
