Cylindrical carbon pack battery (energy type)
Carbon pack battery is one of the two cylindrical lithium manganese dioxide batteries, which has the highest specific energy due to the use of thick electrodes and the largest amount of active material. However, due to the limitation of electrode surface area, the discharge capacity of the battery is also limited, making it only suitable for low current applications. There is a safety valve on the battery cover, which can release the pressure inside the battery in case of mechanical or electrical abuse. In addition to rolled edge sealed batteries, welded sealed batteries can also be made, which have a storage life of 10 years and can be used for storage backup power and other low current applications. This is an energy type, and SE is added after the typical energy type lithium manganese dioxide battery model.
