Components for improved lithium battery systems: pressure regulation and fluid control

An essential characteristic of battery systems used in automotive and industrial applications is their long-term durability. One thing that has to be prevented is the occurrence of free fluids inside the battery system. This can be caused by leakage and by the “breathing interaction” between the battery housing and its surrounding environment – leading to condensation of air humidity forming inside the battery housing. This article describes approaches to pressure regulation of battery systems and to reducing and/or preventing fluids from occurring inside them.
