Many familiar with the construction of a prismatic lithium-ion battery will say that it breathes. Charging and discharging causes changes in temperature, electrochemistry, and the mechanics of the internal components are affected by changes in pressure. Too much or too little stack pressure can affect the long-term performance and safety of a prismatic cell battery after multiple charge & discharge cycles. 

With the help of pressure mapping technology, which utilizes ultra-thin and flexible pressure sensors to conform within and around tight spaces, battery designers have a useful method to verify battery housing in multi-day charge/discharge cycle evaluation.
