At CamVolt, we believe that careful control over pressure is the missing puzzle piece needed to take battery research and development to the next level. Our products are designed to enable battery researchers, materials scientists, and engineers to elevate their battery performance and design batteries that achieve higher capacity, longer cycle life, and higher energy density.
Check out a blurb from our white paper explaining why pressure’s so important below.
Why Pressure Matters
By Jensen Rocha, Heng Wang, Dr. Joe Stallard, Professor Michael DeVolder
”Rechargeable batteries, including lithium-ion batteries (LIBs) and lithium-metal batteries (LMBs) have a critical role in the renewable energy transition as energy storage vectors for grid storage, transportation, and other difficult to decarbonize sectors1. This diverse set of applications makes it important that batteries have key properties such as high specific power, high capacity, and long cycle life2.
However, LIBs and LMBs are complex, heterogeneous systems, where material, mechanical, and electrochemical properties are tightly interlinked. As a result, achieving key performance metrics like high power, capacity, and long cycle life often requires careful protocol optimization, making it critical to control external conditions in laboratory testing to ensure industrial scalability. One critical external property that has been historically difficult to control is the external stack pressure.
Applied stack pressure, which is integrated into industrial battery applications through battery module and pack design has been shown to impact the specific power, capacity, and cycle life of batteries, varying with material choice. The value of applied stack pressure during both the formation and lifetime cycling of batteries is important to optimizing LIB or LMB performance.”
