Lithium-ion batteries power our modern electronics, from smartphones to wireless earbuds, but their lifespan remains a challenge, especially under real-world conditions. While traditional lab tests provide insights into battery degradation, they often fail to capture how batteries behave inside actual devices, where they are exposed to varying temperatures, mechanical stresses, and different usage patterns.

Widespread applications for electrochemical energy storage based on lithium-ion batteries now demand higher performance in terms of energy and power density, coupled with robust cycle life.  Despite major advancements in lithium-ion batteries, a shortage of precious metals, such as cobalt, which is typically used in the cathode in lithium-ion batteries and is sourced from only a few countries globally, is predicted.
