In recent years, the combination of experiments and modelling has shown to be a promising alternative to only experimental work . Some researchers have focused on reducing the number of experiments required to understand the relationship between battery performance and the manufacturing process by using models at different scales , .
Why study Lithium-ion batteries? Lithium ion batteries are a critical component of modern life, relied on by billions of people to power devices from the smallest health implants to large trucks, and even planes. They can be found in our phones, power tools, laptops, cameras, cars, aircraft, tablets, and the electric grid, to name a few.
The batteries can be charged and discharged. This relies on the movement of lithium ions in the electrolyte through a semipermeable barrier and electrons in an external circuit. Over time, the battery performance decreases from repeated insertion of lithium ions into the graphite structure.
