Dendrite Growth Simulation Framework for the Design of Battery Materials

Current models and numerical approaches of battery technology are one dimensional in nature and can simulate time scales from nanoseconds to microseconds of electrodeposition and length scales from angstrom to nanometer. They are not practical to describe physical systems that occur in a larger time range, such as the seconds to hours and days range, or in a larger length scale range such as the nanometer to tens of micrometers range.

Researchers at Purdue University have developed a new framework to describe the time-dependent, spatially resolved electrodeposition of materials, specifically to describe the localized lithium electrodeposition in rechargeable battery anodes for both electrochemically inert and active substrates. This technology describes the dendrite growth process in battery materials using larger, more practical times and length scales. In addition, it allows for spatially resolving the morphology of the dendrites and its interactions with the surrounding materials and phases.

Advantages:

-Describes the dendrite growth process in battery materials using the larger, practical times and length scales

-Spatially resolves the morphology of the dendrites and its interactions with the surrounding materials and phases

Potential Applications:

-Battery testing and design

-Battery manufacturers
