Lithium-ion Batteries Reconstructing a 3-D Image Using Neutron Computed Tomography
- 14 Downloads
The tomographic reconstruction of a lithium-ion battery from radiographic 2-D projections enables the precise analysis of internal battery parameters. The paper from MathWorks, German Patent Office, and FRM-II shows how the method can be used as a highly effective diagnostic tool: for in-situ aging diagnosis, which can be implemented for quality control in battery production.

Unlike nickel-cadmium (NiCd), nickel-metal hydride (NiMH) or lead-acid batteries, lithium-ion (Li-ion) batteries offer numerous advantages for storing electrochemical energy, including high energy and power densities, a weak memory effect, and slow self-discharge. These advantages make Li-ion batteries ideal for a wide variety of applications: portable tools and consumer electronics, hybrid and electric vehicles (from bicycles to container ships) or stationary storage for...
