New cathode and anode materials for lithium ion batteries (LiB) are often tested for their electrochemical performance using lithium metal as the counter electrode. In laboratory language, these configurations are... read more →
This application note is supposed to be the first in a series dealing with the electrochemical testing of materials for lithium-ion batteries (LiB) using the PAT system from EL-CELL. More... read more →
Sometimes a finger-shaped reference electrode can be better than our standard ring-shaped reference electrode. The finger reference measures the electrical potential in the middle of the stack instead of at... read more →
Very often, Li-ion test cells are characterized in two separate experiments: first, constant current charge/discharge cycles are applied in order to learn about the direct current (dc) behavior of the... read more →
The anode material in almost all of today’s secondary lithium-ion batteries is graphite. In order to boost the energy density, we would love to replace the graphite by lithium... read more →
In a previous application note named “1001 reasons for using a reference electrode” we tried to convince you of the advantages of three-electrode cells with reference electrode over so-called half... read more →
The FS-5P is a double-layered separator comprised of a 180 µm thick nonvowen PP cloth (Freudenberg FS 2226 E) and a 38 µm thick microporous UHMW-PE membrane (Lydall Solupor 5P09B).... read more →
Former test setup In a previous report, we have used the ECC-Opto-Std test cell to visualize the electrochemical lithiation of a free-standing graphite electrode sandwiched with a lithium metal counter... read more →
There are many good reasons for using a reference electrode. In this note we report a few of them using the example of a lithium-ion battery comprising a lithium cobalt... read more →
Because of the outstanding reliability of the built-in lithium metal reference electrode, the PAT-Cell is the ideal test cell for long-term 3-electrode experiments on Li-ion battery systems. The BioLogic VSP potentiostat,... read more →
