Li metal or Li ion – This is the question

  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 metal. Many people work on this goal. Unfortunately, the lithium metal anode tends to form dendrites during electrochemical plating, eventually... read more →

Lithium metal dendrites: Pictures speak louder than words

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 cells with lithium metal counter electrode. We claimed: “The large overvoltage at the lithium metal CE, the chemical reactivity of... read more →

New separator for PAT insulation sleeves

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). We offer PAT insulation sleeves with this FS-5P separator, either with or without a lithium reference. When built into the... read more →

1001 reasons for using a reference electrode

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 oxide (LCO) cathode and a graphite anode. All measurements were performed with a PAT-Cell, docked into a PAT-Stand-16 (both EL-Cell).... read more →

Featured Product: PAT-Cell in PAT-Stand-1 with Bio-Logic VSP Potentiostat

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, on the other hand, is a perfect match for controlling this type of experiment, as it is capable of monitoring... read more →
