Revealing the Distribution of Lithium with the Cipher System

Cipher® is the first and only device that quantifies lithium dispersion in scanning electron microscopes and dual beam instruments. This system is able to determine the lithium concentration in metallic alloys, compounds, and complex metal oxides down to single-digit weight percentages using the revolutionary lithium by composition by difference method (Li-CDM), speeding up the development of renewable energy materials and aerospace alloys.


  • Reveals previously unknown lithium distribution at the microscale in a wide range of materials.
  • Determines the charge status of lithium nickel manganese cobalt oxide (NMC) and lithium iron phosphate (LFP) oxide particles used as cathodes in lithium-ion batteries.
  • Provides quantitative lithium analysis with a tenfold increase in the minimal detection limit.
Determining Lithium Content by the Composition by Difference Method

Determining Lithium Content by the Composition by Difference Method. Lithium (Li)-ion batteries have been adopted for a wide range of energy storage applications due to their outstanding energy density and low mass compared to other technologies. However, there remains considerable scope for energy capacity and efficiency improvements by optimizing devices and materials used in their construction. In particular, microstructural and compositional analysis has proven challenging at the micro- and nano-scales with structure evolution and degradation mechanisms due to a lack of understanding at these length scales.
