Battery materials often consist of multi-component composites which are not homogeneous. To study the intrinsic properties of active components is very challenging for conventional electrochemical techniques.

Recently, the Mauzeroll lab investigated single particle aggregates of lithium iron phosphate by scanning micropipette contact method (SMCM). To extend the potential window they used the ionic liquid EMI TFSI. The technique proofed to yield reproducible results and the redox activity of single lithium iron phosphate particles could be measured.

Measuring currents on single particle aggregates down to the lower pA range is no problem for HEKA’s potentiostats and full software implementation makes it very easy to conduct SMCM experiments with ElProScan.
