Nanoindentation is a well-established technique to measure a variety of mechanical properties of materials at the local positions. Currently there are many challenges when it comes to performing this method. It requires the stability of the testing environment, control of sample sizes, and control of the geometry of the test which are all difficult variables to control. Operando Indentation requires a couple of extra steps which makes it even more difficult to perform. There is a need for a new technology that allows for easier performance of the operando indentation method.

Researchers at Purdue University have developed a new technology that allows the operando indentation to be performed easier. This new technology integrates a fluid cell. This fluid cell is inert to the liquid electrode which means the testing can be done in a liquid environment. This new technology also allows testing to be done in an open configuration. All of these things lets the testing be done during real time charging and discharging. This new technology opens the door for how operando indentation can be performed when testing on batteries.

-Measure behavior in real time charging and discharging
-Characterize materials in open configuration
-Characterize materials in liquid environment

Potential Applications:
-Operando indentation
