Preparation of Graphene Liquid Cells for the Observation of Lithium-ion Battery Material

This graphene liquid cell enables transmission electron microscopy for these dynamics in a liquid electrolyte. Such dynamics can provide rich information of the working mechanisms of Lithium-ion batteries and contributes to designing advanced battery devices. The advantages of graphene liquid cell is that it allows TEM imaging in liquid electrolyte providing good spatial resolution and high imaging contrast.

In addition to a superior quality of the image, it can also provide information of various morphological phase and interfacial transitions. With only a written protocol, it is difficult to follow this method because many technical steps are conducted by hand. A lot of the skills require accuracy and precision, where the use of patience is highly recommended.
