The synthesized aerogels were characterized by SEM, FTIR, Raman, XRD, XPS and BET. The electrochemical performances were determined by the cyclic voltammetry (CV), galvanotactic charge discharge (CD) and electrochemical impedance spectroscopic (EIS) measurements in two-electrode configurations.

KEMET KONNEKT™ package allows two to four ceramic capacitors to be stacked vertically or horizontally while retaining the integrity of the part. It uses transient liquid phase sintering (TLPS) technology to bond component terminations together. The KONNEKT™ U2J capacitors can be used in both orientations, thus minimizing the component footprint, while maximizing the bulk capacitance of a stacked MLCC with design flexibility in mind.
