Solid state battery (sample by Prof. Hayashi, Osaka Prefecture University)
The newly released laminated cell can be used for analysis of double-side-coated electrodes and Stacked battery.
ECCS B320 provides high-magnification color images and supports the analysis of electrochemical reactions of an active material.
ECCS B320 shows dendrites being formed by current concentration as a result of uneven reactions during the charging process.
ECCS B320 visualizes the volumetric expansion of active materials and enables you to measure the thickness of active materials for analysis and comparison with the battery's charge/discharge curves.
ECCS B320 shows dendrites being formed while a battery is overcharged at high rate. Once the charging stops, the dendrites start to shrink and lithium ions are dispersed from dendrites to charge the anode.
ECCS can capture small changes in brightness during charge/discharge and enables you to make quantitative analysis of the reaction distribution in the cross section of cathodes in the same way you do for anodes.
ECCS can capture very small expansions and contractions in cathodes, which usually show only a slight dynamic change.
ECCS enables the observation of outgassing during charge/discharge.
In-situ gas analysis is also available when a gas analysis cell is used (together with a gas chromatograph).
