摘要： A set-up for detecting an electrolyte leakage from an electrochemical cell, the set-up comprising:
- at least one electrochemical cell (2) containing an electrolyte,
- an electrically conductive component (3) placed with respect to said at least one electrochemical cell so that it is exposed to the electrolyte in case of an electrolyte leakage,
- a complex impedance measuring device (4, 5, 6) configured to measure the complex impedance of the electrically conductive component.
This set-up is useful for distinguishing whether there is an electrolyte leakage or whether any other fully or partially conductive liquid has condensed at the surface of the electrically conductive component.

摘要： The present invention relates to an all-solid-state battery including a thin film current collector and a method of manufacturing the same, and more particularly to a current collector having a thickness of less than 5 µm, which is thermally treated together with a solid electrolyte, whereby interfacial resistance between the current collector and the solid electrolyte is reduced, and therefore the overall size of the all-solid-state battery is reduced, and a method of manufacturing the same.

摘要： The testing method disclosed herein tests the thermal propagation occurred in the assembled battery. The testing method includes: calculating a reference voltage value Vs based on the voltages of the single batteries; testing thermal propagation based on the reference voltage value Vs and the voltages of the single batteries. In the testing, if a first voltage difference (V s - V 1 ) between a voltage Vi of a predetermined first single battery and the reference voltage value Vs is a first threshold value V T1 or more, and a second voltage difference (Vs - V 2 ) between a voltage V 2 of a second single battery adjacent to the first single battery and the reference voltage value Vs is a second threshold value V T2 or more, it is determined that the thermal propagation is occurring. According to such a testing method, the thermal propagation occurred can be detected accurately in an early stage.

摘要： Eine Energiespeichervorrichtung (100) umfasst einen Verbund (101) aus einer schichtförmigen positiven Elektrode (102), einer schichtförmigen negativen Elektrode (103) und einem schichtförmigen Separator (104), der zwischen der schichtförmigen positiven Elektrode (102) und der schichtförmigen negativen Elektrode (103) angeordnet ist, ein Gehäuse (105) aus einem ersten Gehäuseteil (106) und einem zweiten Gehäuseteil (107) und einen Elektrolyten, der beim Laden und/oder Entladen der Energiespeichervorrichtung (100) einen lonenstrom zwischen den Elektroden (102, 103) gewährleistet. Die Elektroden (102, 103) umfassen jeweils eine elektrochemische Aktivkomponente. Der schichtförmige Separator (104) umfasst ein poröses Flächengebilde (105). Die Energiespeichervorrichtung (100) zeichnet sich dadurch aus, dass das poröse Flächengebilde (105) einen zentralen Bereich (105a) umfasst, in dem seine Poren mit dem Elektrolyten befüllt sind, sowie einen streifenförmigen, den zentralen Bereich (105a) umschließenden Randbereich (105b), in dem die Poren des porösen Flächengebildes (105) nicht mit dem Elektrolyten befüllt sind. Das erste Gehäuseteil (106) und das zweite Gehäuseteil (107) sind über einen umlaufenden Siegelrahmen (108), der aus einem Siegelmittel gebildet ist, das in dem Randbereich (105b) auf das poröse Flächengebilde (105) aufgebracht wurde, miteinander verbunden. Zur Herstellung der Energiespeichervorrichtung (100) wird durch Aufbringen des Siegelmittels in dem streifenförmigen Randbereich (105b) eine Separator-Siegetrahmen-Einheit gebildet, die zur Bildung des Verbundes (101) mit der schichtförmigen positiven Elektrode (102) und der schichtförmigen negativen Elektrode (103) kombiniert wird.
