(summary of the disclosure)

The battery that one technical solution of the disclosure is related to has monocell, electrode collector, to electrode collector and sealing Part, the monocell include electrode layer, it is opposite with the electrode layer to electrode layer and be configured at the electrode layer with it is described To the solid electrolyte layer between electrode layer, the electrode collector is contacted with the electrode layer, it is described to electrode collector with Described to contact to electrode layer, the sealing element is configured at the electrode collector and described between electrode collector.The list Battery is configured at the electrode collector and described between electrode collector.The sealing element includes to the solid electrolyte Layer at least one protrusion outstanding, at least part of at least one protrusion connect with the solid electrolyte layer Touching.

Thereby, it is possible to improve the mechanical strength of battery.Specifically, being supported due to the protrusion by sealing element solid Body electrolyte layer, therefore the external force relative to situation about pressing powered electrode on each collector etc., are able to suppress solid electricity Solve the avalanche of matter layer.Therefore, the breakage risk that can reduce the generating element as monocell, can obtain the electricity of high reliablity Contact.

For example, in the case where a part to solid electrolyte layer applies external force, due to the protruding portion by sealing element Divide to support solid electrolyte layer, therefore is able to suppress the avalanche of solid electrolyte layer.For example, even if in all-solid-state battery or Electrode layer and in the battery for not having partition between electrode layer, also can reduce due to electrode collector with to electrode current collection The direct contact or the avalanche of solid electrolyte layer of body and make electrode layer and the risk to electrode layer short circuit.

In addition, since sealing element is set to electrode collector and between electrode collector, can reduce electrode collection Electric body and a possibility that electrode collector is contacted.I.e., can by sealing element by electrode collector with to electrode collector it Between distance maintaining more than certain distance (such as more than the thickness of sealing element), therefore be able to suppress electrode collector with to electricity Electrode current collector is closer to each other.

In addition, for example can be set at least one described protrusion and the electrode layer and described do not connect to electrode layer Touching.

With electrode layer or the risk that electrode layer chemically reacts sufficiently is reduced due to sealing element as a result, it can Expand the range of choice that can be used as the material that sealing element utilizes.

In addition, for example described sealing element can with the electrode collector and described electrode collector is contacted.

Thereby, it is possible to by electrode collector and be better maintained at one to the interval between electrode collector by sealing element More than set a distance (such as more than the thickness of sealing element).Therefore, electrode collector can preferably be inhibited and to electrode collector It is close to each other.Thereby, it is possible to further decrease due to electrode collector with electrode collector is directly contacted to making electrode layer With the risk for electrode layer occurring short circuit.

In addition, for example can be set at least one described protrusion includes multiple protruding portion point.

Thereby, it is possible to support solid electrolyte in many places by multiple protruding portion point, therefore relative to pressing powered electrode The case where etc. external force, can preferably inhibit the avalanche of solid electrolyte layer.Therefore, the power generation as monocell can be reduced The breakage risk of element obtains the electrical contact of high reliablity.

The external force of as a result, relative to pressing powered electrode the case where etc., is able to suppress the solid for being particularly susceptible to damage The avalanche in the corner of electrolyte layer.Therefore, the breakage risk that can reduce generating element obtains the electrical contact of high reliablity.Separately Outside, in the case where the corner of solid electrolyte layer is respectively equipped with protrusion, using each that multiple protruding portion is divided as top The polygonal of point is arranged to built-in power generation element.Thereby, it is possible to improve the Mechanical Reliability of battery entirety.

In addition, for example can be set in the battery from thickness direction, at least one described protrusion has The elongate in shape configured along the periphery of the solid electrolyte layer.

The contact area of protrusion and solid electrolyte layer increases as a result, therefore the feelings relative to pressing powered electrode The external force of condition etc. can preferably inhibit the avalanche of solid electrolyte layer.Therefore, the generating element as monocell can be reduced Breakage risk, obtain the electrical contact of high reliablity.

In addition, for example can be set in the battery from thickness direction, at least one described protrusion along The entire periphery of the solid electrolyte layer continuously configures.

The external force of as a result, relative to pressing powered electrode the case where etc., it is whole due to protrusion and solid electrolyte layer A periphery contact, therefore the avalanche of solid electrolyte layer can be adequately suppressed.Therefore, the power generation as monocell can be reduced The breakage risk of element obtains the electrical contact of high reliablity.

In addition, for example can be set to the solid electrolyte layer includes recess portion, at least one described protrusion is at least A part is contacted with the solid electrolyte layer within the recess.

As a result, since protrusion is located at the recess portion being arranged on the solid electrolyte, protrusion can be made more preferable Support solid electrolyte layer in ground.Therefore, the breakage risk that can reduce the generating element as monocell, obtains high reliablity Electrical contact.

In addition, for example can be set to the solid electrolyte layer comprising electrode side electrolyte layer and to electrode side electrolyte Layer, the electrode side electrolyte layer is contacted with the electrode layer, described to electrode side electrolyte layer and the electrode side electrolyte Layer and it is described electrode layer is contacted, at least one described protrusion and the electrode side electrolyte layer and described to electrode side electricity Solve the interfacial contact of matter layer.

In addition, for example can be set in the battery from thickness direction, the electrode collector include not with institute The 1st region of electrode layer overlapping is stated, the 1st region includes at least part of the periphery of the electrode collector, described right Electrode collector includes not with 2nd region Chong Die to electrode layer, and the 2nd region includes described to electrode collector At least part of periphery, the sealing element are Chong Die with the 1st region and the 2nd region.

Thereby, it is possible to improve sealing element and electrode collector and to the respective zygosity of electrode collector, can be improved every The electrode collector of sealing element with to the intensity of the bonding part of electrode collector.Therefore, electrode collection can be further decreased Electric body and a possibility that electrode collector is contacted.

In addition, for example can be set to the sealing element includes the 1st sealing element and the 2nd sealing element, the 1st sealing element includes 1st material, the 2nd sealing element include 2nd material different from the 1st material, and the 1st sealing element is located at than described the Closer to the position of the electrode collector, the 2nd sealing element is located at than the 1st sealing element closer to described 2 sealing elements To the position of electrode collector.

As a result, from the viewpoints such as reactivity or mechanical property, it can be selected as the material of the sealing element of side of the positive electrode respectively Expect the most suitable material of the material of most suitable material and the sealing element as negative side.Thereby, it is possible to further increase electricity The reliability in pond.
