目前有很多研究人员致力于新型电致变色器件以及装置的研究，例如CN111142303A公开了一种电致变色后视镜的改良结构，包含：一后视镜本体，该后视镜后侧面可供组设一显示器，后视镜本体包含：第一镜片组、第二镜片组、电致变色层、两个导电片、第一导电胶及第二导电胶，第一镜片组设有一第一镀层，第二镜片组设有一第二镀层，电致变色层包含有一封装框胶及一电致变色材料，该两个导电片一方为导电部，另一方为接点部，该两个导电片的导电部分别黏结于第二镜片组上，显示器与两个导电片的接点部焊结电性连接。CN213365229U公开了一种该电致变色器件，该电致变色器件包括第一导电层、电致变色层、第二导电层和引出电极，第一导电层、电致变色层及第二导电层层叠设置。第一导电层包括第一重叠区和第一错开区，第二导电层包括第二重叠区和第二错开区，第一错开区及第二错开区的至少部分位于电致变色层的同一侧，且第一导电层上设有第一汇流条，第二导电层上设有第二汇流条，引出电极分别与第一汇流条及第二汇流条导通。
在现有技术中，电致变色器件在进行电极引出时，通常分别将连接第一导电层的电极引线和连接第二导电层的电极引线从上下两片导电基底上分别引出，引出电极绑定时需要进行两次热压焊，例如焊接下片的电极引线后，再翻转电致变色器件，焊接上片的电极引线，工艺复杂，不利于自动化生产，生产效率低下，且不利于良率的提高。因此，本领域亟待开发一种引出方式更加简化、制备工艺简单的电致变色器件。
发明内容
本申请提供了一种电致变色器件及电子设备，所述电致变色器件仅需要一次热压焊即可完成电极引出过程，工艺简便，生产效率大大提高，且有利于改善产品良率。
第一方面，本申请提供了一种电致变色器件，所述电致变色器件包括依次叠加设置的第一导电基底层、电致变色层和第二导电基底层；其中，所述第一导电基底层包括依次叠加设置的第一透明导电层和第一基材层，所述第一透明导电层粘接在所述电致变色层的一侧；其中，所述第二导电基底层包括依次叠加设置的第二透明导电层和第二基材层，所述第二透明导电层粘接在所述电致变色层的另一侧；
所述第二透明导电层上设置隔断槽使其分为相互独立的第一导电区域和第二导电区域；所述第二导电区域上设置导通件，所述导通件将所述第一透明导电层与所述第二导电区域电连接。
本申请提供的电致变色器件中，通过在第二透明导电层上设置隔断槽，将第二透明导电 层分为相互隔断的两个区域，第一导电区域和第二导电区域不会互相电联通，进而通过导通件将第一透明导电层和第二导电区域电连接，从而实现同侧电极引出；用于连接第一透明导电层的电极引线和用于连接第二透明导电层的电极引线可以均从第二透明导电基底层引出，便于通过一次热压焊即同时对电致变色器件的两个电极引线完成焊接，工艺简单，提高了生产效率和产品良率，有利于实现自动化生产，且有利于尽可能减小无法发生变色(即颜色/透过率变化)的电极引出区域的面积。

优选地，所述导通口贯穿所述第一导电基底层；由此，便于将液态形式的导通件的材料从顶部沿着电致变色器件靠近导通口的侧面灌注到导通口内，使所述导通件与第一透明导电层与第二导电区域的电连接更加稳定。
优选地，所述导通件的顶侧的至少部分表面溢出所述导通口，且覆盖至少部分所述第一导电基底层的远离所述电致变色层的一面；由此，能够使所述导通件和第一导电基底层的端面不易开裂，避免第一透明导电层和第二导电区域的电连接失效，黏合效果更好，稳定性更高，提高了生产良率。

所述电致变色层包括依次叠加的电致变色材料层、电解质层和离子储存层；所述电致变色层设置第二隔断区，所述第二隔断区在所述第二透明导电层的投影与所述隔断槽至少部分重合。
本申请中，所述“对合”意指第一导通体的远离第一透明导电层的一面与第二导通体的远离第二导电区域的一面相互贴合。
本申请中，所述第一引出电极和第二引出电极采用导电材料，例如金属、合金、导线、柔性线路板等。
作为本申请的优选技术方案，所述电致变色器件的第二透明导电层被隔断槽分割成相互独立的两个区域，第一引出电极和第二引出电极均从第二透明导电基底层引出，在焊接时可以采用集成两条引出线路的柔性线路板，从而在第二透明导电层一面进行一次热压焊，即可同时实现对第一引出电极和第二引出电极的焊接引出，简化生产工艺，提高了生产效率和产品良率，且有利于减小无法发生变色(即颜色/透过率变化)的电极引出区域的面积。同时，为了避免电致变色器件内部微短路的发生，所述电致变色层上设置第二隔断区，从而避免电致变色层中的导电物质或导电微粒等填充隔断槽，规避了隔断槽的隔断失效的风险。
作为本申请的优选技术方案，所述电致变色器件采用如下方法进行制备，所述方法包括：先分别制备第一层叠件和第二层叠件，其中，所述第一层叠件包括依次层叠的第一基材层、第一透明导电层和电致变色材料层，所述第二层叠件包括依次层叠的第二基材层、第二透明导电层和离子存储层，或，所述第一层叠件包括依次层叠的第一基材层、第一透明导电层和离子存储层，所述第二层叠件包括依次层叠的第二基材层、第二透明导电层和电致变色材料层；再在所述第一层叠件和所述第二层叠件中间设置电解质层，并对合所述第一层叠件和所述第二层叠件。通过预先设置上述的第一导通体和第二导通体，在对合所述第一层叠件和所述第二层叠件时，第一导通体和第二导通体即可对合，可以很方便地将第一透明导电层和第二导电区域紧密连接，从而确保从第二透明导电层的第二导电区域引出的第二电极可以很好地为第一透明导电层供电，工艺简便，大大提高了生产产能。
优选地，所述第一导通体的表面粗糙度大于等于3μm，和/或，所述第二导通体的表面粗糙度大于等于3μm。
作为本申请的优选技术方案，通过对第一导通体和第二导通体的表面粗糙度设置，可以增加第一导通体和第二导通体的对合面的接触点，从而提高第一导通体和第二导通体的接触紧密程度，确保第一导通体和第二导通体的电连通有效性，从而确保第二导电区域引出的第二电极可以很好地为第一透明导电层供电。
优选地，所述第一导通体和第二导通体的侧面的至少部分与所述电致变色层接触；其中，所述电致变色材料层位于靠近所述第二透明导电层的一侧，所述第二隔断区设置于所述电致变色材料层，并将所述电致变色材料层分为相互不连接的两个区域；或，所述离子存储层位于靠近所述第二透明导电层的一侧，所述第二隔断区设置于所述离子存储层，并将所述离子存储层分为相互不连接的两个区域。
本申请的第一导通体和第二导通体的侧面至少部分与电致变色层接触，使得第一导通体、第二导通体和电致变色层之间没有电致变色层的材料空缺，减少了不变色区域的面积。需要说明的是，缺少电致变色层的材料的区域即会形成不变色区域；而且，电致变色材料层和离子存储层的材料在一定情况下具有微小的电子导电率。因此，如果电致变色材料层、离子存储层的材料填充入隔断槽，会导致第一导电区域和第二导电区域的导电材料还是能通过隔断槽内填充的电致变色材料层或离子存储层的材料发生导通，从而导致内部微短路的发生。此外，所述隔断槽也可能由工艺加工过程中的导电颗粒填充，从而导致内部微短路的发生。因此，本申请通过在离子存储层或电致变色材料层上开设第二隔断区，进一步提高了电致变色器件的产品稳定性和使用寿命。
在一种可能的实施方式中，从电致变色材料层或离子存储层的远离第二透明导电层的一面开设第二隔断区。
在另一种可能的实施方式中，从第二基材层的远离电致变色材料层或离子存储层的一面开设第二隔断区。
优选地，所述第二隔断区内填充与所述电解质层的材料相同的电解质材料，以使得所述电解质层通过所述第二隔断区内的电解质材料与所述隔断槽接触。
本申请研究发现，电解质层的材料为电子绝缘体。因此，本申请通过在第二隔断区内填充电解质材料，从而更好地避免内部微短路的发生，进一步提高所述电致变色器件的产品稳定性和使用寿命。
优选地，所述第二透明导电层上设置第二汇流条。
本申请中，所述第二汇流条用于提高第二透明导电层的电压分布均匀性，从而提高电致变色器件的变色速度和变色均匀性。
优选地，所述第一透明导电层上设置第一汇流条，所述第一导通体为所述第一汇流条的局部部分，或，所述第一导通体与所述第一汇流条连接；
所述第二汇流条在所述第一透明导电层上的投影与所述第一汇流条在所述第一透明导电层上的投影互不重合。
本申请中，所述第一汇流条用于提高第一透明导电层的电压分布均匀性，从而提高电致变色器件的变色速度和变色均匀性。通过将所述第一导通体作为第一汇流条的一部分，或将第一汇流条延伸至第一导通体处，从而无需再单独设置第一导通体，在制作第一汇流条时即可将第一导通体制作好，简化了加工步骤，提高了生产产能。通过调节第一汇流条和第二汇流条在平面上的分布情况，使得在由第二透明导电层指向第一透明导电层的方向上，第一汇流条和第二汇流条不会发生上下接触，因为一旦第一汇流条和第二汇流条发生接触，就会导致电致变色器件的短路失效。本申请通过该设计，进一步提高了电致变色器件的产品可靠性。
优选地，所述第二透明导电层的面阻大于所述第一透明导电层的面阻，所述第二汇流条沿所述第一导电区域的周边设置。
本申请中，当第一透明导电层和第二透明导电层的导电材料相同时，面阻越大，导电材料的厚度越小，导电层的光透过率越高，可以提高对电致变色层的颜色的展示效果，但也会导致导电层上的电压分布不均匀，降低电致变色层的变色速率和变色均匀性。因此，本申请通过具有较高面阻的第二透明导电层和具有较低面阻的第一透明导电层的匹配，协同实现电 致变色器件的鲜明地展示电致变色层颜色，以及快速、均匀变色的效果。由于第二透明导电层的面阻较大，因此需要在第二透明导电层上设置第二汇流条，从而提高第二透明导电层的电压分布均匀性，第二汇流条沿第一导电区域的周边设置，从而可以在保证电致变色器件拥有尽可能大的变色区域的同时，提高电致变色器件的变色速度和变色均匀性。在第一导电区域与第二导电区域相邻的周边，可以不设置第二汇流条，以减少短路可能性。由于第一透明导电层的面阻较小，因此，在第一透明导电层上可以不设置第一汇流条，仅设置第一导通体，从而节约产品成本。本申请通过该设计，从而大大提高了对电致变色层颜色的展示效果，以及电致变色器件的产品可靠性、变色速度和变色均匀性。
可选地，所述第二汇流条和电致变色层不相接触，从而避免第二汇流条的金属参与电致变色器件的氧化还原反应。当第二汇流条的材料表面被钝化或覆盖绝缘层等时，第二汇流条和电致变色层也可以接触。
优选地，所述第二透明导电层的面阻与所述第一透明导电层的面阻的比值大于等于1.5，例如可以是1.5、2、2.5、3、3.5、4、4.5、5、6、7、8、9、10、15或20，以及上述点值之间的具体点值，限于篇幅及出于简明的考虑，本申请不再穷尽列举所述范围包括的具体点值。
本申请中，在上述的面阻比值范围下，在所述第二透明导电层设置第二汇流条，第一透明导电层不设置汇流条，可以更优地协同实现电致变色器件的鲜明地展示电致变色层颜色，以及快速、均匀变色的效果。
优选地，所述第二透明导电层的面阻大于所述第一透明导电层的面阻，所述电致变色材料层位于靠近所述第二透明导电层的一侧。
作为本申请的优选技术方案，所述电致变色材料层设置在靠近第二透明导电层的一侧，用户从第一透明导电层的外侧观看时，电致变色器件的颜色展示效果更优。
优选地，所述第一基材层的远离第一透明导电层的一侧设置第一基底，所述第二基材层的远离第二透明导电层的一侧设置第二基底；所述隔断槽贯穿所述第二基材层；所述第一导通体的侧面与所述第二导通体的侧面接触连接；
所述隔断槽与第一透明导电层之间的区域为第一导通区，所述第一导通区内包括第一导通体和第一密封胶；其中，所述第一导通体的至少部分表面上覆盖第一密封胶，以使得所述第一导通体不与所述电致变色层以及所述第二透明导电层接触；
所述第二导电区域与第一基底之间的区域为第二导通区，所述第二导通区内包括第二导通体和第二密封胶；其中，所述第二导通体的至少部分表面上覆盖第二密封胶。
本申请中，所述第一导通体的“侧面”意指第一导通体中与第一透明导电层垂直的面；所述第二导通体的“侧面”意指第二导通体中与第二导电区域垂直的面。
作为本申请的优选技术方案，所述电致变色器件能够通过一次热压焊实现焊接引出，简化生产工艺，提高了生产效率和产品良率；同时，所述第一导通体的侧面与所述第二导通体的侧面接触导通，大大提高了二者的接触面积，从而避免接触不良，提高导通效果；同时，第一导通体和第二导通体的周侧用密封胶填充，一方面可以确保第一导通体和第二导通体的紧密接触，另一方面可以起到密封效果，避免水汽侵入电致变色区，此外还将第一导通体、第二导通体与第一导电区域隔离，起到绝缘效果，避免发生短路。
示例性地，所述电致变色器件通过如下方法进行制备，所述方法包括：
(1)制备电致变色叠层，所述电致变色叠层包括依次层叠的第一基材层、第一透明导电层、电致变色层、第二透明导电层和第二基材层；
(2)分别制备第一导通区和第二导通区；
其中，所述第一导通区的制备方法包括：从第二基材层一侧切割形成隔断槽，所述隔断槽内的第二基材层、第二透明导电层和电致变色层被全部去除；在所述隔断槽内灌注导通材料形成第一导通体，再在所述第一导通体表面填充第一密封胶；在所述第二基材层外侧设置第二基底，形成所述第一导通区；

具体实施方式
下面通过具体实施方式来进一步说明本申请的技术方案。本领域技术人员应该明了，所述实施例仅仅是帮助理解本申请，不应视为对本申请的具体限制。
在一个具体实施方式中，如图1至图6所示，所述电致变色器件包括依次叠加设置的第一导电基底层1、电致变色层2和第二导电基底层3，第一导电基底层1包括依次叠加设置的第一透明导电层11和第一基材层12，第一透明导电层11粘接在电致变色层2的一侧，第二导电基底层3包括依次叠加设置的第二透明导电层31和第二基材层32，第二透明导电层31粘接在电致变色层2的另一侧；第二透明导电层31上开设隔断槽4以使得第二透明导电层31分为两个相互独立的第一导电区域311和第二导电区域312，至少部分第二导电区域312对应的电致变色层2被去除以形成导通口5，导通口5内灌注具有导电性的导通件6，导通件6用于将第一透明导电层11和第二导电区域312电连接。
需要说明的是，首先对第二透明导电层31进行蚀刻，从而开设出隔断槽4以使得第二透明导电层31分为两个相互独立的第一导电区域311和第二导电区域312，第二导电区域312对应的至少部分电致变色层2被去除以形成导通口5，导通口5灌注有液态形式的导通材料，进而转变为固态形式的导通件6，导通件6分别与第一透明导电层11和位于导通口5的第二导电区域312相连通，将第一透明导电层11和第二导电区域312电连接，从而实现同侧电极引出，因此，用于连接第一透明导电层11的电极引线和用于连接第二透明导电层31的电极引线可以均从第二导电基底层3引出，便于通过一次热压焊即同时对电致变色器件的两个电极引线完成焊接，工艺简单，有利于实现自动化生产，大大提高了工作效率和产品良率。
可选地，如图1至图6所示，第一导电区域311至少靠近隔断槽4一侧的表面被电致变色层2覆盖。
需要解释说明的是，由于第一导电区域311靠近隔断槽4一侧的表面被电致变色层2覆 盖，因此，可以确保导通口5灌注导通件6之后，导通件6不会接触到第一导电区域311，从而不会导致第一导电区域311和第二导电区域312发生电连接，进而避免电致变色器件发生短路的情况。
可选地，如图2、图3、图4、图5和图6所示，导通件6的周侧的至少部分表面紧邻电致变色层2。
需要说明的是，由于导通件6的周侧的至少部分表面紧邻电致变色层2，起到支撑和固定导通件6的作用，从而确保第一透明导电层11通过导通件6与第二导电区域312电连接的可靠性。如图2和图3所示的一些实施例中，导通件6的周侧的部分表面紧邻电致变色层2，导通口5均为敞开设置；如图4和图5所示的一些实施例中，导通件6的周侧的全部表面紧邻电致变色层2，导通口5呈容纳槽或者容纳腔的形式。导通件6的周侧的全部表面紧邻电致变色层2相比部分表面紧邻电致变色层2而言，其支撑效果更好、更加稳定。
可选地，如图1至图4以及图6所示，导通口5贯穿第一导电基底层1。可以理解的是，将导通口5贯穿第一导电基底层1设置，便于将液态形式的导通件6从顶部沿着电致变色器件靠近导通口5的侧面灌注到导通口5内，使得导通件6与第一透明导电层11与第二导电区域312的电连接更加稳定。
可选地，如图3所示，导通件6的顶侧的至少部分表面溢出导通口5，且覆盖至少部分第一导电基底层1远离电致变色层2的一面。
需要解释说明的是，如图3所示的实施例中，由于导通件6的顶侧的至少部分表面溢出导通口5，且覆盖至少部分第一导电基底层1远离电致变色层2的一面，则导通件6和第一基材层12的端面不易裂开，避免了第一透明导电层11和第二导电区域312的电连接失效，黏合效果更好，提高了生产良率。
可选地，如图2和图3所示，导通件6的周侧的至少部分表面不贴近电致变色层2。
可以理解的是，如图2和图3所示的实施例，均为导通件6的周侧的至少部分表面不贴近电致变色层2。在形成导通口5时，例如可以通过激光切割后去除导通口5区域对应的第一导电基底层1，然后通过擦拭去除导通口5内的电致变色层2的材料，如图2、3所示的导通口5的右侧无材料等遮挡，这样在去除第一导电基底层1和电致变色层2时，在工艺上都更易于实现，大大提高产品良率。对于如图2和图3的结构，导通件6覆盖在导通口5左侧的侧壁上，依附于第一导电基底层1、电致变色层2的侧面，实现第一透明导电层11和第二导电区域312的电连接。作为优选方案，为了避免导通件6从第一导电基底层1和电致变色层2的侧面裂开，将导通件6的顶部部分覆盖于第一导电基底层1的表面，从而加强导通件6与第一导电基底层1和电致变色层2的侧面的连接稳定性，确保第一透明导电层11和第二导电区域312的电连接的可靠性，避免产品由于断路造成的失效，大大提高了产品的良率。
可选地，如图5所示，导通件6的顶侧覆盖于第一导电基底层1下。如图5所示的实施例中，首先将与导通口5顶侧对应部分的第一导电基底层1的至少相邻的两侧进行蚀刻，将蚀刻部分的第一导电基底层1掀开或取出，用针头将导通件6点浆在导通口5内，再将第一导电基底层1固定在原来的位置，该方式的导通件6与第一汇流条10A的接触面积更大，大大提高了导通良率。
可选地，如图1至图5所示，电致变色器件的导通结构还包括第一汇流条10A，第一汇 流条10A设置于第一透明导电层11表面和/或内部，且第一汇流条10A与导通件6连接。
可以理解的是，由于第一汇流条10A设置于第一透明导电层11表面和/或内部，且第一汇流条10A与导通件6连接，设置第一汇流条10A有助于将电子从导通件6快速传递到整片第一透明导电层11中，提高导电速率，提高变色速度。
补充说明的是，也可在第一导电区域311和第二导电区域312上设置第二汇流条10B，在第一导电区域311和第二导电区域312能够导电的基础上，进一步地提高了导电性能，从而再进一步地提高了导通良率。
可选地，电致变色层2包括叠加的电致变色材料层、电解质层和离子储存层。电致变色材料层、电解质层和离子储存层的材料可以采用现有技术中的材料，本申请对此不作特殊限定。
可选地，第一基材层12远离电致变色层2的一面设置第一基底111(第一水氧阻隔层)；第二基材层32远离电致变色层2的一面设置第二基底112(第二水氧阻隔层)。可以理解的是，第一基材层12和第二基材层32的一面采用水氧阻隔层能够较好地隔绝外部的水汽和氧气，从而避免水汽和氧气进入电致变色层2内影响其正常工作的现象。
有利地，如图6所示，电致变色器件还包括光学胶层(第一光学胶层121和第二光学胶层122)，光学胶层粘接在第一基材层12和/或第二基材层32远离电致变色层2的一面上。可以理解的是，光学胶层能够有效地将水氧阻隔层与第一基材层12和/或第二基材层32相连接，连接牢固、稳定，粘接强度好。
下面结合图2至图6对进行详细说明。

所述电致变色器件在制备过程中，可以预先将第一基底111和第一光学胶层121距离第一基材层12的侧边一定距离贴合，以提供一定面积的第一基材层12表面供导通件6附着；也可以先贴合与第一基材层12同宽的第一光学胶层121和第一基底111，再沿第一基材层12的侧边切除掉一小段第一基底111和第一光学胶层121，以形成如图6上裸露的第一基材层12表面，供导通件6附着。
实施例6
一种电致变色器件，其俯视结构示意图如图7所示，电致变色器件100包括电极引出区域101。

本实施例的电致变色器件在具备实施例8的有益效果的基础上，进一步通过设置第一汇流条和第二汇流条以提高第一透明导电层和第二透明导电层的电压分布均匀性，从而提高电致变色器件的变色速度和变色均匀性。通过将第一导通体作为第一汇流条的一部分，从而无需再单独设置第一导通体，在制作第一汇流条时即可将第一导通体制作好，简化了加工步骤，提高了生产产能。此外再进一步通过调节第一汇流条和第二汇流条在平面上的分布，使得二者不会发生上下接触而导致电致变色器件的短路失效。本实施例大大提高了电致变色器件的变色速度、变色均匀性和产品可靠性。
实施例10
