由此，本申请实施例的延伸部可以对凸出于壳本体的第一部分的边缘进行防护，以降低第一部分被损坏的风险。
在一些实施例中，第一壳体部和第二壳体部的连接处的至少部分凹陷形成卡合部。
由此，本申请实施例的卡合部便于与外部的构件例如卡接部形成卡接，有利于装配。
第三方面，本申请实施例提供了一种检测系统，包括本申请第一方面任一实施例的检测组件或本申请第二面任一实施例的检测装置；以及置物组件，用于容纳待检测物。

由此，本申请实施例的封装部将容纳腔密封为密封结构，以使容纳于容纳腔内的待检测物不容易泄露，且不容易与外部环境中的氧气和/或水汽等发生副反应，有利于保证待检测物检测的准确性。
在一些实施例中，封装部为铝塑层、聚乙烯层或聚丙烯层。
由此，本申请实施例的封装部的密封效果较好，且便于检测组件破坏封装部，以使检测组件的第一部分伸入容纳腔内，并与待检测物接触。
在一些实施例中，盖合部包括盖合本体和朝向第二通孔的几何中心凸出的卡接部，检测装置包括壳体组件，壳体组件包括卡合部，卡合部用于连接卡接部且与卡接部相对设置。
由此，本申请实施例的卡合部与卡接部相配合，其外形相匹配。在检测组件通过第二通孔伸入容纳腔内时，卡合部和卡接部连接，检测组件和置物组件之间不容易松动，结构相对稳定，有利于保证检测的顺利进行。

本申请中出现的“多个”指的是两个以上(包括两个)。
在化工生产领域，为了保证产品的性能，通常需要对产品中的其中一些组分进行含量检测，以调控产品的性能符合生产需求。接下来以生产电池单体为例进行说明。
电池单体包括正极极片和负极极片，正极极片包括正极集流体和设置于正极集流体至少一个表面上的正极活性物质层。负极极片包括负极集流体和设置于负极集流体上至少一个表面上的负极活性物质层。正极活性物质层包括正极活性物质和功能助剂例如多元醇类物质，多元醇类物质能够增加正极活性物质层的塑性，提高正极活性物质层和正极集流体之间的结合力等。
多元醇类物质的含量过低，不能起到良好的塑性作用；而多元醇类物质的含量过高会导致正极活性物质的占比下降，从而降低二次电池的电化学性能；并且会增加正极活性物质层的吸水性能，由此可能会导致正极活性物质层从正极集流体上剥离，甚至出现析锂等问题。故，通常需要对多元醇类物质的含量进行检测，以确保电池单体的性能。
发明人发现，相关技术中主要采用气相色谱法对多元醇类物质的检测，该方法通常需要对制备样品并对样品进行分析，检测时间较长且检测过程较为复杂，严重影响了电池单体的连续化生产。
不仅是对多元醇类物质的检测存在上述问题，在化工生产领域中对一些产品的检测过程也存在检测时间较长且检测过程复杂的问题。
鉴于发明人发现的上述问题，发明人设计了一种检测组件，用于检测待检测物中的预设组分的含量。通过检测组件的显色反应，可以比对得出预设组分的含量。该检测组件不仅适用于电池领域的产品检测，也适用于化工生产的其他领域例如水质检测等。
接下来结合图1至图14对本申请实施例进行详细说明。
[检测组件]
第一方面，本申请实施例提供的一种检测组件。
如图1所示，该检测组件100包括基层1和反应层2。基层1包括彼此连接的第一部分11和第二部分12。第一部分11被配置为与待检测物接触，以使待检测物由第一部分11向第二部分12的方向扩散。反应层2设置于第一部分11的表面，由第一部分11指向第二部分12的方向上，反应层2包括间隔设置的多个子层20，多个子层20被配置为与待检测物依次发生反应并生成反应物，并使得反应物扩散至第二部分12，以使第二部分12的颜色发生变化。在本文中，图1中的X方向即表示由第一部分11指向第二部分12的方向。
待检测物为多种组分构成的混合体系，本申请实施例的检测组件100可以用于检测混合体系中的预设组分的含量，预设组分可以为混合体系中的其中一种或几种组分，例如，预设组分可以为混合体系中影响混合体系性能程度较大的组分。本申请实施例的预设组分的含量可以是指预设组分的质量，也可以指预设组分占据待检测物的质量比。
待检测物可以为多种形态。示例性地，待检测物可以为液态或固态。在待检测 物为液态时，可以直接将定量的待检测物滴加于检测组件100的第一部分11中进行检测；或者利用检测组件100的吸附特性以吸取定量的待检测物进行检测。在待检测物为固态时，可以将待检测物溶解为液态后，然后将液态的待检测物设置于检测组件100中的第一部分11进行检测。示例性地，待检测物为正极浆料或正极极片。以待检测物为正极极片为例进行说明，将正极极片置于溶剂中以溶解正极活性物质层，正极活性物质层被配置为待检测溶液，进而将待检测溶液置于检测组件100中进行检测。
基层1为具有吸液和扩散作用的构件，例如，包含纤维的构件，有利于液体的快速扩散，且基本不会与待检测物发生化学反应，以降低其干扰待检测物检测的准确性。
基层1包括彼此连接的第一部分11和第二部分12。第一部分11和第二部分12的成型方式包括多种，示例性地，第一部分11和第二部分12可以为一体式结构，即第一部分11和第二部分12一体成型，第一部分11和第二部分12之间并无明显的界限。或者，第一部分11和第二部分12独立设置，将独立设置的第一部分11和第二部分12连接后形成基层1。
基层1包括沿其自身厚度方向彼此相对的两个表面。反应层2可以设置于基层1的至少一个表面。示例性地，反应层2设置于基层1的一个表面；或者反应层2设置于基层1的两个表面。反应层2可以通过涂布工艺、压印工艺等形成于基层1的表面。
反应层2包含能够与待检测物中的预设组分发生化学反应的物质。本申请实施例为了提高待检测物中的预设组分检测的准确率，将反应层2设置为包括间隔设置的多个子层20。各子层20可以包含不同的化学物质。待检测物可以依次与子层20发生化学反应，在检测组件100中发生多个化学反应，待检测物逐步发生化学反应，并最终与多个子层20中的靠近第二部分12的子层20发生显色反应，从而保证预设组分含量检测的准确率。
多个子层20中的靠近第二部分12的子层20能够与待检测物发生显色反应产生反应物，反应物能够改变基层1的颜色，反应物扩散至第二部分12后可以改变第二部分12的颜色，可以将第二部分12的颜色和预设颜色集合进行比对，以确定待检测物中的预设组分的含量。在本文中，显色反应是指第二子层22发生化学反应后产生了颜色变化，例如未反应前的第二子层22为无色，反应物为红色，红色的反应物扩散至第二部分12，使得第二部分12变为红色。或者未反应前的第二子层22为黄色，反应物为红色，红色的反应物扩散至第二部分12，使得第二部分12变为红色。预设颜色集合可以为预先设置的色卡，预设颜色集合包含颜色和预设组分的含量的对应关系。因此，通过将第二部分12的颜色和预设颜色集合进行比对，可以确定预设组分的含量。
作为一些示例，如图1和图2所示，多个子层20可以包括两个子层20，例如多个子层20包括第一子层21和第二子层22，第二子层22靠近第二部分12设置，第一子层21位于第二子层22的背离第二部分12的一侧。检测组件100吸取待检测物，待检测物由第一部分11向第二部分12的方向扩散，并先扩散至与第一子层21对应的第一部分11的区域位置，然后待检测物能够与第一子层21发生化学反应从而生成初产物。该初产物继续扩散至与第二子层22对应的第一部分11的区域位置，然后该初产物 能够与第二子层22发生化学反应从而生成反应物，该反应物具有不同于初始第二部分12的颜色。该反应物继续扩散至第二部分12，第二部分12显示反应物的颜色，由第二部分12显示的颜色，确定预设组分的含量。图2中示出了多个子层20包括第一子层21和第二子层22的示例。
作为另一些示例，多个子层20可以包括三个子层20。例如多个子层20由第一部分11指向第二部分12的方向上，多个子层20包括间隔设置的第一子层21、第三子层和第二子层22，第二子层22靠近第二部分12设置，第一子层21位于第二子层22的背离第二部分12的一侧，第三子层位于第一子层21和第二子层22之间。检测组件100吸取待检测物，待检测物由第一部分11向第二部分12的方向扩散，并先扩散至与第一子层21对应的第一部分11的区域位置，然后待检测物能够与第一子层21发生化学反应从而生成初产物。该初产物继续扩散至与第三子层对应的第一部分11的区域位置，然后该初产物能够与第三子层发生化学反应从而生成次产物。该次产物继续扩散至与第二子层22对应的第一部分11的区域位置，然后该次产物能够与第二子层22发生化学反应从而生成反应物，该反应物具有不同于初始第二部分12的颜色。该反应物继续扩散至第二部分12，第二部分12发生颜色变化，由第二部分12显示的颜色，确定预设组分的含量。
作为再一些示例，多个子层20还可以包括四个子层20、五个子层20等等，在此并不对子层20的数量进行限定，子层20的数量可以根据生产需求灵活选用。
根据本申请实施例的检测组件100，待检测物能够由第一部分11向第二部分12扩散，在第一部分11向第二部分12扩散的过程中，待检测物预先与多个子层20中的背离第二部分12的子层20发生化学反应，发生化学反应后的待检测物向第二部分12的方向扩散，并扩散至多个子层20中的靠近第二部分12的子层20并发生化学反应生成反应物，该反应物具有不同于第二部分12的颜色，从而能够使得第二部分12的颜色发生变化，从而能够由第二部分12的颜色确定待检测物中的预设组分的含量。本申请实施例通过待检测物与子层20发生化学反应，以检测待检测物中预设组分的含量，检测过程简单；并且由于在待检测物扩散过程中即可完成化学反应，由此可以缩短检测时间。
在一些实施例中，基层1可以包括棉纤维层和/或玻璃纤维层。该类纤维层具有较好的扩散能力，有利于待检测物的扩散；且有利于反应物形成于基层1上。
在本申请实施例中，基层1可以设置为单层或多层结构形式。示例性地，基层1可以包括棉纤维层；或者基层1可以包括玻璃纤维层；再或者基层1包括棉纤维层和玻璃纤维层，棉纤维层和玻璃纤维层可以沿基层1的厚度方向层叠设置。
本申请实施例的基层1包括多种结构形式，通过对基层1结构形式的选取，可以调节待检测物的检测时长等。
在一些实施例中，如图2和图3所示，第一部分11的至少部分表面为平坦表面。示例性地，第一部分11的部分表面为平坦表面，或者第一部分11的全部表面为平坦表面。反应层2的多个子层20设置于平坦表面上，检测组件100的整体占用空间较小。待检测物在平坦表面上的扩散路径较短，有利于待检测物的快速扩散，适用于活 性较高、反应迅速的待检测物。
在另一些实施例中，如图4和图5所示，第一部分11的至少部分表面可以为凹凸不平的表面。第一部分11的至少部分表面具有多个凹陷部11a和相对于凹陷部11a凸出的多个凸出部11b，相邻的两个凹陷部11a之间设置有凸出部11b，其中，反应层的多个子层20设置于多个凹陷部11a和多个凸出部11b上。
示例性地，第一部分11的全部表面为凹凸不平的表面。或者，第一部分11的一部分表面为平坦表面，另一部分表面为凹凸不平的表面。
反应层设置于凹凸不平的表面时，待检测物的扩散路径较长，有利于延长待检测物的反应时间，从而能够使得待检测物和反应层的反应时间增加，以确保待检测物和反应之间充分发生化学反应，进而提高对待检测物中的预设组分的含量检测的准确性。此外，反应层设置于凹凸不平的表面时，反应层的多个子层20和第一部分11的表面的结合力更强，反应层不容易从第一部分11上剥离。
在一些实施例中，如图6所示，第一部分11包括第一连接部111和第二连接部112。第一连接部111的表面设置有反应层2。第二连接部112连接于第一连接部111的背离第二部分12的一侧，第二连接部112被配置为与待检测物检测，以使待检测物由第二连接部112向第一连接部111扩散。
第二连接部112上并未设置反应层2，其主要用于扩散将待检测物扩散至第一连接部111，以使与第一连接部111相对应的反应层2进行反应。本申请实施例设置第二连接部112，可以将第二连接部112直接置于容纳有待检测物的设备中，有利于检测操作，有利于扩展检测组件100的适用范围。
进一步地，第二连接部112的表面可以设置为平坦表面，第一连接部111的表面可以设置为凹凸不平的表面。鉴于第二连接部112的表面为平坦表面，其扩散路径较短，待检测物可以经第二连接部112快速扩散至第一连接部111，且能够降低待检测物在第二连接部112上的损失量。第一连接部111的表面设置为凹凸不平的表面，待检测物的扩散路径较长，待检测物能够与反应层2中的各子层20充分反应，从而能够提高待检测物中的预设组分检测的准确性。
当然，第二连接部112和第一连接部111的表面均设置为平坦表面；或者，第二连接部112的表面可以设置为凹凸不平的表面，第一连接部111的表面可以设置为平坦表面。
本申请实施例的第一连接部111和第二连接部112可以为一体式结构，第一连接部111和第二连接部112一体成型，二者之间并没有明显的界限，能够降低待检测物在二者连接处的损失，从而提高检测准确性。当然，第一连接部111和第二连接部112可以为独立设置，然后将第一连接部111和第二连接部112连接。
在本申请实施例中，反应层2包括多个间隔设置的子层20，换言之，多个子层20之间具有间距。图6中示出的d表示相邻两个子层20之间的间距。
在一些实施例中，相邻两个子层20之间的间距为5mm～10mm。
相邻两个子层20之间的间距满足上述范围时，可以降低相邻子层20之间分别发生化学反应时发生干扰的风险，也降低相邻子层20间的化合物互相掺杂的可能性， 能够给予每个子层20充分反应的空间，从而提高检测准确性。相邻两个子层20之间的间距为5mm～10mm，进一步地，相邻两个子层20之间的间距可以为5mm～8mm。示例性地，相邻两个子层20之间的间距可以为5mm、5.5mm、6mm、6.5mm、7mm、7.5mm、8mm、8.5mm、9mm、9.5mm或10mm，也可以为上述任两个数值组成的组合。
在一些实施例中，请继续参阅图6，由第一部分11指向第二部分12的方向上，多个子层20包括间隔设置的第一子层21和第二子层22。第二子层22靠近第二部分12设置，第一子层21位于第二子层22的背离第二部分12的一侧。接下来以待检测物包含多元醇类化合物为例进行说明。
第一子层21包括对甲基苯磺酸钠、柠檬酸物质或固体草酸。对甲基苯磺酸钠等能够与多元醇类物质发生化学反应，以使多元醇类物质呈酸性。换言之，第一子层21能够赋予待检测物以酸性，为后续的反应作准备。
第二子层22包括重铬酸钾或高锰酸钾。重铬酸钾等物质能够与酸性的多元醇类物质发生氧化还原反应，并使得重铬酸钾的颜色发生变化。换言之，第二子层22在第一层和待检测物发生反应的基础上，继续进行反应生成反应物，该反应物和第二子层22的初始颜色不同，从而改变了第二子层22的颜色，并继续扩散至第二部分12，并改变第二部分12的颜色。
在一些实施例中，可以通过对第一子层21的参数进行调控，以确保第一子层21和待检测物充分发生化学反应。在本文中，第一子层21的参数可以是第一子层21的质量、厚度、和面积中的至少一者。第一子层21的参数还可以是第一子层21的宽度或长度等。
作为一些示例，第一子层21的质量为0.11mg/n～0.2mg/n，可选为0.2mg/n，其中，n表示多元醇类化合物中的羟基数量。
作为另一些示例，第一子层21的厚度为80μm～100μm，可选为100μm。
作为再一些示例，第一子层21的面积为90mm 2～120mm 2，可选为110mm 2。
在一些实施例中，可以通过对第二子层22的参数进行调控，以确保第二子层22和待检测物充分发生化学反应。在本文中，第二子层22的参数可以是第二子层22的质量、厚度、和面积中的至少一者。第二子层22的参数还可以是第二子层22的宽度或长度等。
第二子层22的质量为0.3mg/n～0.4mg/n，可选为0.35mg/n，其中，n表示多元醇类化合物中的羟基数量。
第二子层22的厚度为80μm～100μm，可选为90μm。
第二子层22的面积为90mm 2～120mm 2，可选为120mm 2。

壳体组件200设置于检测组件100外，可以给予检测组件100以防护作用，且 有利于检测操作。壳体组件200的形状可以根据检测组件100的结构灵活选用，例如检测组件100为长形层状结构体，壳体组件200可以为具有安装空间的长方体结构；或者检测组件100为圆柱状结构，壳体组件200可以为具有安装空间的圆柱状结构。
根据本申请实施例的检测装置1000，待检测物能够由第一部分11向第二部分12扩散，在第一部分11向第二部分12扩散的过程中，待检测物分别与检测组件100的各子层发生化学反应并生成反应物，该反应物具有不同于第二部分12的颜色，从而能够使得第二部分12的颜色发生变化，从而能够由第二部分12的颜色确定待检测物中的预设组分的含量，检测过程简单；并且由于在待检测物扩散过程中即可完成化学反应，由此可以缩短检测时间。
在一些实施例中，请继续参阅图7至图9，检测组件100包括第一部分11，第一部分11的至少部分凸出于壳体组件200，有利于第一部分11与待检测物接触，从而使得待检测物可以由第一部分11向第二部分12扩散。
在另一些实施例中，第一部分11位于壳体组件200内，换言之，第一部分11可以不凸出于壳体组件200，相应地，壳体组件200具有开口240，该开口240与第一部分11的背离第二部分12的端部相对设置。该开口240的设置可以使得待检测物能够从该开口240与第一部分11接触，以使待检测物进一步由第一部分11向第二部分12扩散。
在一些实施例中，请继续参阅图7至图9，为了便于观察检测组件100的第二部分12的颜色变化，壳体组件200可以包括第一通孔211，第一通孔211与第二部分12的至少部分相对设置，以便于在操作时通过第一通孔211观察第二部分12的颜色变化，对第二部分12进行比色，以确定待检测物中的预设组分的含量。
在另一些实施例中，第二部分12的至少部分可以凸出于壳体组件200，可以直接通过位于壳体组件200外的第二部分12的颜色变化，对第二部分12进行比色，以确定待检测物中的预设组分的含量。
在一些实施例中，请继续参阅图7至图9，壳体组件200包括第一壳体部210和第二壳体部220。第二壳体部220与第一壳体部210连接且相对设置，第二壳体部220和第一壳体部210之间形成具有开口240的安装空间，安装空间用于设置检测组件100。第一部分11的至少部分穿过开口240凸出于第一壳体部210和第二壳体部220中的至少一者；和/或第一壳体部210和第二壳体部220的至少一者上设置有第一通孔211。
第一壳体部210和第二壳体部220之间可以是固定连接，壳体组件200的整体稳定性较高；例如，第一壳体部210和第二壳体部220为一体结构。第一壳体部210和第二壳体部220之间可以是可拆卸连接，便于更换检测组件100。第一壳体部210和第二壳体部220共同对检测组件100进行防护，以提高对检测组件100的防护能力。
第一部分11的至少部分穿过开口240凸出于第一壳体部210，第一部分11的至少部分显露于外部环境，便于与待检测物接触。或者，第一部分11的至少部分穿过开口240凸出于第二壳体部220，第一部分11的至少部分显露于外部环境，便于与待检测物接触。当然，第一部分11的至少部分可以穿过开口240同时凸出于第一壳体部210和第二壳体部220。
第一通孔211可以设置于第一壳体部210，即第一通孔211沿第一壳体部210的厚度方向贯穿第一壳体部210，可以通过第一通孔211观察第二部分12的颜色。或者，第一通孔211可以设置于第二壳体部220，即第一通孔211沿第二壳体部220的厚度方向贯穿第二壳体部220，可以通过第一通孔211观察第二部分12的颜色。当然，第一壳体部210和第二壳体部220上均可以设置第一通孔211，更有利于操作者观察第二部分12的颜色。
在一些实施例中，请继续参阅图7至图9，第一壳体部210包括壳本体212和凸出于壳本体212的两个延伸部213，两个延伸部213相对设置，其中，第一部分11的至少部分凸出于壳本体212，并位于两个延伸部213之间。

在一些实施例中，第二壳体部220可以与第一壳体部210为相同的结构，当然也可以结构不同。例如，第二壳体部220可以包括壳本体212。
在一些实施例中，请继续参阅图7至图9，第一壳体部210和第二壳体部220的连接处的至少部分凹陷形成卡合部230。卡合部230便于与外部的构件例如卡接部形成卡接，有利于装配。

根据本申请实施例的检测系统2000，待检测物容纳于置物组件300中，检测组件100或检测装置1000的第一部分能够吸取待检测物，并使得待检测物能够由第一部分向第二部分扩散，在第一部分向第二部分扩散的过程中，待检测物分别与各子层发生化学反应并生成反应物，该反应物具有不同于第二部分的颜色，从而能够使得第二部分的颜色发生变化，从而能够由第二部分的颜色确定待检测物中的预设组分的含量，检测过程简单；并且由于在待检测物扩散过程中即可完成化学反应，由此可以缩短检测时间。
在一些实施例中，请参阅图10至图13，置物组件300可以包括置物本体310和盖合部320。置物本体310包括用于容纳待检测物的容纳腔311。盖合部320盖合于置物本体310，且盖合部320包括与检测组件100相对设置的第二通孔330，其中，置物本体310和盖合部320中的至少一者包括封装部340，以密封容纳腔311，且检测组件100能够通过第二通孔330穿过封装部340并延伸至容纳腔311内。
封装部340可以设置于置物本体310，也可以设置于盖合部320，或者在置物本体310和盖合部320上均设置封装部。
封装部340将容纳腔311密封为密封结构，以使容纳于容纳腔311内的待检测物不容易泄露，且不容易与外部环境中的氧气和/或水汽等发生副反应，有利于保证待检测物检测的准确性。
在一些实施例中，封装部340可以为铝塑层、聚乙烯层或聚丙烯层。上述封装部340的密封效果较好，且便于检测组件100破坏封装部340，以使检测组件100的第一部分11伸入容纳腔311内，并与待检测物接触。
在一些实施例中，盖合部320包括盖合本体321和朝向第二通孔330的几何中心凸出的卡接部322。相应地，检测装置1000包括壳体组件200，壳体组件200包括卡合部230，卡合部230用于连接卡接部322，且与卡接部322相对设置。卡合部230与卡接部322相配合，其外形相匹配。在检测组件100通过第二通孔330伸入容纳腔311内时，卡合部230和卡接部322连接，检测组件100和置物组件300之间不容易松动，结构相对稳定，有利于保证检测的顺利进行。
[检测方法]
第四方面，本申请实施例还提供了一种检测方法，该检测方法用于检测待检测物中的预设组分的含量。如图14所示，该方法包括：
S100，提供待检测物，将待检测物配置为待检测溶液。
S200，提供检测组件，检测组件包括基层和反应层，基层包括彼此连接的第一部分和第二部分，反应层设置于第一部分的表面，由第一部分指向第二部分的方向上，反应层包括间隔设置的多个子层。
S300，将第一部分与待检测溶液接触，以使待检测溶液中的待检测物由第一部分向第二部分的方向扩散，并依次与多个子层发生反应生成反应物，反应物扩散至第二部分以改变第二部分的颜色。
S400，将第二部分的颜色与预设颜色集合进行比对，以确定预设组分的含量。
在待检测物为液态时，待检测物可以直接作为待检测溶液。在待检测物为固态时，可以将待检测物溶解于溶剂中形成待检测溶液。
本申请实施例所采用的方法，检测过程简单；并且由于在待检测物扩散过程中即可完成化学反应，由此可以缩短检测时间。
如图6和图10，作为一具体实施例，检测装置1000包括置物组件300、壳体组件200和检测组件100，检测组件100的至少部分设置于壳体组件200内。
置物组件300用于容纳待检测物。置物组件300可以包括置物本体310和盖合部320。置物本体310包括用于容纳待检测物的容纳腔311。盖合部320盖合于置物本体310，且盖合部320包括与检测组件100相对设置的第二通孔330，其中，盖合部320包括封装部340，以密封容纳腔311，且检测组件100能够通过第二通孔330穿过封装部340并延伸至容纳腔311内。
检测组件100包括基层1和反应层2。基层1包括彼此连接的第一部分11和第二部分12。第一部分11包括第一连接部111和第二连接部112。第一连接部111的表面设置有反应层2。第二连接部112连接于第一连接部111的背离第二部分12的一侧，第二连接部112被配置为与待检测物检测，以使待检测物由第二连接部112向第一连接 部111扩散。反应层2包括第一子层21和第二子层22。第一子层21位于第二子层22的背离第二部分12的一侧。第二连接部112的部分凸出于壳体组件200。
以待检测物为正极极片为例进行检测过程的说明。
提供预设重量的正极极片，将正极极片置于容纳腔311中溶解。容纳腔311内可以预先放置柠檬酸钠溶液，柠檬酸钠溶液可以起到活化多元醇的作用。正极极片中的正极浆料在柠檬酸钠溶液中溶解后摇匀、静置为待检测正极浆料。需要说明的是，正极极片中的正极集流体基本不会溶解，正极极片上涂覆的正极浆料溶解形成待检测正极浆料，对待检测正极浆料中的多元醇类物质进行含量检测。
将检测组件100的第二连接部112插入置物组件310的盖合部320中，并穿过封装部340并延伸至容纳腔311内，与待检测正极浆料接触。待检测正极浆料由第二连接部112向第一连接部111扩散，当扩散至第一子层21所对应的基层1的区域时，待检测正极浆料中的多元醇和第一子层21发生化学反应。第一子层21可以为对甲基苯磺酸钠，对甲基本酸钠赋予待检测正极浆料中的多元醇以酸性。然后，待检测正极浆料继续扩散至第二子层22所对应的基层1的区域，被赋予酸性的多元醇和第二子层22发生化学反应。第二子层22可以采用重铬酸钾。多元醇和重铬酸钾发生氧化还原反应生成反应物，并发生颜色变化，由于颜色变化具有一定的滞后性，故反应物继续向第二部分12扩散，扩散至第二部分12时可以通过第二部分12的颜色和预设颜色集合进行比对，确定多元醇的含量。
示例性地，容纳腔311含有20ppm柠檬酸钠溶液，容纳腔311内柠檬酸钠溶液高度为30ml，插入第二连接部112后，容纳腔311内溶液高度升高，使得与第二连接部112接触的柠檬酸钠溶液体积为标准的7.0ml。通过上述步骤可以使得所测定的多元醇溶液的体积恒定，以此可以定量检测正极浆料中的多元醇的含量，并结合第二部分12的颜色可准确确定含量。
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
最后应说明的是：以上实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换，但这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的精神和范围。
