背景技术
软包电池是指采用铝塑膜包装的聚合物电池，通常为锂聚合物电池，多用于手机、平板电脑等电子设备。
电子设备在安装及拆卸软包电池时，包括以下几种方式：方式(1)，通过具有粘接剂的普通胶带直接将软包电池粘接到电子设备的电池仓内，该方式中，由于软包电池的表面与普通胶带直接粘接，因此在维修需要拆卸软包电池时，将软包电池从电池仓内拉出，容易使软包电池的表面被普通胶带拉扯变形、破损或起皱等。破损的软包电池在使用的过程中容易出现发热鼓胀，使得软包电池维修后使用的过程中出现安全隐患，甚至导致软包电池维修后无法再进行重复使用。方式(2)，为了避免软包电池的表面与普通胶带直接粘接，利用包裹膜将软包电池包裹起来，包裹方式可以为一层或多层缠绕包裹，该包裹膜可为现有成品的透明塑料膜。当软包电池被包裹至少一层的包裹膜之后，再利用胶带将包裹膜漏出的头部接缝进行粘接，或该包裹膜的接头部带有粘接剂，通过该粘接剂将包裹膜头部接缝进行粘接。然后，利用普通胶带直接将包裹有包裹膜的软包电池粘接到电子设备的电池仓内，如图1所示，图1中101为软包电池，102为包裹膜，103为普通胶带，104为电池仓。该方式(2)中在拆卸软包电池时，需要用刀等利器将包裹膜剥开或从包裹膜头部粘接的接缝撕开方可取出软包电池。
由于用包裹膜将软包电池进行包裹，包裹膜与软包电池表面之间的附着力较弱，在对软包电池进行包裹时，包裹膜容易形成宽松空间，从而使得软包电池容易在包裹膜的宽松空间内松动，导致包裹效果较差，可靠性较低。而且，该包裹膜除了用膜体进行缠绕外还需要有粘接剂将接缝进行粘接，加上包裹膜不易剥开，导致软包电池拆卸较困难。
发明内容
为了解决现有技术中包裹膜与软包电池的外层表面之间的附着力较弱，包裹效果较差及可靠性较低，且包裹膜使得软包电池拆卸较困难的问题，本申请实施例提供一种电池包裹膜的形成方法，在软包电池的外层表面涂覆液体，并对涂覆液体的软包电池进行固化处理，使该液体固化后形成包裹膜，该包裹膜为一体化薄膜层，可与软包电池的外层表面形成较好的一体化附着效果，可靠性较高，且通过在包裹膜上粘贴的粘性物将软包电池安装在电池仓内时，由于包裹膜较薄，包裹膜将软包电池与粘性物进行隔离，在拆卸软包电池时，很容易剥离包裹膜而从电池仓取出软包电池。本申请实施例还提供了一种电池组件及电子设备。
本申请实施例第一方面提供了一种电池包裹膜的形成方法，可包括：在软包电池的外 层表面涂覆液体，涂覆液体的方式可以是在软包电池的外层表面喷涂液体，也可以是将软包电池的外层表面浸泡在液体内后取出，还可以其他的涂覆方式。然后，对涂覆液体后的软包电池进行固化处理，得到包裹在软包电池的外层表面的包裹膜，包裹膜为一体化薄膜层。该固化处理包括紫外光照射固化、加热固化或湿气固化等，当然该固化处理还可以包括其他的固化方式。该固化处理用于固化液体以形成一体化薄膜层的包裹膜，包裹膜附着于软包电池的外层表面，而无需粘接剂。软包电池被一体化薄膜层的包裹膜包裹后，将软包电池在与电子设备进行组装时，通过在包裹膜上粘贴的粘性物将软包电池安装在电子设备的电池仓内，这样包裹膜可以将软包电池与粘性物隔离。该电子设备可以是手机、平板电脑等，该粘性物可以是胶带或胶水等，还可以是其他具有粘接剂的物体。当需要拆卸软包电池时，只需将包裹膜剥离后即可从电池仓内取出软包电池。由于该液体固化后形成包裹膜，该包裹膜为一体化薄膜层，可与软包电池的外层表面形成较好的一体化附着效果，可靠性较高，且通过在包裹膜上粘贴的粘性物将软包电池安装在电池仓内时，由于包裹膜较薄，包裹膜将软包电池与粘性物进行隔离，在拆卸软包电池时，可快速剥离软包电池的外层表面的包裹膜，使软包电池与电池仓无损分离，不仅提升了拆卸软包电池的效率，而且使软包电池可实现复用性。
结合本申请实施例第一方面，在本申请实施例第一方面的第一种实施方式中，由于液体在常温下或在密封保存等情况下为液体状态，为了使液体能够在软包电池的外层表面固化凝结成包裹膜，因此需要对液体进行固化处理。对涂覆液体后的软包电池进行固化处理可包括：对涂覆液体后的软包电池进行紫外光照射固化、加热固化或湿气固化等，当然，该固化处理还可以是其他的固化方式，只要能实现对液体的固化即可，提高了对液体进行固化的灵活性。在进行固化处理后使液体在软包电池的外层表面表干，液体可快速固化，凝结成的包裹膜为超薄的一体化薄膜层，并且在固化后具有较好韧性和延展性，不仅对软包电池起保护作用，还可以在拆卸时快速将软包电池与电池仓无损分离。
结合本申请实施例第一方面或本申请实施例第一方面的第一种实施方式，在本申请实施例第一方面的第二种实施方式中，在软包电池的外层表面涂覆液体的区域可以进行灵活设置，可以是软包电池的外层表面完全涂覆，也可以是软包电池的外层表面局部覆盖涂覆。例如，为了对软包电池的外层表面进行全局保护，方便安装，可以在软包电池的全部外层表面涂覆液体。或者是，为了节省液体的成本，可以在软包电池与电池仓接触的其中一面外层表面涂覆液体。或者是，为了方便大批量生产，可以规定在软包电池与正负触点表面相邻的四面外层表面涂覆液体。该液体不仅其材料成本低，而且在软包电池的外层表面涂覆方便，可实现在软包电池的外层表面的自动化涂覆及固化，提高了生产效率。
结合本申请实施例第一方面、本申请实施例第一方面的第一种实施方式或本申请实施例第一方面的第二种实施方式，在本申请实施例第一方面的第三种实施方式中，液体的主要作用就是能够在软包电池的外层表面固化形成一体化薄膜层的包裹膜，为了实现该目的，例如，该液体可以是一种液态保护膜，该液体的材料例如可以为环氧材料、聚氨酯或聚丙烯等可快速固化的单一成分的液体。该液体固化后可与软包电池的外层表面形成较好的附着效果，可以对电池形成较好的防护，使软包电池更容易拆卸，减少拆卸过程中软包电池 的外层表面的破损，实现软包电池可重复使用。
结合本申请实施例第一方面、本申请实施例第一方面的第一种实施方式至第三种实施方式中的任意一种，在本申请实施例第一方面的第四种实施方式中，通过在软包电池的外层表面涂覆液体，并固化液体形成一体化薄膜层的包裹膜，提高了包裹膜的膜厚的可控性，例如，若需要包裹膜的膜厚较薄，则可少量喷涂液体；若需要包裹膜的膜厚较厚，则可大量喷涂液体。为了达到利用薄膜层隔离粘性物与软包电池的外层表面的直接接触，且尽量减少液体的用量的目的，可以涂覆薄膜层的厚度为20微米至40微米的范围内。这样包裹膜较薄，不仅不影响软包电池整体厚度及可靠性，而且使软包电池在电子设备维修时易拆卸。
结合本申请实施例第一方面、本申请实施例第一方面的第一种实施方式至第四种实施方式中的任意一种，在本申请实施例第一方面的第五种实施方式中，由于粘性物的主要作用就是将将软包电池安装于电子设备的电池仓内，因此，该粘性物可以是胶带或胶水，例如，该胶带可以是双面胶带，或者是带有粘接剂的物体。
本申请实施例第二方面提供了一种电池组件，该电池组件包括软包电池，以及采用前述本申请实施例第一方面、以及本申请实施例第一方面的第一种实施方式至本申请实施例第一方面的第五种实施方式中的任一实施例的电池包裹膜的形成方法制作的包裹膜，该包裹膜包裹在软包电池的外层表面。
本申请实施例第三方面提供了一种电子设备，该电子设备可包括：电池仓、粘性物和电池组件，其中，电池组件包括软包电池和包裹膜，软包电池的外层表面包裹该包裹膜，该包裹膜是通过在软包电池的外层表面涂覆液体并对液体进行固化处理得到的。涂覆液体的方式可以是在软包电池的外层表面喷涂液体，也可以是将软包电池的外层表面浸泡在液体内后取出，还可以其他的涂覆方式。该固化处理包括紫外光照射固化、加热固化或湿气固化等，当然该固化处理还可以包括其他的固化方式。该固化处理用于固化液体以形成一体化薄膜层的包裹膜，包裹膜附着于软包电池的外层表面，而无需粘接剂。软包电池通过粘性物安装于电池仓内，在拆卸时通过剥离包裹膜从电池仓中取出软包电池。该电子设备可以是手机、平板电脑等。该粘性物可以是胶带或胶水等，还可以是其他具有粘接剂的物体。由于该液体固化后形成包裹膜，该包裹膜为一体化薄膜层，可与软包电池的外层表面形成较好的一体化附着效果，可靠性较高，且通过在包裹膜上粘贴的粘性物将软包电池安装在电池仓内时，由于包裹膜较薄，包裹膜将软包电池与粘性物进行隔离，在拆卸软包电池时，可快速剥离软包电池的外层表面的包裹膜，使软包电池与电池仓无损分离，不仅提升了拆卸软包电池的效率，而且使软包电池可实现复用性。
结合本申请实施例第三方面，在本申请实施例第三方面的第一种实施方式中，为了方便将软包电池放入电池仓，或方便将软包电池从电池仓取出，电池仓设置有用于放入或取出软包电池的镂空部，该镂空部的设置位置及大小可以根据实际需要进行灵活设置，例如，可以将镂空部的大小设置为比软包电池其中的一个表面的面积稍大，方便用手指、镊子或夹子等取出软包电池。
结合本申请实施例第三方面或本申请实施例第三方面的第一种实施方式，在本申请实施例第三方面的第二种实施方式中，通过在软包电池的外层表面涂覆液体，并固化液体形 成一体化薄膜层的包裹膜，提高了包裹膜的膜厚的可控性，例如，若需要包裹膜的膜厚较薄，则可少量喷涂液体；若需要包裹膜的膜厚较厚，则可大量喷涂液体。为了达到利用薄膜层隔离粘性物与软包电池的外层表面的直接接触，且尽量减少液体的用量的目的，可以涂覆薄膜层的厚度为20微米至40微米的范围内。这样包裹膜较薄，不仅不影响软包电池整体厚度及可靠性，而且使软包电池在电子设备维修时易拆卸。
结合本申请实施例第三方面、本申请实施例第三方面的第一种实施方式或本申请实施例第三方面的第二种实施方式，在本申请实施例第三方面的第三种实施方式中，由于粘性物的主要作用就是将将软包电池安装于电子设备的电池仓内，因此，该粘性物可以是胶带或胶水，例如，该胶带可以是双面胶带，或者是带有粘接剂的物体。
本申请实施例通过在软包电池的外层表面涂覆液体并进行固化处理，使得液体固化形成包裹膜，该包裹膜附着于软包电池的外层表面，对软包电池进行一体化包裹。然后，将附着有包裹膜的软包电池通过粘性物安装于电池仓内，在拆卸软包电池时，将包裹膜剥离形成开口即可取出软包电池。由于该液体固化后形成包裹膜，该包裹膜为一体化薄膜层，可与软包电池的外层表面形成较好的一体化附着效果，可靠性较高，且通过在包裹膜上粘贴的粘性物将软包电池安装在电池仓内时，由于包裹膜较薄，在拆卸软包电池时，很容易剥离包裹膜而从电池仓取出软包电池。

具体实施方式
为了解决现有技术中包裹膜与软包电池的外层表面之间的附着力较弱，包裹效果较差及可靠性较低，且包裹膜使得软包电池拆卸较困难的问题，本申请实施例提供一种电池包裹膜的形成方法，在软包电池的外层表面涂覆液体，并对涂覆液体的软包电池进行固化处理，使该液体固化后形成包裹膜，该包裹膜为一体化薄膜层，该薄膜层可与软包电池的外层表面形成较好的一体化附着效果，可靠性较高，且通过在包裹膜上粘贴的粘性物将软包电池安装在电池仓内时，包裹膜将软包电池与粘性物进行隔离，由于包裹膜较薄，在拆卸软包电池时，很容易剥离包裹膜而从电池仓取出软包电池。本申请实施例还提供相应的电池组件及电子设备，以下分别进行详细说明。
如图2所示，本申请实施例中电池包裹膜的形成方法的一个实施例包括：
201、在软包电池的外层表面涂覆液体；
本实施例中，液体在常温下或在密封保存下等情况时处于液体状态，处于液体状态的 液体在外界环境的作用下，例如高温或紫外光等的作用下，可发生状态的变化，例如，可由液体状态转变为固体状态。
由于液体为液体状态，因此在软包电池的外层表面涂覆液体时，可以在液体为液体状态的环境下，将液体装入液态容器内，通过装有液体的液态容器在软包电池的外层表面喷涂液体。可以理解的是，在实际应用中，在软包电池的外层表面涂覆液体的方式，除了在软包电池的外层表面喷涂液体之外，还可以是其他的涂覆方式，例如，在液体为液体状态的环境下，将软包电池的外层表面浸泡在液体内，使软包电池的外层表面充分沾上液体后，取出软包电池，还可以是滚筒或刷涂等方式，具体此处不作限定。
202、对涂覆液体的软包电池进行固化处理，得到包裹在软包电池的外层表面的包裹膜，包裹膜为一体化薄膜层。
为了使软包电池的外层表面所涂覆的液体固化成包裹膜，需要对涂覆液体后的软包电池进行固化处理，该固化处理用于固化液体以形成一体化薄膜层的包裹膜，该包裹膜附着于软包电池的外层表面，而无需粘接剂。该固化处理可以是通过加热涂覆有液体的软包电池，使软包电池的外层表面的液体受热固化形成一体化薄膜层的包裹膜。需说明的是，为了不影响电池的性能，且保证液体能够固化，加热固化时所采用的温度可设置为30℃至60℃的范围内，可以理解的是，在实际应用中，对于耐热性较好的软包电池来说，也可以将加热的温度可设置为40℃至80℃的范围内，还可以根据液体的不同材料及软包电池能够承受的温度等因素将加热温度设置为其他的温度范围，具体此处不作限定。加热固化的加热时间可以根据实际需要进行灵活设置，具体此处不作限定。
可以理解的是，在实际应用中，该固化处理除了为加热固化之外，还可以是其他的固化方式，例如，紫外光照射固化或湿气固化等，具体此处不作限定。当固化处理为紫外光照射固化时，紫外光照射的强度及时间，可以根据实际需要进行灵活设置；或当固化处理为湿气固化时，湿气固化的湿度及时间，可以根据实际需要进行灵活设置，具体此处不作限定。
对涂覆液体的软包电池进行固化处理后，可得到包裹在软包电池的外层表面的包裹膜，包裹膜为一体化薄膜层。当需要将软包电池与电子设备进行组装时，通过在包裹膜上粘贴的粘性物将软包电池安装在电子设备的电池仓内，使得包裹膜将软包电池与粘性物隔离，防止软包电池与粘性物直接接触。该电子设备可以是手机、平板电脑等，该电子设备还可以是其他使用软包电池的电子设备。该粘性物可以是胶带或胶水等，例如，该胶带可以是双面胶带，也可以是其他具有粘接剂的物体，便于将软包电池固定于电池仓内。
由于液体的主要作用就是能够在软包电池的外层表面固化形成一体化薄膜层的包裹膜，为了实现该目的，该液体的材料例如可以为环氧材料、聚氨酯或聚丙烯等可快速固化的单一成分的液体。该液体固化后可与软包电池的外层表面形成较好的附着效果，可以对电池形成较好的防护，使软包电池更容易拆卸。
当需要拆卸软包电池时，通过剥离包裹膜即可从电池仓中取出软包电池。剥离包裹膜 的方式可以是直接用手指剥离，或者用夹子等工具快速剥离，具体此处不作限定。
本申请实施例通过在软包电池的外层表面涂覆液体并进行固化处理，使得液体固化形成包裹膜，该包裹膜附着于软包电池的外层表面，对软包电池进行一体化包裹。然后，软包电池在与电子设备组装时，通过在包裹膜上粘贴的粘性物将软包电池安装在电子设备的电池仓内，并在拆卸时通过剥离包裹膜从电池仓中取出软包电池。由于该液体固化后形成包裹膜，该包裹膜为一体化薄膜层，该薄膜层可与软包电池的外层表面形成较好的一体化附着效果，可靠性较高，且通过在包裹膜上粘贴的粘性物将软包电池安装在电池仓内时，由于包裹膜较薄，包裹膜将软包电池与粘性物进行隔离，在拆卸软包电池时，很容易剥离包裹膜而从电池仓取出软包电池。
为了便于理解，下面对本申请实施例中软包电池镀膜及拆卸过程的具体流程进行描述，请参阅图3，本申请实施例中软包电池组装及拆卸过程的一个实施例可包括：
301、在软包电池32的外层表面完全涂覆液体31；
302、对涂覆液体31后的软包电池32进行固化处理，得到包裹在软包电池32的外层表面的包裹膜35，该包裹膜35为一体化薄膜层；
303、将软包电池32组装至电子设备的电池仓33内；
304、从电池仓33的镂空部将包裹膜35剥离，以对软包电池32进行拆卸；
305、从电池仓33内取出软包电池32。
软包电池32可以是完全涂覆液体31，也可以是局部涂覆液体31，本实施例中，以软包电池32的外层表面完全涂覆液体31为例，在软包电池32进行组装以及拆卸的过程中，首先，在液体31为液体状态的环境下，在软包电池32的外层表面完全涂覆液体31，该液体31为可快速固化的单一成分的液体31，例如，液体保护膜。该液体31的材料可为环氧材料、聚氨酯或聚丙烯等。
其次，由于液体31在常温下或在密封保存等情况下为液体状态，为了使液体31能够在软包电池32的外层表面固化凝结成包裹膜35，因此需要对喷涂液体31后的软包电池32进行固化处理。该固化处理可包括紫外光(即UV)照射固化、加热固化或湿气固化等，其中，进行固化处理时，加热的温度、加热的时间、紫外光照射的强度、紫外光照射的时间，湿气固化的湿度或湿气固化的时间等参数，可以根据实际需要进行灵活设置，具体此处不作限定。
经固化处理后，软包电池32表面的液体31固化形成一体化薄膜层的包裹膜35，该包裹膜35附着于软包电池32的外层表面。该包裹膜35可与软包电池32表面形成较好的一体化附着效果，可靠性较高。
软包电池32上的包裹膜35的膜厚是可控的，例如，若需要包裹膜35的膜厚较薄，则可少量涂覆液体31；若需要包裹膜35的膜厚较厚，则可大量涂覆液体31。为了达到利用包裹 膜35隔离粘性物34与软包电池32表面的直接接触，且尽量减少液体31的用量的目的，可以设置包裹膜35的厚度为20微米至40微米的范围内。包裹膜35越薄，软包电池32整体厚度越小。可以理解的是，在实际应用中，可以将包裹膜35的厚度设置为某个固定值，也可以将包裹膜35的厚度设置为一个范围值，例如，还可以将包裹膜35的厚度设置为10微米至60微米的范围内，或者将包裹膜35的厚度设置为30微米，具体此处不作限定。
液体31在软包电池32的外层表面固化形成包裹膜35，得到软包电池32后，此时，可以通过胶带或胶水等带有粘接剂的粘性物34，将软包电池32组装至电子设备的电池仓33内，例如，将软包电池32表面的包裹膜35与粘性物34接触，并通过粘性物34将软包电池32安装于电子设备的电池仓33内，包裹膜35将软包电池32与粘性物34隔离。
当需要对软包电池32进行拆卸时，从电池仓33的镂空部将包裹膜35剥离，即可从电池仓33内取出软包电池32。由于包裹膜35较薄，因此剥离包裹膜35的方式可以是用手指直接可快速剥离软包电池32表面的包裹膜35，取出软包电池32，使软包电池32与电池仓33无损分离，或用镊子或夹子等剥离包裹膜35取出软包电池32，剥离包裹膜35的方式还可以是其他方式，具体此处不作限定。
需要说明的是，在软包电池32的外层表面涂覆液体31，可以是在软包电池32的外层表面完全涂覆，也可以是在软包电池32外层表面进行局部涂覆，以下分别进行详细说明。
为了对软包电池32的外层表面进行全局防护，可以在软包电池32的全部外层表面涂覆液体31，该全部外层表面可以是除了软包电池32的正负触点之外的表面，如图4所示。
图4中，上部分为在软包电池32的全部外层表面涂覆液体31后，软包电池32的截面图，下部分为在软包电池32的全部外层表面涂覆液体31后，软包电池32正面示意图，即俯视图。
或者是，为了减少液体31的成本，以及方便大批量生产，可以在软包电池32的外层表面局部的预设区域内涂覆液体31，如图5和图6所示。
图5中(a)和(b)为在软包电池32的外层表面局部的预设区域内涂覆液体31后，软包电池32的截面图，图6中(a)、(b)、(c)和(d)为在软包电池32的外层表面局部的预设区域内涂覆液体31后，软包电池32的俯视图。
例如，可以是在软包电池32上相邻或任意三个面的外层表面涂覆液体31，也可以是在软包电池32上相对的两个面的外层表面涂覆液体31，还可以是在软包电池32上与正负触点表面相邻的的四个面的外层表面涂覆液体31，还可以是在软包电池与电池仓接触的其中一面外层表面涂覆液体，还可以是在相邻三个面的外层表面涂覆液体31，并在其他面上涂覆成十字或一字形的液体31。
可以理解的是，在实际应用中，为了减少液体31的成本，还可以是仅在软包电池32与正负触点表面相邻的四面的表面涂覆液体31，具体此处不再进行穷举。该液体31在软包电池32的外层表面涂覆非常方便，可实现在软包电池32表面的自动化涂覆及固化，提高了生产效率。
本申请实施例还提供了一种电池组件，该电池组件包括软包电池和包裹膜，该包裹膜包裹在软包电池的外层表面，该包裹膜采用前述图2至图6所示实施例中的电池包裹膜的形成方法制作。
本申请实施例还提供了一种电子设备，该电子设备包括电池仓、粘性物和电池组件，其中，该电池组件包括软包电池和包裹膜，该包裹膜包裹在软包电池的外层表面，该包裹膜采用前述图2至图6的电池包裹膜的形成方法制作。该电子设备可以是手机、平板电脑等。
以上对本申请实施例所提供的电池包裹膜的形成方法、电池组件以及电子设备进行了详细介绍，本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请的方法及其核心思想；同时，对于本领域的一般技术人员，依据本申请的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本申请的限制。
