具体实施方式
电池具有轻量化、安全性高、能量密度高等优点，故而成为大部分电子设备的首选，电子设备包括设备本体，电池装配在设备本体中，电池与设备本体电连接，并为设备本体提供能量来源。
相关技术中，电池包括壳体、电芯模组、正极转接片、负极转接片、封装片和极柱等，电芯模组包括电芯、正极耳和负极耳，壳体具有腔体，电芯模组、正极转接片、负极转接片、封装片和极柱均位于腔体中，壳体上开设有注液口，电解液通过注液口注入腔体中。
装配时，正极耳和负极耳分别连接在电芯上，正极转接片焊接在正极耳上，负极转接片焊接在负极耳上，通常情况下，为了避免正极转接片和负极转接片接触而造成短路的风险，往往在正极转接片和负极转接片之间装配有绝缘件进行绝缘，其中，绝缘件大多选用隔膜或者绝缘胶。
然而，当采用隔膜进行绝缘时，由于隔膜比较软，装配时，隔膜与极耳之间、以及隔膜与转接片之间容易存在有间隙，当转接片和极耳焊接压紧时，容易导致转接片和极耳之间、以及正极转接片和负极转接片之间接触而造成短路的风险，另外，即使在焊接的过程中没有发生短路，当电池发生震动时也会存在极大的风险导致电池短路。
当采用贴绝缘胶的方式进行绝缘时，由于绝缘胶比较薄而且强度较弱，当转接片和极耳焊接压紧时，比较容易出现极耳或者转接片划伤隔膜的情况，从而导致转接片和极耳之间、以及正极转接片和负极转接片之间接触而造成短路的风险。
同时，由于绝缘胶较为柔软，在粘贴时的操作难度较大，比较浪费人力、物力等，极大的降低了生产效率；另外，胶纸较薄，较难开设有注液口，从而对电芯的注液起到一定的阻碍效果。
为了解决上述技术问题，本申请提供一种电池及电子设备，通过包括壳体，壳体具有腔体，电芯模组、第一转接件、第二转接件和隔离件均位于腔体中，腔体能够对上述结构起到防护的作用；通过包括隔离件，且隔离件位于第一转接件和第二转接件之间，从而有效确保第一转接件和第二转接件之间的绝缘效果，避免第一转接件和第二转接件相接触而导致短路的风险，从而较好的保证电池的安全性能，进一步提升电池的质量，延长电池的使用寿命。
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请的一部分实施例，而不是全部的实施 例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请所保护的范围。
图1为本申请实施例提供的电池的结构示意图一，图2为本申请实施例提供的电池的结构示意图二，图3为本申请实施例提供的电池的分解示意图，图4为本申请实施例提供的隔离件的结构示意图，图5为本申请实施例提供的电池的剖面图，图6为图5中I部分的局部放大示意图。
