电化学装置及电化学装置的制造方法
摘要：
本申请公开了一种电化学装置及电化学装置的制造方法，其中，电化学装置包括：电极组件；第一外壳，第一外壳包括融合层，融合层与电极组件接触；和第二外壳，第二外壳包括热缩包裹层，第一外壳设置于第二外壳和电极组件之间。根据本申请的电化学装置，通过使第一外壳包括与电极组件接触的融合层，并在第一外壳的外部包裹第二外壳，可以有效地包覆第一外壳，提高电化学装置使用的安全性，同时可以进一步地改善电化学装置尺寸空间利用率，提升电化学装置体积能量密度。
摘要（英）：

The application discloses an electrochemical device and a manufacturing method of the electrochemical device. The electrochemical device comprises an electrode assembly, a first shell and a second shell. The first shell comprises a fusion layer which contacts the electrode assembly. The second shell comprises a heat-shrinkable wrapping layer. The first shell is arranged between the second shell and the electrode assembly. According to the electrochemical device of the application, because the first shell comprises a fusion layer contacting the electrode assembly and is wrapped in the second shell, the first shell can be well wrapped, and the use safety of the electrochemical device can be improved. Moreover, the dimensional space utilization ratio of the electrochemical device can be further improved, and the volumetric energy density of the electrochemical device can be enhanced.
