Fig. 1 is a schematic structural view illustrating a battery 100 according to an exemplary embodiment, and fig. 2 is a schematic sectional view illustrating a battery 100 according to an exemplary embodiment. As shown in fig. 1 and 2, the battery 100 may include a battery cell 1 and a casing 2, and the casing 2 may include at least a portion of the battery cell 1 to form protection for the battery cell 1. This electric core 1 can include any kind in aluminium shell electricity core, soft-packaged electric core and the cylinder electricity core, and this disclosure is not the restriction. The casing 2 may include a body 21 and a thermochromic layer 22 located on the body 21 on a side away from the battery cell 1, the body 21 may include an aluminum film layer, and the thermochromic layer 22 may change color with a change in temperature of the battery 100.

Based on this, when battery 100 leads to generating heat because of work or leads to generating heat because of charging and make body 21 surface temperature rise, the temperature sensing discoloration layer 22 that covers on body 21 surface can switch to any kind of colour according to the temperature variation that senses, for example blue, orange or yellow etc. or because the temperature that each position of temperature sensing discoloration layer 22 sensed is different, this temperature sensing discoloration layer 22 can show for the gradient, so, can not only promote scientific and technological sense, can also play the effect of the warning of generating heat. The battery 100 may include a lithium battery, among others.

In one embodiment, the thermochromic layer 22 may be made of a mixture of an ink material and a thermochromic material. For example, the thermochromic material may be mixed into the ink material at a predetermined ratio, and then the mixture may be formed on the body 21 through a printing process or a coating process after being uniformly mixed. The preset ratio may be 1: 1 or 2: 1, etc., the disclosure is not limited.

In another embodiment, as shown in fig. 3, the housing 2 may further include an ink layer 23, and the ink layer 23 is located between the thermochromic layer 22 and the body 21. Wherein, because printing ink layer 23 and temperature sensing discoloration layer 22 separate to for the technical scheme that two mix in the aforesaid embodiment, be favorable to adjusting temperature sensing discoloration layer 22's area and position, material saving satisfies the design demand more easily. In this embodiment, the ink layer 23 may be formed on the body 21 through a printing process, and the temperature-sensitive color-changing layer 22 may be formed on the ink layer 23 through a printing process or a coating process.

In the above embodiments, the dimensional specifications between the thermochromic layer 22 and the body 21 may be the same or different, and will be described below as an example.

In one embodiment, as shown in fig. 4, the edge of the thermochromic layer 22 may be flush with the edge of the body 21, and the thermochromic layer 22 may completely cover the body 21, so as to increase the area of the battery 100 that can be discolored.

In another embodiment, as shown in fig. 5, the thermochromic layer 22 may cover only a portion of the body 21, so as to save materials and reduce cost. In some cases, the body 21 may include a recess, and the thermochromic layer 22 may be embedded in the body 21 to avoid increasing the thickness of the battery 100, and in other cases, the thermochromic layer 22 may also be stacked on the surface of the body 21 to reduce the processing difficulty.

Further, as shown in fig. 5, the battery 100 may further include a battery protection board 3, where the battery protection board 3 is connected to the battery cell 1 to implement overcharge and overdischarge protection and overcurrent and short circuit protection. In fact, in the working process of the battery 100, the battery protection plate 3 also needs to be in a working state, and heat is also generated, so the temperature sensing discoloring layer 22 in the present disclosure can cover a part of the area of the body 21, which is disposed near the battery protection plate 3, which is beneficial to monitoring and reminding the temperature of the battery protection plate 3 through the color change of the temperature sensing discoloring layer 22.
