[0019] The technical scheme in the utility model will be described clearly and completely in combination with the drawings in the utility model, and additionally, the form of each structure recorded in the following implementation is only an example, and the utility model is not limited to each structure recorded in the following implementation, all other implementation obtained by the ordinary skill in the art without making creative labor belongs to the range of the utility model protection.

[0020] Embodiment one

[0021] REFERENCE Figures 1-3The utility model provides an alkaline battery with anti-short circuit, including a battery body 1 and a protective sleeve 2, which is sleeved on the outside of the battery body 1. The protective sleeve 2 is sleeved on the outside of the battery body 1 so that the protective sleeve 2 protects the battery body 1, thereby preventing the battery from being damaged and reducing the occurrence of short circuits in the battery. A graphite rod 8 is provided in the battery body 1, and the top end of the graphite rod 8 extends out of the battery body 1. A positive electrode cap 6 is provided on the top of the graphite rod 8. An anti-short circuit component is provided between the graphite rod 8 and the positive electrode cap 6 to connect the graphite rod 8 and the positive electrode cap 6. During the installation of the battery body 1, if the positive electrode cap 6 contacts the positive electrode, the anti-short circuit component will prevent the battery from short circuiting, thereby preventing the battery from rapidly heating, expanding or even exploding, thereby improving the safety of the battery.

[0022] In the utility model, in this embodiment, the anti-short circuit component is a thermistor 7, which is arranged between the positive cap 6 and the graphite rod 8, and the thermistor 7 is electrically connected to the positive cap 6 and the graphite rod 8. During the installation of the battery body 1, if the positive cap 6 contacts the positive electrode, the resistance of the thermistor 7 will increase and block the current, so that the current in the battery body 1 cannot be conducted to the positive cap 6 through the graphite rod 8. An insulating box 5 is provided on the top of the battery body 1, and the positive cap 6 and the graphite rod 8 are both located in the insulating box 5. The insulating box 5 can prevent the hand from getting an electric shock when taking the battery, thereby ensuring the safety of the battery when taking it. The protective cover 2 includes an insulating layer 4 and an anti-oxidation coating 3. The anti-oxidation coating 3 is arranged on the circumferential outer wall of the insulating layer 4. The anti-oxidation coating 3 can increase the antioxidant ability of the protective cover 2 and improve the service life of the protective cover 2.

[0023] The working principle of this embodiment is as follows: when in use, the protective sleeve 2 is put on the outer side of the battery body 1, so that the protective sleeve 2 protects the battery body 1, thereby preventing damage to the battery, reducing the occurrence of battery short circuits, and further improving the safety of battery use. During the installation of the battery body 1, if the positive electrode cap 6 contacts the positive electrode, the resistance of the thermistor 7 will increase and block the current, so that the current in the battery body 1 cannot be conducted to the positive electrode cap 6 through the graphite rod 8, thereby avoiding the occurrence of battery short circuits, preventing the battery from rapidly heating, expanding, or even exploding, and improving the safety of battery use.
