Leak-proof battery

Abstract

The invention provides an anti-leakage battery, which comprises a cylindrical casing, a battery inner core, and positive and negative electrodes; the battery inner core includes a positive electrode material and a negative electrode material; the inside of the outer casing also includes a sealed cavity; Enclosed is a conductive liquid that can move along the radial direction of the battery, and the volume of the conductive liquid is not greater than half of the volume of the sealed cavity; when the conductive liquid moves to one end of the sealed cavity, the conductive liquid is electrically The pair of conductive contacts set in the sealed cavity is electrically connected, and when the conductive liquid moves to the other end of the sealed cavity, the pair of conductive contacts are electrically isolated by the air in the sealed cavity; the positive and negative One of the electrode materials passes through the pair of conductive contacts and is connected to the corresponding electrode of the material. The anti-leakage battery can conveniently suppress the leakage current to increase the service life of the battery.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a cylindrical battery. Background technique [0002] In daily life, cylindrical batteries are the most widely used batteries, such as No. 5 batteries and No. 7 batteries; and such batteries are generally used for daily necessities such as remote controls and toys; and for electronic circuits, due to the gap between components The coupling is very tight, even if there is no output at the output end, a weak leakage current will be generated at the input end; since the working time of this kind of daily necessities is much shorter than the idle time, from a long-term perspective, this kind of leakage current will add up and will account for The relatively considerable proportion of the entire battery power leads to a significant reduction in the service life of the battery; for this reason, in the actual use process, some users will put the positive and negative poles of the battery in the ...

[0002] In daily life, cylindrical batteries are the most widely used batteries, such as No. 5 batteries and No. 7 batteries; and such batteries are generally used for daily necessities such as remote controls and toys; and for electronic circuits, due to the gap between components The coupling is very tight, even if there is no output at the output end, there will be a weak leakage current at the input end; since the working time of this kind of daily necessities is much shorter than the idle time, from a long-term perspective, this kind of leakage current will add up and will account for The relatively considerable proportion of the entire battery power causes the service life of the battery to be greatly reduced; for this reason, in the actual use process, some users will put the positive and negative poles of the battery in the battery box after the electrical appliance is used up. But this requires pulling the battery out of the battery box, which is very inconvenient. Most people seldom do this because they find it troublesome, and would rather let the leakage current be wasted
