Cell and cell tank

Abstract

The invention discloses a cell and a cell tank for the cell. The cell is characterized in that the cell comprises a cell housing body which is a cylinder with a basic size the same as a basic size of a conventional general cylindrical cell or is an oblate cylinder formed by a way that the cylinder has a lateral offset of multiple diameters; an annular groove shape positive electrode is arranged on the top of the cell housing body; and a convex negative electrode which is the same as a negative electrode of a general cylindrical cell is arranged at the bottom of the cell housing body and is opposite to the positive electrode. The cell has a positive electrode different from a positive electrode of a general cylindrical cell thus is not easy to be misused. The cell has only a positive electrode and does not need a variable-voltage circuit thus a cost of the cell is low. The cell tank comprises a positive electrode lead unit and a negative electrode lead unit. The positive electrode lead unit is provided with cylindrical positive electrode lead pieces and annular positive electrode lead pieces, wherein the cylindrical positive electrode lead pieces and annular positive electrode lead pieces are electrically isolated. Through the cell tank, electrodes of a general cylindrical cell can be leaded out for power supply, and cylindrical electrodes or oblate cylindrical electrodes of the cell can be leaded out for power supply. The cell tank has the advantages of good compatibility and versatility.

Description

technical field [0001] The invention relates to a battery and a battery compartment structure for external power supply thereof. . Background technique [0002] There are two main types of existing batteries, one is general-purpose cylindrical batteries, which are uniform in shape and size, including No. 1, No. 2, No. 5 and No. 7 batteries, and No. 5 (AA) and No. 7 (AAA) Cylindrical batteries with a nominal voltage of 1.5 volts are the most widely used. Most of these batteries are disposable dry batteries, and there are also some nickel-cadmium and nickel-hydrogen secondary batteries (rechargeable batteries) with a nominal voltage of 1.2 volts. The other type is a special battery, which varies in shape and size depending on the manufacturer and the power-consuming product. The voltage of this type of battery is mostly 3 volts or 3.7 volts, and the lithium-ion battery with a nominal voltage of 3.7 volts is the most widely used. . [0003] General-purpose cylindrical batt...

AI Technical Summary

Problems solved by technology

However, the versatility of the square mobile phone battery is very poor. After the battery power is used up, it is impossible to buy a suitable battery conveniently. You need to find a place to charge the battery before you can continue to use the appliance.

In the case of improving the utilization rate of the battery compartment capacity, it cannot take into account the versatility

[0009] In addition, the current multi-cell battery compartment cannot provide normal power supply when only part of the batteries are installed, and only when all the batteries are installed can the normal power supply be provided, which is limited in use and inconvenient
