Problems solved by technology
[0003] The technical problem to be solved by the present invention is to provide a safe rechargeable lithium battery structure. By improving the structure of the lithium battery, it simplifies the operation of the lithium battery when it is placed, thereby effectively solving the problem of the increased NTC of the lithium battery. pole alignment issues at the output and affect operating efficiency
It improves the structure of the lithium battery pack, as long as the positive and negative electrode structures that are easy to recognize in shape can be placed in the battery compartment, and there is no need to carefully identify the NTC pole and negative pole, which reduces the need for lithium battery packs. The operation when placed, thus effectively solving the problem of pole alignment and affecting the operating efficiency of the lithium battery pack due to the increased NTC output

Embodiment Construction
[0015] Below by specific embodiment, in conjunction with accompanying drawing, the technical solution of the present invention is described in further detail:
[0016] see figure 1 and figure 2 , a safe rechargeable lithium battery structure, including a battery cell 51, a negative thermistor 52 (NTC) installed close to the battery cell 51, a positive terminal, a negative terminal and a packaging case. The exterior of the battery is packaged in a cylindrical shape, the positive pole 53 of the battery is drawn out from the top of the shell, and the negative plate 54 and NTC pole 55 of the battery are drawn out from the bottom of the shell. Wherein, the negative pole at the bottom of the casing is arranged in the center of the casing, and the NTC pole 55 is in a ring shape and concentrically surrounds the negative pole 54 around the periphery of the negative pole 54, and each pole is separated by an insulating sheet. When using lithium batteries with this structure, it is onl...

The invention discloses a safe rechargeable lithium battery structure, which includes a battery cell, a casing and a thermistor (NTC) arranged in the battery casing; the lithium battery is cylindrical; a positive electrode is arranged on the top of the lithium battery, and The bottom end of the lithium battery is provided with a negative pole and an NTC pole; the negative pole and the NTC pole are arranged in concentric circles. It improves the structure of the lithium battery pack, as long as the positive and negative electrode structures that are easy to recognize in shape can be placed in the battery compartment, and there is no need to carefully identify the NTC pole and negative pole, which reduces the need for lithium battery packs. The operation during placement effectively solves the problem of pole alignment of the lithium battery pack due to the increased NTC output and affects the operating efficiency.
Description
technical field [0001] The invention relates to a cylindrical lithium battery, in particular to a lithium battery structure used in medical equipment and medical equipment using the lithium battery. Background technique [0002] The existing 18650 cylindrical lithium-ion batteries are widely used in digital electronic products such as notebook computers, mobile DVDs, and various small medical devices. In existing applications, 18650 lithium-ion batteries are usually connected in series and parallel with multiple cells and connected to the protective circuit board (PCB board) using power cables or connected in series and parallel as a battery module to form a specific shape to suit various applications. electronics needs. As disclosed on February 12, 2014, the Chinese invention patent application with the publication number CN103567349A discloses a control and protection circuit for a lithium electric riveting gun, which includes a main control single-chip microcomputer modu...
