[ background of the invention ]

The principle of the polymer lithium ion battery is the same as that of liquid lithium, and the main difference is that the electrolyte is different from the liquid lithium. The main structure of the battery comprises three elements of a positive electrode, a negative electrode and an electrolyte. The polymer lithium ion battery is a battery system in which a polymer material is used as a main battery system in at least one or more of the three main structures. In the polymer lithium ion battery system developed at present, the polymer material is mainly applied to the positive electrode and the electrolyte. The positive electrode material includes conductive polymer or inorganic compound used in common lithium ion battery, the electrolyte can be solid or colloidal polymer electrolyte, or organic electrolyte, and common lithium ion technology uses liquid or colloidal electrolyte, so that a firm secondary package is required to contain combustible active components, which increases weight and limits size flexibility.

In the processing operation of the lithium battery, on-off detection operation needs to be performed on the finished lithium battery, that is, whether the battery can perform discharge conduction is detected. In the conventional operation of detecting the on-off state of the lithium battery, the universal meter is manually connected with the positive electrode and the negative electrode of the battery, and then judgment is carried out according to data displayed on the universal meter.
