In this application, the battery mentioned refers to a single physical module including one or more battery cells to provide higher voltage and capacity.

The battery cell includes an electrode assembly and an electrolyte. The electrode assembly consists of a positive electrode plate, a negative electrode plate and a separator.

The applicant found that after the battery is stored for a period of time, the electronic components inside the battery will be damaged (the battery has electronic components inside for collecting battery charging information, temperature information, etc.), affecting the service life of the battery.

After in-depth research, the applicant found that the reason for the damage to the electronic components inside the battery was that when the battery was packaged in a packaging box, it would come into contact with the side walls and top cover of the packaging box and cause friction to generate static electricity. Static electricity would destroy electronic components. This in turn affects the battery life.

In view of this, in order to improve the anti-static effect on batteries, the inventor designed a battery storage device after in-depth research. The battery storage device includes a panel, a support frame, a positioning block and a conductive piece. Support brackets support the panels. The positioning block is arranged on the panel, and the positioning block is electrically connected to the support frame through the conductive piece. That is, when the support frame is grounded, the positioning block is grounded. That is, when the battery is placed on the panel, the battery positioned by the positioning block is also grounded, so that The battery is at earth potential.

The positioning block and the support frame are electrically connected through conductive parts. When the support frame is grounded, the static electricity generated by friction on the battery surface can be transferred to the support frame through the positioning block and conductive parts, ultimately achieving reliable grounding conduction and effectively reducing the battery surface. The electrostatic value of the battery makes the electrostatic value on the surface of the battery meet the anti-static requirements of the surface electrostatic voltage being less than 100 volts, thereby reducing the risk of static electricity damaging the electronic components inside the battery and extending the service life of the battery.

The battery storage device disclosed in the embodiment of the present application includes but is not limited to storing batteries, electronic devices and other items that need to be anti-static.
