Background

Lead-acid batteries have been in history for over 150 years since the world, have become secondary batteries with the largest output and the widest application in the current chemical power supply due to the advantages of low price, mature technology, reliable performance and the like, and have been widely applied to various fields such as national defense, aviation, communication, transportation and the like for a long time.

The lead-acid battery mainly comprises a positive plate group, a negative plate group, a partition plate, a container, electrolyte and the like. Lead acid batteries are often required to avoid being bumped during handling or placement. However, in real life, the lead-acid battery is often easy to fall or collide, and because the shell strength of the lead-acid battery is low, especially the bottom surface and the battery pack contact surface are easy to break, the battery is directly scrapped, and even safety accidents can be caused.

For example, chinese patent application publication No. CN101877389A, published as 2010.11.03, discloses a battery case in which a plurality of cells are arranged through partitions interlaced vertically and horizontally, and the length direction of the cells is overlapped with or parallel to the width direction of the case; the width direction of the unit cell is coincident with or parallel to the length direction of the shell. The defects of the storage battery shell are as follows: the plastic shell has low structural strength around, and is very easy to break after falling or colliding, thereby directly causing the battery to be scrapped.
