Problems solved by technology

[0004] With this structure, if the welding time is too long or the welding temperature is too high during the welding operation, the molten lead liquid will flow into the inside of the battery, causing a short circuit between the positive and negative electrodes of the battery electrode group, causing great hidden dangers.

Abstract

The invention discloses a lead acid battery pole group assembled structure. The top of a pole group obtained by assembling a positive pole plate, a negative pole plate and a diaphragm is provided with an acid resistant netted plastic pad, small pores with the aperture of 0.5-1.0mm are uniformly distributed on the pad, and the amount of porosity of the pad is 40-60%. The structure is used for making a lead acid battery, and can prevent the contact of flow lead with the positive and negative pole plates, possibly appearing in battery terminal welding without influencing acid filling of the battery, so the internal short circuit of the battery is prevented, and the reliability and the safety of the battery are improved.

Description

technical field [0001] The invention relates to a lead-acid storage battery structure, in particular to a lead-acid storage battery electrode group assembly structure. Background technique [0002] Although lead-acid batteries have low energy and short deep-cycle life compared with lithium batteries and nickel-metal hydride batteries, due to their small self-discharge, superior high and low temperature performance, mature production and recycling technology, and low prices, this battery is still the world's leading battery. One of the largest and most versatile power sources in the world. [0003] At present, the connection of the terminals of the lead-acid battery is to weld the lead bushing embedded in the battery cover with the internal pole of the battery to form a sealed structure. [0004] With this structure, if the welding time is a little longer or the welding temperature is too high during the welding operation, molten lead liquid will flow into the battery, causi...
