Exhaust type acid and flame resistant lead acid storage battery used for electric road vehicles

Abstract

The invention relates to a designing and manufacturing method of an exhaust type acid and flame resistant lead acid storage battery having the advantages of high specific energy, long life, fast charging and no corrosion and used for electric road vehicles. The charging and discharging states and the temperature changes of all 2V single batteries of a 2-48V storage battery are timely monitored through improving the design of the case-lid structure of the lead acid storage battery, the single batteries are connected through adopting whole metallic lead sleeve inserts pre-injected into a battery lid, the bottom of the battery is not provided with a saddle, exhaust plugs are provided with acid and explosive resistant devices, positive and negative electrode plates are designed to be paste type thin electrode plates to substitute thick tubular positive electrode plates, a separation plate can individually adopt an ultrathin glass fiber separation plate or a PE separation plate or combines the ultrathin glass fiber separation plate with the PE separation plate, and an electrolyte adopts a colloidal electrolyte. The above designing and manufacturing method can ensure a case that the storage battery is not detonated by an open fire in the use process, equipment corrosion of acid mist and caused environmental pollution to be eliminated, a rated capacity C3 value to be reached after 1h rapid charging, charging of the battery to be completed within 3h, and the storage battery to have the characteristics of high specific energy, deep cycle and long life.

Description

technical field [0001] The present invention relates to the development of exhaust-type acid-proof explosion-proof lead-acid batteries with high specific energy, deep cycle, long life and fast charging for electric road vehicles (electric cars, electric tricycles, forklifts, sightseeing cars, police patrol cars, etc.) The design and manufacturing method, especially the charging and discharging state and temperature change of each 2V single battery of the 2-24V overall battery pack can be monitored in a timely manner. There is no acid mist corrosion during use, no pollution to the environment, and no external fire. cause the battery to explode. Background technique [0002] Lead-acid battery is a kind of "resource recycling" energy product with high safety, stable electrical performance, low manufacturing cost, wide application fields, and low-cost renewable utilization. Over the past ten years, with the development of the world's energy economy and the improvement of people...

Problems solved by technology

[0008] The manufacturing process of this tubular positive plate battery is complicated, especially the “powder filling” process of the positive plate, the lead dust and noise pollution in the workplace are particularly serious, and it is easy to cause lead poisoning of workers

This type of battery has low volume specific energy and weight specific energy, small capacity, poor high-rate discharge performance, and acid mist is removed during use, which not only corrodes vehicle equipment but also pollutes the environment.
