Summary of the invention
The technical problem to be solved in the present invention is the deficiency that overcomes prior art, a kind of charge acceptance and dark circulation discharge performance that can improve battery is provided, the communication valve-control sealed lead acid battery positive electrode active materials that be fit to big electric current, recycles deeply, and the preparation of this material and the curing behind the smear are provided.
Technical scheme of the present invention is: communication valve-control sealed lead acid battery positive electrode active materials, comprise lead powder, adhesive, sulfuric acid and deionized water in the component, its improvements are to add the lead sulfate catalyst in the component, the mass percent of each component is: lead powder 80～85, adhesive 0.1～3, density is the sulfuric acid 3～8 of 1.30～1.40g/ml, deionized water 5～10, lead sulfate catalyst 3～8.
Communication with the preparation method of valve-control sealed lead acid battery positive electrode active materials be get the raw materials ready by the mass percent of each component after, lead powder, adhesive and lead sulfate catalyst are fully mixed 10～15min under dry state, in 5～7min, at the uniform velocity add deionized water again, stir while adding, add the back and continue to stir 5～10min, the sulfuric acid that adds density 1.30～1.40g/ml again, adding the acid time is 10～15min, add the acid back and continue to stir 10～15min, control and cream temperature are lower than 80 ℃ in the preparation process.
Communication is that this active material is being cured behind the smear under 50～60 ℃ of temperature in three stages with the curing of valve-control sealed lead acid battery positive electrode active materials, phase I: 74～82 ℃ of temperature, humidity 95～100%, time 8～10h, second stage: 64～70 ℃ of temperature, humidity 75～85%, time 18～25h, phase III: 55～60 ℃ of temperature, humidity 60～70%, time 10～12h.
The present invention as a kind of crystal seed, forms the heterogeneous mixture that cell electrochemical reaction is used owing to add the lead sulfate catalyst, and the four basic lead sulphate ratios that form in the lead plaster are increased considerably, and reaches 2-3 times of prior art.Stir in the preparation fully, mix, again by three stage solidification technologies, shortened curing time, improved solidification effect, the crystalline solid that forms is the homogeneous mixture of four basic lead sulphates and tribasic lead sulfate, and four basic lead sulphate content reach more than 70%, and the active material after solidifying is organized tiny even, combine closely on the grid rib, keep good bonding force, specific area increases, the adhesion of enhanced activity material and grid and the uniformity of active material, improve the electrode charge and discharge performance, help improving the charge acceptance of battery, prolong the dark cycle life of battery, be applicable to big electric current, deep discharge recycles.
Embodiment
Further specify the present invention below by embodiment:
The component and the mass percentage content of example one, example two active materials are:
The preparation method of example one, example two active materials is: after getting the raw materials ready by each constituent mass percentage, lead powder, adhesive and lead sulfate catalyst are mixed 10min (example one) or 15min (example two) under dry state, in 6min, at the uniform velocity add deionized water again, the limit edged stirs, add the back and continue to stir 6min (example one) or 8min (example two), add sulfuric acid again, adding the acid time is 10min (example one) or 15min (example two), the limit edged stirs, add the acid back and continue to stir 15min (example one) or 10min (example two), control and cream temperature are 70～75 ℃ in the preparation process.
The smear temperature of example one, example two active materials and three stage solidification methods are as follows:
With the resulting active material of example one make pole plate routinely the technology assembling change into and make 9 of GFM-500 battery samples, carry out charge acceptance and cycling life test respectively, the 12V250A storage battery circulating inspector that checkout equipment adopts Zhangjiagang Jin Fan Electrosource, Inc. to produce.
1, charge acceptance test
From the sample battery, extract 3 batteries, respectively with 50A current discharge 5h, put into 0 ℃ low temperature chamber 25h again, taking-up is in 1min, and 2.35V charges to storage battery with constant voltage, behind the 10min, record maximum charging current and be respectively 200A, 212A, 215A, and the prior art maximum charging current has only about 100A, and manufactured samples charging current of the present invention is more than 2 times of prior art, and charge acceptance obviously improves.
