Technical field
The present invention relates to a kind of Lead Acid Battery Used for Electric Vehicle, be the battery technology field.
Background technology
Electric motor car as electric bicycle, electro-tricycle etc., because of characteristics such as pollution-free, energy-conservation, light, has powerful commercial viability.Lead Acid Battery Used for Electric Vehicle belongs to easily-consumed products as the main building block of electric motor car.At present, the useful life of Lead Acid Battery Used for Electric Vehicle is shorter, and only arranged 8～October, and its usage economy is poor, can not satisfy consumer's requirement far away.
Summary of the invention
Technical problem to be solved by this invention is: the Lead Acid Battery Used for Electric Vehicle that a kind of long service life is provided.
Lead-acid accumulator with long service life for electric vehicle of the present invention comprises shell, plate railings of anode and cathode, active material and electrolyte, and the weight alloy percentage composition of its anode plate grid is:
Sb 0.1～2%, Cd 0.5～2.5%, Sn 0.03～0.5%, Al 0.005～0.1%, surplus are plumbous.
Anode plate grid has been selected brand-new alloy composition for use, improve the adhesion of grid and active material, can reduce the consumption of water, suppressed positive material, overcome the short and big defective of low antimony alloy water consumption of lead-calcium alloy cycle life, the useful life of having improved storage battery.
Described lead acid accumulator is added with additive in its electrolyte, and additive component has Na 2SO 4, EDTA and EKL, be that the addition of radix is respectively with the electrolyte weight:
Anhydrous Na 2SO 40.1～2%, EDTA 0.5～2%, EKL 0.1～0.5%.
The adding of electrolysis additive has suppressed the lead dendritic crystal growth, has stoped the passivation of electrode, has reduced self discharge, has prolonged the useful life of storage battery.
Described lead acid accumulator, the weight of its positive active material consists of: different in nature carbon materials: account for lead powder weight 0.1～1.8%, the VN-1 alloy addition: account for other alloy compositions (that is: remove beyond the lead powder alloy compositions) total amount 0.1～0.5%.
Opposite sex carbon materials is the combination of a kind of in graphite, N type carbon fibre and the polymerization carbon or any two or three.As long as total amount meets the requirements.
Adopt different in nature carbon materials as positive active material, Stability Analysis of Structures is lasting, and micropore is beneficial to the diffusion of electrolyte, has very long useful life and bigger capacity.
Described lead acid accumulator, the composite diaphragm in its battery can design two-layer or multilayer, and general 2～6 layers suit.The MULTILAYER COMPOSITE barrier film has prevented the internal short-circuit of battery phenomenon, prolongs battery useful life.
The situation that the present invention is identical with regular situation is not repeated.
The present invention has carried out improving adjustment from aspects such as plato grid alloy formulation, positive active material prescription, electrolyte to storage battery, has prolonged the useful life of storage battery greatly.Doubling that the useful life of storage battery of the present invention is more original is many, and normally more than 18 months, long can use more than 2 years.Use lead-acid accumulator with long service life for electric vehicle of the present invention to reduce the use cost of electric motor car, reduced the replacing number of times of storage battery, use more conveniently, further satisfied the requirement of consumer Geng Gao.
