Description
Technical field
The present invention relates to accumulators, especially relate to a kind of accumulator for photovoltaic energy storage.
Background technology
For traditional accumulator, usually cycle-index and " floating charge " service life defines its index.For power
For battery, cycle-index is current most important evaluation criterion, and the life of storage battery of photovoltaic is not achieved 1000
It is secondary.This is because in solar energy photovoltaic system, electric current, the voltage of solar energy generation change with Changes in weather.?
The energy of " entrance " (accumulation of energy) is variation, and the electricity of " going out " (use) is fixed.Therefore, it is very easy to just generate
The phenomenon that " cross and put " and " overcharging " or " charge less ".It crosses after putting, the lead sulfate that white is generated in acid accumulator is attached to electric power storage
The hard crystalline solid of one layer of white is formed on the surface of pond both inner pad, still cannot remove polar board surface is converted into work after charging
The lead sulfate of property substance, discharge and recharge reaction：
Charging reaction：PbSO4+2H2O+PbSO4→PbO2+2H2SO4+Pb
Exoelectrical reaction：PbO2+2H2SO4+Pb→PbSO4+2H2O+PbSO4
The density of traditional battery liquid is proportional to discharge capacity.Proportion when being discharged completely according to accumulator and
Proportion when 10% electric discharge, can extrapolate the discharge capacity of accumulator.When discharge capacity increases, internal driving increases, and electric discharge is bigger, resistance
It is anti-bigger.Generated in discharge process, in pole plate electric current non-conductor --- lead sulfate is all led in the proportion of whole electrolyte
Cause the increase of internal driving.Electric discharge and charging every time, will all generate new lead sulfate, are referred to as sulfation.And in the sun
The scrambling to charge every time under energy photovoltaic environment, the too early phenomenon for causing sulfation to generate, than in fixed charge and discharge
It will seriously much under environment.So accumulator its service life ratio other fixed currents, the voltage to be charged by photovoltaic
The accumulator of intensity charging greatly shortens.
From the foregoing, it will be observed that existing solar-energy photo-voltaic cell in charge and discharge, due to the unstability of solar energy electric current, that is, generates
Frequently " charge less ", " cross put ", are easy to lead to sulfation, are that adhere to one layer of white on inside battery pole plate hard
Lead sulfate crystalline solid, even if polar board surface still cannot be removed in charging process is converted into active lead sulfate, so as to cause
Battery capacity reduces and the lost of life.

Specific implementation mode
To illustrate the thought and purpose of the present invention, the present invention is done further below in conjunction with the drawings and specific embodiments
Explanation.
Referring to Fig.1-3, a proposition specific embodiment of the invention, a kind of accumulator for photovoltaic energy storage, including outside battery
Shell 30, the electrolyte being filled in inside battery case 30 are set to 30 inside of battery case and are in contact just with electrolyte
Pole plate and negative plate 10, negative plate 10 include lead substrate 14, be disposed with from outside to inside outside lead substrate 14 metallic sodium layer 11,
Magnesium metal layer 12 and metal copper layer 13.If by outside lead substrate 14 be arranged the stronger metal layer of dried layer reproducibility, by outside to
It is inside followed successively by metallic sodium layer 11, magnesium metal layer 12 and metal copper layer 13, for accumulator when carrying out charge and discharge, preferential consumption is located at lead
Metal layer outside substrate 14 is followed successively by the metallic sodium of monovalence, the magnesium metal of divalent and the metallic copper of divalent, reduces plumbite
Generation, while avoiding consumption of the accumulator when in use for lead substrate 14, improve the service life of accumulator.
Meanwhile the metal ion after reaction can be recycled repeatedly in oxidation-reduction process, can't form crystallization, to
The generation for avoiding sulfation extends the service life of battery.Because will produce after metallic sodium, magnesium metal and metal reaction
Corresponding metal ion, and above-mentioned metal ion is more active than lead, and metal ion constantly reacts with sulfuric acid successively,
Cause lead sulfate to be difficult to be formed, has achieved the purpose that reduce lead sulfate formation, while improving service lifetime of accumulator.
Specifically, 14 thickness of lead substrate is 10-20mm, if 14 outside setting of lead substrate or the upper dried layer reproducibility of plating are stronger
Metal layer, in accumulator cell charging and discharging, the preferential metal layer consumed outside lead substrate 14, when the metal layer of outside is exhausted
Later, lead substrate 14 works as the negative plate 10 of accumulator, substantially prolongs the service life of accumulator.
With reference to figure 3, rubber seal is provided on the gap between the top and battery case 30 of positive plate or negative plate 10
Pad 40 is provided with the poly- charcoal lipid layer 20 of heat cure, 20 sealed envelope positive plate of poly- charcoal lipid layer and negative plate on rubber gasket 40
10 40 top of outside and rubber gasket.The present embodiment is illustrated with negative plate 10, in battery case 30 and 10 pole of negative plate
Rubber gasket is set on the gap of column, then coats poly- charcoal lipid layer on rubber gasket, subsequently by poly- 20 heat cure of charcoal lipid layer,
The sealing of pole can be completed, and 20 heat cure speed of poly- charcoal lipid layer is efficient soon, and the sealing of battery can be rapidly completed, and protects
Card sealing is intact.
Specifically, electrolyte includes brilliant network nanometer silene and nano level graphene acid solution.Brilliant network nanometer silene is added
Afterwards, electrolyte can be become gelling solution, changes the characteristic of electrolyte so that electrolyte temperature is not easy to rise in accumulator
It is high.Because the temperature raising of electrolyte can cause the concentration of sulfuric acid to increase, sulfation is higher in electrolyte temperature
It is more prone to, after brilliant network nanometer silene is added, electrolyte temperature is not easy to increase, and then the concentration of sulfuric acid is not easy to increase,
The formation speed of lead sulfate is enabled to obviously to weaken.Meanwhile nano level graphite olefin(e) acid is added, synthetic network nano-silicon can be matched
Alkene effectively improves the service life of accumulator.
Wherein, brilliant network nanometer silene a concentration of 4% to 7%, nanoscale graphite olefin(e) acid solution concentration are 0.5% in electrolyte
To 2%.
In the present embodiment, brilliant network nanometer silene a concentration of 5.6% in electrolyte, nanoscale graphite olefin(e) acid is molten in electrolyte
Liquid a concentration of 0.8%.
In an alternative embodiment of the invention, brilliant network nanometer silene a concentration of 6% in electrolyte, nanoscale graphite in electrolyte
Olefin(e) acid solution concentration is 1.2%.
If this programme is followed successively by metal from outside to inside by the way that the stronger metal layer of dried layer reproducibility is arranged outside lead substrate
Sodium layer 11, magnesium metal layer 12 and metal copper layer 13, for accumulator when carrying out charge and discharge, preferential consumption is located at the gold outside lead substrate
Belong to layer, the metal ions such as sodium, magnesium, copper after reaction are more active in the electrolytic solution, can prevent generate can not inversion plumbic acid
Salt can be recycled repeatedly since each metal ion species are in oxidation-reduction process, will not form crystallization, can be effectively improved
Service life of battery；Brilliant network nanometer silene and nano level graphene acid solution is added in the electrolytic solution simultaneously, electrolyte is become
Agglutination solution, avoid because temperature increase and largely lead to the problem of plumbite, improve the service life of accumulator with
It is merely a preferred embodiment of the present invention, is not intended to limit the scope of the invention described in upper, it is every to utilize explanation of the invention
