The superbattery negative plate comprises an alloy material basal body, wherein a lead paste coating is arranged on the front of the alloy material basal body, and a carbon material coating is arranged on the back of the alloy material basal body; the thickness of the alloy material basal body is 0.01-0.5 mm; the thickness sum of the alloy material basal body, the lead paste coating and the carbon material coating is less than 1 mm; and the front of the basal body is coated by a front coating taking lead powder as a main component, and the carbon material coating takes the carbon material as the main component is coated on the back of the basal body. The superbattery negative plate disclosed by the utility model introduces a carbon layer with a double-electrode-layer structure on the basis of the traditional storage battery negative plate structure, so that the novel superbattery has high ratio power and large-current charge and discharge, reduces the sulfation of the lead paste on the front of a negative pole in HRPSOC (high-rate partial state of charge) state, and meets the HEV (hybrid-electric vehicle) application.
Description
Technical field
The utility model belongs to the Lead-acid Battery Technology field, is specifically related to a kind of Novel super lead-acid battery anode plate.
Background technology
Transportation is to cause one of greenhouse gas emission that the mankind produce and principal element of combustion of fossil fuel.Therefore for reducing the use of air pollution and fossil-fueled, the mankind are growing to the demand of hybrid electric vehicle (HEVs).Superbattery is a kind of hybrid accumulator, combines asymmetric super-capacitor and lead-acid battery in monomer, gets the chief of both technology, does not need extra electrical adjustment.Capacitor can increase power and the life-span of lead-acid battery, because the negative pole sulfation can be effectively avoided in the effect that it has played buffering when discharging and recharging.And this hybrid technology can provide rapidly, absorb electric charge when vehicle accelerates and brake.
At present, candidate's HEV energy-storage system comprises VRLA battery (VRLA), Ni-MH battery, chargeable lithium cell and ultracapacitor.Well-known ultracapacitor can provide very high power, but energy is low, if therefore will be applied to HEV, need to be combined with other battery.Compare with other technology, it is low, fixing manufacturing sales network, high-recovery of initial cost that the VRLA battery has obvious advantage.Yet the operating cost of this battery is very high, because useful life is short.HEV uses lower valve control battery must be at the 30-70%SoC(state-of-charge) lower use.Because lower than 30% the time, battery can not transmit the needed electric current of starting as SoC.On the other hand, can not effectively accept regenerative braking and engine charging when SoC battery higher than 70% time.In addition, under HEV used, the lead sulfate of negative plate (irreversible lead sulfate) was more and more.The accumulation of lead sulfate has significantly reduced the invertibity of battery, so that negative pole no longer can transmit and accept the required power of engine starting, acceleration and regenerative braking, finally causes the premature failure of storage battery.
Summary of the invention
The purpose of this utility model is to provide a kind of simple, as to have the double grading of battery and electric capacity super battery negative plate of making.
The technical solution of the utility model is achieved in that and comprises the alloy material matrix, and the alloy material front side of matrix has the lead plaster coating, and there is the Carbon Materials coating at the alloy material matrix back side.
Described alloy material matrix thickness 0.01～0.5mm.
The thickness sum of described alloy material matrix, lead plaster coating and Carbon Materials coating is less than 1mm.
Described Carbon Materials coating comprises Carbon Materials, acetylene black, bonding agent, and bonding agent is generally selected one or more in Kynoar, butadiene-styrene rubber, esters of acrylic acid adhesive, polytetrafluoroethylene and carboxymethyl cellulose.
Described lead plaster coating mainly comprises lead powder, acetylene black, barium sulfate, lignin, short fiber and bonding agent.
Substrate of the present utility model is selected the alloy material of one or more metals such as the very little lead of resistance, copper, aluminium, silver, nickel, magnesium.
Compared with prior art, the utility model is to introduce the charcoal layer with high-ratio surface on the traditional storage battery anode plate, the electric double layer of the equal and opposite in direction opposite in sign that exists on charcoal layer and electrolyte solution interface under different potentials.The utility model has the performance characteristics (for example charging rate is fast, power density high) of storage battery and capacitor concurrently, and is workable, avoids charcoal to add and causes that the loose of cathode lead plaster comes off.Can provide high current charge-discharge after being assembled into battery, avoid the sulfation of negative pole under the HEV pattern.Lightweight, specific power and the specific energy of the traditional plumbic acid of raising, and active material and the increase of substrate contacts area effectively improve active material utilization.
The electrode plate structure of the utility model battery also is applicable to the dual coating of Different electrodes material, and the positive and negative pole lead paste of traditional lead acid batteries also can be coated in respectively thin substrate both sides, is assembled into bipolar battery.
Can be assembled into super winding battery after the utility model negative plate and winding battery positive plate screw winding in addition.
The utility model super battery negative plate structure not only is applied to the superbattery assembling, equally also can be applied in assembling process in other asymmetric electrodes, such as bipolar battery.
