Description
Technical field
The novel carbonaceous battery lead plate that relates to a kind of lead-acid battery of present technique belongs to field of chemical engineering.Be expected to be applied to the lead-acid battery in fields such as electric motor car, electric tool, pulse emission.
Background technology
The energy is the basis of human society survival and development, has represented the course of development in science and technology to the utilization of electric energy from the natural mineral reserve energy.Modern age; the last century quick development of human society particularly; make the human resource consumption sharply increase; cause to be becoming tight traditional fossil energy day of oil; and cause air pollution serious all the more, seek sustainable development approach, protect national resource and natural environment becomes the serious challenge of 21 century.Electric energy has become the energy of the indispensable a kind of cleaning of human society, and any other utilization of resources generally all must be used electric energy, and battery/capacitance technology is all used in the storage of electric energy, conversion, conveying.
Electric automobile (comprising pure electric vehicle and hybrid electric vehicle HEV) is pollution-free, use cost is low and be expected to the tuning network system paddy electricity at night, becomes the development trend of present research focus and future transportation instrument.Lead-acid battery application promise in clinical practice is arranged, but its specific power shortcoming low, that cycle life is short has restricted its application in electric motor car at present because of characteristics such as its raw material resources are abundant, cheap, preparation, service procedure maturation and fail safe are good in electric motor car.Ultracapacitor (Supercapacitors) is a kind of novel energy-storing device of performance between traditional capacitor and battery, its specific energy is 20～200 times of traditional capacitor, specific power is higher than general secondary cell generally greater than 1000W/kg, cycle life (＞10
5Inferior) also be better than battery, also have advantages such as the energy instantaneous large-current discharges and recharges, operating temperature range is wide, safe, pollution-free, thereby have the potential application foreground on electric automobile.But up to now, the specific energy of electrochemical capacitor still is lower than secondary cell, has restricted its application in electric motor car.
The specific power of lead-acid battery is lower and the following life-span of high power discharge is poor, mainly be to be subject to negative pole: under the high-density current discharge scenario, negative pole produces a large amount of lead ions and enters electrolyte, situation on the other side is a sulfate ion diffusion limited in the electrolyte, cause the lead ion supersaturation, form the lead sulfate beds of precipitation of one deck densification easily in negative terminal surface, cause the negative terminal surface passivation.The lead sulfate poorly conductive, solubility is little, can reduce the inner plumbous reactivity of negative pole, increases the reaction overpotential, and liberation of hydrogen is comparatively serious when causing charging, and charge efficiency descends, and forms vicious circle.As if continuing high-power discharging and recharging, above situation can further worsen, and increase of lead sulfate deposit seed and process are irreversible, final negative pole forfeiture reactivity, battery failure (referring to J.PowerSources 133 (2004) 126).If can be by the control of external circuit, avoid that lead-acid battery is high-power to discharge and recharge, can effectively improve its life-span.Chinese patent 200620097371.7 discloses a kind of battery, its in traditional battery loong shunt the capacitor that anti-high power discharges and recharges, with battery and capacitor fixing, constitute the combination of a kind of battery-electric capacity by a shell.Though such battery-electric capacity combination has been carried out combination with lead-acid battery and ultracapacitor, but belong to outer composite type, two power supplys all need electrolyte, barrier film separately etc., not only the device cumulative volume is bigger, also need external circuit and corresponding management system to carry out real-time testing, control, cost is higher.
If " outward also " of ultracapacitor and lead-acid battery made into " also interior ", then can save complicated external circuit and control system, effectively reduce cost.Chinese patent 200810136333.1 discloses a kind of lead-acid battery, and the negative level of its part stereotype is replaced by carbon plate, can improve the lead-acid battery specific power, extending battery life.Chinese patent 200910002836.4 discloses the battery with ultracapacitor activated carbon electrodes and plumbous negative pole " also interior ", and also the someone is referred to as " superbattery " (Ultrabattery is referring to J.Power Source 174 (2007) 16) in the recent period.This battery is fused to the high-specific-power of ultracapacitor, long-life advantage in the lead-acid battery, when keeping improving power, extending battery life advantage, can simplify circuit again, improve specific capacity, and reduce total cost (referring to " the science news commentary " special column in " science Times " on August 14th, 2009).
But above-mentioned superbattery is owing to reduced lead negative, and this volume of battery specific energy will descend to some extent.In addition, all be equipped with barrier film between carbon plate electrode and the lead-acid battery electrode, barrier film thicker (millimeter level) causes the active material amount of fill to reduce on the one hand, has reduced the specific energy of device; On the other hand, the adding of barrier film and carbonaceous electrode has also hindered the transmission of electrolyte ion in the charge and discharge process, because no matter barrier film still is carbon resistance rod inside micron-sized hole (yardstick 1～5 μ m, referring to Solid StateIonics 179 (2008) 1946) all there is a shortcoming that the liquid storage amount is little, the ion migration resistance is big, this has not only reduced the specific power characteristic of device, also causes the life-span decay because of the lead ion migration is limited.
If adopt the carbon plate electrode directly is attached to method on the lead-acid battery electrode, though can save barrier film, the carbon resistance rod internal particle is arranged closely, and the situation of obstruction ion transfer is still serious.
