Description
The present invention is a kind of novel organic conductor-polyaniline (PA) conductive plastic battery.Polyaniline is done the positive active material of battery, and light metal alloy magnesium is done negative pole special material alive, is a kind of storage battery of high-energy-density.
The lithium battery of present development, manufacturing process is very complicated, involves great expense, can't popularization and application.When in a single day being exposed to humid air mainly due to lithium metal, can tarnish rapidly, surface blackening has produced many to the disadvantageous compound of battery performance simultaneously, therefore need drying equipment processing metal lithium a whole set of costliness and that have inert atmosphere, the entire cell assembling process is also wanted this equipment.Because lithium metal can be rapidly with the water reaction, releasing hydrogen gas forms the solution of lithium hydroxide again.Therefore before the assembling lithium battery, also will be the strict processed of electrolyte, and also electrolyte can only be with the organic solution of non-proton property, and the output specific power of battery is just lower.And the price comparison of organic solvent is expensive.The price that adds lithium metal is also expensive.Like this, the cost of lithium battery is just very expensive, can't popularization and application.
Also have and a kind ofly make the battery of negative electrode active material with zinc, the proportion of zinc is than higher (7.14).Specific energy is just lower, the output voltage of zinc battery lower (1.4 volts), and utilance is lower.
The object of the invention is, enters commodity market in order to develop Plastic accumulator early, adopts and compares the negative plate that the much lower magnesium metal of lithium metal price is made storage battery.The whole processing technology of simple and easy conductive plastic battery.Reduce cost, make conductive plastic battery popularization and application early.
The present invention realizes like this, will through the aniline of purification in 48% fluoborate solution with electrochemical method oxidation polymerization on the nickel thin plate skeleton of 0.1 millimeters thick, just can obtain the layer/polyaniline conductive plastics, treatedly change it into neutrality, after vacuumize, just can do the anode of battery again.
Negative pole is with a slice AZ alloys magnesium, the about millimeter of thickness.

2Need to purify, and adopt distilled water to do electrolyte through distillation.
Battery diaphragm adopts the fen of treated match fine jade, as preventing that positive active material from shifting to the pellicle of negative plate, uses the polypropylene adhesive-bonded fabric as second layer barrier film again, as the material that keeps electrolyte, has improved the mechanical strength of whole barrier film.
This battery is like this by the polyaniline anode, magnesium alloy negative electrode and Mg(ClO

2Neutral aqueous solution constitute.

2The O/PA battery open circuit voltage reaches 2 volts, and its open circuit voltage of discharge back is 0.8～1 volt.The voltage of battery charging and discharging changes between 1 volt～2 volts.Just the upper limit charge value of battery is 2 volts.This battery open circuit voltage discharges and recharges between 1 volt and 2 volts 50 times back and forth, and battery still keeps good performance.This explanation is in above-mentioned voltage range.Battery in charge and discharge process anion in the doping of polyaniline electrode with go the invertibity of the process of mixing fine.It has higher active material utilization.Sharply to descend be because (after having changed the magnesium negative pole, the battery continuation can be worked well) that the corrosion of magnesium electrode causes for battery output capacity and energy after discharging and recharging for 50 times, and the decay resistance of magnesium alloy improves.
This battery is owing to adopt magnesium to do negative electrode active material.So some hysteresis.Now be controlled at about 0.1 second, this is little to general work influence.
Major advantage of the present invention: adopt novel organic conductor-polyaniline to make storage battery, brought into play the superiority of conductive plastics.No matter at the aqueous solution or in aprotic organic solvent solution, good invertibity is arranged all through the experiment polyaniline electrode, charge-discharge performance is fine.
The magnesium metal aboundresources that adopts, standard electrode EMF is more negative, and electrochemical equivalent is less again, has the good condition as the high-energy battery negative electrode active material.Magnesium metal is applicable to that also many kinds of conductive plastic batteries do negative pole.
Advantage of the present invention also has:
(1) discharging voltage balance, average discharge volt is higher 0.3 volt than zinc and polyaniline battery.
(2) because magnesium electrode utilance height, so the specific energy height of battery, be about the three to four-fold of zinc and polyaniline battery.
(3) magnesium metal proportion is 1.74, the same light metal that belongs to lithium metal.
(4) adopt the aqueous solution to do electrolyte, the specific power of battery is than higher.
(5) owing to adopt the aqueous solution to do electrolyte, adopt the magnesium metal more much lower to make negative plate, add that the cost of layer/polyaniline conductive plastics is not high again, again because manufacturing process of the present invention is extremely simple than lithium metal price.It is more much lower than lithium battery that assembly technology requires, so the cost of entire cell significantly reduces, thereby make conductive plastic battery popularization and application early.
