The most famous is the standard battery-Houston, sub-saturated and unsaturated-two. Its standards for EMF 1.01864 V (20 ℃). Non-saturation of the saturation voltage-temperature coefficient of about 1 / 4.
Paste-zinc - manganese batteries
Zinc from cones, paste layer, manganese dioxide as cathode, the carbon rods, copper caps, and other components. Most outside layer is a tube of zinc, it is the battery anode and Jianzuo containers, in the course of discharging it to be gradually dissolved; Central is a set flow from the role of the carbon rod; tightly around the root of this is a carbon rod From dark brown or black manganese dioxide powder and a conductive material (graphite or acetylene black) posed by a mixture of it with carbon rod with a battery of the cathode, also known as carbon package. To avoid the evaporation of water, batteries with the top or asphalt sealing wax. Zinc - manganese batteries work for the zinc electrode reaction is: Zn → Zn2 + +2 e
Cardboard-zinc - manganese batteries
In paste-zinc - on the basis of manganese dry batteries from improving. It thickness of 70 to 100 microns in non-metallic impurities in the high-quality kraft paper-based, with good mash-coating the surface, made of cardboard again after drying, to replace the zinc-paste - manganese dry batteries in Electrolyte layer cake. Cardboard-zinc - manganese batteries of the actual discharge capacity than ordinary zinc-paste - manganese batteries to be higher than the 2 to 3 times. Marked "high performance" on the batteries for the vast majority of cardboard.
Alkaline zinc - manganese batteries
Electrolyte from its amalgam of zinc powder, 35 percent of the potassium hydroxide solution with some of the sodium carboxymethyl cellulose paste from. Since potassium hydroxide solution of the lower freezing point, the resistance of small, alkaline zinc - manganese dry batteries in temperatures of -20 ℃, and to large current discharge. Alkaline zinc - manganese batteries can charge and discharge cycle 40 times, but the charge can not be carried out before the depth of discharge (to retain 60% to 70% of capacity), and the need to strictly control the charge current and charge end-voltage.
Laminated zinc - manganese batteries
Several compact from the flat-shaped battery stack with a single. Every single cell by the plastic, zinc skin, conductive film and paper divide, carbon cake (cathode). Divide paper is a suction that the electrolyte layer of the surface starch slurry of paper, paste it in the skin of zinc above; divide carbon paper is above the pie. Divide paper-like paste, paste layer of dry batteries, zinc Paper isolation from the anode and cathode the role of carbon cake. Laminated zinc - minus the manganese dry batteries Cylindrical batteries in series-paste composition of trouble, its compact, small size, volume ratio of large capacity, but shorter storage life and the resistance of larger and therefore should not be too large discharge current.
Alkaline batteries
And the lead-acid batteries with the capacity compared to its small size, long life, to the current discharge, but the high cost. Alkaline battery materials into the plate of iron-nickel, nickel-cadmium, silver zinc batteries, and other series. Nickel-cadmium batteries as an example, alkaline batteries is the working principle: battery plates of the active substance in the charge, the cathode plate for nickel hydroxide [Ni (OH) 3], anode plate for the metal cadmium (Cd); and discharge Terminated, positive change for the plate-nickel hydroxide [Ni (OH2)], to change negative plates cadmium hydroxide [Cd (OH) 2], Electrolyte more choice of potassium hydroxide (KOH) solution.
Metal - air battery
To the oxygen in the air as a cathode active material, metal as a negative activity of a high-energy battery material. The metal is generally the use of magnesium, aluminum, zinc, cadmium, iron, etc.; electrolyte for the solution. zinc-air battery which has become a mature product.
Metal - air battery has a high ratio of energy, it is because air is not included in the weight of the batteries. zinc-air battery of energy than is now the highest in the production of batteries, has reached 400 kilowatt hours / kg (Wh / kg), is a high-performance batteries in power, and high-power battery positive direction. The current production of the metal - air battery is a battery; Development of secondary metal - air batteries for the replacement of metal electrodes used mechanical rechargeable battery. As metal - air battery work to continue to supply the air, so it can not be sealed in the state or the lack of air environment. In addition, the battery in the electrolyte solution vulnerable to the impact of air humidity battery performance decreased oxygen in the air through the air will spread to metal electrodes and electrode, the formation of corrosion from the battery self-discharge.
