Alkaline batteries are the most successful high-capacity batteries, is also one of the best price-performance batteries. Alkaline battery uses manganese dioxide as cathode, the zinc anode, electrolyte of potassium hydroxide. It features an extra heavy duty of superior, capacitance.
Alkaline battery in structure Shang used Yu General battery instead of electrode structure, increases has positive and negative very between of relative area, and with high conductive sexual of hydrogen oxidation potassium solution alternative has ammonium chloride, and zinc chloride solution, anode zinc also by tablets shaped change into granular, increases has anode of reaction area, coupled with used has high performance of electrolytic manganese powder, so electric performance to is large improve, General of, equal model of alkaline battery is General battery of capacity and discharge time of 3-7 times, low temperature performance both gap more large, Alkaline batteries are more applicable to large current discharge and requires high voltage electricity, especially suitable for camera, Flash, shavers, electric toys, CD player, high power remote control, wireless mouse, keyboard, and so on.

Rechargeable alkaline zinc-manganese battery available through the charge repeated use of an improved alkaline zinc manganese battery, known as RAM. Structure and manufacturing processes of this type of battery and alkaline zinc manganese battery is basically the same.
For implementation may then charging, the battery in alkaline zinc manganese battery of Foundation Shang for has improved: 1.improve cathode structure, improve cathode ring strength or joined viscosity received agent, additives, prevent cathode in charging and discharging Shi occurred dissolved expansion; 2.through cathode doping, improve II oxidation manganese of reversible sexual; 3.control anode activity substances zinc of dosage, control II oxidation manganese only to 1 electronic discharge; 4.improved isolation layer, prevent battery charging Shi produced zinc branch Crystal penetrating isolation layer occurred short circuit.
Rechargeable alkaline zinc manganese battery charging and discharging cycles of performance difference comparing to traditional secondary battery, charging and discharging system of battery cycle life influence greatly. At present, the full charge and discharge cycle life is only about 50 times. Is not available when using this type of battery discharge, cycle of shallow discharge can be greatly improved battery life. Reaction and in alkaline zinc manganese battery discharge a battery the same charge discharge reactions of inverse reaction occurs:
MnOOH+Zn(OH)2→Zn+MnO2+H2O
Due to shorter battery cycle life, development is constrained, only United States, and Canada’s large-scale production of several companies, also produced that type of battery in China, but production and exports is smaller.
