Zinc and manganese batteries are the original battery with manganese dioxide as the positive electrode, zinc as the negative electrode, and ammonium chloride aquatic solution as the main electrolyte.Commonly known as dry battery.It is also known as the Leklang Xie battery in the academic world.

Zinc -manganese battery principle
The alkaline manganese battery is an upgraded high -performance battery product for ordinary dry batteries, including LR6 (No. 5) and LR03 (No. 7) batteries.The products are divided into ordinary types (0.60%of mercury content) and micro -mercury volume (mercury content is not greater than 0.025%).The following is the reaction of the alkaline zinc manganese dry battery.Positive extremely cathode reaction: MNO2+H2O → MNOOH8MNOOH has a certain solubility in alkaline solution MNOOH+H2O8 → Mn (OH) 4-Mn (OH) 4- → Mn (OH) 42-negative anode reactions: Zn+2OE-→ zn (oh) 2
Zinc -manganese battery structure
① manganese dioxide (manganese powder): As an active substance for the positive electrode of zinc -manganese battery, it is an important raw material that directly participate in the electrode response and determines the battery charge.② Graphite: It is also one of the raw materials of the positive pole.It is divided into two types: display crystal (scales) and hidden crystal type (earth -shaped).③ Acetylene Black: It is also a material in the positive electrode, which is similar to graphite.However, its proportion and particles are small. Although the conductivity is secondaryly in graphite, the water absorption and decentralization are far beyond graphite.④ Zinc: It is as important as manganese powder. Zinc is an active substance for battery negative electrodes.⑤ ammonium chloride: the main component of the electrolyte of zinc -manganese battery.⑥ Zinc chloride: belongs to the normal material in the electrolyte.⑦ Flour and starch: Since they are the main substances that form "outer membrane protection", it is natural to protect the role.
