What's the difference between a cardboard cell and a paste cell?
Zinc manganese battery is also called leclain Agency (Leclanche) battery, is the French scientist leclain Agency (Leclanche) was invented in 1968 by zinc (Zn) as anode and manganese dioxide (MnO2) as cathode, electrolyte solution with neutral ammonium chloride (NH4cl) and zinc chloride (Zncl2) aqueous solution, the surface of starch or pulp layer of paper isolation layer made of battery called zinc manganese battery. It is also called zinc manganese dry cell because its electrolyte solution is usually made of gel or adsorbed on other carriers. According to the use of isolation layer is divided into paste and plate type battery two, plate and according to electrolyte liquid, ammonium and zinc type batteries, cardboard batteries two kinds.
Depending on the isolation layer. A cardboard cell with cardboard as insulation; a paste cell with a starch paste as an isolating layer.
The structure of the paperboard battery in the common manganese zinc dry cell is superior to that of the paste battery, and the utilization ratio of the active material is high. However, our country produces dry batteriesAbout 70% of them are still paste batteries that have been eliminated by developed countries. China's total production in 1998 about 9 billion paste batteries, to conservativeTo estimate (using a cardboard cell instead of 1.5 paste batteries), if all of them are cardboard batteries, only 6 billion would be enough, and alkalineThe battery has better performance, an alkaline battery top and 5-8 paste batteries. Developed countries have basically achieved cardboard batteries, and heThe alkaline battery of high performance batteries in the proportion of stem cells (about 4080%) is far greater than in China (about 5%). Paste of our countryBattery production in flood, is a waste of resources, and pollution is serious, should be limited and should be eliminated, the prescribed number of years.
