What is a dry cell, what is a lithium battery, why are cell phones are using lithium batteries, rather than dry cells?
Dry cell batteries
Dry cell batteries also become voltaic batteries, voltaic batteries are said to be made of multiple sets of round plates appear in pairs and stacked in a certain order, round plates with two different metal plates, a layer of cloth between the classes to play a conductive role, dry cell batteries are made according to this principle, dry cell batteries have a paste-like substance inside, some of which is gelatin. Therefore, its electrolyte is paste, and this kind of battery disposable battery, after discharge cannot be recharged, zinc-manganese dry cell electric potential of 1.5V, if you charge the phone, at least need more than one dry cell.
We often see five and seven batteries, one battery and two batteries with relatively less, this battery is mainly in the wireless mouse, alarm clock, electric toys, computers, radio applications more, we are more familiar with Nanfu battery, which is a famous battery company in Fujian.
Li-ion battery
The solution inside the lithium battery is a non-aqueous electrolyte solution, the negative electrode material is made of lithium metal or lithium alloy, so the difference with the dry cell is that the battery internal reaction material is different, while the charging characteristics are different, lithium batteries can be cyclically charged. Lithium batteries generally have lithium metal batteries as well as lithium ion batteries, two kinds of such batteries in cell phones, electric cars, small household appliances, cell phones, notebooks, electric shavers and a large number of applications, more widely used than dry cell batteries.
Lithium batteries and dry cell battery comparison:
1. Dry cell batteries are disposable batteries, lithium batteries belong to rechargeable batteries, can be recharged in many cycles, and no memory, do not need to be charged according to the amount of power, with the use of.
2. Dry cell batteries are very polluting, many batteries used to contain mercury, lead and other heavy metals, serious environmental pollution, because they are disposable batteries, soon used up and discarded, but lithium batteries do not contain harmful metals.
3. Lithium batteries also have a fast-charging function, cycle life is also very high, which is unmatched by dry batteries, and now many lithium batteries will have internal protection circuit.
