Lithium ion battery principle:lithium batteries, lithium ion batteries, lithium polymer battery, people are often those with the lithium battery make impossible things, for lithium ion battery principles necessary that become the key to solve this confusion, because in all of these involve "lithium battery" theory, the principle of lithium ion battery is a throughout the three link, have the function of the future.
Lithium ion battery principle 1. Firstly, we should clarify the three concepts that we first proposed. In the history of lithium batteries, the first stage is a lithium battery, the battery cathode is lithium metal, and on this basis, the second stage developed a rechargeable lithium battery, namely theory in the sense of lithium ion batteries, lithium rechargeable lithium battery is not exist, only the lithium ion battery. Because of the different lithium compounds and electrolytes as the positive electrode materials, there are lithium ion battery principles based on different materials. In recent years, Fishing lithium battery pack it is often said that the lithium polymer battery is on the basis of liquid lithium ion battery, which it the presence of lithium battery into the third stage, due to the lithium polymer battery is lithium ion battery electrolyte by improvements to the solid or liquid state gel batteries, therefore, it is not out of the working mechanisms of lithium ion battery principle system, but improve the principle of lithium ion batteries.
Lithium ion battery principle 2, secondly, lithium battery pack factory should understand the principle of lithium ion battery in structure. Generally speaking, the lithium ion battery has five parts: the positive and negative, diaphragm, organic electrolyte, shell, in the principle of lithium ion batteries, the diaphragm is the most technical content of manufacturing, while depending on the liquid or polymer electrolyte are different.
Lithium ion battery principle 3, from the principle of understanding on the mechanism of lithium ion battery and lithium ion battery principle is embedded lithium ion compound as the anode material of battery, in this sense, as long as it is the working mechanism of lithium ion battery, whether liquid or polymer, and is creating many battery manufacturer of power battery, are applicable to general principle of lithium ion batteries. In the principle of lithium ion battery, the battery charging process is the embedding and deembedding process of lithium ions, and the lithium ion deinlaid when charging, which is embedded in the cathode through the electrolyte. When discharging, the opposite is true.
Understand the above principle of lithium ion battery, finally can use an image of the metaphor as a knot, people usually use "rocking-chair batteries" as a description of the principle of lithium ion battery is lithium ion has been "the positive and negative and the positive" motion state, make the lithium ion battery is like a rocking chair, rocking chair across the electrodes at both ends for battery, lithium ion is that movement in both ends of the "people", the metaphor from the mechanism principle of lithium ion batteries.
