Lithium ion and polymer battery What is the difference ah?
But the current domestic polymers are false polymers, the real polymer battery electrolyte is solid, such as Sanyo Sony ATL huge electronic polymer is called polymer
Lithium polymer battery (Li-polymer) is a lithium-ion battery based on the polymer polymer electrolyte to replace the traditional liquid organic electrolyte produced. This polymer electrolyte can be used as a conductive ion medium, but also can be used as a separation film, coupled with the lithium metal reactivity is very low, so effectively avoid the lithium ion battery easy to burn and easy to leak phenomenon. And since the lithium ion polymer battery is a liquid organic electrolyte adsorbed on a polymer matrix, it is called a colloidal electrolyte, which is neither a free electrolyte nor a solid electrolyte, so that the lithium lithium polymer battery not only has Liquid lithium-ion battery of excellent performance, can also be made into any shape and size, ultra-thin products, making its wide range of applications, good prospects for development. Another security than the lithium-ion battery is good, the use of if the heat, will only produce swelling or burning and will not explode.
Disadvantages are security, because the metal shell seal is good, the use of the battery may be explosive explosion risk.
Lithium-ion batteries are typically lithium-free. At the time of charging, lithium ions are driven from the positive lattice, driven by an electric field, and are embedded in the negative lattice through the electrolyte. Discharge, the process is just the opposite, lithium-ion return to the cathode, the electron is passed by the electrical, from the external circuit to the positive and lithium-ion composite. As the lithium-ion battery does not contain any precious metals, raw materials are very cheap, price space is large, should be the cheapest battery.
Lithium-ion battery negative is a carbon material, such as graphite. The positive electrode is a lithium-containing transition metal oxide, such as LiMn2O4. The electrolyte is an organic solution containing lithium salts.
