Lithium ion polymer battery.501825 battery

　　The battery consists of the following parts:

　　Condition: LICOO2 lithium cobalt or limn2O4 lithium manganese manganese

　　Dividation: conductive electrolytic polymer (eg, polyethylene glycol, PEO)

　　Negative electrode: Lithium or lithium carbon embedded (chemical) compound

　　Typical response: (discharge)

　　Negative poles: (Carbon-lix) → C +XLI +XE

　　Divide: li conductivity

　　Corporation: Li1oxCoo2+XLI+XE → LICOO2

　　Total reaction: (Carbon-XLI+ XE)+ Li1-XCoo2 → LICOO2+ carbon

　　Electrolytic/septum polymers can be solid polymers, such as polyethylene glycol (PEO), plus hexarin lithium potassium (LIPF6), or other conductive salt, silicon dioxide or other mechanical properties that can enhance mechanical properties Filling materials (not commercialized in this way). Under the requirements of security, the general battery uses carbon embedded lithium as a battery negative electrode, except for some manufacturers (after the merged with BATSCAP), some manufacturers use metal -state lithium negative electrodes (called lithium metal polymer battery) Essence

　　These two commercial batteries are cohesive solvents and salts such as carbonate (EC)/carbonate (DMC)/carbonate (DEC) aggregate on polytarin fluoride (PVDF) Essence The difference is that (the technology of Bellcore/Telcordia) uses the lithium permanganate (limn2O4) as the positive pole; the traditional method is to use the cobalt lithium oxides (LICOO2).

　　Although it has not yet been popularized, there are other different lithium polycies in the positive pole. For example: Moltech is developing, which is made of conductive plastic and carbon-sulfur compounds. However, by 2005, this technology seems to have a self -release problem at the same time.

　　Other methods include the use of sulfur -containing organic compounds and conductive polymers as the positive electrode, such as polyiline. This method can make good high discharge capabilities, including low internal resistance and high discharge capacity, but there are insufficient cycles and high costs
