Lithium-ion batteries, especially can easily support a short, heavy equipment, such as digital camera demand at present, and they stay a longer time than alkaline battery voltage is higher.

Lithium - manganese battery: let's learn about the types of lithium batteries. Lithium-ion battery is currently the most used lithium button cells (as early as we called mercury batteries because of pollution and capacitance of the property has been gradually replaced by lithium manganese - formula) basic voltage of 3.0 V, the highest electric capacity is 1200 mAh. This battery can be designed to be lightweight, and the condition of high capacity. With stable discharge curve, which is used so many high-tech products such as the motherboard to when memory backup battery. In addition, is designed to be cylindrical lithium-ion battery has high capacity, low internal resistance, can instantly release large current, is the excellent choice of camera battery market. However, because of its raw materials for lithium metal has the very high chemical activity, therefore should not be used too much in the same cell, to avoid the risk of explosion.

Lithium - manganese dioxide battery through special craft processing of manganese dioxide as positive electrode active material, with high potential, high specific energy of metal lithium as negative active material, electrolyte using organic electrolyte solution conductive performance is good, the battery structure with full seal and seal of two kinds of forms. Of course, the security of the whole sealing and shelf life should be better than half seal.

Lithium - lithium manganese dioxide battery cathode is the positive active material is manganese dioxide. Electrolyte is inorganic salt lithium perchlorate (LiClO4), soluble in propylene carbonate (PC) and 1, 2 - dimethoxy ethane (DME) in the organic solvent mixture, its chemical formula is:

Li/LiClO4 (-) - PC + DME/MnO2 (+) battery cathode reaction: the positive reaction: Li - Li++ e MnO2 + Li++ e - MnO2 (Li +) overall reaction: Li + MnO2 - MnO2 (Li +)

Reaction mechanism of lithium - manganese dioxide battery is different from general battery, in non-aqueous organic solvent, the cathode lithium dissolved under the lithium ions through the electrolyte into the lattice of MnO2, generate MnO2 (Li +).Mn by + 3 + 4 price reduction for the price, its crystal structure does not change.

Lithium, atomic number 3, the first primary group is located in the periodic table of the first, in the known the lightest metal atomic weight of (6.94), the most negative electrode potential (3.045 V), the element's name comes from Greek, meaning "stone". In 1817 by a Swedish scientist put WeiCong through lithium feldspar found in analysis. Due to its most negative potential, with the appropriate matching of battery cathode material has superior performance. Lithium - series of lithium manganese dioxide battery is a battery in the lowest price, security, the best varieties of battery. Open circuit voltage at around 3.3 V, the load voltage at 2.8 V, the nominal voltage of 3.0 V, the voltage is 2.0 V, stable discharge voltage, suitable for high power discharge.
