so the lithium-ion batteries more secure and stable. The reaction schematic and basic reaction is as follows:Lithium-ion batteries can reach an energy density capacity 300Wh / L, weight capacity density can reach 125Wh / L.Second, the construction of batteries, LiCoO2 positive electrode of batteries plus conductive agent and a binder, coated on the aluminum foil forming the positive electrode plate, a negative electrode conductive agent is added graphite layered adhesive tape coated on the copper base, a more advanced anode layered graphite particles has adopted the nano-carbon. According to the above reaction mechanism, positive use of LiCoO2, LiNiO2, LiMn2O2, LiCoO2 which is a layer structure of the crystal form is stable, but away from the LiCoO2 XLi, its structure may change, but is changed depending on X size. Through research found that when X> 0.5 when Li1-XCoO2 showed extremely unstable structure, crystal paralysis collapse occurs, the external manifestations of batteries overwhelming end. Therefore, the batteries in the course of the charging voltage should be controlled by limiting Li1-XCoO2 the X value, the charging voltage is generally not more than 4.2V then X is less than 0.5. then the crystalline Li1-XCoO2 remained stable. C6 cathode itself has its own characteristics, the first time after formation, the positive electrode LiCoO2 Li C6 is charged to the negative electrode, when the discharge cathode LiCoO2 Li back, but it must be followed by a part of Li into left in the negative C6, , the heart in order to ensure that the next embedded in the normal charge and discharge Li otherwise overwhelming batteries is short, in order to ensure a portion to remain in the negative electrode C6 Li, in general, by limiting the discharge lower limit voltage to be achieved.
