2 built-in battery, Built-in battery, there are two forms of closure, ultrasonic welding and packages labeled (using the battery all wrapped trademark)
Ultrasonic welding battery mainly: NOKIA 8210,8250,8310,7210 and so on.The subject of the battery pack on a lot, such as the first two years of very waterside MOTO998, 8088 a.Section II lithium-ion batteries the basicsLithium-ion battery cell is a new energy, it does not contain lithium, in the charge-discharge process, only the lithium ions between the positive and negative movement between the electrode and the electrolyte does not participate in the reaction.

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.
