To bull him hard again, could not squeeze a drop of milk to. Rechargeable lithium rechargeable lithium species, such as lithium - vanadium oxide batteries, lithium ion batteries and lithium newly developed abroad - polymer batteries. Here only the first two, focusing on lithium-ion batteries. Rechargeable lithium-ion battery is currently the most widely used mobile phone batteries, but it is more "delicate" in use can not overcharge, over discharge (may damage the battery or make it scrapped). Therefore, the battery protection circuit protection components or to prevent costly damage to the battery. Lithium-ion battery is demanding, to ensure that the termination voltage accuracy within 1%, the current major semiconductor device factory has developed a variety of lithium-ion battery charging IC, in order to ensure safe, reliable, and fast charging. Now the phone is very common, the phone is part of the nickel metal hydride batteries, but the smart phone is a type of lithium ion battery. Proper use of lithium-ion batteries to extend battery life is very important. 1. a lithium - vanadium oxide cells (Li-V6O13) lithium - lithium vanadium oxide cell anode, vanadium oxide cathode, an organic solvent, an inorganic salt electrolyte composition. It features can be charged. In the 2nd battery, for example, the lithium - vanadium oxide battery and lithium - manganese dioxide batteries and lithium - thionyl chloride batteries compared as shown in Table 5. As apparent from Table 5, since the lithium - vanadium oxide battery rated voltage is only 2.8V, and the rated capacity is also small, as compared with the other two lithium batteries, which is the minimum specific energy. The main parameters of such cylindrical battery is shown in Table 6. As can be seen from Table 6, the charging times (cycle life) is not long, so this rechargeable battery soon replaced by a lithium-ion battery. 2. The lithium-ion battery (Li-Ion) Lithium-ion battery is currently the most widely used lithium batteries, which according to the requirements of different electronic products can be made into a flat rectangular, cylindrical, rectangular and button, and there are several battery connected together in series to form a battery group. Lithium-ion battery is rated at 3.6V (some products for 3.7V). When fully charged, the battery termination voltage anode material related to: the anode material is graphite 4.2V; anode material for the coke 4.1V. Resistance of different anode materials are also different, slightly larger than the internal resistance of the anode coke, the discharge curve is slightly different, as shown in FIG. Commonly referred to as 4.1V and 4.2V lithium ion batteries lithium ion battery. Lithium-ion battery termination discharge voltage 2.5V ~ 2.75V (battery factory operating voltage range is given or termination of the discharge voltage is given, the parameters are slightly different). Lower than the termination of the discharge voltage continues to discharge as over-discharge, over-discharge of the battery will be damaged. Lithium ion batteries are not suitable for high current discharge, will reduce the discharge time is too large current discharge (internal temperature will result in higher energy loss). Therefore, the battery production plant gives maximum discharge current, in use should be less than the maximum discharge current. Lithium-ion batteries have certain requirements for temperature, factory gives charging temperature range, the discharge temperature range and storage temperature range. Lithium-ion battery charging requirements are very high, it requires sophisticated charging circuit to ensure safe charging. Termination voltage accuracy tolerance of the nominal ± 1% (for example, 4.2V rechargeable lithium-ion battery, which tolerance is ± 0.042V), over-voltage lithium-ion battery charging can cause permanent damage. Lithium-ion battery charging current battery manufacturing plant should be based on the recommendations and requirements in order to avoid current limiting circuit overcurrent (overheating). Commonly used charging rate 0.25C ~ 1C (C is the battery capacity, such as C = 800mAh, 1C charging rate i.e. charging current 800mA). When large current charging tend to detect the battery temperature to prevent overheating damage the battery or an explosion. Lithium-ion battery is divided into two phases: the first constant current charge was changed to near end voltage constant voltage charging, the charging characteristics shown in Figure 2. This is a 800mAh capacity battery, which terminates the charge voltage of 4.2V. Batteries 800mA (charging rate of 1C) constant current charging, the battery voltage at the beginning of a larger slope boost when the battery voltage is close to 4.2V, 4.2V changed to constant voltage charging, current gradually decreased, the voltage changes little, the charge current is reduced to 1 / 10C (about 80mA), it is considered nearly full, it can terminate charging (some charger after 1 / 10C start timer, over a certain time after the end of charge).
