Introduces the characteristics of lithium battery, charging characteristics and usage

Source: 2020 - 04 - 19 then hits: lithium-ion batteries can be used as a variety of electronic equipment is used for dc power charge for many times. Through the related comprehensive evaluation, the lithium battery has small volume, light weight, large capacity, environmental protection, more circulation, etc. Now has become a mainstream batteries, lithium-ion batteries many lithium battery manufacturer can produce this kind of battery. The following article introduces the characteristics of the lithium battery, charging features and using method, do a detailed instructions for you. Lithium battery characteristics of lithium ion batteries are divided into liquid lithium battery and lithium polymer battery, the liquid is a kind of secondary batteries, lithium-ion batteries with lithium ion the positive and negative. LiCoMo2 lithium compound as cathode, cathode for lithium compound between carbon layer. Lithium battery there are generally two kinds of shapes: cylindrical and square. Battery internal is spiral, by a very delicate, polyethylene film isolation of permeable material, insulation material between the positive and negative. The anode made of lithium cobalt oxide and aluminum foil cathode is mainly composed of carbon graphite materials. Inside the battery is full of organic electrolyte solutions, and install the security element, to protect the battery when abnormal situations and short circuit output from being damaged. 3. 7 v lithium-ion batteries in general, if a single battery, voltage control in 3. 7 v, within no more than the voltage range. As a result, a single lithium batteries are often series parallel processing, in order to meet the needs of different occasions. Lithium battery rechargeable characteristics of 1. Do not contain lithium: that does not contain batteries, lithium metal, so there is no ban on plane carrying lithium battery. 2. No pollution: lithium-ion batteries do not contain harmful metals such as cadmium, lead, mercury. 3, high cycle life: under normal circumstances, can continue to use more than 500 times, if you use the lithium iron phosphate can be used more than 2000 times. 4, high energy density: in terms of weight, also have greatly improved, lighter, if use lithium-ion batteries, and other similar capacity of nickel cadmium battery weight is about half of them. Lithium battery capacity for 20 - nickel metal hydride battery capacity 35-30%, nickel metal hydride battery capacity 50%. 5. High pressure: as I mentioned earlier, if it is a single lithium-ion battery, work environment is the most appropriate voltage in 3. Less than 7 v, compared with other types of batteries, it will have more advantages, basically the equivalent of three series of nickel cadmium battery or nickel metal hydride batteries. 6. Over discharge resistance: when a discharge, excess lithium ion fell from the electrode, lead to the collapse of the lattice, shorten service life. Of lithium-ion batteries used in 18650 lithium battery lithium ion batteries anode to form, and is moving through the electrolyte to the anode. Carbon as anode, with layered structure, it has many holes, has good effect to enlarge the capacity. Another important thing is, if we use lithium electronic in discharge, which means that the equipment in the work, the cathode carbon layer of the lithium ion can be directly move back to the anode. The greater the cathode for lithium ion, the discharge capacity. Lithium battery manufacturer, therefore, it is recommended that you in charge must be used when special constant current constant voltage charger.
