Collection of Correct Use Methods of Digital Lithium Battery

Tips for the correct use of digital lithium batteries There are two types of lithium batteries on the market: Ni-MH batteries and lithium batteries. Lithium batteries have been batch processed liquid lithium batteries (LiB) and polymer lithium batteries (LiP). Therefore, in many cases, a lithium-ion battery must be a lithium battery. But it is not necessarily a liquid lithium battery, it can be a polymer lithium battery. Lithium batteries are an improved product of lithium batteries. Lithium batteries have been around for a long time, but lithium is a metal with high activity (remember its position on the periodic table?), it uses less safety, usually in the case of incineration, suddenly when charging, Then improve the type of lithium battery, you can add active ingredients of Gulf Lithium (such as cobalt, manganese, etc.), and then make the lithium battery really safe, effective, convenient, and then screen the old lithium battery. As for how to distinguish them, they can be identified from the battery's logo. Lithium batteries are lithium, and lithium batteries are lithium ion. Today, the so-called lithium batteries used in laptop computers and mobile phones are actually lithium batteries. The basic structure of modern batteries consists of three parts: positive electrode, negative electrode and electrolyte. As a kind of battery, lithium battery has the same three elements. Lithium-ion technology generally uses liquid or inorganic colloidal electrolytes, so it is necessary to reinforce the casing to contain combustible active ingredients, which increases the weight and cost of the battery, but also limits the flexibility of its size and shape. Generally speaking, the minimum thickness of a liquid lithium ion secondary battery is 6 mm, which is difficult to further reduce. The so-called polymer lithium battery is the first battery system in which polymer materials are used in at least one or more of three important structures. The new generation of polymer physicalization of polymer lithium batteries is now at a high level, so the shape can be thin (0.5 mm thinner), any area and any shape, which greatly improves the flexibility of the battery modeling design and can meet the requirements of the product. Produce batteries of any shape and capacity. In general, the unit energy of polymer lithium batteries is 50% higher than that of ordinary lithium batteries, and its capacity, charge and discharge characteristics, safety, operating temperature range, cycle life and environmental performance are greatly improved than lithium batteries. . In the case of overcharging, liquid lithium-ion (LiB) batteries sold on the market are likely to cause a safety valve to rupture and catch fire. This is very dangerous, so it is necessary to install and maintain IC circuits to ensure that the battery will not be overcharged. Charging scene. In terms of polymer lithium batteries, this battery has better charge and discharge resistance than liquid lithium batteries, so the external maintenance requirements for IC circuits can be appropriately relaxed. In addition, in terms of charging, polymer lithium batteries can be charged with IC constant current, which can shorten a lot of waiting time compared with lithium-ion secondary batteries using constant current-constant voltage (CCCV) charging. Mobile phone manufacturers' use of lithium batteries Although almost all manufacturers have tended to choose lithium batteries in recent years, important international mobile phone manufacturers still have their own characteristics and habits when choosing batteries. For example, in the same historical period: Nokia: Nickel metal hydride (nickel metal hydride) batteries, lithium ion (liquid lithium ion) batteries, non-lithium ion (polymer lithium ion) batteries. Ericsson: Choose Ni-MH batteries, Lithium batteries and Lithium batteries. Motorola: Use Ni-MH batteries and lithium batteries instead of lithium batteries. It is not difficult to find that Ericsson is a pioneer in mobile phone technology, using lithium-ion lithium batteries as the first choice for mobile phones. According to the materials I found, the important manufacturers of polymer lithium batteries are Japanese companies such as Sony, Panasonic, and GS. In 2000, the production and sales volume reached 21 million units, of which 50% were Ericsson mobile phones. Since 2002, lithium batteries have been widely used by other mobile phone manufacturers. However, the application of lithium-ion polymer batteries in all mobile phone manufacturers is far from extensive, and it will take some time to be widely used.
