Analysis of lithium batteries and their advantages

Lithium battery is one of the important achievements of high-tech research in the past 10 years, and represents the advanced level of chemical power development. Because this new system has the advantages of high specific energy, long cycle life and environmental friendliness, it has become an important supporting power source for various portable electronic products. It has good advantages in mobile occasions. At present, the global annual demand for lithium batteries has been Reaching 1.3 billion, with annual sales of 27 billion U.S. dollars, it is undoubtedly one of the leaders in the rechargeable battery market. With the development of new materials for lithium batteries, the innovation of battery production technology, and the participation of many scientific research institutions and companies, the performance of lithium batteries is increasing, the cost of batteries is decreasing, and the safety performance of batteries is greatly improved. The car category is gradually showing its application advantages. Japan's Fuji Economic believes that lithium batteries will gradually replace nickel-metal hydride batteries in 2011, and that lithium batteries will be the mainstream technology route in the future. With the development and application of new materials such as nano-lithium titanate and nano-lithium iron phosphate, lithium batteries will become an ideal choice for a series of major high-tech applications such as clean transportation and photovoltaic energy storage. At present, my country’s power grid companies are actively developing 10MW lithium The experimental project of battery energy storage system will trigger a new round of investment in related manufacturing equipment and workshops. At the same time, many new manufacturers of lithium-ion power lithium-ion batteries and materials will make the technical competition in related fields more fierce and large-capacity Lithium battery energy storage power stations have gradually emerged on this basis. Advantage 1: Long life! The average life of a lithium battery is about 4 years, which is about twice that of a lead-acid battery. If it can run 50 kilometers, it can run 40 kilometers after two years. The lead-acid battery can run 30 kilometers is enough. . Advantage 2: Light! Under normal circumstances, the lead-acid battery pack weighs 16-30 kg and is relatively large; while the lithium battery generally weighs 2.5-3.0 kg and is relatively small, so it is light to ride and easy to carry. Advantage 3: Better to use! The lithium battery has good overcharge/charge and discharge resistance. Under normal temperature, the lithium battery can continue to be charged for 48 hours without any accidents such as battery expansion, leakage and breakage, and the capacity remains above 95%. And under the special charger, fast charge and discharge can be carried out, and the shock resistance is also strong.
