Analyze lithium batteries and their uses

What is a lithium battery and its use? A lithium battery is a battery in which lithium metal or lithium alloy is used as the positive electrode material and a non-aqueous electrolyte solution is used as the electrolyte. It is the battery with the highest energy density and the best overall performance in the secondary battery technology. Since the establishment of the company, the market share has increased year by year. Compared with other rechargeable batteries, lithium batteries have the advantages of high energy density, high voltage, long life, and no memory effect. Following LEDs, lithium batteries have become another industrial product that has won the Nobel Prize for Applied Technology. UBS New Energy Fund Manager Shi Cheng said that at present, lithium batteries have become an important carrier of industrial civilization. From mobile phones and laptops to today's electric vehicles and energy storage products, the core of energy supply comes from lithium batteries. In the future era of clean energy, the storage and application of electric energy cannot be separated from lithium batteries. According to the application situation, lithium batteries can be divided into three categories: consumer lithium batteries, power lithium-ion batteries and energy storage batteries. Consumer-grade lithium batteries are mainly used in products such as 3C. In recent years, as the global rise of smart phones and other products has slowed, the rise of consumer-grade lithium batteries has narrowed. The industry generally believes that power lithium batteries are an important driving force for the rise of the lithium battery market in the future. According to the data of OFweek Industry Research Center, my country's lithium battery industry has maintained a rapid rise in 2018. The annual lithium battery market has exceeded 100GWh, a year-on-year increase of 34%, mainly due to the rapid rise of power lithium-ion batteries. Guotai Junan believes that power lithium-ion batteries have become the largest application area. Stimulated by the subsidy policy, my country's new energy automobile industry has shown a trend of rapid development. Since the State Council announced the 'Energy-saving and New Energy Automobile Industry Development Plan' in 2012, financial subsidies, tax reductions and other measures have enabled my country's new energy automobile industry to flourish. At the same time, considering my country's complete industrial chain layout and material advantages in the field of power lithium-ion batteries, my country's new energy vehicle sales have always been in a leading position in the world. In 2018, my country's new energy vehicle sales reached 1.256 million units, a year-on-year increase of 61.7% and 16 times that of 2014. From January to August 2019, the cumulative sales of new energy vehicles reached 793,000, a year-on-year increase of 32%. With the gradual cancellation of financial subsidies, my country's two-point policy will further guide the development of new energy vehicles from the perspective of marketization. Globally, developed countries such as Germany and Sweden have announced a timetable for banning fuel vehicles. At the same time, traditional time-honored automobile companies such as Mercedes-Benz and Toyota are also increasing their layout in the field of new energy vehicles. In the current era of energy reform, the electrification of automobiles has become a general trend. In recent years, my country's lithium battery industry has developed rapidly. According to statistics from my country's Chemical Industry (Cuba 601117) and Physical Power Industry Association, my country's lithium battery operating income was 172.7 billion yuan in 2018, an increase of 8.7% from 2017's 158.9 billion yuan. The output of lithium batteries increased by 23.1% from 100.9 GWh to 124.2 GWh. At the same time, the lithium battery industry chain is relatively complete. Wind Information said that 92 listed companies are involved, from upstream raw materials to downstream batteries. Lithium iron phosphate battery power lithium ion battery lithium iron phosphate battery power lithium ion battery lithium iron phosphate battery refers to a lithium battery with lithium iron phosphate as the negative electrode material. Lithium battery anode materials mainly include three materials: lithium cobalt, lithium manganese, and lithium nickel, and lithium iron phosphate. The full name of lithium iron phosphate battery is lithium iron phosphate battery, but the name is too long. Lithium iron phosphate battery. Because its performance is particularly suitable for power applications, the word power was added to its name, that is, lithium iron phosphate power lithium-ion battery. It is also called a lithium iron battery. The requirements for rechargeable batteries are: high capacity, high output voltage, good charge and discharge cycle performance, stable output voltage, high current charge and discharge, electrochemical stability, safe use (no combustion or explosion due to improper operation, such as overload, overload , Short circuit), wide operating temperature range, non-toxic or less toxic, no pollution to the environment. Lithium iron phosphate batteries use lithium iron phosphate as the positive electrode and have good performance requirements, especially in terms of discharge rate (5-10c discharge), stable discharge voltage, safety (no combustion, no explosion), life (cycle times), and no pollution to the environment etc. It is the best high-current output power battery.
