　　Research progress of all-solid-state thin-film CR2477 battery and characteristics of thin-film all-solid-state CR2477 battery. Using solid electrolytes to replace organic liquid electrolytes and preparing all-solid-state CR2477 battery is the fundamental way to solve the current safety problems of lithium-ion batteries. Thin film all-solid-state lithium battery is a new structure lithium-ion battery developed on the basis of traditional lithium-ion battery.

　　Research progress of all-solid-state thin film CR2477 battery

　　The key materials of thin film CR2477 battery mainly include positive electrode film, electrolyte film and negative electrode film. In thin film all-solid-state CR2477 battery, the electrolyte plays a vital role, directly affecting the charge and discharge rate, cycle life, self-discharge, safety, and high and low temperature performance of the thin film battery. Therefore, solid electrolyte films are required to have high ionic conductivity, low electronic conductivity, wide potential window, and good chemical and mechanical stability.

　　The research and commercialization of thin-film all-solid-state CR2477 battery in my country started relatively late. In recent years, the research and development and industrialization of thin-film all-solid-state CR2477 battery have been accelerating, and their corresponding application markets are also gradually expanding. Research on three-dimensional thin film CR2477 battery is still in its early stages. Most research is still in the state of conceptual design and electrode preparation. There are very few reports on complete three-dimensional thin film CR2477 battery. For all-solid-state thin-film CR2477 battery using metallic lithium as the negative electrode, the construction of the three-dimensional nanostructure of the positive electrode material is particularly important, and its performance directly determines the performance of the full battery. However, difficulties in constructing three-dimensional cathode materials have always restricted the research and development of three-dimensional solid-state thin film batteries.

　　Solid-state CR2477 battery can produce flexible and thin-film batteries, which can be applied more quickly in 3C product design. In addition, the improvement of thermal stability accelerates the application of thin-film CR2477 battery in special applications, such as implantable and intelligent medical equipment, and wireless sensors. There is a huge potential market in application fields.

　　There is still a large gap between my country's thin-film all-solid-state lithium battery technology maturity and international standards. The specific manifestations are as follows:

　　① my country’s research and development of key material systems for thin-film all-solid-state CR2477 battery started late, and in terms of large-scale preparation of thin-film batteries, design and manufacturing of battery packs, battery sealing protective layers, packaging technology, failure mechanisms, performance evaluation standards, etc. There is also a lack of systematic research;

　　② In terms of hardware such as vacuum coating equipment necessary for the preparation of thin-film batteries, as well as necessary raw materials such as sputtering targets, my country lacks relevant research and development experience compared with international companies such as Applied Materials of the United States and Aifake of Japan. Publicly reported information Very little;

　　③In terms of thin-film battery applications, foreign companies such as Cymbet have realized the application of thin-film all-solid-state CR2477 battery in micro-electronic devices. However, there are currently no thin-film battery products for sale in China, and there are no public reports on commercial applications.

　　Therefore, exploring efficient and low-cost positive electrode thick film preparation technology is the key to the further development and industrial application of thin film all-solid-state CR2477 battery in the future. With the continuous deepening of research and the continuous emergence of new technologies, it is believed that the single battery capacity and energy density of thin film all-solid-state CR2477 battery will continue to increase, the manufacturing costs will continue to decrease, and they will occupy an important place in the future secondary battery market.

　　Characteristics of thin-film all-solid-state CR2477 battery

　　Thin-film all-solid-state CR2477 battery have a perfect electrode/electrolyte solid-solid interface, which can effectively solve the safety problems of current commercial lithium-ion batteries, and have ultra-long cycle life, wide operating temperature range, and low self-discharge It has advantages such as high efficiency and superior performance compared to solid-state CR2477 battery, and has attracted widespread attention in the industry.

　　Thin-film all-solid-state CR2477 battery can be used in more harsh environments, such as higher resistance to high and low temperatures, and good performance at low temperatures of -40°C and high temperatures of 150°C, so they can be used in high-temperature detectors and oil exploration in the semiconductor industry. and space exploration.

　　The potential of the thin film electrode is uniform, and the risk of local overcharge and overdischarge of the electrode is small.

　　Summary: After years of development, thin-film all-solid-state CR2477 battery have shown superior safety, stability and electrochemical performance, and have become an irreplaceable micro power source for the new generation of microelectronic devices. The advantage of all-solid-state CR2477 battery is that the use of solid electrolytes helps improve the safety of CR2477 battery.
