Research progress on all solid-state thin-film lithium-ion batteries and characteristics of thin-film all solid-state lithium-ion batteries. The use of solid electrolytes instead of organic liquid electrolytes to prepare all solid state lithium-ion batteries is the fundamental way to solve the current safety issues of lithium-ion batteries. Thin film all solid state lithium-ion batteries are a new type of lithium-ion battery structure developed on the basis of traditional lithium-ion batteries.

Research progress in all solid state thin film lithium-ion batteries

The key materials for thin-film lithium-ion batteries include the positive electrode membrane, electrolyte membrane, and negative electrode membrane. In thin-film solid-state lithium-ion batteries, electrolytes play a crucial role, directly affecting the charging and discharging rate, cycle life, self discharge, safety, and high and low temperature performance of thin-film batteries. Therefore, solid-state electrolyte films require high ion conductivity, low electronic conductivity, wide potential window, and good chemical and mechanical stability.

The research and commercialization of thin-film solid-state lithium-ion batteries in China started relatively late. In recent years, there has been an accelerating trend in the research and industrialization of thin-film solid-state lithium-ion batteries, and their corresponding application markets are gradually expanding. The research on three-dimensional thin-film lithium-ion batteries is still in its early stages, and most of the research is still in the conceptual design and electrode preparation stage. There are very few reports on complete three-dimensional thin-film lithium-ion batteries. For all solid state thin film lithium-ion batteries using metallic lithium as the negative electrode, the construction of three-dimensional nanostructures of the positive electrode material is particularly important, as its performance directly determines the performance of the entire battery. However, the difficulties in constructing three-dimensional cathode materials have always constrained the research and development of three-dimensional solid-state thin film batteries.

Solid state lithium-ion batteries can be used to prepare 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 lithium-ion batteries in special application fields, such as implantable and intelligent medical devices, wireless sensors, etc., which have a potential huge market.

There is still a significant gap in the maturity of thin-film solid-state lithium-ion battery technology in China compared to international standards, specifically manifested as:

① China started relatively late in the research and development of key material systems for thin-film solid-state lithium-ion batteries, and there is also a lack of systematic research in the large-scale preparation of thin-film batteries, design and manufacturing of battery packs, battery sealing and protection layers, packaging technology, failure mechanisms, performance evaluation standards, and other aspects;

② In terms of hardware such as vacuum coating equipment necessary for the preparation of thin film batteries, as well as raw materials such as sputtering targets, China lacks relevant research and development experience compared to international companies such as Applied Materials in the United States and Aifa Technology in Japan, and there is very little publicly reported information;

③ In terms of thin-film battery applications, foreign companies such as Cymbet have achieved the application of thin-film solid-state lithium-ion batteries in micro electronic devices. However, there are currently no available thin-film battery products for sale in China, and there have been no public reports on their commercial applications.

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

Characteristics of thin-film solid-state lithium-ion batteries

Thin film all solid state lithium-ion batteries have a perfect electrode/electrolyte solid-solid interface, which can effectively solve the safety issues of current commercial lithium-ion batteries. They also have advantages such as ultra-long cycle life, wide temperature range, and low self discharge rate. Compared with bulk solid-state lithium-ion batteries, they have superior performance and have received widespread attention in the industry.

Thin film solid-state lithium-ion batteries can be used in more demanding environments, such as stronger resistance to high and low temperatures, and good performance at low temperatures of -40 ℃ and high temperatures of 150 ℃. Therefore, they can be used in high-temperature detectors, petroleum exploration, and space exploration in the semiconductor industry.

The potential of the thin film electrode is uniform, and the risk of local overcharging and over discharging of the electrode is low.

Summary: After years of development, thin-film solid-state lithium-ion batteries have demonstrated 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 lithium-ion batteries is that the use of solid electrolytes helps improve the safety of lithium-ion batteries.
