Abstract:

Electrochemical energy storage is a key technology to achieve low-carbon electricity system. With the rapid growth of energy storage station construction, safety issues also became prominent gradually. In the past decade, several fire and explosion accidents occurred in energy storage stations around the world, illustrating the urgent requirement of safer, more efficient and stable operation. Lithium-ion energy storage system with high safety and reliability is an inevitable choice for the development of the power industry. Present monitoring technology based on module level has met its limitation on efficient early warning, requiring the development of new intelligent sensing techniques. Integrated sensing techniques at the cell level is an effective way to enhance the safety and stability of energy storage lithium-ion batteries. Integrated sensing techniques based on cell level can obtain internal information of battery, including temperature, strain, pressure, and gas, which would be useful for early warning, early isolation, and early handling. This review systematically introduced the difficulties, challenges, and latest progress of this advanced technology, from the following three aspects. To achieve accurate measurement, sensors need to solve the contradiction between long lifetime and electrochemical corrosion inside battery. To meet successful implantation, the contradiction between need for integrated sensors and stable working battery during its lifetime needs to be solved. To realize signal transmission, sensing signals need to solve the contradiction between effective transmission and electromagnetic shielding of battery case. The applications of integrated sensing technology in early warning of thermal runaway and electrochemical characteristics with all lifetime have further prospected.

Key words: lithium ion battery, integrated sensor, internal signal, signal transmission, electromagnetic shielding
