Through the optimization of the battery and a power management system, the energy density of a lithium ion battery device is improved to some extent in recent years, but the energy density is close to the theoretical limit of the current material system. Among them, the lower theoretical specific capacities of graphite negative electrodes and lithium titanate negative electrodes (graphite: 372 mAh/g, lithium titanate: 175 mAh/g) are one of the main reasons for the above bottlenecks.
Meanwhile, rapid development in the fields of Micro-Electro-Mechanical systems (MEMS), active or semi-active radio frequency identification systems, internet of things, and the like, also puts higher demands on corresponding power supply systems. For the above systems, in order to improve power efficiency, reduce system size and noise interference, a micro-battery that can be integrated in a micro-system is required, which should have a size that can be matched with a micro-circuit device and a fabrication process that is compatible with an integrated circuit process. Meanwhile, the development of wearable equipment further requires that the battery device has the characteristics of bending resistance, small thickness and high specific capacity. Based on the above requirements, the preparation of self-supporting thin film electrodes by thin film deposition processes has been widely studied and implemented to a certain extent as an attractive solution.

Therefore, the use of antimony selenide as a new generation lithium storage negative electrode is a very promising solution. In recent years, researchers have conducted a lot of research on antimony selenide negative electrodes, but all of them adopt a similar preparation strategy, i.e., synthesizing antimony selenide material by chemical reaction, mixing with carbon-based material, conductive agent, and binder, and coating the electrode. Although the above strategy can improve the lithium storage performance of antimony selenide to a certain extent, the following disadvantages are present: (1) the preparation process is complex and takes long time, long-time synthesis and multiple times of vacuum drying are needed, and the preparation process is difficult to be compatible with the integrated circuit process; (2) the introduction of the low-capacity carbon-based material and the additive reduces the effective content of antimony selenide, so that the capacity loss of the electrode is caused; (3) the non-conductive binder increases the internal resistance of the electrode and cannot realize high-rate charge and discharge.
