“…While during cycling with an upper cut-off voltage of 5.5 V severe degradation over the first 20 cycles was observed, cycling to lower cut-off voltages (1.4 V) showed improved cycling behavior when the upper cut-off voltage was set to 5.0 V. The battery had a capacity of about 170.7 𝜇Ah cm −2 µm −1 (362.5 mAh g −1 ) with a capacity retention of 99.85% within the first 100 cycles in the voltage range between 1.4 and 5.0 V. [122] Flexible Cells: Future applications, such as wearable electronics, might require flexible batteries. Several flexible cells have been realized on polymer substrates, for example, polyimide, [148,262,263] and inorganic materials, such as thin and flexible YSZ sheets [264] and mica layers. [265] On polyimide substrates either amorphous cathodes, for example, MoO 3 or V 2 O 5 , or LFP annealed at 400 °C were employed.…”

This review discusses the contribution of physical vapor deposition (PVD) processes to the development of electrochemical energy storage systems with emphasis on solid‐state batteries. A brief overview of different PVD technologies and details highlighting the utility of PVD for the fabrication and characterization of individual battery materials are provided. In this context, the key methods that have been developed for the fabrication of solid electrolytes and active electrode materials with well‐defined properties are described, and demonstrations of how these techniques facilitate the in‐depth understanding of fundamental material properties and interfacial phenomena as well as the development of new materials are provided. Beyond the discussion of single components and interfaces, the progress on the device scale is also presented. State‐of‐the‐art solid‐state batteries, both academic and commercial types, are assessed in view of energy and power density as well as long‐term stability. Finally, recent efforts to improve the power and energy density through the development of 3D‐structured cells and the investigation of bulk cells are discussed.

“…Except for the chemical changes, in practice, if the TFLBs are exposed to repeated external load and mechanical fatigue, the contact loss is highly prone to occur at the current collector and electrode interfaces upon dynamic bending, also greatly affecting the bulk resistance. [250,251] Moreover, the adhesion between the films and substrate is another important issue that limits the durability of TFLBs, as demonstrated by the superior performance of TFLBs fabricated on Pt/Cr/ Al 2 O 3 compared to those on Pt/Al 2 O 3 substrates.

All-solid-state thin-film lithium batteries (TFLBs) are the ideal wireless power sources for on-chip micro/nanodevices due to the significant advantages of safety, portability, and integration. As the bottleneck for increasing the energy density of TFLBs, the key components of cathode, electrolyte, and anode are still underway to be improved. In this review, a brief history of TFLBs is first outlined by presenting several TFLB configurations. Based on the state-of-the-art materials developed for lithium-ion batteries (LIBs), the challenges and related strategies for the application of those potential electrode and electrolyte materials in TFLBs are discussed. Given the advanced manufacture and characterization techniques, the recent advances of TFLBs are reviewed for pursuing the high-energy-density and long-termdurability demands, which could guide the development of future TFLBs and analogous all-solid-state lithium batteries.

“…Solid polymer electrolytes (SPEs) are emerging as a promising solution to achieve broad electrochemical stability window, excellent mechanical properties, and good safety for developing high-performance all-solid-state batteries (ASSB) [ 1 , 2 , 3 , 4 ]. Due to the effects of the preparation process and electrochemical operation, many SPEs are usually in a non-equilibrium state, in which the free volume and microstructure would evolve with time [ 5 , 6 ].…”

The prediction of electrochemical performance is the basis for long-term service of all-solid-state-battery (ASSB) regarding the time-aging of solid polymer electrolytes. To get insight into the influence mechanism of electrolyte aging on cell fading, we have established a continuum model for quantitatively analyzing the capacity evolution of the lithium battery during the time-aging process. The simulations have unveiled the phenomenon of electrolyte-aging-induced capacity degradation. The effects of discharge rate, operating temperature, and lithium-salt concentration in the electrolyte, as well as the electrolyte thickness, have also been explored in detail. The results have shown that capacity loss of ASSB is controlled by the decrease in the contact area of the electrolyte/electrode interface at the initial aging stage and is subsequently dominated by the mobilities of lithium-ion across the aging electrolyte. Moreover, reducing the discharge rate or increasing the operating temperature can weaken this cell deterioration. Besides, the thinner electrolyte film with acceptable lithium salt content benefits the durability of the ASSB. It has also been found that the negative effect of the aging electrolytes can be relieved if the electrolyte conductivity is kept being above a critical value under the storage and using conditions.
