The XRD diagram of the as-deposited LiNi 0.8 Co 0.2 O 2 thin film prepared by RSDT is shown in Fig. 1.The diagram is in good agreement with α-NaFeO 2 type that has a layered structure and space group of R3 m [25], [26].Although excess amount of lithium precursor is added to compensate for the loss of lithium in the flame, …
SnO x electrode thin films for lithium ion batteries were deposited by reactive and non-reactive rf magnetron sputtering of a SnO 2 target in an argon–oxygen atmosphere. Amorphous and nano-crystalline SnO x films could be synthesized, with regard to the O 2:Ar volume ratio in the sputter gas which was adjusted to 0, 3.5 or 10%.Laser …
All-solid-state thin film lithium micro-batteries have attracted more and more interests due to their potential applications as power sources for microelectronic devices. Thin film Li electrolyte, as the key part in the thin film batteries, is very important to the performance of the thin film batteries. This paper reviews a wide range of lithium …

Epitaxial vertically aligned nanocomposite (VAN) thin films have recently emerged in the Li-ion battery field. [16-18] They have the potential to overcome the aforementioned diffusivity limitations and could be used in micro-battery technologies. VANs consist of two interdigitated epitaxial oxides, with a highly ordered vertically aligned ...
The online version contains supplementary material available at 10.1007/s40820-023-01064-y.Lithium-sulfur (Li–S) system coupled with thin-film solid electrolyte as a novel high-energy micro-battery has enormous potential for …
Here, we have shown such a millimeter scale (2.5 × 1.7 mm) micro (236 μg) lithium-ion-based thin-film battery with flexibility (bending radius down to 1 cm) and biocompatibility.
The Si thin films with different thicknesses were tested as anode materials for lithium ion micro-batteries in this work. Although the Si thin films over 1 μm thick showed good cyclic performance without abrupt capacity fade up to the 70th cycle, the pulverization of the electrode during cycling unfortunately could not be avoided. However, …

All-solid-state thin-film lithium/lithium-ion microbatteries (TFBs) combining solid-state battery architecture and thin-film manufacturing are regarded as …
3D electrode design is proposed as an attractive approach to simultaneously increasing energy and power densities for all-solid-state thin film lithium microbatteries (TFBs). However, currently reported TFBs based on 3D electrodes prepared by atomic layer deposition or physical vapor deposition suffer from relatively low areal …
Free-standing thin film electrodes hold huge promise for solid-state and micro batteries required by a range of portable electronic devices. However, for lithium-sulfur (Li–S) and lithium-metal polysulfide (Li-MS x; M = Mo, V, Ti, etc.) batteries, the promising thin film electrodes are not possible yet because of low melting point of sulfur. …
In 1993, J. B. Bates et al. first discussed the performance and possibility of a thin-film battery assembled using a LiPON electrolyte film and Li anode [22]. Subsequently, thin-film batteries with LiPON films were intensively investigated, leading to the fabrication of a commercial-level micro battery.
Micro energy sources as the nucleus of intelligent microdevices guarantee their full autonomy in the dimensions of time and space. However, the state-of-the-art micro energy storage components, like all-solid-state thin-film microbatteries (ASSTFBs), whose direct integration is impeded by the stereotyped vacuum-based manufacturing …
