Abstract ：
Along with the constantly evolving functional microsystems toward more diversification, the more rigorous design deliberation of pursuing higher mass-loading of electrode materials and low-temperature fabrication compatibility have imposed unprecedented demand on integrable all-solid-state thin-film microbatteries. While the classic thin-film intercalation cathode prepared by vacuum-based techniques inevitably encountered a post-annealing process, tape-casting technologies hold great merits both in terms of high-mass loading and low-temperature processing. In this work, a novel microbattery configuration is developed by the combination of traditional tape-casting thick electrodes and sputtered inorganic thin-film solid electrolytes (similar to 3 mu m lithium phosphorus oxynitride). Enabled by physically pressed or vapor-deposited Li as an anode, solid-state batteries with tape-casted LiFePO4 electrodes exhibit outstanding cyclability and stability. To meet integration requirements, LiFePO4/LiPON/Si microbatteries were successfully fabricated at low temperatures and found to achieve a wide operating temperature range. This novel configuration has good prospects in promoting the thin-film microbattery enabling a paradigm shift and satisfying diversified requirements.

Abstract ：
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 technologies, for which an inevitable high-temperature annealing step (> 500 degrees C) can exert catastrophic effects on the attached microdevices during the crystallization of manufactured insertion thin-film cathodes, especially in flexible integration. Herein, a prototype construction is created to benchmark concrete feasibility for the low-temperature manufacturing of ASSTFBs via a nonvacuum-based spin-coating electrode architecture. Results show that the spin-coated LiFePO4 films enable low-temperature (approximate to 45 degrees C) manufacturing of ASSTFBs, by which it can deliver excellent cycling performance up to 1000 cycles. Importantly, this technology presents the versatility of integrating various cathode composites into ASSTFBs and is therefore generalized to the LiCoO2- and Li4Ti5O12-based solid-state chemistries. Furthermore, ASSTFBs with such compliant electrodes manifest outstanding flexibility without pronounced capacity degradation by successfully integrating on flexible temperature-sensitive substrates. The spin-coating protocol provides a general solution for excessive processing temperatures and ample opportunities for the development of on-chip integratable and flexible ASSTFBs.

Abstract ：
The application of 3D printing technology in fabricating quasi-solid-state micro-supercapacitors (MSCs) offers inherent benefits in programmable structural design and high-mass-loading electrode fabrication. Nevertheless, the absence of high-performance printable inks and the sluggish ion transport within thick electrodes present significant challenges to their practical charge storage capabilities. Here, a new NiCo2S4-based nanocomposite ink with excellent rheological properties has been successfully developed and the 3D structure of quasi-solid-state MSCs is rationally engineered through the direct-ink-writing 3D printing technology. Beneficial from the firmly anchored NiCo2S4 nanoparticles on the reduced graphene oxide (rGO) and the ordered 3D micropores, the thick electrodes with serrated architectures provide abundant reaction sites and exhibit enhanced ion transport. Consequently, the MSCs with triple-layer-serrated electrodes can deliver a high areal capacitance up to 416.7 mF cm(-2). In comparison to the latticed counterparts, the areal capacitances of serrated MSCs with single-, double-, and triple-layer electrodes are amplified by 127.1%, 349.8%, and 585.9%, respectively (under 1 mA cm(-2)). This study offers novel insights into the cross-scale design of materials and electrode architectures for quasi-solid-state MSCs with high areal capacitance, promoting their integration into flexible and portable electronic devices.

Abstract ：
Metal-organic frameworks (MOFs) have emerged as the versatile stage to synthesize carbonaceous materials with unique properties such as large surface area, tunable pore size, and controllable composition. The carbonaceous materials derived from MOFs maintain their excellent structural advantages and enable in situ doping with heteroatoms through a simple process. Numerous effects have been devoted to develop MOF-derived graphitic carbon and heteroatom-doped carbonaceous materials for energy conversion and storage. Herein, we review the nearest progresses of the fabrication, characterization, and application of MOF-derived graphitic carbon with different dimensions. Furthermore, we focus on MOF-derived heteroatom-doped carbon materials and their applications. Finally, we provide a summary and outlook on their future development. © 2024 Elsevier Inc.

Abstract ：
Beyond the high theoretical capacity, conversion-alloying metal chalcogenides (CAMCs) exhibit exceptional high-rate performance as Li-ion battery electrodes. However, the inherent origin of the high-rate performance remains elusive, especially given the lower intrinsic conductivity of CAMCs. Here, the correlation between phase evolution and charge transport dynamics in fully activated CAMCs is systematically investigated, elucidating a current-adaptive Li-ion storage mechanism to explain the anomalous high-rate performance. Briefly, the deconversion reaction manipulated by ion diffusion acts as a “regulator” to adaptively modulate the transition from metal (high electronic conductivity) and lithium chalcogenides (high ionic conductivity) to CAMCs, thus removing the charge transport bottleneck without affecting the formation of the metal feedstock required for the alloying reaction. On this basis, the high capacity can be maintained at high rates through a “fading-free” alloying reaction. This study offers a novel perspective for the design of high-rate electrode materials. © 2024 Wiley-VCH GmbH.

Abstract ：
Constructing a three-dimensional (3D) skeleton with a sodiophilic-modified layer (SML) has been proven to be an effective strategy to alleviate excessive volumetric deformation and continuous dendrite growth for sodium (Na) metal anodes. However, the weak binding force and violent reaction between the SML and the 3D skeleton lead to numerous cracks/defects and even pulverization of the SML during repeated Na plating/stripping. Herein, a lithiation pathway is presented to construct a sodiophilic Li-Sn alloy layer onto a 3D copper mesh to strengthen the SML for stable Na metal anodes. The lithiation 3D skeleton exhibits superior sodiophilicity, higher charge-transfer efficiency, and lower ion-diffusion barrier, contributing to the homogenization of ion-electronic flux and Na deposition. Simultaneously, the dense Li-Sn alloy is more stable than the monometal Sn-layer, which effectively prevents damage to the SML and enhances the stability of the SML. As a result, the asymmetrical cell exhibits great performance with a negligible nucleation overpotential and a high average Coulombic efficiency of 99.4%. Moreover, the full cell assembled with Na3V2(PO4)3 cathode delivers superior capacity retention of 91.3% after 1000 cycles at a current of 3C. © 2024 American Chemical Society.

Abstract ：
Two-dimensional (2D) metal oxides (2DMOs), such as MoO2, have made impressive strides in recent years, and their applicability in a number of fields such as electronic devices, optoelectronic devices and lasers has been demonstrated. However, 2DMOs present challenges in their synthesis using conventional methods due to their non-van der Waals nature. We report that KCl acts as a flux to prepare large-area 2DMOs with sub-millimeter scale. We systematically investigate the effects of temperature, homogeneous time and cooling rate on the products in the flux method, demonstrating that in this reaction a saturated homogenous solution is obtained upon the melting of the salt and precursor. Afterward, the cooling rate was adjusted to regulate the thickness of the target crystals, leading to the precipitation of 2D non-layered material from the supersaturated solution; by applying this method, the highly crystalline non-layered 2D MoO2 flakes with so far the largest lateral size of up to sub-millimeter scale (~ 464 μm) were yielded. Electrical studies have revealed that the 2D MoO2 features metallic properties, with an excellent sheet resistance as low as 99 Ω·square−1 at room temperature, and exhibits a property of charge density wave in the measurement of resistivity as a function of temperature.
