“…The Ag–Li alloying process begins below 0.1 V during the lithiation process after the SEI formation. The Li deposition curves shown in Figure b exhibit three platforms above 1.0 V on the Ag- and AgLN-coated Li unlike bare Cu- and LN-coated Cu, which could indicate the formation of alloy phases of Li x Ag above 0 V vs Li/Li + , as suggested by Jiang et al This alloying behavior was also observed in other reports. – In contrast, AgLN-coated Cu demonstrated a lithiation plateau clearer than that of Ag-coated Cu. Furthermore, the Li metal deposition potential of the Ag-coated Cu did not show a dip but only a sharp right-angle turn at the onset, as indicated by the red dashed arrow (Figure b).…”

“…However, the possibility of using a Cu-free thick Li metal anode is low . When the current collector is removed, random Li cracks occur owing to the resulting nonuniform current distribution and the cycle performance deteriorates. , Consequently, the use of thin Li metal (20 μm) on Cu foil is a step toward achieving high-power and high-density Li metal secondary batteries.…”

In this study, a stable solid electrolyte interface (SEI) and a Ag–Li alloy were formed through a simple slurry coating of silver (Ag) nanoparticles and Li nitrate (LiNO3) on a Li metal surface (AgLN-coated Li). The Ag–Li alloy has a high Li diffusion coefficient, which allowed the inward transfer of Li atoms, thus allowing Li to be deposited below the alloy. Moreover, the highly conductive SEI enabled the fast diffusion of Li ions corresponding to the alloy. This inward transfer resulted in dendrite suppression and improved the Coulombic efficiency (CE). The AgLN-coated Li exhibited an initial capacity retention >81% and CE > 99.7 ± 0.2% over 500 cycles at a discharge capacity of 2.3 mA h cm–2.

“…More importantly, the removal of the current collector for the Li anode may shorten the cell cycle life due to the formation of isolated Li cracks caused by the uneven stripping process of Li. 20 Without a current collector to anchor the isolated Li cracks, the cycling of Li metal, especially at a high rate or during high-capacity stripping, could be significantly shortened. 21…”

Lithium (Li)-metal batteries have regained broad interest in the battery research community. Although many studies on Li anode have been published in recent years, it is difficult to evaluate and compare these advances for practical applications. A key challenge is a gap between materials and component properties and the achievable large-format cell-level performance. In this paper, we investigate the critical experimental parameters that determine the cycle number of coin cells to understand the performance variations reported in the literature. To define the range of cell parameters, we exemplify a representative Li-metal pouch cell with specific energy of 300 Wh/kg to provide an effective validation of electrode materials and accurate cell performance evaluations. Based on the pouch-cell-level requirements, we propose a set of coin-cell parameters and testing conditions to expedite the discovery of new materials and their full integration into realistic battery systems.

“…Apart from the integrations mentioned above, MESD systems integrated with chemical-biomedical-physical sensors and executors have also aroused extensive interest in recent years. Xiao's group reported the fundamental issues involved in designing structural MBs and then demonstrated a functional acoustic transmitter driven by a tubular microbattery [215]. To evaluate the practical performance, a tubular microbattery, with a diameter of 4.8 mm, was put into an acoustic underwater transmitter, where the electronic elements were all tucked inside the tube (figure 14(e)).…”

The rapid progress of micro/nanoelectronic systems and miniaturized portable devices has tremendously increased the urgent demands for miniaturized and integrated power supplies. Miniaturized energy storage devices (MESDs), with their excellent properties and additional intelligent functions, are considered to be the preferable energy supplies for uninterrupted powering of microsystems. In this review, we aim to provide a comprehensive overview of the background, fundamentals, device configurations, manufacturing processes, and typical applications of MESDs, including their recent advances. Particular attention is paid to advanced device configurations, such as two-dimensional (2D) stacked, 2D planar interdigital, 2D arbitrary-shaped, three-dimensional planar, and wire-shaped structures, and their corresponding manufacturing strategies, such as printing, scribing, and masking techniques. Additionally, recent developments in MESDs, including microbatteries and microsupercapacitors, as well as microhybrid metal ion capacitors, are systematically summarized. A series of on-chip microsystems, created by integrating functional MESDs, are also highlighted. Finally, the remaining challenges and future research scope on MESDs are discussed.
