“…A high specific capacity of ∼120 mAh·g −1 and cycleability with a capacity retention >81% at the 4C rate after 90 cycles was attributed to the Mn-deficient structure. A multi-layer PLD process was utilized to deposit LMO films (90 nm thick) on Si-based substrates coated with Pt as the current collector [164]. A reversible capacity of 2.6 µAh·cm −2 (corresponding to a specific capacity of ≈28 µAh·cm −2 ·µm −1 or 66 mAh·g −1 assuming a dense film with 4.3 g·cm −3 ) was reached at an extremely high current density of 1889 µA·cm −2 (equivalent to the 348C rate) with a capacity retention of 86% over 3500 cycles.…”

This review article presents a survey of the literature on pulsed laser deposited thin film materials used in devices for energy storage and conversion, i.e., lithium microbatteries, supercapacitors, and electrochromic displays. Three classes of materials are considered: Positive electrode materials (cathodes), solid electrolytes, and negative electrode materials (anodes). The growth conditions and electrochemical properties are presented for each material and state-of-the-art of lithium microbatteries are also reported.

“…Highly stabilized capacitive performance has been encountered with a high retention capacity of 97.3% after 2000 cycles for sample S1. This galvanostatically calculated capacitance using discharge time could possibly be one of the very few reports and suggests the material to be promising cathode for asymmetric supercapacitor [18,[41][42][43]. For sample S2 and S3, 86% and 81% of capacity retention is observed, respectively ( fig.…”

Precise control of morphology of ultrafine LiMn₂O₄ nanorods as a supercapacitor electrode via a two-step hydrothermal method

We report three different synthesis routes while maintaining similar reaction conditions to choose an effective way to precisely control the growth of ultrafine one-dimensional (1D) LiMn 2 O 4 in the form of nanorods. We developed a novel method of mixing the precursors through hydrothermal, yielding low dimensional precursors for effective solid state reaction to synthesize the nanorods. However, to achieve these, highly uniform β-MnO 2 nanorods were initially grown as one of the main precursors. The uniformity observed in as grown β-MnO 2 nanorods using hydrothermal technique help to attract minute LiOH particles upon mixing over its highly confined nano-regime surface. This facilitated the solid state reaction between MnO 2 and LiOH to develop one of the finest LiMn 2 O 4 nanorods with diameters of 10-80 nm possessing high surface area of 88.294 m 2 /g. We find superior charge storage behaviour for these finely ordered 1D nanostructures as supercapacitor electrodes in KOH with K 3 Fe(CN) 6 as electrolyte in contrast to Li 2 SO 4 . A high pseudo-capacitance of 653.5 F/g at 15 A/g is observed using galvanostatic discharge time with high retention capacity of 93% after 4000 cycles. The enhanced charge storage property may arise from the redox couple [Fe(CN) 6 ] 3− /[Fe(CN) 6 ] 4− and K + ions of the electrolyte. To the best of our knowledge, we demonstrate for the first time the effectiveness of a two-step hydrothermal method in tuning the supercapacitive behaviour of 1D LiMn 2 O 4 in redox additive electrolyte.

“…Later, Yao et al designed an ultrathin microbattery-pressure sensor integrated system based on a flexible aqueous rechargeable Zn-MnO 2 microbattery for energy storage. [18] Up to now, there are many types of microbatteries have been reported, like Li-ion microbattery, [5] Zn-ion microbattery [19] and so on, are one of the most common types of microbatteries. The various novel strategy micromatteries have become an important research fields, like dual-metal-ion battery, [20] but the miniaturization of dual-ion batteries has not been developed yet.…”

Humans live today in a high‐tech and informationalized society. With the development of the emerging electronic information age, various electronic systems are inclined to be multifunctional and miniaturized. It is urgent to develop “small and powerful” micro‐batteries with flexibility and high electrochemical performance to meet the diverse needs of microelectronic components. However, low electrochemical performance exists in traditional microenergy storage devices, which fail to satisfy the energy needs for microdevices. Here, for the first time, a planar integrated flexible rechargeable dual‐ion microbattery (DIMB) is reported, which is fabricated from an interdigital pattern of graphite as an electrode and lithium hexafluorophosphate as an electrolyte. As a microbattery, the DIMB exhibits a high reversible capacity of 56.50 mAh cm−3, and excellent cycle stability with 90% capacity retention after 300 cycles under a high working voltage. The application of DIMB in microdevices, such as light‐emitting diodes (LEDs), digital electronic game consoles, and electrochromic glasses is also investigated, fully demonstrating its “small and powerful” performance. The integrated DIMB is a high‐voltage microdevice that reaches a nonpareil discharge voltage of about 100 V and a charging capacity of 102 mAh g−1. This dual ion‐based flexible microbattery could become a promising candidate for energy storage and conversion components in next‐generation microelectronic devices and integrated electronic devices.
