“…83 Such architecture not only resulted in the increase of capacity by 2.5 times (1 mA h cm À2 at C/2) compared to the 2D structure but also showed good performance under the mechanical strain and very small capacity fading over 100 cycles. 83 Thus, this microbattery proved to be a promising approach with a further target to increase the energy density by varying the electrode materials and improving the micropillars' density. Other interesting LIBs structures with PEO-based electrolytes have also been tested in coin cells.…”

“…The electrode (PBA-5) exhibited reversible gravimetric capacity of ≈110 mAh g −1 (at 0.1 mA cm −2 ), consistent with previous reports with the iron hexacyanoferrate based materials [31,33,34] and a huge areal capacity of ≈650 µAh cm −2 (≈5.41 µAh cm −2 µm −1 ) as compared to other cathodic materials for microbattery applications. [17,[35][36][37][38][39][40][41][42] Indeed, the size and the compactness being the primary selection criteria, it is imperative to consider all reported properties normalized to the footprint area on the chip. The different porous Li-Fe-PBA electrodes show good rate stability with excellent capacity retention upon reverting to slower rates (Figure S4, Supporting Information).…”

Small dimension Li‐ion microbatteries are of great interest for embedded microsystems and on‐chip electronics. However, the deposition of fully crystallized cathode thin film generally requires high temperature synthesis or annealing, incompatible with microfabrication processes of integrated Si devices. In this work, a low temperature deposition process of a porous Prussian blue‐based cathode on Si wafers is reported. The active material is electrodeposited under aqueous conditions using a pulsed deposition protocol on a porous dendritic metallic current collector that ensures good electronic conductivity of the composite. The high voltage cathodes exhibit a huge areal capacity of ≈650 μAh cm−2 and are able to withstand more than 2000 cycles at 0.25 mA cm−2 rate. The application of these electrode composites with porous Sn based alloying anodes is also demonstrated for the first time in full cell configuration, with high areal energy of 3.1 J cm−2 and more than 95% reversible capacity. This outstanding performance can be attributed to uniform deposition of Prussian blue materials on conductive matrix, which maintains electronic conductivity while simultaneously providing mechanical integrity to the electrode. This finding opens new horizons in the monolithic integration of energy storage components compatible with the semiconductor industry for self‐powered microsystems.

Highly stretchable and cycle‐stable (high operando dynamic stretchable) zinc‐ion microbatteries that are nonharmful, environmentally friendly, and low cost are developed herein for the first time. Stretchable zinc‐ion microbatteries (SZIMBs) are fabricated by simultaneously incorporating the facile synthesis of conducting polymer‐intercalated vanadium oxide nanofibers as flexible and elastic cathode materials; the construction, design, and assembly of wavy‐type microdevices; and pre‐zincation techniques that break stereotypes. The poly(3,4‐ethylene dioxythiophene) (PEDOT)‐intercalated zinc vanadium oxide nanofiber zinc‐ion microbatteries (E‐ZVONF‐SZIMBs) manufactured by combining these strategies exhibit a maximum specific capacity of 0.16 mAh cm−2, high energy density of 0.112 mWh cm−2, and high power density of 3.5 mW cm−2 and maintain 83.7% of the initial specific capacity after 500 cycles. The E‐ZVONF‐SZIMBs maintain 78.9% of their initial specific capacity even after 7000 mechanical stretching/bending tests, exhibiting excellent operando dynamic stretchability. The stretchable zinc‐ion microbatteries show practical feasibility by maintaining 80% and 90% of the capacity at −20 and 60°C under 200% strain, respectively. These remarkable achievements in the field of stretchable zinc‐ion microbatteries are expected to have significant implications for the development of future device platforms.
