“…In conclusion, first, the specific capacities of both HS and conventional LS are within a reasonable range of the specific capacities of LMO material (90-120 mAh˖g -1 ) [8,26], and the areal capacities and volumetric capacities of the LS are similar to those of LMO half-cells [27,28]. Also, as the electrode thickness increases, the areal capacities and volumetric capacities increase.…”

New hybrid 3D structure electrodes with a high aspect ratio are fabricated through extrusionbased additive manufacturing to achieve high mass loading. This new 3D printed battery exhibits both high areal and specific capacity, thus overcoming the trade-off between the two of the conventional laminated batteries. This excellent battery performance is achieved by introducing a hybrid 3D structure that utilizes the benefits of the existing laminated structure and threedimensional interdigitated structure. In addition, conventional battery paste components are used optimally to fit the 3D printing process, which eliminates the need for a complicated solvent preparation process required for a typical 3D printing process for battery applications. Using the CR2032 coin cell, the general assembly problem that occurs at the 3D structured electrodes is solved, which means that the proposed hybrid 3D structure can easily be added to the existing lamination structure. This innovative design and fabrication process demonstrates the high areal energy and power density, which is a critical requirement for energy storage systems in transportation and stationary applications.

“…In this configuration, the conductive metal‐based substrates serve as both efficient current collectors and architectural supporting matrixes to construct binder‐free cathodes. Until now, a wide variety of metals, including Al, [ 103 ] Au, [ 104,112 ] Pt, [ 62 ] Ni, [ 117 ] Cu, [ 116 ] Ti, [ 109,120 ] and stainless steel, [ 119 ] have been utilized as substrates to prepare various cathodes. For example, LiCoO 2 , the first successful commercial cathode material, was incorporated into portable electronic devices in 1980.…”

Commercial lithium‐ion batteries (LIBs), limited by their insufficient reversible capacity, short cyclability, and high cost, are facing ever‐growing requirements for further increases in power capability, energy density, lifespan, and flexibility. The presence of insulating and electrochemically inactive binders in commercial LIB electrodes causes uneven active material distribution and poor contact of these materials with substrates, reducing battery performance. Thus, nanostructured electrodes with binder‐free designs are developed and have numerous advantages including large surface area, robust adhesion to substrates, high areal/specific capacity, fast electron/ion transfer, and free space for alleviating volume expansion, leading to superior battery performance. Herein, recent progress on different kinds of supporting matrixes including metals, carbonaceous materials, and polymers as well as other substrates for binder‐free nanostructured electrodes in LIBs are summarized systematically. Furthermore, the potential applications of these binder‐free nanostructured electrodes in practical full‐cell‐configuration LIBs, in particular fully flexible/stretchable LIBs, are outlined in detail. Finally, the future opportunities and challenges for such full‐cell LIBs based on binder‐free nanostructured electrodes are discussed.

“…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.
