“…The motivation for developing three-dimensional batteries is much greater today than even a decade ago. [42] Just "googling" of the term "3D microbatteries" provides 103,000 results in 0.37 seconds. Beyond question is the essential role of 3DMBs in the new generation of small, wearable and portable devices with high autonomy, flexibility, light weight, safety and environmental friendliness.…”

“…All this, complicated by different 3D designs, makes the direct comparison of the experimental data practically impossible (see Tables 2 and 3). [12] Very informative reviews on 3D microbatteries, in which the major issues mentioned above are discussed, were published by Roberts et al, [41] Hur et al, [6] Zheng et al, [7] Moitzheim et al, [12] Long et al [42] and Ni et al [43] In order to avoid repetitions, we just provide here a brief summary. Thus, the major active cathode and anode materials actually do not much differ from the materials used in conventional batteries.…”

The miniaturization of implantable medical devices, remote microsensors and transmitters, “smart” cards, and Internet of Things (IoT) systems is impeded by the absence of high‐performance micro‐size power sources. Insufficient areal energy density from thin‐film planar microbatteries has inspired a search for three‐dimensional microbatteries (3DMB) with the use of low‐cost and efficient micro‐ and nano‐scale materials and techniques. In our short review, we present our outlook on the state‐of‐the‐art development of advanced 3D‐microbattery designs and methods of the fabrication of electrode materials. Special attention is given to the 3D‐printing approach, which holds many opportunities for the mass production of microbatteries and their direct integration with electronic devices.

“…Indeed, thanks to such cutting-edge technology, it is now possible to imagine the development of LIB threedimensional (3D) architectures reported to increase the electroactive surface area greatly, allowing the Li + diffusion towards two or three dimensions and thus improving the final electrochemical performance of the battery in terms of specific capacity and power (Trembacki et al, 2019;Maurel et al, 2020b); on the other hand, conventional 2D LIB architectures of the positive electrode, separators, negative electrode, and current collector are stacked or rolled (parallel plates configuration), previously reported to allow only Li + diffusion in 1D. While 3D LIB structures, originally proposed by Long et al (Long et al, 2004;Long et al, 2020), were extensively developed independently through traditional techniques such as electrodeposition, the assembly of both electrodes manually was reported to be particularly complex due to the irregular electrode surfaces causing short circuits (Taberna et al, 2006). As an innovative alternative and to prevent this last issue, AM appears as a unique route to obtain such complex interlaced electrode architectures.…”

Ag-Coated Cu/Polylactic Acid Composite Filament for Lithium and Sodium-Ion Battery Current Collector Three-Dimensional Printing via Thermoplastic Material Extrusion

et al. 2021

This article focuses on the development of polylactic acid– (PLA-) based thermoplastic composite filament for its use, once 3D printed via thermoplastic material extrusion (TME), as current collector at the negative electrode side of a lithium-ion battery or sodium-ion battery. High electronic conductivity is achieved through the introduction of Ag-coated Cu charges, while appropriate mechanical performance to allow printability was maintained through the incorporation of poly(ethylene glycol) dimethyl ether average Mn ∼ 500 (PEGDME500) as a plasticizer into the PLA polymer matrix. Herein, thermal, electrical, morphological, electrochemical, and printability characteristics are discussed thoroughly. While Ag-Li alloy formation is reported at 0.1V upon cycling, its use with active materials such as Li4Ti5O12 (LTO) or Li2-terephthalate (Li2TP) operating at a plateau at higher potential is demonstrated. Furthermore, its ability to be used with negative electrode active material of sodium-ion battery technology in a wide potential window is demonstrated.

Fiber-shaped supercapacitors (FSSCs) are the most state-of-the-art power supplies suitable for wearable devices, but the intrinsically limited cylindrical space of fibers restricts their high electrochemical performance, which must be overcome with a delicate and systematic architectural process. Here, a simple but effective 3D architectural strategy for fabricating FSSCs with high performance and flexibility is proposed. Highly conductive liquid crystal spun carbon nanotube fiber (CNTF) is an excellent 1D core fiber for the electrophoretic deposition of graphene oxide (GO). The deposited GO forms a vertical 3D structure on the CNTF (VG@CNTF), which can be successfully preserved by a consecutive coating of pseudocapacitive active materials onto the surface of VG. Notably, a solid-state asymmetric FSSC shows an outstanding performance of 65 Wh kg −1 at 100 kW kg −1 and exceptional stability and flexibility (capacitance retention of 98.60% at bending angles of 90° and 93.1% after 5000 bending cycles). This work can provide new insight into the development of high-performance FSSCs for practical wearable applications.
