“…Most importantly, the Zn symmetric cells using ZCYSM@Zn film as anode antifluctuator achieve an ultrahigh CPC of 2.25 and 4 Ah cm −2 at the current density of 1 and 10 mA cm −2 , respectively, which has far exceeded the previously reported CPC value of Zn-based powder electrodes. [5,11,12,[14][15][16][17]30,32,33] To further study the mechanism of dendrite suppression by ZCYSM@Zn antifluctuator, the distribution of Zn 2+ concentration field, current density, and electric field in ZCYSM@Zn film are simulated by FEA. The electric field and the distribution of current density on the surface of the Zn-P film is notably inhomogeneous due to the low conductivity and large volume distort the current density and electric field direction of the surface protuberance sites, as presented in Figure 4a-c.…”

“…Lithium-ion batteries (LIBs) have attracted great attention in the market of portable electronic products and electric nucleation, and disjointed electronic transition. [12] Thus, uneven deposition is more likely to occur on the top region of Zn-P, and then the dendrites will accumulate continuously during Zn plating/stripping and eventually penetrate into the separator, causing internal short circuit and the generation of "dead zinc." [13] Besides, the volume shrinkage induced by Zn dissolution during the discharging stage depletes the electrical contact between powders.…”

Aqueous Zn ion batteries are promising systems due to their intrinsic safety, low cost, and non‐toxicity, and the Zn corrosion and dendrite growth will cause the poor reversibility of Zn anode. Herein, the porous Zn@C solid, hollow, and yolk–shell microsphere films are developed as Zn anode antifluctuator (ZAAF). The prepared yolk–shell microspheres (Zn@C yolk–shell microsphere [ZCYSM]) film with superior buffering can effectively restrict the deposition of Zn metal in its interior and inhibit the volume expansion during plating/stripping process, thus modulating the Zn2+ flux and enabling stable Zn cycling. As a proof of concept, the ZCYSM@Zn symmetric cells achieve the excellent cyclic stability over 4000 h and cumulative plated capacity of 4 Ah cm−2 at a high current density of 10 mA cm−2. Concomitantly, the suppressed corrosion reactions and dendrite‐free ZAAF significantly improve the durability of full cells (coupled to CaV6O16·3H2O). Additionally, durable pouch cell and electrochemical neuromorphic inorganic device (ENIDe) are integrated to simulate neural network, providing a strategy for extreme interconnectivity comparable to the human brain.

“…In contrast, the introduction of in situ curing technique is important for DIW and IJP to retain the printed structure. One innovative approach is the use of a 3D cold trap, as demonstrated by Lu et al By conducting the entire printing process in a low-temperature environment, the ink underwent instantaneous freezing, resulting in the elimination of ink flow and the preservation of the original structure. The induction of ice crystal formation further enhanced the directional alignment stability of materials such as MXene nanosheets during the freezing process.…”

In the era of rapidly evolving smart electronic devices, the development of power supplies with miniaturization and versatility is imperative. Prevailing manufacturing approaches for basic energy modules impose limitations on their size and shape design. Printing is an emerging technique to fabricate energy storage systems with tailorable mass loading and compelling energy output, benefiting from elaborate structural configurations and unobstructed charge transports. The derived “printable energy storage” realm is now focusing on materials exploration, ink formulation, and device construction. This contribution aims to illustrate the current state-of-the-art in printable energy storage and identify the existing challenges in the 3D printing design of electrodes. Insights into the future outlooks and directions for the development of this field are provided, with the goal of enabling printable energy storage toward practical applications.

“…On the one hand, the commonly used pure Zn anode is severely comminuted during the charge and discharge cycles due to its unstable electrode structure. [ 18–22 ] The electrical contact failures in this process, leading to low capacity and short cycle life of the battery. On the other hand, neutral ZABs exhibit low power density, and poor energy efficiency at high current density due to the slow reaction kinetics of anode.…”

Neutral zinc‐air batteries are considered potential wearable energy storage devices due to their high theoretical energy density, superior safety, and low cost. However, the current performance of neutral zinc‐air batteries is severely influenced by the zinc anodes. The pure zinc anode can be comminuted during charge and discharge cycles due to its unstable electrode structure, resulting in the failure of electrical contact. As a result, the battery exhibits low capacity and short cycle life. In addition, the pure zinc anodes show slow reaction kinetics in neutral electrolytes, which causes the battery to perform low power density and poor energy efficiency. Besides, pure zinc anodes own high bending stiffness, which cannot meet the demands for powering flexible electronics. Herein, a new kind of hybrid zinc/carbon nanotube fiber anode with a stable electrode structure, high reaction activity, as well as high flexibility is proposed to produce high‐performance neutral zinc‐air batteries. The fabricated fiber battery showed a high specific capacity and maximum power density of 645.3 mAh g−1 and 615.8 mW g−1, respectively. Furthermore, a high energy efficiency of 71% is achieved, the highest among the reported neutral zinc‐air batteries. The entire fiber battery is highly flexible, highlighting its potential for wearable energy storage applications.
