“…improving graphite for use in LMBs could involve engineering the surface properties of graphite, developing electrolytes that facilitate more uniform Li deposition, or using additives that can reduce Li dendrites' formation. [128][129][130] Recently, the idea of a hybrid anode combining graphite and Li metal was proposed, aiming at overcoming the limitations of graphite in LIBs. As schematically shown in Figure 5a, the limitations of graphite anode stem from its low theoretical capacity, which results in Li metal plating outside of the electrode when beyond the theoretical value.…”

Lithium metal batteries (LMBs) offer high energy density and promise as a future technology. Yet, their adoption is hindered by safety concerns and cycle life stability, arising from Li dendrite formation, solid electrolyte interphase instability, and volume changes during cycling. In response to these challenges, carbon‐based materials have been utilized as an artificial interface layer for modifying the surface of copper current collector in LMBs. Among the diverse carbon‐based materials, 0D carbon, with its high specific surface area, is advantageous for enhancing Li ion transport rates and ensuring uniform current distribution. 1D carbon structures foster a network that facilitates Li ion diffusion, while 2D carbon establishes a protective layer, mitigating side reactions. 3D carbon structures promote Li deposition within their internal cavities, effectively controlling volume fluctuations. With this understanding, this review delves into the latest advancements in carbon‐based materials for modifying copper current collectors. It offers a detailed exploration of how each dimension of carbon‐based materials contributes to regulating Li deposition. Furthermore, the ongoing challenges and potential avenues in the development of carbon‐modified copper current collectors for LMBs are spotlighted, aiming to provide insightful guidance for the design of anode‐free Li metal batteries.

Materials need to be engineered to make them device-ready. A mescoporous, a combination of meso-and microporous, nickel titanate−titanium oxide (m-NTTO) complex has been synthesized here using a simple sol−gel method for making a solid-state binder-free supercapacitor from the as-prepared powder. The m-NTTO sample, well characterized using electron microscopy, N 2 adsorption−desorption isotherm, X-ray diffraction, and Raman spectroscopy was tested for its energy storage capabilities. The supercapacitive performance of m-NTTO is investigated through cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and galvanostatic charge−discharge (GCD). It shows a dominant electric double-layer capacitance with a total specific capacitance of 195 F/g at 10 mV/s and fast charging and slow discharging. Additionally, it exhibits high specific capacitance, excellent cyclic stability, and high retention. Using this sample, a prototype solid-state symmetric supercapacitor device has been fabricated to demonstrate excellent electrochemical performance with high specific capacitance, energy density, and power density was obtained, which suggests that the m-NTTO is suitable candidate material for energy storage application.
