“…Also, the increase in initial discharge capacity is detected, which might be coming from the catalytic effect of Te on sulfur redox. [54][55][56][57] Thus, it is apparent that achieving a meaningful improvement in anodefree cell performance necessitates a minimum of 10 wt% of Te in the Li 2 S cathode.…”

“…Typically, nanoscale materials exhibit a substantially higher surface-area-to-volume ratio compared to their bulk counterparts, which results in shorter diffusion distances for electrons and Li ions within the nanoparticles. [57][58][59] In particular, nanowires are well known for their superior mechanical and thermal stability, as well as their excellent electrical conductivity. [60][61][62] It has been reported that the high-surface area nanowire structured material can be synthesized through the hydrothermal reaction.…”

Enhancing the reversibility of Li is crucial for extending the cycle life of Li‐limited anode‐free lithium–sulfur (Li–S) batteries. Incorporating tellurium (Te) in the system has proven to be highly effective by its reaction with polysulfides and forming a passivating interfacial layer on Li surface, which reduces the Li‐ion diffusion barrier. However, due to the poor utilization of Te, a significant amount of Te is required to improve cell cycling performance. To address this, nanowire‐structured Te (TeNW) is synthesized via a hydrothermal method and applied to Li2S‐based anode‐free cells to minimize the Te content in the system while extending the cell cycle life. Coating TeNW onto the separator greatly enhances Te utilization and demonstrates a significant cycle life improvement (38% retention over 300 cycles) with only 4 wt% TeNW content relative to the active material. The versatility of TeNW is further demonstrated by utilizing them with carbon nanotubes as the anode substrate. The exceptional performance of TeNW is attributed to the high‐surface‐area nanostructure and excellent conductive network, facilitating efficient electron transfer during cell cycling. These advantageous properties position TeNW as a promising material to enhance the cycle life of Li‐limited Li–S batteries.

Thanks to the significantly higher energy density compared with universal commercialized Li‐ion batteries, lithium–sulfur (Li–S) batteries are being investigated for use in prospective energy storage devices. However, the inadequate electrochemical kinetics of reactants and intermediates hinder commercial utilization. This limitation results in substantial capacity degradation and short battery lifespans, thereby impeding the battery's power export. Meanwhile, the capacity attenuation induced by the undesirable shuttle effect further hinders their industrialization. Considerable effort has been invested in developing electrocatalysts to fix lithium polysulfides and boost their conversion effectively. In the conventional process, the planar electrodes are prepared by slurry‐casting, which limits the electron and ion transfer paths, especially when the thickness of the electrodes is relatively large. Compared with traditional manufacturing methods, direct ink writing (DIW) technology offers unique advantages in both geometry shaping and rapid prototyping, and even complex three‐dimensional structures with high sulfur loading. Hence, this review presents a detailed description of the current developments in terms of Li–S batteries in DIW of metal‐based electrocatalysts. A thorough exploration of the behavior chemistry of electrocatalysis is provided, and the adhibition of metal‐based catalysts used for Li–S batteries is summarized from the aspect of material usage and performance enhancement. Then, the working principle of DIW technology and the requirements of used inks are presented, with a detailed focus on the latest advancements in DIW of metal‐based catalysts in Li–S battery systems. Their challenges and prospects are discussed to guide their future development.

“…The “holy grail” electrode for rechargeable high-energy-density batteries has long been thought to be lithium metal due to its extremely high theoretical specific capacity (3860 mA h g –1 ) and the lowest negative electrochemical potential (−3.040 V vs the conventional hydrogen electrode). , However, the issues such as dendrite growth, low Coulombic efficiency, and great volume change have been preventing Li metal anodes from playing a greater role in practical applications. The decisive step to achieve safe and effective operation of lithium metal anodes is to suppress lithium dendrite growth, which determines the fate of several promising energy storage system candidates in the next-generation energy storage system, including rechargeable Li air batteries, , Li sulfur batteries, − and Li ion batteries. − …”

Lithium metal anodes (LMAs) are considered one of the most promising anode materials for lithium metal batteries due to their high theoretical specific capacity (3860 mAh g −1 ) and low anode potential (−3.04 V compared to the standard hydrogen potential). However, the further application of lithium metal batteries is hindered by problems such as lithium dendrite growth and volume change of the anode. Fortunately, to address these issues in lithium metal batteries, various applications of nanomodification technologies have been proposed for lithium metal anodes, such as using nanomaterials and constructing nanostructures. These nanomodification technologies have standardized the plating/stripping behavior of lithium, significantly improving the electrochemical performance and lithium morphology of LMAs. This brief review systematically summarizes the latest research progress in LMA nanomodification technology to inhibit lithium dendrite growth. First, the problems of LMAs in practical applications are analyzed. Then, we summarize the forward-looking strategies and the latest research progress based on nanomaterials and nanostructures from the perspectives of current collectors, protection of the interface layer, separators, and all-solid-state lithium batteries. Finally, the future development of nanomodification technology for the protection of lithium metal batteries is summarized and prospected.
