water electrolyzers performed in acidic media, such as lower cost cell components, which has led to their commercialization at the megawatt level. [1] In addition, performing electrolysis under alkaline conditions can improve the purity of the generated hydrogen gas, [2] and, importantly, the less corrosive environment allows the use of most nonplatinum group metal catalysts for the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER). [3] However, commercial AWS electrolyzers operate at relatively low current densities (<400 mA cm −2) and voltage efficiencies (<80%), [4] compared to PEM electrolyzers. Therefore, increasing the operational current density and voltage

Lithium‐metal batteries (LMBs) are regarded as one of the best choices for next‐generation energy storage devices. However, the low Coulombic efficiency, lithium dendrite growth, and volume expansion of lithium‐metal anodes are dragging LMBs out of successful commercialization. Herein, the application of various porous materials in LMBs is focused on. First, several representative works are summarized to highlight the recent key progress of porous materials in LMBs, categorized into current collectors, thin 3D “hosts,” protection layers, and separators. Then, the existing challenges are discussed and future research needs to present more thorough characterizations of porous materials are advocated for, such as their porosity, electric conductivity, specific surface area, and mass density, to elaborate on their positive influence on electrochemical performance. Finally, future strategies with porous materials to build long‐cycle‐life, high‐energy‐density lithium‐metal full cells toward realistic performance targets are envisioned.

“…Lim et al developed a low‐cost, simple method to construct a firm Cu porous framework by extrusion 3D‐printing (Figure 8(D)). 93 The 3D‐printed Cu framework (3DP‐Cu) can hold constructed microchannels between filaments even over supernal compressive pressure of 1.4 MPa, which would effectively restrain Li dendrite growth and alleviate volume changes. The cell with 3DP‐Cu based Li anode reaches an exceptional areal capacity of 20 mA h cm −2 with over 1 mA cm −2 , and steady Li plating/stripping behavior even at a high current density of 10 mA cm −2 .…”

Lithium metal batteries (LMBs) are considered the most promising energy storage devices for applications such as electrical vehicles owing to its tremendous theoretical capacity (3860 mAh g−1). However, the serious safety issues and poor cycling performance caused by the dendritic crystal growth during deposition are concerned for any rechargeable batteries with a lithium metal anode. To make widespread adoption a possibility, considerable efforts have been devoted to suppressing lithium (Li) dendrite growth. In this review, the recent strategies to developing dendrite free Li anode, including constructing an artificial solid electrolyte interface, current collector modification, separator film improvement, and electrolyte additive, are summarized. The merits and shortcomings for different strategies are reviewed and a general summary and perspective on the next generation rechargeable batteries are presented.

Robust pure copper framework by extrusion 3D printing for advanced lithium metal anodes

Abstract: A novel robust and self-standing 3D-printed pure copper framework (3DP-Cu) is developed as a Li host and current collector. 3D-printing allows microchannels to be deliberately incorporated, benefiting both mechanical and electrochemical performances.
