Abstract Porous metal current collectors (CCs) serve as key component for aqueous Zn‐ion batteries (AZIBs). Herein, a lightweight 3D‐Cu architecture with customizable geometries is developed to enable reversible Zn‐metal cycling. The prepared by 3D‐printing crosslink‐able polymer scaffold followed Cu‐metallization. printed optimized endow electric conductivity that on‐par commercial Cu foam, but can reduce ≈80% of the weight and consumption Cu. A Zn‐philic graphene (Gr) coating adopted...
Abstract The interrelation is explored between external pressure (0.1, 1, and 10 MPa), solid electrolyte interphase (SEI) structure/morphology, lithium metal plating/stripping behavior. To simulate anode‐free batteries (AF‐LMBs) analysis performed on “empty” Cu current collectors in standard carbonate electrolyte. Lower promotes organic‐rich SEI macroscopically heterogeneous, filament‐like Li electrodeposits interspersed with pores. Higher inorganic F‐rich more uniform denser film. A...
High Li-storage-capacity particles such as alloying-based anodes (Si, Sn, Ge, etc.) are core components for next-generation Li-ion batteries (LIBs) but crippled by their intrinsic volume expansion issues. While pore pre-plantation represents a mainstream solution, seldom do this strategy fully satisfy the requirements in practical LIBs. One prominent issue is that porous reduce electrode density and negate volumetric performance (Wh L
Lithium Metal Battery An ancient wizard is hammering sharp crystals of lithium metal placed on a ceremonial anvil perfect hexagons. The pressure so high that lightning generated. In article number 2302261, Wei Liu, David Mitlin, and co-workers demonstrated the opposite: By covering copper current collector by defect-free graphene external for planar Li electrodeposition reduced an order magnitude.
