Li(110) lattice plane evolution induced by a 3D MXene skeleton for stable lithium metal anodes

Abstract

Non-uniform plating-stripping behaviours of Li metal anodes hinder the application of Li-based batteries with high energy density. Here, a stable 3D matrix is designed by coating carbon skeleton with MXene,...

Directing (110) Oriented Lithium Deposition through High‐flux Solid Electrolyte Interphase for Dendrite‐free Lithium Metal Batteries

“…Finally, the Li (110) plane obscures the fast‐growing Li (200) plane and retain at the final Li plating process with dendrite‐free planar morphology parallel to the substrate. Besides, the forming Li (110) plane shows the lower Li atoms migration energy barrier of 0.02 eV than that of 0.12 eV for Li (200) (Supplementary Figure S1c), which in turn benefits fast Li atoms transport on the Li surface, resulting in small deposition overpotential, avoiding Li atoms tip aggregation, and inducing planar deposition [8,11] . Based on the above discussion, it is promising to regulate the crystal orientation of Li deposition through SEI engineering.…”

“…Previously, due to the high reactivity of Li and the complexity of LMBs system, it is difficult to efficiently adjust Li electro‐crystallization [6] . (110) orientated Li deposition could only be achieved in a few reported works at a high Li electrodeposition capacity (more than 10 mAh cm −2 ) [7] or epitaxial electrodeposition at the specific skeletons such as 3D MXene [8] . However, the practical application of those strategies confronts an open question when considering the low negative/positive electrode capacity ratio (N/P), the cost of energy density, and the requirement of low engineering and technical difficulties.…”

3D Flexible Electrospun Nanocomposite Polymer Electrolyte Based on Li1.45Al0.45Ge0.2Ti1.35(PO4)3 for Lithium Metal Batteries

“…Rechargeable lithium-ion batteries have attained importance in day-to-day applications from portable electronic devices to electric vehicles. , However, conventional lithium-ion batteries with organic liquid electrolytes need an update from ignitability and liquid leakage as they can catch fire at high temperatures and can accidentally cause short circuit. − To overcome these challenges, the development of solid-state lithium batteries (SSLBs) is recognized as one of the superior approaches. SSLBs have several advantages, including the evasion of shortcomings associated with liquid leakage, vaporization, and flammability. , Moreover, in addition to enhanced safety, many solid electrolytes have a broad electrochemical potential window, which allows for the application of high-voltage electrode materials in solid-state lithium batteries, resulting in high energy density. − …”

Three-dimensional flower-like NiO on Cu foam as a lithiophilic current collector for high-performance lithium metal batteries

“…[9][10][11] However, there are some problems that restrict the development of lithium metal anodes. [12][13][14][15] On the one hand, lithium dendrites produced by uneven deposition of lithium make it difficult to produce stable SEI lms, and the existence of dead lithium leads to a decrease in the lithium utilization ratio, thus leading to rapid capacity deterioration and high safety hazards. 16,17 On the other hand, the repeated breakage of lithium dendrites and formation of an SEI layer also consume lithium metal, which leads to a decrease in coulombic efficiency and the shortening of cycle life.…”
