Although lithium metal is an ultimate anode material for lithium-based batteries owing to its high theoretical capacity, the uncontrollable dendrites and infinite volume change associated with poor rate capabilities are stagnating its practical applications. Here, a new type of perpendicular MXene-Li array is developed with tunable MXene walls and constant space in between as anodes for lithium metal batteries. Such perpendicular MXene arrays possess dual periodic interspaces, i.e., nanometer-scale interspaces in MXene walls and micrometer-scale interspaces between MXene walls. The former interspaces are favorable for the fast transfer of lithium ions upon stripping and plating, and the latter enables efficiently homogenization of the electric field, leading to a good high-rate capability up to 20 mA cm −2 . More importantly, the notorious lightning rod effect and volume change are efficiently inhibited in such perpendicular MXene arrays, giving rise to a dendrite-free lithium anode with a low potential of 25 mV, a high capacity of 2056 mAh g −1 , and good cycle stability up to 1700 h. layers [10,11] ), advanced electrolytes (solid electrolytes, [12] hybrid electrolytes [13,14] ) and 3D hosts (nickel foams, [15,16] graphene oxide foams, [17][18][19][20] etc.) have been exploited. In particular, 3D hosts enable to significantly promote the transfer of lithium ions or electrons, dramatically improving the cycle life and inhibiting the volume change during repeated stripping and plating processes. To date, 3D hosts can be simply divided into two categories: insulated hosts and electrically conductive hosts. The insulated 3D hosts commonly include glass fiber (GF) cloths, [21] ZnO coated polyimide matrix, [22] and oxidized polyacrylonitrile nanofiber networks, [23] which can homogenize the lithium flux and enhance the transportation of lithium ions. In comparison, electrically conductive 3D hosts are common carbon nanotube sponges, [24] Cu frameworks, [25] reduced graphene oxide foams, [26] 3D graphitic carbon foams, [27] which enable to homogenize both electrical field and lithium ion flux. However, for above 3D hosts, their pores were usually disordered, far from the ideal ordered structures. Very recently, some hosts with periodic and uniform pores or channels have been explored, including vertically aligned 3D hosts including porous polyimide/lithium arrays, [28] glass fiber/ lithium arrays, [29] Cu microchannels, [30] and vertically oriented lithium-copper-lithium arrays. [31] These periodic upright structures are not only favorable for the fast transfer of both lithium ion and electron, but providing abundant interior spaces for lithium plating. Thus, these vertically aligned hosts show improved high-rate capabilities as applied for lithium-based batteries. Unfortunately, in such 3D hosts, the lightning rod effect becomes more severe, causing substantial lithium dendrites growing at the top end of the aligned walls. [30,31] Moreover, upon deep stripping and plating, lithium is still prone to mainly grow on the ...

“…[14,15] Despite the encouraging progress on the interphase engineering, the intrinsic volume expansions caused by the hostless Li plating/stripping are still detrimental to the SEI stabilization, which inevitably aggravates the Li-metal depletion and accelerates dendrite growth, especially at high current densities and cycling capacities. [16,17] In this regard, 3-dimensional (3D) structures have emerged as a promising host to accommodate Li and relieve the volume changes. [16,18] Besides, based on the Sand's law that the growth of Li dendrites is greatly affected by the local current density, a conductive 3D host with high surface area could spatially reduce the local current density and avoid charge accumulation, beneficially smoothing the Li-ion flux and mitigating the Li dendrite formation.…”

A 3D Lithiophilic Mo₂N‐Modified Carbon Nanofiber Architecture for Dendrite‐Free Lithium‐Metal Anodes in a Full Cell

The pursuit for high-energy-density batteries has inspired the resurgence of metallic lithium (Li) as a promising anode, yet its practical viability is restricted by the uncontrollable Li dendrite growth and huge volume changes during repeated cycling. Herein, a new 3dimensional (3D) framework configured with Mo 2 N-mofidied carbon nanofiber (CNF) architecture is established as a Li host via a facile fabrication method. The lithiophilic Mo 2 N acts as a homogeneously pre-planted seed with ultralow Li nucleation overpotential, thus spatially guiding a uniform Li nucleation and deposition in the matrix. The conductive CNF skeleton effectively homogenizes the current distribution and Li-ion flux, further suppressing the Li-dendrite formation. As a result, the 3D hybrid Mo 2 N@CNF structure facilitates dendrite-free morphology with greatly alleviated volume expansion, delivering a significantly improved Coulombic efficiency of ~ 99.2% over 150 cycles at 4 mA cm-2. Symmetric cells with Mo 2 N@CNF substrates stably operate over 1,500 h at 6 mA cm-2 for 6 mA h cm-2. Furthermore, full cells paired with LiNi 0.8 Co 0.1 Mn 0.1 O 2 (NMC811) cathodes in conventional carbonate electrolytes achieve a remarkable capacity retention of 90% over 150 cycles. This

In this study, we fabricated a cathode with lower amounts of additive materials and higher amounts of active materials than those of a conventional cathode. A thermal battery was fabricated using FeS 2 treated foam as the cathode frame, and its feasibility was verified. X-ray diffraction, transmission electron microscopy, and scanning electron microscopy were used to analyze the effects of thermal sulfidation temperature (400 and 500 • C) on the structure and surface morphology of the FeS 2 foam. The optimal temperature for the fabrication of the FeS x treated foam was determined to be 500 • C. The FeS 2 treated foam reduced the interfacial resistance and improved the mechanical strength of the cathode. The discharge capacity of the thermal battery using the FeS 2 treated foam was about 1.3 times higher than that of a thermal battery using pure Fe metal foam.
