“…In addition to the morphological control of the anode particles, the introduction of a surface coating layer on these particles improved the interfacial stability by preventing direct contact of the anodes with SEs. To date, the cycling stability and energy density of ASSLBs have been significantly enhanced by incorporating various surface coating media such as metal oxides and artificial SEI layers on the anode particles …”

Advances and Prospects of Sulfide All‐Solid‐State Lithium Batteries via One‐to‐One Comparison with Conventional Liquid Lithium Ion Batteries

Owing to the safety issue of lithium ion batteries (LIBs) under the harsh operating conditions of electric vehicles and mobile devices, all‐solid‐state lithium batteries (ASSLBs) that utilize inorganic solid electrolytes are regarded as a secure next‐generation battery system. Significant efforts are devoted to developing each component of ASSLBs, such as the solid electrolyte and the active materials, which have led to considerable improvements in their electrochemical properties. Among the various solid electrolytes such as sulfide, polymer, and oxide, the sulfide solid electrolyte is considered as the most promising candidate for commercialization because of its high lithium ion conductivity and mechanical properties. However, the disparity in energy and power density between the current sulfide ASSLBs and conventional LIBs is still wide, owing to a lack of understanding of the battery electrode system. Representative developments of ASSLBs in terms of the sulfide solid electrolyte, active materials, and electrode engineering are presented with emphasis on the current status of their electrochemical performances, compared to those of LIBs. As a rational method to realizing high energy sulfide ASSLBs, the requirements for the sulfide solid electrolytes and active materials are provided along through simple experimental demonstrations. Potential future research directions in the development of commercially viable sulfide ASSLBs are suggested.

“…[6] The Li dendrite formation is due to the cracks formed in the insoluble solid-electrolyte interphase (SEI) layer between Li metal and electrolyte, as a result of drastic volume changes during continuous Li stripping/plating. [9,10] Various routes have thus been developed to restraint he growth of dendrites, including stabilizing the SEI layer by optimizingt he solvents, [11] lithiums alts, [4,12,13] and/ore lectrolyte additives; [14,15] introducing high-modulus solid electrolytes (such as lithium garnets [16][17][18] and composite electrolyte [19] )t op hysically impede dendrite infiltration;a nd building an interface layer on the lithium metal as an artificial protective SEI layer [20] (such as SiO 2 , [21] Al 2 O 3 , [22][23][24] LiF, [25,26] and polymer [27] ). [3] These decompositionr eactions lead to increasingi nternal resistance, low Coulombic efficiency (CE), and bad cycling performance of LIBs.…”

Low‐Weight 3D Al₂O₃ Network as an Artificial Layer to Stabilize Lithium Deposition

et al. 2018

Lithium metal has been regarded as an ideal anode for high-energy-density batteries. However, safety and efficiency concerns still linger due to dendrite formation, reactions between the liquid electrolyte and lithium, high resistance with lithium metal, and the weight of interface layer. A new nanometer-thick, hollow, Al O fiber network with an elastic and porous 3D structure has been prepared through an atomic-layer deposition process by using cotton sacrificial templates. Through a comparison study of the lithium deposition behavior by employing artificial layers with different structures, the low-weight 3D layer with lithiophilic properties overcomes the issues resulting from the 2D rigid Al O layer and provides a low overpotential and dendrite-free growth of lithium metal. Moreover, stable lithium deposition enables Li-Li symmetric cells with a 3D artificial layer to be stably cycled 300 times in carbonate-based electrolyte, with superior rate capability, and with a LiNi Co Mn O cathode.

“…This repeated breakage and repair of the SEI layers will continuously consume both Li metal and electrolyte, leading to lower coulombic efficiency and poorer cycling performance [15]. Many efforts have been made to improve the performance of Li metal by modifying the Li metal surface [16,17]. Wang et al deposited a 30 nm amorphous Li 3 PO 4 thin film on a Li metal surface via magnetron sputtering to suppress the lithium dendrite growth and improve the battery life span [18].…”

Li-B Alloy as an Anode Material for Stable and Long Life Lithium Metal Batteries

et al. 2018

View full text Add to dashboard Cite

Rechargeable Li metal batteries have attracted lots of attention because they can achieve high energy densities. However, the commercialization of rechargeable Li metal batteries is delayed because Li dendrites may be generated during the batteries' electrochemical cycles, which may cause severe safety issues. In this research, a Li-B alloy is investigated as an anode for rechargeable batteries instead of Li metal. Results show that the Li-B alloy has better effects in suppressing the formation of dendritic lithium, reducing the interface impedance and improving the cycle performance. These effects may result from the unique structure of Li-B alloy, in which free lithium is embedded in the Li 7 B 6 framework. These results suggest that Li-B alloy may be a promising anode material applicable in rechargeable lithium batteries.
