Metal–Organic Coordination Strategy for Obtaining Metal‐Decorated Mo‐Based Complexes: Multi‐dimensional Structural Evolution and High‐Rate Lithium‐Ion Battery Applications

Abstract

Metal-organic assemblies for electrodes:Anew metal-organic coordination strategy tuned by as urfactant is presented for the design of Mo-based hybrid materials ranging from 2D nanopetals to 3D microflowers. The new lithium-ion battery (LIB) of Ni-MoO 2 /N-C j Li-Ni 0.6 Co 0.2 Mn 0.2 O 2 with high rate features above 8Cis introduced. This strategy is applicable for greater capabilities, and the high-rate LIB can meet the requirements of fast-charging energy storage devices.Chem. Eur.J.

Large-Sized Nickel–Cobalt–Manganese Composite Oxide Agglomerate Anode Material for Long-Life-Span Lithium-Ion Batteries

“…The contribution ratio of battery and capacitive behavior can be calculated by dividing the total current i into the capacitive and diffusion-controlled parts. There is a calculation formula i = k 1 v + k 2 v 1/2 ( k 1 and k 2 are constants), where the capacitive behavior corresponds to k 1 v and the battery behavior corresponds to k 2 v 1/2 . We calculate that the capacitive behavior contributes 48.7% to the total capacity of the Ni 0.6 Co 0.2 Mn 0.2 O x electrode at the 0.5 mV s –1 sweep rate (Figure c).…”

“…There is a calculation formula i = k 1 v + k 2 v 1/2 (k 1 and k 2 are constants), where the capacitive behavior corresponds to k 1 v and the battery behavior corresponds to k 2 v 1/2 . 17 We calculate that the capacitive behavior contributes 48.7% to the total capacity of the Ni 0.6 Co 0.2 Mn 0.2 O x electrode at the 0.5 mV s −1 sweep rate (Figure 5c). The ratio of the capacity contribution for different sweep rates is also calculated (Figure 5d), and it can be seen that the contribution of the capacitive behavior gradually increases.…”

“…Metal oxides, , metal sulfides, silicon, tin, antimony, and other anode materials , have become current research hotspots because of their higher specific capacity and are committed to becoming a substitute for commercial graphite anodes. In particular, transition-metal-oxide-based anode materials (e.g., NiO, MnO, CoO, and MoO 2 , etc.) have received widespread attention due to the low-cost advantages, high theoretical specific capacity, and simple synthesis methods.…”

“…The large rst irreversible capacity is likely due to the formation of SEI lm. 35,56,57 Fig. 6c and d comparatively displays the rate performances of the O-DS-WS 2 /NSG electrode with different temperatures and pristine WS 2 .…”

An Empirical Model for the Design of Batteries with High Energy Density

“…This is mostly due to the low capacity of electrode materials such as graphite (372 Ah kg -1 ), which is believed to be the main bottleneck. 12,13 Thus, many high capacity alternatives (e.g., metal oxides [14][15][16] , Si/C-based anodes, [17][18][19] Li-based anode, [20][21][22] highvoltage LiNi 1-x-y Co x Mn y O 2 (NCM), and spinel oxide cathodes, [23][24][25] ) have been widely evaluated.…”
