Template-Directed Materials for Rechargeable Lithium-Ion Batteries

Abstract

Extensive research activities have been directed to develop flexible rechargeable lithium-ion batteries with large capacity, high power, and long cycling life. Template technology offers the benefits in terms of either designing new-type electrode materials or modifying traditional battery configurations. With the aid of "hard" or "soft" templates, a variety of functional materials with diverse structures and morphologies such as one-dimensional (1D) nanostructures, 2D films, and 3D porous frameworks have been synthesized. This review highlights the recent progress in the template-prepared electrode materials for lithium storage, mainly focusing on the Li + intercalation reactions and the Li conversion properties with the nanostructures of LiCoO 2 , C, SnO 2 , Fe 2 O 3 , Co 3 O 4 , VO x , and MnO 2 . In some specifically demonstrated examples, the templated cathode materials (e.g., lithium metal oxides) show significantly improved reversibility and high rate capability over a voltage of 3 V after 100 cycles, whereas the templated anode materials (e.g., metal oxides) can deliver high capacity exceeding 1000 mA h g -1 . The structural and morphological merits of the template-directed materials have been especially addressed in comparison with their traditional bulk forms.

3D Porous Cu–Zn Alloys as Alternative Anode Materials for Li‐Ion Batteries with Superior Low T Performance

“…[1][2][3][4] In particular, 3D hierarchical porosity and open, ramified micro/nanostructures with large surface to volume ratios offer easy solution permeation, fast interfacial kinetics, and large capacity/energy density. In comparison with carbonaceous materials, formation of Li alloys warrants also higher power density due to superior lithium diffusivity.…”

Effective use of flexible low-dimensional colloidal particles and colloidal crystals for the control of hierarchically porous materials

“…Inorganic porous materials are applicable in many fields, including catalysis, 1) adsorption, 2) separation, 3) chromatography, 4) sensors, 5) supercapacitors, 6) energy storage, 7) drug delivery systems, 8) and so on, because of their high surface area, size selective inclusion of guest molecules, storage, controlled release, and low dielectric constants. The size and geometry of nanospace have significant effects on these properties.…”

Facile synthesis and magnetic properties of manganese dioxide nanowires

“…As an important functional inorganic material, manganese dioxide (MnO 2 ) has numerous applications in catalysis, ion exchange, molecular adsorption, rechargeable batteries and supercapacitors [15][16][17][18][19][20][21][22][23]. Recently, much attention has focused on the synthesis of 1D MnO 2 nanostructures because of its promising applications in catalysis, rechargeable batteries, ion sieves and supercapacitors [24][25][26][27][28][29][30].…”
