Unique Double Carbon Protection Structured Co<sub>3</sub>O<sub>4</sub> Anode for Lithium Ion Battery

“…Some reported Co 3 O 4 -based nanostructures in the last two years are listed in Table 1. By contrast, the cycling performance of Carbon aerogel (CA)/Co 3 O 4 /Carbon (C) is higher than those of Co 3 O 4 nanocage/Co 3 O 4 nanoframework/TiO 2 [12], Co 3 O 4 nanocubes [13], Hollow Co-Co 3 O 4 /CNTs [14], Co 3 O 4 /nitrogen-doped carbon composite [15] and Co 3 O 4 nanocomposite [19]. But, it is admirable that Co 3 O 4 /nitrogen-doped carbon composite in reference [16], Co/Co 3 O 4 nanoparticles in reference [17] and porous Mn-Co 3 O 4 /C microspheresin reference [18] show super cyclability and rate capability.…”

Ultrafast and Stable Lithium Storage Enabled by the Electric Field Effect in Layer-Structured Tablet-Like NH4TiOF3 Mesocrystals

“…The XPS O 1s spectra (Figure b) contain three peaks, which centered at 530.1, 531.4, and 533.1 eV. The peaks relate to lattice oxygen (O L ), defect oxygen or oxygen vacancies (O V ), and absorbed oxygen on the surface (O W ). ,, The formation of O V is because of the calcination in a poor oxygen atmosphere. In this case, the amount of oxygen atoms is limited to react with Ti atoms to form TiO 2 .…”

Hydrazine Hydrate Induced Three-Dimensional Interconnected Porous Flower-like 3D-NiCo-SDBS-LDH Microspheres for High-Performance Supercapacitor

“…Several modification methods, such as thermal annealing treatment [28][29][30], acid etching [31] or alkali etching [32], NaBH 4 reduction treatment [26,33,34], and hydrazine hydrate reduction treatment [24,25,35], have been reported in previous studies to generate the defective structures in electrode materials. Among these methods, hydrazine hydrate as a mild reducer has received considerable attention.…”
