Reassessment of the roles of Ag in TiO2 nanotubes anode material for lithium ion battery

Binder-free combination of amorphous TiO2 nanotube arrays with highly conductive Cu bridges for lithium ion battery anode

“…Preparation of Cu-modified amorphous TiO 2 nanotube arrays Firstly, amorphous TiO 2 nanotube arrays were prepared via facile anodization in a two-electrode cell, as reported in our previous work [9]. Secondly, Cu-modified amorphous TiO 2 nanotube arrays were fabricated by one-step in situ electrodeposition of Cu at −1.5 V for 100 s in a three-electrode cell with the electrolyte containing 0.01 M CuSO 4 and 0.02 M H 2 SO 4 .…”

“…On one hand, the nanostructures with large surface area were built to improve the cycling stability and shorten the pathway of the charge transport [8]. For example, self-organized 3D oriented hollow TiO 2 nanotube arrays via facile anodization would be preferable for microbattery, mainly due to larger surface area and the intimate combination with Ti substrate [9]. On the other hand, the combinations of TiO 2 anode with conductive materials were also an effective strategy for improving electrochemical performance, such as Ag [9], graphene [10], and V [11].…”

Conformal electrodeposition of poly(phenylene oxide) on TiO2 nanotube arrays with high performance for lithium ion battery

“…Firstly, TiO 2 NT was prepared via facile anodization in a two‐electrode cell, as reported in our previous work . Electropolymerization of phenol was performed by CV and chronoamperometry in a three‐electrode cell containing 0.02 M phenol and 0.1 M Na 2 SO 4 , where the as‐prepared TiO 2 NT was used as the working electrode, a saturated calomel electrode as the reference electrode, and Pt foil as the counter electrode, respectively.…”

Composite sodium p‐toluene sulfonate–polypyrrole–iron anode for a lithium‐ion battery

“…The lithium‐ion battery (LIB) is well known as a promising energy storage and conversion technology because of its high energy density, long‐cycle life span, and environmental friendliness . Graphite is the most common anode active material in commercial LIB, but the easy formation of hazardous Li dendrites during the charge–discharge cycle also hinders the innovation of compact LIB with a high energy density and safety rating . Therefore, many alternative anode materials such as Si‐based materials, metal‐based materials (Sn, Al, Ge, etc.…”
