Characterization of Composite 0.5Ag:V[sub 2]O[sub 5] Thin-Film Electrodes for Lithium-Ion Rocking Chair and All-Solid-State Batteries

Electrochemical and structural properties of MoO3–V2O5 nanocomposite thin film electrodes for lithium rechargeable batteries

“…This indicates that the incorporation of MoO 3 nano-dots delays the degradation of the capacity by stabilizing the amorphous V 2 O 5 matrix and so is very effective in enhancing the electrochemical performance of batteries. This is consistent with the results reported previously by other groups [11,[19][20][21], showing that the incorporation of nanostructured electrodes into batteries enhances the electrochemical performance of Li rechargeable batteries.…”

“…However, thin film batteries made with V 2 O 5 cathode electrodes suffer from poor cycling performance, which was attributed to the irreversible reactions of phase transformation and mechanical cracking due to volumetric changes during a charge and discharge process [11,18]. Several groups showed that alloying and doping processes are effective ways for enhancing the electrochemical property of V 2 O 5 thin films [10,11,[19][20][21][22] sputtered films give better cycling performance than undoped films, which was attributed to the absence of short-range order [10,11]. In this work, we have investigated the effect of the addition of nanosized MoO 3 on the structural and electrochemical properties of amorphous V 2 O 5 -based thin film electrodes.…”

“…For example, Chu et al and Huang et al showed that Ag-V 2 O 5 composite films, where nanosized metallic Ag or Ag oxide embedded in a V 2 O 5 matrix, exhibit better cycling performance than single V 2 O 5 films[19,20]. Lee et al investigating how Ag co-sputtering affects the electrochemical properties of amorphous V 2 O 5 thin films for microbatteries showed that the specific capacity and cycling performance of microbatteries become improved with increasing Ag content in the cathode films[21].Kim et al, investigating the effect of Pt co-sputtering on the electrochemical properties of amorphous V 2 O 5 films, showed that Pt co-…”

Effect of silver co-sputtering on V2O5 thin films for lithium microbatteries

“…Despite the promising results obtained for these materials, only few studies have been achieved on doped V 2 O 5 thin films [18][19][20][21]. In the case of silver-doped V 2 O 5 thin films, only three different deposition methods have been used: dip-coating of xerogels [12], pulsed laser deposition [19,22] and co-sputtering [18]. Whatever the deposition technique, all researchers have mentioned an increase of the electronic conductivity due to the silver doping.…”

“…Whatever the deposition technique, all researchers have mentioned an increase of the electronic conductivity due to the silver doping. The dip-coating method as well as the pulsed laser deposition has led to the composition range Ag y V 2 O 5 with 0.1 ≤ y ≤ 0.5 [12,19,22]. Except for Ag 0.1 V 2 O 5 prepared by dip-coating, all the thin films are amorphous.…”
