In this paper, the application of a Graphene oxide (GRPox) integrated on single-use pencil graphite electrode (PGE) for the enhanced monitoring of nucleic acids and for the sensitive and selective detection of the label free DNA hybridization related to Hepatitis B virus (HBV) sequences is described. Electrochemical behaviors of GRPox modified PGEs were firstly investigated using electrochemica...

It is well known that when propylene carbonate (PC) is used as the primary solvent with common inorganic salts like LiPF6 there is essentially continuous electrolyte reduction with a graphite electrode at ca. 0.9 V vs. Li/Li, accompanied by gassing and graphite exfoliation. However, co-intercalation and subsequent reduction occurs only with PC and not the chemically closely related solvent ethy...

Lithium Bis(trimethylsilyl) Phosphate (LiTMSP) was incorporated as an electrolyte additive in LiNi 0.8 Co 0.1 Mn O 2 (NCM811)/graphite cells for improving the low-temperature performance. Previously, we reported bi-functional roles of LiTMSP 0.5 1.5 4 /graphite cells, which are hydrogen fluoride (HF) scavenger and film-forming agent. In this work, NCM811/graphite with (1 wt%) have better rate p...

The nucleation and growth mechanisms of porous MnO₂ coating deposited on graphite in MnSO₄ solution were investigated in detail by cyclic voltammetry, chronoamperometry and scanning electron microscopy. The electrochemical properties of honeycomb-like MnO₂ were evaluated by cycle voltammetry and galvanostatic charge-discharge. Results indicated that MnO₂ was synthesized by the following steps: ...

The cyclic stress in lithium-ion battery electrodes induced by repeated charge and discharge cycles causes electrode degradation and fracture, resulting in reduced battery performance and lifetime. To investigate electrode mechanics as a function of electrochemical cycling, we utilize digital image correlation (DIC) to measure the strains that develop in lithium-ion battery electrodes during li...
