Journal of The Electrochemical Society, Volume 161,

The effects of vinylene carbonate (VC), fluoroethylene carbonate (FEC) and vinyl ethylene carbonate (VEC) electrolyte additives on electrode/electrolyte reactivity at elevated temperatures were investigated using accelerating rate calorimetry (ARC). Li(Ni 1/3 Mn 1/3 Co 1/3)O 2 (NMC) and graphite (mesocarbon microbeads (MCMB)) were utilized as the electrodes and 1.0 M LiPF 6 in ethylene

Mass production and industrial applications of graphene

INTRODUCTION Graphene has attracted attention worldwide and is considered a promising material for industrial applications. Before the exfoliation of graphene with Scotch tape was reported in 2004 [], several groups had exfoliated graphite to thin platelets [2, 3], and identified 'single-layer graphite' on noble metal surfaces as grown by chemical vapor deposition (CVD) [].

History of the glass electrode

The history of the glass electrode enjoys a thorough and well-developed exploration in a 2011 article by Fritz Scholz, from which much of this information is derived. Generally speaking, the explanation of a concept like this probably benefits from an exploration of its

Failure Mechanisms in Li

Failure Mechanisms in Li- and Na-ion Conversion Electrodes Dr Alex W Robertson and Prof Mauro Pasta The current generation of Li-ion batteries use intercalation electrodes, such as graphite at the anode, where the Li ions physically insert themselves between the electrode layers to store charge.

A Review Covering The Discovery, Structure, Production,

The first commercial production technique was the Kratschmer-Huffman arc discharge technique, from 1990 which used graphite electrodes. This technique primarily produces C 60 and C 70 but could be modified to produce larger fullerenes.

Negative electrodes for lithium cells and batteries

Lithiated graphite electrodes operate at a potential very close to that of metallic lithium and are extremely reactive. There is, therefore, a need to find alternative electrodes to graphite. According to this invention, there is described a new intermetallic structure type that can be effectively used as a negative electrode (anode) for a non-aqueous lithium electrochemical cell and/or battery.

Graphene based biosensors—Accelerating medical

A. Brief history of biosensors 'Biosensor' is a very broad field and known to have many terminologies and definitions that entirely depend on the method of transduction (i.e., optical, mechanical, or electrical) or the bio-receptor used [i.e., catalytic (enzyme) or affinity based (aptamer, antibody, lectin, bacteriophages etc.)].

Graphene: history, controversy and the Nobel prize

Furthermore, they managed to pattern samples containing only a few layers of graphene into a Hall bar and connect electrodes to it. Many voices were heard surrounding the Nobel committee's decision to grant the 2004 graphene-related prize, and disputes over the history of the field ran rampant.

US Patent for Process for the production and treatment

Particularly, the development of graphite for anodes in Li-ion batteries has seen increased attention in this domain. The Acheson technology (U.S. Pat. No. 933,944) developed in the early 20th century describes a process for heat treatment of carbonaceous materials by resistive heating.
