Production of chlorine-containing functional group doped graphene powders using Yucel's method as anode materials for Li-ion batteries

Abstract

In this study, the one-step electrochemical preparation of chlorine doped and chlorine-oxygen containing functional group doped graphene-based powders was carried out by Yucel's method, with the resultant materials used as anode materials for lithium (Li)-ion batteries.

Preparation of sulfur‐doped graphenes by Yucel's method and their corresponding polylactide‐based nanocomposites

“…While raw graphite exhibited an intense and sharp basal peak (002) at 2𝜃=26.45° (d spacing = 3.37 Å), SG layers represented broad and decreased peak intensities which shifted to lower diffraction angles 45,46 . The 42.3° (100) can be related to the sulfur doping and functional groups on the crystal structure of few‐layered graphene powders 47 . Moreover, the other diffractions peaks of graphene and carbonaceous structures were observed at 55° (004) and 77° (110) respectively due to the different diffraction planes in the structure 48,49 .…”

Recovery of cobalt as CoS from spent Li-ion batteries and investigation of its use as an electrode material for supercapacitors

“…4,5 Secondary batteries, one of these battery types, are also referred to as rechargeable batteries. [6][7][8][9][10] They are reusable and can be recharged by passing electricity through the cells. 11 Examples include lithium-ion batteries used in devices including laptops, phones, and electric cars.…”

A new approach to prepare N‐/S‐doped free‐standing graphene oxides for vanadium redox flow battery

“…The solution to this problem involves using advanced electrochemical energy storage technologies such as batteries and supercapacitors. [4][5][6][7][8][9][10] Nowadays, scientists focus on two promising systems for large-scale energy storage demands lithium-ion (LIB) and redox flow batteries (RFB). However, while LIBs have approximately 10-15 years with a 3000 cycle lifetime, RFBs are durable up to 20 000 cycles.…”

“…For example, in solar energy, electrical energy production depends on sunlight.
