Lithium Manganese Oxide ( LiMn2O4 ) Powder for Li-ion Battery Cathode Applications

One of the components that can be used as cathode materials in lithium ion batteries is lithium manganese oxide. Lithium Manganese Oxide ( LiMn2O4 ) Powder for Li-ion Battery Cathode Application provide a low cost and it is an environmental friendly cathode material.
In lithium ion batteries manganese is one of the most common transition metals used because of having multiple oxidation states, which leads the possibility to intercalate more than one lithium atom, and obtaining a wide potential range between depending on the crystal structure and the chemical composition. Being not toxic and highly available makes manganese a good material can be used in lithium ion batteries.
Manganese may have oxidation states of 2+, 3+ and 4+. With different oxidation states of manganese it is possible to obtain different geometries that can be used in lithium ion batteries. Depending on the geometry around the central metal ion and its oxidation state, the manganese gives the possibility to exploit a higher number of redox couples which are not possible to be exploited with other transition metal elements. This situation is extremely important for the design of new materials for Li-ion batteries.
But manganese-based cathode materials may have a problem related to their stability because of Mn2+ dissolution in the electrolyte and the Jahn-Teller effect of the Mn3+ ion which limits their cycle life. Of course scientist have worked on this problem and they have found some solutions. These solution include doping or surface coating. Another aspect for this situation is to develop composite electrodes using structurally integrated layered Li2MnO3 and spinel LiMn2O4. The combination of these two structures provides increased structural stability during electrochemical cycling while achieving higher capacity and rate-capability.

Improving Dialysis Process with Graphene

Researchers from Mechanical and Electrical Engineering Departments of MIT recently showed that graphene is a powerful material candidate for use in the dialysis systems (such as hemodialysis machines in medical institutes for filtering human blood). In order to prepare graphene as a dialysis material, researchers used a procedure opposite to the general treatments that nanotechnology people use. Dialysis is a process of filtering different solutions such as human blood by a membrane in order to remove waste molecules, drugs, chemical residues from the solution. In some cases, the process can be used for purification of chemicals or isolation of different molecules for medical diagnosis. It is an essential process for scientists especially in the medical operations.

Graphene Oxide Dispersion

Graphene oxide refers to a mono-atomic layer material obtained when graphite crystals are oxidized. This is one of the graphene materials that are commercially available because of  its ability to dissolve in water  which makes the oxidation process suitable. In this article, we will talk about the  synthesis, the properties and some of the applications of graphene oxide dispersion in water . Seven Properties of Graphene Oxide Dispersion The properties of a material are defined through its structure, however, this material is very peculiar, since there is no unambiguous model of this material. Graphene Oxide dispersion offers remarkable physical, chemical and mechanical properties that give the opportunity to new applications. Graphene Oxide is amorphous , but, in general, graphene oxide can be described as a two-dimensional sheet containing honeycomb carbon atoms with functional groups of hydroxide and oxygen, unlike the graphene model that seeks to completely re...
