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.

Hydroxyapatite Nanopowders and Their Applications

Hydroxyapatite, is a naturally occurring mineral form of calcium apatite with the formula Ca 5 (PO 4 ) 3 (OH). Pure hydroxyapatite powder is white. Naturally occurring apatites can, however, also have brown, yellow, or green colorations, comparable to the discolorations of dental fluorosis. Hydroxyapatite Nanopowder/Nanoparticles (50 nm, 99.95+%)  has been widely used as a biocompatible ceramic in many areas of medicine, but mainly for contact with bone tissue, due to its resemblance to mineral bone. In mammals, the skeleton presents a carbonated and partially substituted apatite, based on nanocrystal aggregates, and associated with collagen, building up 3-D structures present in various bone tissue conformations like trabecular or cancellous bone. There has been growing interest in developing bioactive synthetic ceramics that could closely mimic natural apatite characteristics. As mentioned before,  Hydroxyapatite Nanopowder  is the main inorganic constituent of bon...

Carbon Nanotubes Specifications and Properties Carbon Nanotubes, simply CNTs, are allotropes of carbon with a round and hollow nanostructure. These barrel shaped carbon molecules have crucial properties, which are significant for nanotechnology, hardware, optics and other different fields of materials science and innovation. The carbon nanotube’s excellent quality as a strong and firm material laid the basis on many applications. Not to mention carbon nanotubes exceptional heat conductivity, electrical and mechanical properties, Carbon Nanotubes are used as additives to diverse auxiliary materials. In terms of rigidity and flexibility Carbon Nanotubes are the stiffest and strongest materials. These quality outcomes from the covalent sp2 bonds framed between the individual carbon molecules. Unlike Graphene , Carbon Nanotubes are either conductive or semiconducting along the tubular hub. Carbon Nanotubes also have absorption, fluorescence properties. Bulk Carbon nanotubes are util...
