Aluminium-ion Battery
Aluminium-ion batteries (AIB) are a class of rechargeable battery in which aluminium ions serve as charge carriers. Aluminium can exchange three electrons per ion. This means that insertion of one Al3+ is equivalent to three Li+ ions. Thus, since the ionic radii of Al3+ (0.54 Å) and Li+ (0.76 Å) are similar, significantly higher numbers of electrons and Al3+ ions can be accepted by cathodes with little damage. Al has 50 times (23.5 megawatt-hours m-3) the energy density of Li-ion batteries and is even higher than coal. The trivalent charge carrier, Al3+ is both the advantage and disadvantage of this battery. While transferring 3 units of charge by one ion significantly increases the energy storage capacity, the electrostatic intercalation of the electrodes with a trivalent cation is too strong for well-defined electrochemical behaviour. Theoretically, the gravimetric capacity of Al-ion batteries is 2980 mAh/g while its volumetric capacity would be 8046 mAh/ml for th ...

Lithium-ion Battery
A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li+ ions into electronically conducting solids to store energy. Li-ion batteries are characterized by higher specific energy, energy density, and energy efficiency and a longer cycle life and calendar life than other types of rechargeable batteries. Also noteworthy is a dramatic improvement in lithium-ion battery properties after their market introduction in 1991; over the following 30 years, their volumetric energy density increased threefold while their cost dropped tenfold. In late 2024 global demand passed per year, while production capacity was more than twice that. The invention and commercialization of Li-ion batteries has had a large impact on technology, as recognized by the 2019 Nobel Prize in Chemistry. Li-ion batteries have enabled portable consumer electronics, laptop computers, cellular phones, and electric cars. Li-ion batteries also see signifi ...

Birla Institute Of Technology, Mesra
Birla Institute of Technology, Mesra (BIT, Mesra) is a government funded technical institute (GFTI) situated at Ranchi, Jharkhand, India. It was declared as a deemed university under Section 3 of the UGC Act. The institute was included under Section 12B of the UGC Act, 1956, in November 2023. History The Birla Institute of Technology was established in 1955 at Mesra by industrialist and philanthropist B. M. Birla. The institute was affiliated with Patna University until 1960, and then with Ranchi University. In 1986 BIT was elevated to the status of a deemed university under section 3 of the '' University Grants Commission Act, 1956''. BIT was the first institute in India to set up a department of space engineering and rocketry, in 1964. The Small Industries Research and Development Organization (SIRDO) was set up in 1970 to support small manufacturing enterprises managed by graduates of BIT. Companies created from this concept include Meditron and Alcast. This idea wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MacDiarmid Institute For Advanced Materials And Nanotechnology
The MacDiarmid Institute for Advanced Materials and Nanotechnology (often simply called the MacDiarmid Institute) is a New Zealand Centre of Research Excellence (New Zealand), Centre of Research Excellence (CoRE) specialising in materials science and nanotechnology. It is hosted by Victoria University of Wellington, and is a collaboration between five universities and two Crown Research Institutes.

Non-aqueous
An aqueous solution is a solution in which the solvent is water. It is mostly shown in chemical equations by appending (aq) to the relevant chemical formula. For example, a solution of table salt, also known as sodium chloride (NaCl), in water would be represented as . The word ''aqueous'' (which comes from ''aqua'') means pertaining to, related to, similar to, or dissolved in, water. As water is an excellent solvent and is also naturally abundant, it is a ubiquitous solvent in chemistry. Since water is frequently used as the solvent in experiments, the word solution refers to an aqueous solution, unless the solvent is specified. A ''non-aqueous solution'' is a solution in which the solvent is a liquid, but is not water. Characteristics Substances that are ''hydrophobic'' ('water-fearing') do not dissolve well in water, whereas those that are ''hydrophilic'' ('water-friendly') do. An example of a hydrophilic substance is sodium chloride. In an aqueous solution the hydrogen io ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cobalt Mining
Cobalt is a chemical element; it has symbol Co and atomic number 27. As with nickel, cobalt is found in the Earth's crust only in a chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, somewhat brittle, gray metal. Cobalt-based blue pigments (cobalt blue) have been used since antiquity for jewelry and paints, and to impart a distinctive blue tint to glass. The color was long thought to be due to the metal bismuth. Miners had long used the name ''kobold ore'' (German for ''goblin ore'') for some of the blue pigment-producing minerals. They were so named because they were poor in known metals and gave off poisonous arsenic-containing fumes when smelted. In 1735, such ores were found to be reducible to a new metal (the first discovered since ancient times), which was ultimately named for the ''kobold''. Today, some cobalt is produced specifically from one of a number of me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
