The cathode is the positive electrode of a battery and the component that most defines its performance, setting the cell voltage, supplying most of the energy density, and typically accounting for the largest share of cell cost. In a lithium-ion battery the choice of cathode chemistry decides whether a cell prioritizes range, safety, power, or price. This guide explains what cathode materials are, the properties that make a good one, the main chemistries used in 2026, and the applications each o …

The anode is the negative electrode of a battery, the component that stores lithium ions while the cell is charged and releases them during discharge to deliver current. In a lithium-ion cell the anode material sets a hard ceiling on energy density, charging speed, and cycle life, which is why it is one of the most studied components in modern energy storage. This guide explains what anode materials are, the properties that define a good one, the main material families used in 2026, and the appl …

Introduction Carbon is a versatile element that occurs naturally in several allotropic forms, such as diamond and graphite. In 1985 a new member joined this family: fullerenes, hollow cage-like carbon molecules built entirely from pentagonal and hexagonal faces. Notable for their symmetric, soccer-ball-like architecture, these molecules opened a new field of research in chemistry, materials science, and nanotechnology from the moment they were discovered. Today, fullerenes find applications acro …

This article mainly discusses two of the methods used for the preparation of the nanoparticles and nanocomposite particles. Apart from the nanoparticles and nanocomposite particles, these methods can be utilized in the production of different metallic, metallic oxides, metallic alloys nanomaterials, carbon nanomaterials, etc. Both methods use bottom-up approach out of the two approaches (top-down, bottom-up) for the preparation of the nanoparticles and nanocomposite particles. Inert G …

At present, lithium batteries are the most widespread types of energy accumulator in the world and are used in a huge diversity of implementations, including smartphones, notebooks, tablets, and many other devices that require a reliable battery and with a large performance. That is why lithium batteries are the most chosen accumulator among manufacturers and developers worldwide, precisely because of their energy efficiency, without a doubt, it is the most important variable when it comes to po …
