Electrochemistry guides: cells, batteries, Nernst equation and electrode reactions, from lithium-ion to lead-acid and nickel.
Few technologies have had a larger impact on our everyday lives compared to the lithium battery. This technology is notable for its high energy density and low cost per cycle. Helping set them apart from other battery types. However, the term “lithium battery” can be vague as there are around six common chemistries. Each of…
Nickel battery technologies have revolutionized the way we store and use energy, offering a range of solutions for various applications. From the early days of nickel-cadmium (NiCd) batteries to the more advanced nickel-metal hydride (NiMH) and nickel-hydrogen (NiH2) variants, these technologies have continually evolved to meet the growing demands for efficient, reliable, and environmentally friendly…
Conventional vehicles typically rely on Lead Acid Car Battery due to their high power output and affordability. These batteries use water-based electrolytes and have individual cell voltages that are relatively low. While they offer proven safety, lead-acid batteries have a lower specific energy compared to lithium-ion types. In contrast, hybrid electric vehicles often use nickel-metal…
Electrochemistry is the exploration of chemical reactions that induce the motion of electrons, which is called electricity. It is a highly interdisciplinary field with applications spanning physical, chemical, and biological sciences. Today, we are going to explore various areas where electrochemistry plays a crucial role. These include energy conversion and storage, focusing on fuel cells…
Abstract The Li-ion Second Life Batteries application is of growing interest with significant potential to address sustainability and environmental challenges. By 2040, an estimated 3.4 million kilograms of LIB cells from electric vehicles (EVs) could potentially enter the waste stream. However, these batteries still have many useful years ahead of them. Instead of being trashed,…
Think of a battery as a small, portable power plant: it stores energy chemically and releases it as electricity whenever a device needs it. More formally, an electric battery is an energy storage device comprising one or more electrochemical cells. These cells have external connections used to power electrical devices. When providing power, the battery’s…
A diode is a semiconductor device that allows current to flow in one direction, serving as a one-way current switch. Diodes, also called rectifiers, convert alternating current (AC) into pulsating direct current (DC). They are categorized by type, voltage, and current capacity. With polarity determined by an anode (positive) and cathode (negative), diodes typically conduct…
A fuel cell is a device that converts chemical energy directly into electrical energy, water, and heat through electrochemical reactions. It consists of an anode and a cathode separated by an electrolyte, which is typically a porous membrane. Hydrogen, and air (or oxygen) are fed into the cell. At the anode, the fuel undergoes a…
Solar energy refers to any form of energy produced by the sun. It is generated through the process of nuclear fusion that occurs within the sun. Solar radiation, also called electromagnetic radiation, is the light emitted by the sun due to nuclear fusion. Although every location on Earth receives sunlight throughout the year. The intensity…
Energy storage refers to the process of capturing energy generated at one point in time for later use, helping to balance disparities between energy demand and production. Devices designed for this purpose are commonly known as accumulators or batteries. Energy storage entails converting energy from less manageable forms into more easily stored and economically viable…
