Lithium-ion battery in the context of "Rechargeable battery"

Grid energy storage, also known as large-scale energy storage, is a set of technologies connected to the electrical power grid that store energy for later use. These systems help balance supply and demand by storing excess electricity from variable renewables such as solar and inflexible sources like nuclear power, releasing it when needed. They further provide essential grid services, such as helping to restart the grid after a power outage.

As of 2023, the largest form of grid storage is pumped-storage hydroelectricity, with utility-scale batteries and behind-the-meter batteries coming second and third. Lithium-ion batteries are well suited for short-duration storage (under 8 hours), due to their lower cost and sensitivity to degradation at high states of charge. Flow batteries and compressed air energy storage may provide storage for medium-duration. Two forms of storage are suited for long-duration storage: green hydrogen, produced via electrolysis and thermal energy storage.

TOGG (stylised as Togg), acronym of Türkiye'nin Otomobili Girişim Grubu (lit. 'Turkey's Automobile Joint Venture Group'), is a Turkish automotive manufacturer of electric cars headquartered in Şişli, Istanbul, Turkey. The company was founded as a joint venture by five Turkish companies in 2018. An assembly plant was opened in 2022 in Gemlik, Bursa province, next to Togg’s subsidiary Siro which produces the lithium-ion batteries. Sales of the first vehicle, the Togg T10X, started in March 2023.

In materials and electric battery research, cobalt oxide nanoparticles usually refers to particles of cobalt(II,III) oxide Co
₃O
₄ of nanometer size, with various shapes and crystal structures.

Cobalt oxide nanoparticles have potential applications in lithium-ion batteries and electronic gas sensors.

Manganese dioxide is the inorganic compound with the formula MnO
₂. This blackish or brown solid occurs naturally as the mineral pyrolusite, which is the main ore of manganese and a component of manganese nodules. The principal use for MnO
₂ is for dry-cell batteries, such as the alkaline battery and the zinc–carbon battery, although it is also used for other battery chemistries such as aqueous zinc-ion batteries. MnO
₂ is also used as a pigment and as a precursor to other manganese compounds, such as potassium permanganate (KMnO₄). It is used as a reagent in organic synthesis, for example, for the oxidation of allylic alcohols. MnO
₂ has an α-polymorph that can incorporate a variety of atoms (as well as water molecules) in the "tunnels" or "channels" between the manganese oxide octahedra. There is considerable interest in α-MnO
₂ as a possible cathode for lithium-ion batteries.

A battery pack is a set of any number of (preferably) identical batteries or individual battery cells. They may be configured in a series, parallel or a mixture of both to deliver the desired voltage and current. The term battery pack is often used in reference to cordless tools, radio-controlled hobby toys, and battery electric vehicles.

Components of battery packs include the individual batteries or cells, and the interconnects which provide electrical conductivity between them. Rechargeable battery packs often contain voltage and temperature sensors, which the battery charger uses to detect the end of charging. Interconnects are also found in batteries as they are the part which connects each cell, though batteries are most often only arranged in series strings.

A battery electric vehicle (BEV), pure electric vehicle, only-electric vehicle, fully electric vehicle or all-electric vehicle is a type of electric vehicle (EV) that uses electrical energy exclusively from an on-board battery pack to power one or more electric traction motors, on which the vehicle solely relies for propulsion.

This definition excludes hybrid electric vehicles (HEVs; including mild, full and plug-in hybrids), which use internal combustion engines (ICEs) in adjunct to electric motors for propulsion; and fuel cell electric vehicles (FCEVs) and range-extended electric vehicles (REEVs), which consume fuel through a fuel cell or an ICE-driven generator to produce electricity needed for the electric motors. BEVs have no fuel tanks and replenish their energy storage by plugging into a charging station, electrical grid or getting a new battery at a battery swap station, and use motor controllers to modulate the output engine power and torque, thus eliminating the need for clutches, transmissions and sophisticated engine cooling as seen in conventional ICE vehicles. BEVs include – but are not limited to – all battery-driven electric cars, buses, trucks, forklifts, motorcycles and scooters, bicycles, skateboards, railcars, boat and personal watercraft, although in common usage the term usually refers specifically to passenger cars.

Cadmium is a chemical element; it has symbol Cd and atomic number 48. This soft, silvery-white metal is chemically similar to the two other stable metals in group 12, zinc and mercury. Like zinc, it demonstrates oxidation state +2 in most of its compounds, and like mercury, it has a lower melting point than the transition metals in groups 3 through 11. Cadmium and its congeners in group 12 are often not considered transition metals, in that they do not have partly filled d or f electron shells in the elemental or common oxidation states. The average concentration of cadmium in Earth's crust is between 0.1 and 0.5 parts per million (ppm). It was discovered in 1817 simultaneously by Stromeyer and Hermann, both in Germany, as an impurity in zinc carbonate.

Cadmium occurs as a minor component in most zinc ores and is a byproduct of zinc production. It was used for a long time in the 1900s as a corrosion-resistant plating on steel, and cadmium compounds are used as red, orange, and yellow pigments, to color glass, and to stabilize plastic. Cadmium's use is generally decreasing because it is toxic, and nickel–cadmium batteries have been replaced with nickel–metal hydride and lithium-ion batteries. Because it is a neutron poison, cadmium is also used as a component of control rods in nuclear fission reactors. One of its few new uses is in cadmium telluride solar panels.
