Renata AG SA (Renata Batteries), based in Itingen, Switzerland, is a developer and manufacturer of batteries (particularly coin or button cells). It is a subsidiary of The Swatch Group. [1]
Battery technologies offered by Renata comprise silver oxide (for wristwatches, calculators and small electronic toys, etc.), zinc air (for hearing aids), lithium (non-rechargeable, primary) (for computer battery backup, etc.) and battery holders, as well as lithium polymer (rechargeable, secondary) (for industrial use). [2]
Renata was founded in 1952 by Kurt Zehntner, as a manufacturer of components for mechanical watches and diversified into production of coin or button cells in 1974. Renata was acquired by SMH Swiss Corporation for Microelectronics and Watchmaking Industries Ltd in 1982 (in 1998, SMH became known as The Swatch Group) [1] and produces cells, batteries and associated encapsulation technologies and cell/battery holders. [3]
Renata claims to be "one of the three largest producers of coin cells worldwide" [3] and also claims that it produces over one million batteries a day.
A watch is a portable timepiece intended to be carried or worn by a person. It is designed to keep a consistent movement despite the motions caused by the person's activities. A wristwatch is designed to be worn around the wrist, attached by a watch strap or other type of bracelet, including metal bands, leather straps, or any other kind of bracelet. A pocket watch is designed for a person to carry in a pocket, often attached to a chain.
The Swatch Group Ltd is a Swiss manufacturer of watches and jewellery. The company was founded in 1983 by the merger of ASUAG and SSIH to move to manufacturing quartz-crystal watches to resolve the quartz crisis threatening the traditional Swiss watchmaking industry.
A rechargeable battery, storage battery, or secondary cell, is a type of electrical battery which can be charged, discharged into a load, and recharged many times, as opposed to a disposable or primary battery, which is supplied fully charged and discarded after use. It is composed of one or more electrochemical cells. The term "accumulator" is used as it accumulates and stores energy through a reversible electrochemical reaction. Rechargeable batteries are produced in many different shapes and sizes, ranging from button cells to megawatt systems connected to stabilize an electrical distribution network. Several different combinations of electrode materials and electrolytes are used, including lead–acid, zinc–air, nickel–cadmium (NiCd), nickel–metal hydride (NiMH), lithium-ion (Li-ion), lithium iron phosphate (LiFePO4), and lithium-ion polymer.
Duracell Inc. is an American manufacturer of alkaline batteries, specialty cells, and rechargeables; it is a wholly owned subsidiary of Berkshire Hathaway. The company has its origins in the 1920s, through the work of Samuel Ruben and Philip Mallory, and the formation of the P. R. Mallory Company.
An alkaline battery is a type of primary battery where the electrolyte has a pH value above 7. Typically these batteries derive energy from the reaction between zinc metal and manganese dioxide.
The AAA battery is a standard size of dry cell battery. One or more AAA batteries are commonly used in low-drain portable electronic devices. A zinc–carbon battery in this size is designated by IEC as R03, by ANSI C18.1 as 24, by old JIS standard as UM-4, and by other manufacturer and national standard designations that vary depending on the cell chemistry. The size was first introduced by The American Ever Ready Company in 1911. They're called #7 batteries in China, the name originating from the Burgess Battery Company designating his AAA batteries "Number 7".
The AA battery is a standard size single cell cylindrical dry battery. The IEC 60086 system calls the size R6, and ANSI C18 calls it 15. It is named UM-3 by JIS of Japan. Historically, it is known as D14, U12 – later U7, or HP7 in official documentation in the United Kingdom, or a pen cell.
A zinc–air battery is a metal–air electrochemical cell powered by the oxidation of zinc with oxygen from the air. During discharge, a mass of zinc particles forms a porous anode, which is saturated with an electrolyte. Oxygen from the air reacts at the cathode and forms hydroxyl ions which migrate into the zinc paste and form zincate, releasing electrons to travel to the cathode. The zincate decays into zinc oxide and water returns to the electrolyte. The water and hydroxyl from the anode are recycled at the cathode, so the water is not consumed. The reactions produce a theoretical voltage of 1.65 Volts, but is reduced to 1.35–1.4 V in available cells.
Lithium metal batteries are primary batteries that have metallic lithium as an anode. The name intentionally refers to the metal to as to distinguish them from lithium-ion batteries, which use lithiated metal oxides as the cathode material. Although most lithium metal batteries are non-rechargeable, rechargeable lithium metal batteries are also under development. Since 2007, Dangerous Goods Regulations differentiate between lithium metal batteries and lithium-ion batteries.
A button cell, watch battery, or coin battery is a small single-cell battery shaped as a squat cylinder typically 5 to 25 mm in diameter and 1 to 6 mm high – resembling a button. Stainless steel usually forms the bottom body and positive terminal of the cell; insulated from it, the metallic top cap forms the negative terminal.
Vectrix was an electric vehicle company based in Middletown, Rhode Island, United States, with research and development facilities in New Bedford, Massachusetts and an assembly plant in Wrocław, Poland. Vectrix ceased all US operations as of December 31, 2013. The company filed for bankruptcy and final liquidation in March 2014.
The Directive 2006/66/EC of the European Parliament and of the Council of 6 September 2006 on batteries and accumulators and waste batteries and accumulators and repealing Directive 91/157/EEC, commonly known as the Battery Directive, regulates the manufacture and disposal of batteries in the European Union with the aim of "improving the environmental performance of batteries and accumulators".
The lithium iron phosphate battery or LFP battery is a type of lithium-ion battery using lithium iron phosphate as the cathode material, and a graphitic carbon electrode with a metallic backing as the anode. Because of their low cost, high safety, low toxicity, long cycle life and other factors, LFP batteries are finding a number of roles in vehicle use, utility-scale stationary applications, and backup power. LFP batteries are cobalt-free. As of September 2022, LFP type battery market share for EVs reached 31%, and of that, 68% was from Tesla and Chinese EV maker BYD production alone. Chinese manufacturers currently hold a near monopoly of LFP battery type production. With patents having started to expire in 2022 and the increased demand for cheaper EV batteries, LFP type production is expected to rise further and surpass lithium nickel manganese cobalt oxides (NMC) type batteries in 2028.
Battery recycling is a recycling activity that aims to reduce the number of batteries being disposed as municipal solid waste. Batteries contain a number of heavy metals and toxic chemicals and disposing of them by the same process as regular household waste has raised concerns over soil contamination and water pollution. While reducing the amount of pollutants being released through disposal through the uses of landfill and incineration, battery recycling can facilitate the release of harmful materials from batteries to both the environment and the workers recycling batteries.
An electric vehicle battery is a rechargeable battery used to power the electric motors of a battery electric vehicle (BEV) or hybrid electric vehicle (HEV).
The lithium-titanate or lithium-titanium-oxide (LTO) battery is a type of rechargeable battery which has the advantage of being faster to charge than other lithium-ion batteries but the disadvantage is a much lower energy density.
An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode. The terminal marked negative is the source of electrons that will flow through an external electric circuit to the positive terminal. When a battery is connected to an external electric load, a redox reaction converts high-energy reactants to lower-energy products, and the free-energy difference is delivered to the external circuit as electrical energy. Historically the term "battery" specifically referred to a device composed of multiple cells; however, the usage has evolved to include devices composed of a single cell.
