A Lithium-ion Battery
Lithium-ion custom battery packs are a reliable and valuable power source. Similar to the way that lithium-ion batteries are used on computers, they are used in a variety of applications such as electric bikes, mobile phones and laptops. These batteries can be configured to suit the needs of your application: size, shape, voltage and amperage.
WHAT IS A LI-ION BATTERY?
A lithium-ion battery (abbreviated as Li-ion or LIB) is a type of rechargeable battery in which lithium ions move from one electrode to an opposing electrode during discharge and back when charging. Lithium-ion batteries are common in consumer electronics such as mobile phones, laptop computers, digital cameras, power tools and electric cars.
THE IMPLEMENTATION OF LI-ION BATTERIES
Sony and Asahi Kasei release the first lithium-ion battery for commercial use in 1991.
As positive electrode materials, lithium iron phosphate (LiFePO4) and other phospho-olivines (lithium metal phosphates having the same structure as mineral olivine) were proposed in 1996 by John Goodenough, Akshaya Padhi, and colleagues.
2001: Zhonghua Lu and Jeff Dahn submit a patent for the lithium nickel manganese cobalt oxide (NMC) class of positive electrode materials, which offers improved safety and energy density over the commonly utilized lithium cobalt oxide.
Yet-Ming Chiang and his team at MIT demonstrated a significant improvement in the performance of lithium batteries in 2002 by doping the material with aluminum, niobium, and zirconium to increase its conductivity. The precise mechanism responsible for the growth became the subject of extensive discussion.
Using lithium iron(II)phosphate particles with a diameter of less than 100 nanometers, Chiang boosted performance once more in 2004. This nearly one hundredfold decreased particle density, increased the positive electrode’s surface area, and enhanced capacity and performance. Commercialization led to a quick expansion of the market for LIBs with more storage capacity, as well as a dispute between Chiang and John Goodenough over patent infringement.
In Japan, lithium-ion batteries accounted for 66% of all secondary (rechargeable) portable battery sales in 2011.
John Goodenough, Rachid Yazami, and Akira Yoshino were awarded the 2012 IEEE Medal for Environmental and Safety Technologies for their contributions to the development of the lithium ion battery.
2014 – Amprius Corporation commercial batteries with a silicon anode surpassed 650 Wh/L (a 20% increase) and were delivered to customers. John Goodenough, Yoshio Nishi, Rachid Yazami, and Akira Yoshino were honoured by the National Academy of Engineering for their pioneering work in the discipline.
As of 2016, the global production capacity for lithium-ion batteries was 28 gigawatt-hours, including 16.4 GWh in China.
BATTERY CLASSIFICATION FOR LI-ION
SHAPE-BASED LI-ION BATTERY CLASSIFICATION
Numerous varieties additionally feature an inbuilt protective circuit that prevents over-discharge and short-circuit damage. This can extend their physical length; for example, an 18650 is around 65 mm (2.56 in) long, but with an inbuilt protection circuit, it may be approximately 68 mm (2.68 in) long. Safe and economical recharging of these cells requires a charger designed for them.
Similar to the scheme used for lithium button primary cells, commonly used identification numbers represent the physical dimensions of the cylindrical cell. The first two figures represent the (approximate) diameter in millimeters, followed by the last three digits representing the (approximate) height in tenths of millimeters.
Applications for Li-ion batteries
Lighting(emergency lighting, industrial lighting, outdoor lamps and lanterns, miner’s lamp), Surveying and Mapping Instruments(total station, detector), RFID Products(barcode scanners, handheld printers, POS machine), Consumer Electronics(electric tools, toys, electronic cigarettes, model aircraft, unmanned aerial vehicles (uavs), medical equipment, AGV robot, auto stop power supply), and others.
