Lithium-ion Battery / Li-ion Battery
A lithium-ion (Li-ion) battery is an advanced battery technology that uses lithium ions as a key component of its electrochemistry. During a discharge cycle, lithium atoms in the anode are ionized and separated from their electrons. The lithium ions move from the anode and pass through the electrolyte until they reach the cathode, where they recombine with their electrons and electrically neutralize. The lithium ions are small enough to be able to move through a micro-permeable separator between the anode and cathode. In part because of lithium's small size (third only to hydrogen and helium), Li-ion batteries are capable of having a very high voltage and charge storage per unit mass and unit volume.
Li-ion batteries can use a number of different materials as electrodes. The most common combination is that of lithium cobalt oxide (cathode) and graphite (anode), which is most commonly found in portable electronic devices such as cellphones and laptops. Other cathode materials include lithium manganese oxide (used in hybrid electric and electric automobiles) and lithium iron phosphate (LFP). Li-ion batteries typically use ether (a class of organic compounds) as an electrolyte.
Lithium-ion batteries, while first commercially developed for portable electronics are now ubiquitous in daily life, in increasingly diverse applications including electric cars, power tools, medical devices, smart watches, drones, satellites, and utility-scale storage. As battery usage multiplies, so do the specific requirements, with increasing divergence of battery designs and sizes to suit each specific use. A pressing challenge, especially over the next decade, is to develop batteries that will make a significant contribution to reducing and eventually eliminating carbon emissions, in some countries as early as 2050, to mitigate global warming.
CETC manufactures and supplies high-quality lithium-ion battery cells and packs for installers and customers all over the world. All the batteries are subject to stringent quality controls throughout every step of the manufacturing and through to their final dispatch.
