What is Lithium ion Battery?
this is an old question. you may find a lot of answers on website. here SINOLI Battery is to classify it in brief way with two pionts with picture for your review.
Lithium ion battery is a very wild and extensive topic to discuss.
you can divide it into recharge or non-rechargeable battery, you can divide it with anode electrode chemistry characteristic, you can divide it as per it's power charge and discharge performance, you can divide it as per it's shape, you can also divice it as per it's working platform etc.
mostly, you will find as per it's application, for example, the battery is used in solar system, you might understand it as solar battery, but not all so called "solar battery" is a same thing. each battery has it's unique electrical performance, which is used with different intensions and function differs a lot as per it's intension application requirement.
this is information explosion era, you can search a lot articles and thesis to read. but it will definitely cost a lot of time to read and understand how does this works and how does that works. take lithium ion battery for example, one project need you to have very good price on high quality robot system, which needs metals casing, shaping, screws, electric circuit management board, portable power supply charge in short time and once charged you can use for a long time. therefore, you have options with all kinds of rechargeable batteries, but lithium ion battery is the best option. why?
because after full understanding of all kinds of recharageable batteries from past to currently leading tech. Lithium ion battery, especially NCM is still a leading contendor for most automotive applications.
in wekipeadia, it narrate as below:
Handheld electronics mostly use LIBs based on lithium cobalt oxide (LiCoO2), which offers high energy density but presents safety risks, especially when damaged.
Lithium iron phosphate (LiFePO4), lithium ion manganese oxide battery (LiMn2O4, Li2MnO3, or LMO), and lithium nickel manganese cobalt oxide (LiNiMnCoO2 or NMC) offer lower energy density but longer lives and less likelihood of unfortunate events in real-world use (e.g., fire, explosion, etc.). Such batteries are widely used for electric tools, medical equipment, and other roles. NMC in particular is a leading contender for automotive applications.
Future Lithium Battery:
Lithium nickel cobalt aluminum oxide (LiNiCoAlO2 or NCA) and lithium titanate (Li4Ti5O12 or LTO) are specialty designs aimed at particular niche roles. The newer lithium–sulfur batteries promise the highest performance-to-weight ratio. Lithium Graphene Battery etc.
even though, all kinds of prevailing material or techolody has it's advantages and disadvantages. the future Lithium ion battery is still under research. some is successed in research stage but not commercialized yet. each new technique improvement will cover the short comings of the previouse/traditional inventions, so that the society will keep going and advancing. hope the life for our children and our children's kid is much better and better.
