Recently,A news from USA,about a new type lithium batteries with fluoride carbon.
The United States developed the lithium fluoride carbon batteries, according to foreign media reports, the department of energy's oak ridge national laboratory researchers developed a new type of battery, which is based on lithium fluoride carbon provided (CFx) manufacturing, chemical formula can provide wearable equipment and health care equipment with electric power run 10 years. At present the corresponding paper published last week in the journal of the American chemical society ".
According to the paper's first author Chengdu Liang said the CFx battery can do little such as COINS, can give assembly sensor low-power fitness tracker or wearable device power supply for several years. Wearable devices main transfer a small amount of information to users, do not need to how much power, provided could be extended by CFx service life of the battery. "But the battery can't charge, it is disposable batteries", Chengdu Liang said.
Liang said: "this is a proof of concept study, but there is a private company is interested in the commercialization of the battery, have already get in touch with us. In the next few years, the concept of batteries may become a reality, depends on its commercialization process."
However, to be sure CFx battery is not new. Contour Energy companies have been provided to sell based on CFx chemical formula of special battery, used for army for unmanned aerial vehicle (uav), night-vision goggles and other electronic equipment, at the same time, the battery can have different size.
According to the U.S. army's existing study CFx chemical formula "known relative to other popular lithium battery chemistry, theory is one of the highest energy capacity of the chemical formula." Liang said: "this battery based on the theory of old but the design is new. This is a big breakthrough."
In the experiments, researchers at oak ridge national laboratory development, test, provided a real CFx battery, solid electrolyte is used to increase the battery energy capacity. The existing lithium-ion batteries use the positive form of positive and negative cathode electrode, rechargeable lithium ion can move in the electrolyte between them. When charging, lithium ion from cathode to anode storage. At the time of discharge, lithium ion from anode to cathode, and to the power supply equipment.
Provided new CFx has in the design of battery can be a solid lithium ion conductor and cathode thiophosphate multi-purpose electrolyte. Electrolyte can carry storage charge, help to increase energy capacity of the battery. Provided Liang said, CFx prototypes using solid electrolyte batteries, batteries using liquid electrolyte.
Liang said the double function of electrolyte can lead to a new battery design. New batteries may be marketed in the next few years. But he is not sure make the cost of the battery. "I don't know batch production and the cost of each battery. All materials we used here is enough."
Finally, Liang also said that the oak ridge national laboratory researchers on this battery technology spent three or four years, is currently studying the new solid electrolyte materials.
In addition,Kingwell Energy Co.,LTD from China supplys long life ordinary lithium battery,such as lithium priamry battery,lithium rechargeable battery and so on.
