Almost all developing mobile electronic devices are more or less benefit from the rechargeable lithium-ion battery. Lithium is the lightest metal, this feature makes lithium compared with other metals, the same weight can hold more charge, thus greatly improving the performance of mobile phones, laptops, photo and other electronic devices, while also allowing electric vehicles R & D, and even small electric aircraft and other large equipment to become a reality. However, lithium-ion batteries are also inherent disadvantages: In some cases, when it is required to charge the external electronic monitoring equipment, otherwise cause excessive electrical charging overheat, causing damage, and even cause a fire; it discharges too quickly, affect electronic equipment standby time.

Although lithium-ion battery existence of such shortcomings, but in Vancouver, Canada, Corvus Energy company still believes that the lithium-ion battery stable enough, durable enough, now is the time to make larger lithium batteries, for tugs, cranes, large sailing powered machine. Corvus Company's interest in large-scale lithium especially deep. Just recently, the company has just won an order for a Chinese thermal power company tailored a capacity of 2200 kwh, equivalent to a tall container shipping lithium-ion batteries as backup power thermal power plants.

Large-scale manufacture of lithium batteries

Compared to the ordinary consumer goods, Corvus production of large lithium batteries are more durable, but their production principle is the same. Battery is great, but it is still a central part of the block by a single lithium composition. Like ordinary lithium batteries, lithium batteries used in large blocks of each small batteries have two electrodes, the electrodes separated by an electrolyte (usually a polymer composed of a gelatinous substance). When the battery is charged, lithium ions from the anode (made of metal lithium) to migrate to the cathode through the electrolyte (typically carbon). The opposite happens when the discharge, lithium ions from the cathode to swim back to the lithium anode carbon, this process will lead to the external circuit connected to the battery current is generated, power use.

The biggest difference with ordinary large lithium battery is different compared to its lithium anode production materials. Although the lithium ion battery anode is usually made of a lithium ion phosphate, but Corvus Company is another way, the use of a lithium nickel manganese cobalt (NMC) oxide to act as an anode, because the latter can provide a greater energy density, and therefore more suitable for large-scale lithium-ion battery. Perry said the company owner, NMC can provide electricity higher than 22% of metal phosphate, is a very good choice.

After a single lithium-ion battery ready, Corvus put them together to produce a standard of 6.2 kWh modules, which can be further assembled into electrical storage capacity of up to thousands of kWh large lithium ion battery. According to the company, the theory of large lithium-ion battery storage capacity limits can reach 40,000 kwh. As an example of this figure will be able to know more objective understanding: Nissan's new zero-emission electric vehicles hear the wind (Leaf) lithium battery capacity is only 24 kwh used. Such a large lithium enough horsepower to run up a car full for quite a while, but if it is used on a laptop, it is estimated forever without recharging. In addition, each standard module will be equipped with a unique electronic management system, in order to achieve its charge and discharge rate optimization. This produced a module may be implemented fully charged within 30 minutes, and in fact, the fastest rate of discharge, compared with only 6 minutes.

Recently, the British "Economist" magazine's technology section observed quarterly published an article, introduced in recent years, lithium-ion battery technology trends, said the lithium-ion battery will be getting bigger and bigger, and will be gradually replaced by other forms of The high-capacity battery, will expand its scope of application to virtually all industrial sectors. From now on, the lithium-ion battery applications will not be limited to small electronic devices, and the large industrial and renewable energy will also frequently appear in its presence.
