Principles of lithium ion batteries

Lithium battery, lithium ion battery, lithium polymer battery, people often are these "lithium-ion" battery is not identified, the principle of lithium-ion batteries are necessary into the key to solve this puzzle, because all those involved "lithium-ion" battery theory, principle of lithium-ion batteries is a line through the bonds of the three, has an important role. First, we initially proposed three concepts. In the history of lithium-ion batteries, the first stage is the lithium-ion battery, the battery's anode is lithium metal, on the basis of this, the second phase development out of the rechargeable lithium-ion battery, a theory in which the lithium ion battery, rechargeable lithium-ion batteries are not lithium, lithium-ion batteries only. Because as the electrolyte and cathode material of lithium-containing compounds are different, thus, it is based on the principle of different materials of lithium-ion batteries. In recent years, people often said ofl…

Lithium battery self-discharge

Lithium battery self-discharge is a battery voltage drop in the circuit can be replaced, in ternary lithium, lithium cobalt oxide, manganese oxide material electrode, lithium battery self-discharge phenomenon was inevitable. Lithium-ion battery self-discharge capacity loss according to whether or not reversible is divided into two: the capacity loss reversible refers to the second battery capacity can be restored; irreversible capacity loss, capacity cannot be recovered. The factors affecting the level of self-discharge: cathode and cell preparation process, nature and concentration of the electrolyte, the battery storage temperature and storage time, among them, the temperature dependence is relatively large. Lithium-ion batteries self-discharge, loss of capacity and much of it can be recovered, following a case of lithium manganese oxide to analyze the reasons behind this phenomenon. Speaking from the mechanism, fully charged lithium ion battery self-discharge is due to the decompositi…

The difference between lithium-ion battery chargers and adapters

According to Baidu encyclopedia interpretation: the adapter is English Adapter Chinese translation, transfer adapter is an interface, or an adapter. Using the adapter is the role of the regulator, in other words, AC / DC power stability into electrical equipment, during which there is no storage of electricity, once the AC / DC adapter cannot give electric power equipment; secondly lithium ion battery adapter is as a built-in power supplies or external power supply. Adapter is a hardware independent interface device, can also be a messaging interface. Usually adapter power adapter, USB and serial switching equipment, etc. The main function of the adapter is a voltage regulator, generally consists of a housing, power transformer and rectifier circuits. Suitable for small, portable electronic devices and electronic power conversion equipment. It is ancillary equipment, are widely used in machine tools, game machine, language repeater, and so on. Baidu encyclopedia interpretation of the cha…

Industrialization of large lithium-ion batteries needed markets, capital and technology matures

Since the birth of the first battery, battery applications more and more widely, from small electronic products to large, larger areas of application development. Current major applications focused on electric vehicles, the future might be on the energy storage power station, batteries used in electric vehicles and energy storage power station is a energy power battery, battery category lead-acid batteries, nickel-metal hydroxide batteries and lithium ion batteries. Lead-acid batteries are mainly used in the car boot and regular power supply, but the trend of the secondary battery has been replaced, nickel hydrogen battery power and self discharge rate and memory effects and other shortcomings in the performance, which is certainly a transitional product, this transitional period may only 10 Years, and trends are becoming evident. Lithium-ion batteries are the latest new energy vehicle power supply, it was originally applied to small electrical appliances, at present, mobile phone and n…

Lithium polymer battery use and Assembly considerations

Lithium polymer battery is a electrolytic quality for gel rubber-like, and packaging soft of lithium battery, in civilian market often was called soft package lithium battery, this makes lithium battery electric core has and General liquid lithium ion battery not as of place, thus some special of note matters, following on electric core in using and assembled process in the may appeared of not right practices proposed following note matters. First, in the use of batteries, including on aluminum-plastic composite films, top edge (end edge), lateral edge, its protection and measures to avoid mechanical impact, short circuit. 1 Aluminum-plastic laminated film packaging protection: mainly to avoid being stabbed sharp parts are damaged. To this end, should often clean batteries around the environment, contact against sharp parts or bump the batteries, take time to wear gloves, avoid fingernails scratching the surface. 2 The top edge and side edge protection: to avoid damage to edges and side …
