The first charge of lithium battery

Charginglithium ion batteryfor the first time to the question seems to be a lot of people; this requires clear following common sense. Firstly, and full can: lithium battery first times using not exists "activated" problem, reasons is: lithium battery and nickel hydrogen battery of charging and discharging characteristics has very big of difference, more deep of reasons also is, had filling will on lithium battery especially liquid lithium ion battery caused great of hurt, thus, charging should by standard time and standard method charging, do don't for super long charging. The right way is: lithium battery stops immediately after separation of lithium-ion batteries and chargers. Lithium-ion batteries in a (temporary) will stop automatically after charging, do not exist "sustained" long trickle charging, which is the difference of lithium-ion batteries and nickel-metal hydroxide batteries. Charger full indicates lamp bright if not immediately removed words, due t…

Influence factors and optimization of dispersion of lithium-ion batteries

Lithium batteryin into group process in the, due to lithium core itself constitute material of subtle differences and into group process of level different, will makes lithium core in using and placed process in the appeared function performance inconsistent of phenomenon, this is lithium battery of discrete phenomenon, description this discrete phenomenon of quantitative index is discrete degrees, it is by several parameter of function relationship obtained of, caused discrete degrees numerical changes of main has: resistance, and voltage, and capacity, and temperature,. 1.Battery internal resistance, especially the polarization resistance of inconsistency that individual cell voltage during the charge/discharge process changes rapidly, resulting in a change of the entire battery pack;2.Inconsistencies, battery voltage will affect the peak capacity of the battery pack, giving the whole battery pack release energy;3.Have radiated heat, because batteries work process, the battery temper…

Requirements for different uses lithium battery research and development

Lithium battery is the main market is portable device applications, which makes high capacity lithium-ion battery development direction, but in the context of full electric vehicles and large power storage device development, lithium-ion batteries the main direction of research and development trend of diversification have also appeared. Traditional market of mobile terminals, such as cell phones and notebook computers require high volume, because they often entail a charge can be used for a long time. Popular of iPhone and iPad once a charge was used not long after consumer criticism, therefore, when the new iPad published, the original 6500mAh lithium battery is changed to use 14000mAh large-capacity lithium ion battery. This thing can be seen as a development of rechargeable batteries for portable terminal with high capacity for proof of the direction, to do this, even at the expense of life to realize higher capacity, and general requirements for life is 2 years. However, after the …
