Lithium batteries from time to tome what requirements?

Source: 2020 - 04 - 19 then clicks: first lithium battery is lithium battery manufacturer for battery performance test of one of the common tasks. First take a look at the battery voltage is low or the product standard parameters, and lithium ion battery performance test means of a small, almost all of the lithium battery manufacturers lithium battery factory battery or lithium battery discharge test, lithium battery e-test ability, over current testing, and so on, if don't do this kind of lithium battery factory shipment of lithium battery charging and discharging test, so you can see it as a 'dirty' manufacturer or a substandard lithium battery manufacturer, so maybe you will know more about the importance of lithium battery charge and discharge test. A lithium battery voltage, lithium battery charging rate shows that number of lithium battery and attenuation relationship include: 1. Lithium battery charge and discharge rate, the higher the better. 'C' description of battery charging and discharging current special symbols. 1 c discharge is refers to the battery in the space of an hour from full to empty the current. 2, multiplier example: iPhone6s battery capacity is 1810 mah, so the battery 1 c discharge current is 1. 81 amperes. For example, if the e6 electric cars using each of the battery capacity is 200 ah, is this battery 1 c discharge current for 200 amperes. If the battery at a high rate discharge, it usually release less energy than with a low rate of discharge. 4. Lithium-ion batteries are widely used in mobile phones and digital products, tablet computers and laptops, electric tools, electric bicycles, electric cars, after the power and energy storage, and other fields. Second, the lithium battery charge and discharge cycle time 1. The cycle of lithium-ion batteries is more, the better. 500 times is the common value of lithium-ion batteries, lithium battery charge and discharge times according to different materials ranging from 300 to 3000. This value in each specific meaning of the factory may be slightly different, can be roughly interpreted as: factory provisions of charging and discharging rate ( Such as after a 500 - cycle, only 80% of the original capacity battery) 。 If anode block battery and lithium battery cathode plate is good, battery fluid injection rate process, such as temperature control and work steps will achieve the technical standards, and then the battery failure rate is low, and relative to the quality of the batch of battery must be no problem, battery charging and discharging frequency quality and habits is too big, for example, is as follows: 2. The influence of the charge and discharge intensity of lithium battery cycles lithium battery manufacturer tip: per charge from 0% to 100%, 1 c charging, 0. 3 c charging, capacity attenuation to 80% after 500 times, this is the most rigorous testing cycle, can also be less strict, see below. If each charge cycle at 25% 75%, 1 c discharge and recharge 0. 3 c, capacity decreased to 80% after 2000 cycles. If each charge cycle at 25% Charging 75%, belong to the 3 c, 0. 3 c, after 1600 cycles, fell to 80% capacity. Lithium battery charging method 3. Light charging and discharging effect on lithium battery service life of the lithium battery manufacturer tip: per charge from 0% to 100%, 1 c charging, 0. 3 c charging, capacity attenuation to 80% after 500 times, is the most rigorous testing cycle, can also be less strict, see below. Electricity 25 per cycle Charging put 1 ℃, 75%, 0. 3 c, capacity attenuation to 80% after 2000 times. Each loop power in 50% Charging 100%, 1 c discharge, 0. 3 c, capacity attenuation to 80% after 1800 times.
