What does 9990vf lithium battery mean?

The 9990VF lithium battery is a lithium-ion battery model, where "9990" represents the capacity of the battery and "VF" represents the structure and purpose of the battery.

In "9990", "99" means that the nominal voltage of the battery is 3.7 V (the actual voltage is generally between 3.6 and 3.8 V), and "90 » means the battery capacity is 9000 mAh. (mAh). Ampere-hour), which is the amount of charge the battery can provide during the discharging process. The total energy of this lithium battery is therefore 3.7 V x 9 Ah = 33.3 Wh.

The meaning of “VF” is relatively diverse and can vary between brands and manufacturers. Generally speaking, the "V" indicates that the battery is a rechargeable lithium-ion battery, while the "F" may refer to characteristics such as the shape or size of the battery. For example, some manufacturers interpret “F” as “ Flat”, indicating that the shape of the battery is flat, but not all manufacturers do this. In addition, “VF” can also represent other characteristics such as the application area and usage environment of the battery.

It should be noted that when using or selecting lithium-ion batteries, they should be selected according to specific application scenarios and requirements to ensure that the battery can meet the required voltage, capacity, size and safety. requirements. Different models of lithium batteries may have differences in actual use, so you should carefully study their specifications and parameters when choosing.

42vf lithium battery means that the lithium battery is 42v, which means that a 42v battery can be used, or it can be regarded as a v model represents the voltage unit,volt , 42 V represents the voltage intensity and refers to the lithium battery providing 42 volts. The experiment used a square lithium iron phosphate battery with a capacity nominal capacity of 86 Ah produced by CATL.

The battery uses LiFePO4 as the positive electrode material, graphite as the negative electrode material, uses polyethylene separator and LiPF6 electrolyte, and selects 20 batteries from the same batch with similar electrical properties for the storage in order to test the electrical properties. batteries.

Advantages of Lithium Batteries

Lithium batteries have a high voltage platform. The average voltage of a single battery is 3.7V or 3.2V, which is approx. equal to 3 nickel-cadmium batteries or the series voltage of nickel-metal hydride batteries to facilitate the formation of power packs.

Compared to batteries, batterieslithium have a high energy density. It has a high storage energy density, currently reaching 460-600 Wh/kg, approximately 6-7 times that of lead-acid batteries.

Compared to lead-acid batteries, lithium batteries are lightweight, weighing about 1/5 to 6 that of lead-acid products for the same volume.

Lithium batteries have a relatively long service life, and the service life can reach more than 6 years. Lithium iron phosphate batteries because the positive electrode can be charged and discharged with 1 CDOD, and there are records that show this. they can be used 1,000 times.
