Speak the classification and composition of the electrolyte, and how to choose the battery pack correctly

　　The electrolytes of lithium batteries can be divided into ordinary electrolytes, high temperature electrolytes, low -temperature electrolytes, speed electrolytes and dynamic electrolytes according to their application fields. The liquid electrolyte and solid electrolytes are different according to their electrolytes. The industry is more common in industries to divide according to electrolytes. At present, most of them use liquid electrolytes.

　　Common lithium -ion battery electrolytes are generally composed of organic solvents and electrolyte (lithium salt). Lithium -ion batteries need solvents such as safety, stability of oxidation, compatibility with negative electrodes, and conductivity. In general, solvents must have high dielectric constant and lower viscosity.

　　Many times, when we choose a battery, we will consider whether the category characteristics of the battery are applicable to our device, so let's talk about how to choose the appropriate battery pack for the device today.

　　First of all, you must understand your device, and you need to understand the following issues:

　　1. What is the input voltage of the device? What is the power consumption (Wat number)? What is the maximum current consumption (A)? What is the expected working time of the battery pack?

　　2. Determine the battery voltage you want to choose. The battery voltage must be or slightly higher than the requirements of the device

　　3. If you need a precise voltage and the battery pack cannot be provided, you can consider using the regulator.

　　How to calculate the battery pack capacity (MAH or AH)?

　　The battery capacity depends on the time (hours) required for the operation equipment. It can be calculated based on this formula: (AH) = device power (W) x running time (hour)/battery voltage (V). For example, if you use 12V battery packs and run 10W equipment for 10 hours, the result is (10 × 10)/ 12 = 8.3, you need to choose a battery pack with a capacity> 8.3AH. 1000 mAh = 1AH, higher MAH will provide longer running time.
