  To understand the difference in 36V lithium battery prices, we must first know how 36V lithium batteries are produced. Let's understand the price of 36v lithium battery from the perspective of 36v lithium production and manufacturing.

  How is 36v lithium battery produced:

  In fact, if you are a battery producer, for the efficiency of lithium batteries, the larger the size, the better. On the contrary, to a certain extent, the appropriate size is more beneficial to the performance of the battery. Therefore, in the battery production industry, the word battery is often used. In fact, batteries are also batteries. If you want to know more, you can Baidu.

  Generally speaking, the voltage of a polymer lithium battery cell is 3.2V to 4.2V. This is relatively common. There is also a small-volume lithium battery, such as an electronic watch. The voltage may be 1.2V to 3.0V.

  Then the 36V lithium battery will have the following combinations:

  1. Single-row series connection: If the voltage of a cell is 3.6V, then ten cells are connected in series. The price is: the number of cells multiplied by the unit price of the cell plus the processing cost plus a certain profit margin.

  2. Parallel and series: This calculation is also the same, the difference is that this method is to increase the capacity, the number of batteries required is basically doubled, so the price will be more expensive.

  Therefore, when purchasing a 36V lithium battery, you must first understand your actual equipment usage, and then screen and choose a battery with better economic benefits.

  Reasons for low capacity of lithium polymer battery:

  a. The amount of attached material is too small; b. The amount of attached material on both sides of the pole piece is quite different; C. The pole piece is broken; d. The electrolyte is less; e. The electrolyte conductivity is low; f. The positive and negative electrodes are not matched G. Diaphragm porosity is small; h. Adhesive is aging and the attached material falls off; i. The core is too thick (not dried or the electrolyte is not penetrated) j. The volume is not fully charged when the volume is divided; k. The specific capacity of the positive and negative materials small.

  Reasons for the high internal resistance of lithium polymer batteries:

  a. The negative electrode piece and the electrode lug are welded; b. The positive electrode piece and the electrode lug are welded; C. The positive electrode lug and the cap are welded; d. The negative electrode lug and the shell are welded; e. The rivet and the pressure plate contact with a large internal resistance f. No conductive agent is added; g. There is no lithium salt in the electrolyte; h. The battery has been short-circuited; i. The porosity of the diaphragm paper is small.
