The difference between lithium polymer battery and lithium ion batteries

Source: 2020 - 04 - 12 clicks mark: lithium battery profile 1. What is a lithium battery lithium batteries are widely used in various electronic devices: mobile phone, notebook computer, PDA, etc. Lithium battery is not special technology model plane. Lithium polymer battery and lithium ion batteries have one thing in common the same voltage 3. 6v。 Of course, there are differences. Lithium ion battery encapsulation in the metal shell, and lithium polymer battery encapsulation in the flexible packaging. Ordinary lithium polymer battery is by square wafer (with the positive and negative Figure 10. ) Made of. Its outstanding advantage is light weight, very suitable for aviation aircraft. 2. Voltage after a full battery and lithium battery number 4. 2 v, after the discharge voltage is 3. 0v。 No more than when using the two limits, otherwise it will cause damage to the battery. Avoid lithium battery voltage is lower than 3. 0 v of the specific method is to set the minimum voltage in the electronic governor. When a single battery voltage drop to 3. The manipulator is below 0 v, get feedback from the power suddenly fell, and know that it is time for the model of landing. If you have any automatic electronic governor lithium battery model, it can automatically determine the number of cells, and automatically set the voltage limit. 3. 10 what is c? What is 3 s4p? Battery discharge rate can be expressed in c, 1 c said battery run out in less than an hour, 2 c said half an hour. The reciprocal of the discharge time is c. The power of the battery is ma for the unit to measure. For a 2000 ma battery, if with the charging current of 2000 ma, an hour to finish charging. In the capacity of the battery, the number of C and a concise mathematical relationship between discharge current. A 2 000 milliampere batteries, if use 1 c discharge, the discharge current of 2 000 ma & times; 1=2A; If discharge for 3 c, the discharge current of 2 000 ma & times; 3=6A。 All batteries have a limited rate of discharge. In order to achieve this goal, often used at the same time a few piece of lithium batteries for high current. Described the positive electrode of the battery with the positive parallel described, referred to the cathode and the anode connection. If you connect two lithium batteries at the same time, you will get twice the current. Two 2000 milliampere lithium batteries in parallel is equivalent to a lithium battery, 4000 ma C number as well as the original, rated current is doubled. In other words, if the battery can discharge 5 and 10. A, c, parallel can discharge after 5 c and 20 a. Modelers often use this method to obtain the large discharge current. XSxP naming method clearly expressed the series-parallel cell number, S in front of the Numbers are series-parallel cell number, P before the number is the number of cells in parallel. 3 s4p, 2 100 mah lithium-ion batteries, contains 12 pieces of batteries. Assumes that the discharge rate is 6 c, the voltage is determined by the number of battery series 3, the discharge current is determined by the four the number of batteries in parallel. Therefore, the voltage of the battery to 10. 8v( 3× 3. 6v) , the maximum discharge current is 50. 4a ( 2 100mA× 6× 4) 。
