3.7v 350mah li polymer battery Manufacturers

1. The 18650 battery is cylindrical with transparent liquid inside. This is due to the battery concept and material. 18650 is suitable for high current, so that almost all laptops and electric cars are basically designed with 18650 batteries; only super notebooks, This is due to environmental protection and energy saving, so polymer lithium-ion batteries can be used instead of 18650 batteries, especially for tablet computers, etc. Digital cameras are due to the large voltage and instantaneous high current required for charging and discharging of the photo flash, so only 18650 can be used. Similar batteries, only slightly smaller;

In terms of materials used, the positive electrode materials of polymer lithium ion batteries are divided into lithium cobalt oxide, lithium manganate, ternary materials and lithium iron phosphate materials. The negative electrode is graphite, and the working principle of the battery is basically the same. The important difference between the positive electrode materials of polymer lithium ion batteries lies in the difference of electrolytes. Liquid lithium ion batteries use liquid electrolytes, and polymer lithium ion batteries use solid polymer electrolytes instead. This polymer can be dry or glued. At present, most of the polymer gel electrolytes are used.

In addition to the power lithium battery function, the launching type of iron phosphate battery also has an instantaneous high -power output function. It uses electric power lithium batteries with less than 1 degree instead of traditional lead -acid batteries. It has idle start stopping function, and also has engine shutdown, taxiing and braking energy recycling, accelerated assistance and electric cruise functions.

Differences between lithium battery and lithium-ion battery

Electric cell refers to a single electrochemical cell containing positive and negative electrodes, which is not used directly. It is different from the battery which contains protective circuit and housing, and can be used directly. Generally speaking, it is a battery that removes the shell, and the rest is called the battery cell.
