Lithium battery cell is the smallest unit of lithium battery and one of the most important components of lithium battery. There are many kinds of lithium battery cells on the market, which ones do you know? Today, this article will introduce the types of lithium battery cells. Let's take a look together.
The positive electrode material has high working voltage (average working voltage is 3.7V), stable charge and discharge voltage, small size, high specific energy, good cycle performance, high electrical conductivity, simple production process and easy manufacture.
Main advantages: mature technology, wide application range and small size.
Main disadvantages: The cycle life is about 300 times, the safety performance is low, the resistance to overcharging is poor, it is not suitable for high-rate charging and discharging, and it will pollute the environment after disposal.
The difference between polymer cells and traditional lithium-ion batteries lies in the production process. Lithium batteries are wound and are soft in volume. The polymer is superimposed and the body is relatively rigid. For the same volume of polymer and lithium batteries, the capacity of the polymer is larger, about 30% higher. And safer, with less risk of explosion. long lasting. Charge and discharge reached more than 500 times.
The disadvantage is that the cost is high, and the polymer battery of the same capacity is at least 100% more expensive than the 18650 lithium-ion battery.
Lithium iron phosphate battery refers to a lithium ion battery using lithium iron phosphate as a positive electrode material. The positive electrode of lithium battery is lithium iron phosphate material, which has great advantages in safety performance and cycle life, which are also one of the most important technical indicators of power battery. The 1C charge-discharge cycle life can be achieved 2000 times, the puncture does not explode, and it is not easy to burn and explode when overcharged.
Main advantages: 2000 cycle life, high current charge and discharge, small internal resistance and less heat, safe, environmentally friendly and non-toxic.
The main disadvantages: the price is expensive, the digital product field has not been used on a large scale, and the awareness of consumers is low.
