Lithium ion battery is a secondary battery (charging battery), which mainly relies on lithium ions to move between positive and negative electrodes. In the process of charging and discharge, Li+ is embedded and dehydrated between the two electrodes: when charging, li+ is removed from the positive pole, the electrolyte is embedded in the negative electrode, and the negative electrode is in the lithium rich state; the opposite is opposite during discharge.
The electrode materials are all lithium ions that can be embedded (inserted)/dehydrated (off).
Dynamic batteries with lithium cobaltate, lithium manganate, nickel cobalt lithium manganate (ternary material), lithium iron phosphate, etc. are the power batteries of positive electrode materials. Development trends; like all chemical batteries, lithium -ion batteries are also composed of four parts: positive, negative, septum and electrolytes.
Positive -active substances are generally lithium cobaltate, lithium manganate, nickel cobalt lithium manganate (ternary material), lithium iron phosphate material, etc.
Positive reaction: Lithium ions are embedded during discharge, and lithium ions are removed when charging.
Lithium cobaltate battery:
Its characteristics are stable structure, high capacity ratio, outstanding comprehensive performance, but poor safety, and very high costs. They are mainly small and medium -sized battles. They are widely used in small electronic devices such as laptops, mobile phones, MP3/4 V.
Lithium manganate battery:
Lithium manganate is a positive electrode material with low cost, safety and low temperature performance, but its material itself is not very stable, and it is easy to decompose to produce gas. Therefore, it is mostly used to mix it with other materials to reduce the cost of the battery cell. Fast attenuation, swelling, poor high temperature performance, and relatively short life. It is mainly used for large and medium -sized battery cells and power batteries. The parameters are as follows:
The nominal voltage is 3.7V, the output voltage range: 2.5 ~ 4.2V, the standard continuous discharge current: 0.2C, maximum continuous discharge current: 1C, operating temperature: charging: 0 ~ 45 ℃, discharge: -20 ~ 60 ℃.
