The cathode material of lithium ion batteries is lithium cobalt oxide, and the anode is carbon. The working principle of a lithium-ion battery refers to its charging and discharging principle. When the battery is charged, lithium ions are generated on the positive electrode of the battery, and the generated lithium ions move to the negative electrode through the electrolyte.
Lithium-ion battery lifespan will experience degradation during use, and the battery will become less and less durable. This is actually related to the cycle life and safety of the battery. Cycle life refers to the usable capacity of the battery. The undurable battery means that the storage capacity of the battery is decreasing. The reason is that the activated lithium ions in the battery are blocked and cannot be charged and discharged.
There are many types of lithium-ion batteries.According to different cathode materials, how many types of lithium batteries are there? It can be divided into lithium ferrite battery, cobalt acid lithium ion battery, manganese acid lithium ion battery, nickel acid lithium ion battery, ternary material lithium ion battery, iron phosphate lithium ion battery and so on.
Dongguan Power Long Battery Technology CO., Ltd. currently produces lithium iron phosphate lithium-ion power batteries with a cycle life of more than 8,000 times. The cycle life of the battery is also closely related to the temperature of the charge and discharge environment, the charge and discharge rate, and the depth of charge and discharge.
During the entire battery charging process, the lithium-containing compound of the positive electrode changes. Lithium loses an electron and becomes lithium ion (Li+), and the lithium ion is extracted from the positive electrode material. The electrolyte filled between the two poles acts as a traversing medium, allowing lithium ions to move from the positive electrode to the negative electrode, and finally be embedded in the negative electrode material at the other end of the battery.
At present, the more mature main energy storage batteries are: lead-carbon batteries, lithium batteries, flow batteries, sodium-sulfur batteries, and so on. Various battery technical characteristics have their own advantages, we briefly introduce the characteristics of various types of energy storage batteries.
Someone once vividly summarized the development road of China’s powerbatteries: the lithium batterywas invented by Americans, commercialized by Japanese and developed by the Koreans, our Chinese made it the cheapest and promoted to the world.China currently has two major industries that dominate the world, one is photovoltaic batteries and the other is power batteries.
