Development of new energy storage devices and key technologies - 602030 lipo battery
602030 lipo battery use carbon materials as the negative electrode and lithium-containing compounds as the positive electrode. There is no metallic lithium, only lithium ions. It is a secondary battery (rechargeable battery) that mainly relies on lithium ions to move between the positive electrode and the negative electrode. Come to work.
Core Tips 602030 lipo battery for New Energy Storage Devices (1)
602030 lipo battery use carbon materials as the negative electrode and lithium-containing compounds as the positive electrode. There is no metallic lithium, only lithium ions. It is a secondary battery (rechargeable battery). It mainly relies on lithium-ion battery ions in the positive and negative electrodes. Move between to work. During the charge and discharge process, Li+ intercalates and deintercalates back and forth between the two electrodes: during charging, Li+ deintercalates from the positive electrode and embeds into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; during discharge, the opposite is true. 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. The carbon used as the negative electrode has a layered structure with many micropores. The lithium ions that reach the negative electrode are embedded in the micropores of the carbon layer. The more lithium ions are embedded, the higher the charging capacity. Similarly, for 602030 lipo battery, when the battery is discharged (that is, the process when we use the battery), the lithium ions embedded in the carbon layer of the negative electrode are released and move back to the positive electrode. The more lithium ions returned to the positive electrode, the higher the discharge capacity.
602030 lipo battery have obvious advantages. They have high voltage. The working voltage of a single battery is as high as 3.7-3.8V; they have large energy, and the actual specific energy that can be achieved is about 555Wh/kg; they have a long cycle life, which can generally reach more than 500 times, or even 1,000 times. Above; good safety performance; small self-discharge, the self-discharge rate of fully charged Li-ion at room temperature is about 2% after one month of storage; it can be charged quickly. But unlike other rechargeable batteries, 602030 lipo battery lose capacity slowly.

Driven by the rapid growth of the global electric vehicle market, global 602030 lipo battery are growing rapidly. In 2018, the global lithium-ion battery industry reached US$41.2 billion, reaching 200GWh in terms of capacity. In 2018, my country's lithium-ion battery market was 170 billion yuan, power lithium batteries were 89 billion yuan, consumer batteries were 75 billion yuan, and energy storage batteries accounted for 3-4%. Starting from 2017, power lithium batteries have surpassed consumer batteries.
Regarding the power lithium-ion battery industry, global new energy vehicle sales in 2018 were 2.1 million, of which 69% were pure electric and 31% were plug-in hybrid. According to the "Medium and Long-term Development Plan for the Automobile Industry" jointly announced by the Ministry of Industry and Information Technology, the National Development and Reform Commission and the Ministry of Science and Technology in 2017, by 2020, the annual production and sales of new energy vehicles will reach 2 million units. In 2025, new energy vehicles will account for More than 20% of production and sales.
Core Tips New Energy Storage Devices: Lithium-Sulfur Batteries (1)
Lithium-sulfur battery is a type of lithium-ion battery, which uses sulfur element as the positive electrode and metallic lithium battery as the negative electrode. Lithium-sulfur batteries use sulfur as the positive electrode reaction material and lithium as the negative electrode. During discharge, the negative electrode reaction is that lithium loses electrons and becomes lithium ions. The positive electrode reaction is that sulfur reacts with lithium ions and electrons to form sulfide. The potential difference between the positive electrode and the negative electrode reaction is the discharge voltage supplied by the lithium-sulfur battery. Under the action of external voltage, the positive and negative electrode reactions of lithium-sulfur batteries proceed in reverse direction, which is the charging process. Elemental sulfur is abundant in the earth and has the characteristics of low price and environmental friendliness. In addition to very high energy density, lithium-sulfur batteries have relatively low production costs, low toxicity after use, basically no pollution to the environment, and low energy consumption for recycling. They are a very promising lithium-ion battery. But the biggest disadvantage is that its recycling times are relatively low, which greatly increases the cost of using lithium-sulfur batteries.
Foreign lithium-sulfur batteries were developed earlier and are in the early stages of industrialization. The lithium-sulfur battery developed and produced by SionPower Company in the United States in 2016 has a 20Ah, 400Wh/kg, and 350 cycles at 1C; the lithium-sulfur battery developed and produced by OXIS in the United Kingdom in 2018 has an energy density of 425-500Wh/kg and is cycled less than 100 times.
