The price of lithium battery raw materials has doubled. The reason behind this price doubling is that the new energy vehicle market continues to be hot, which has generated a large number of orders to upstream electric and lithium battery factories. product factories.Raw materials of lithium batteries for new energy vehicles are also rising. Driven by various favorable policies, new energy vehicle manufacturers are making great efforts, and the global market is ushering in a new round of development opportunities, which has also led to a continuous rise in battery raw material prices in China. lithium such as lithium carbonate.
Attracting the attention of authoritative media:On April 30, even CCTV Finance began to pay attention to the rising prices of lithium and lithium battery raw materials. The rise in morning pricesThe early era of lithium batteries has attracted more and more attention. According to reports, currently, the price of battery-grade lithium carbonate has more than doubled from last year's low of 38,000 yuan per ton to 90,000 yuan per ton; lithium hydroxide rose from 60,000 yuan per ton to more than 80,000 yuan per ton. .
Lithium-ion battery classification:According to different classification standards, they can be divided into different types. According to the material of the negative electrode, they can be divided into lithium cobalt oxide batteries, lithium iron phosphate batteries and. ternary batteries; according to the shape of the product, there are square batteries, cylindrical batteries and soft batteries according to the application scenarios, they can be divided into consumer electronics, energy storage and power batteries; Among them, consumer lithium batteries aret mainly used in 3C products; energy storage batteries are mainly used in household energy storage and distributed independent energy systems such as solar and wind power generation are mainly used in various electric vehicles, power tools and new; energy vehicles.
Usage:Lithium batteries are used in 3C, electric power, energy storage and other fields. Guohai Securities estimates that the global demand for lithium batteries will be 1,202 GWh in 2025, and the corresponding demand for electrolytes will be 1.32 million tons. However, due to the continued downward trend in prices of electrolytic products and the overall reduction in capital expenditure in the industry, only a few leading companies such as Tianci Materials will deploy new production capacitiesover the next few years, and the supply is relatively rigid.
From a global perspective, China is the largest consumer of lithium, with lithium demand accounting for 57% of the global total in 2019. And 60% of the demand comes from lithium batteries. In recent years, the importance of new energy vehicles has become more and more important. As the "core" of new energy vehicles, the importance of lithium batteries cannot be ignored. With the increasing certainty and rapid increase in the penetration rate of the new energy automobile industry, the market size of lithium batteries as the main energy source is also constantly expanding. In China, thanks to policy support and technological development, the sales volume of new energy vehicles in China has reached more than 1.2 million units, and the installed capacity of power batteries has reached more than 60 GWh.
Conclusion:According to some experts' analysis, lithium product companies are increasing their investment in production capacity. It is expected that the relationship between supply and demand will improve in the second half of the year, and the price of lithium products will fall back to a reasonable range of 50,000-80,000 yuan/ton.
The advantages of lithium titanate batteries are good safety and stability, fast charging performance, long life and good temperature resistance . The disadvantage of lithium titanate batteries is. energy density. Low, the price is high.
1. Advantages of lithium titanate battery:
1. Good safety and stability: traditional. Once the carbon electrode is overcharged after incorporating lithium, the metal lithium will easily precipitate on the surface of the electroof and flammable gas will appear when it comes into contact with the electrolyte, posing safety hazards. The electric potential of lithium titanate is higher than that of pure lithium metal, and lithium dendrites are less likely to appear. The discharge voltage is stable, and therefore the safety performance of lithium-ion batteries is improved.
2. Fast charging performance: Compared with carbon negative electrode materials, lithium titanate batteries have a higher lithium ion diffusion coefficient and can be charged and discharged at high speeds.
3. Long service life: Compared with current lithium iron phosphate batteries which can be used for up to 5 years with slow charging and 2 years with fast charging, lithium titanate batteries have very remarkable advantages.
4. Good resistance to temperature: the spinel structure of thelithium ion titanate battery has a three-dimensional lithium ion diffusion channel, so the performance of the lithium ion titanate battery at high and low temperatures is also very good. Titanate Lithium-ion batteries have good high temperature resistance and strong durability. They can be charged and discharged normally from minus 50℃ to above zero 60℃.
2. Disadvantages of lithium titanate batteries:
1. Low energy density: Compared to other types of lithium-ion batteries, the energy density is lower.
2. The price is high: Compared to other types of lithium-ion batteries, the price is high.
Technical characteristics of lithium titanate batteries
During the process of intercalation and extraction of lithium ions, the crystal structure of LTO remains very stable and does not change Volume, thus avoiding the formation of dendritesand electrode damage, and improving safety and battery life. The operating potential of LTO is 1.55V, which is much higher than the 0.1V of graphite electrodes, which can reduce the precipitation of lithium metal and reduce the risk of thermal runaway.
LTO also has a three-dimensional lithium-ion channel, which makes the diffusion speed of lithium ions fast and the internal resistance of the battery low. It can realize rapid charging and discharging of large current and improve power. battery charging density and efficiency. LTO also has good low temperature resistance and can operate normally below -30°C, making it suitable for applications in cold areas.
