What are the advantages and disadvantages of lithium titanate batteries?lithium trolling motor battery manufacture

　　Lithium titanate is as high as 1.55V as the negative electrode material, which is more than 1V higher than the traditional graphite negative material. Although it loses some energy density, it also means that the battery is safer. Technical expert Lu Languang once said that the demand for negative electrode voltage when the battery is quickly charged, but if it is too low, the lithium battery is easy to precipitate very lively metal lithium. This lithium ion not only conductors, but also respond to the electrolyte. Then Release the heat, produce flaxed gas, and cause fire. The lithium titanium titanate avoids the situation of 0 negative electrode voltage because the high 1V voltage is 0, which indirectly avoids the precipitation of lithium ions, thereby ensuring the safety of the battery.

　　Because lithium titanate batteries can achieve safe use in high temperature and low temperature environment, it also reflects its important advantages of its wide temperature (especially low temperature resistance). At present, the safety working temperature area of Yinlong titanate batteries is between -50 degrees and 65 degrees, while ordinary graphite negative batteries begin to decay when the temperature is lower than -20 degrees.

　　-30 degrees charging capacity is only 14%of the total charging capacity, and it is impossible to work properly in severe cold weather. In addition, because lithium titanate batteries are over -charged, they only have a volume change of 1%, which is called zero -changing material, which makes it a long life. Wei Yincang, chairman of Yinlong, said that the life of Yinlong's lithium titanate battery can reach 30 years, which is equivalent to the service life of the car, while the average life of the battery of ordinary graphite negative materials is only 3-4 years.

　　The last advantage of lithium titanate is that it has a strong rapid charging and discharge capacity and a high charging rate. At present, the charging rate of lithium titanate batteries is 10c, or even 20C, while the battery charging rate of ordinary graphite negative materials is only 2c-4C. Based on these technical characteristics of lithium titanate batteries, industry insiders believe that it meets the needs of new energy buses and large energy storage equipment. Take a bus, and generally do not exceed 4 kilometers for a single mileage. Entering the station at the end of each time will take at least a few minutes to the next departure time. At this time, the disadvantage of low energy density of lithium titanate batteries will not affect the use of passenger cars, but it reflects the benefits of battery fast charging. As a public transportation, buses have put forward higher requirements for the safety and durability of batteries.
