Looking at the current development status of the new energy industry, the technical level of power batteries is the key to the development of new energy vehicles. Its cost, technology, and manufacturing levels determine the cost, driving range, performance, and comfort of new energy vehicles.

　　Yinlong New Energy Chairman Wei Yincang delivered a keynote speech on "Innovation and Development of Power Batteries" at the "Battery Safety and Battery Modeling" seminar on April 18.

　　Five in one: Yinlong chooses reverse thinking

　　Wei Yincang said in his speech that the development of lithium batteries has evolved from a single pursuit of high energy density to the current balance of energy density, safety and operational efficiency. Although the national subsidy policy is biased towards energy density, the industry has experienced a change from high energy density. Although the density is gradually decreasing, although some lithium batteries have the advantages of high energy density in the past, they cannot compensate for the "side effects" caused by safety, longevity, high and low temperature resistance, and charging time.

　　The safety of the power battery depends more on the material itself and the manufacturing process, and the high safety of the lithium titanate battery effectively solves the problems caused by potential safety hazards to the promotion and application of new energy batteries. After nearly ten years of development and on the basis of building a closed-loop industrial chain, Yinlong is committed to the research and development and innovation of lithium titanate technology. With Yinlong titanium battery 6 minutes fast charge and discharge, wide temperature resistance (-50℃—+ 60℃), 30-year cycle life, no fire, no explosion, high safety, and high efficiency. Through continuous research and development, the fourth-generation high-energy-density lithium titanate battery has reduced the cost by 40% and increased the energy density by 60% compared with the third-generation. While overcoming bottlenecks in the industry, this technological advantage is applicable to many fields such as new energy vehicles, energy storage, and airport shuttles. It has been recognized by well-known bus companies including Beijing Public Transport, and has operated more than 40 cities so far.

　　When talking about why it bought the American Austrian Titanium and chose lithium titanate in the past, Wei Yincang used a football game to make a vivid metaphor. He said that if you score six goals to be the champion, you must advance five goals to ensure the chance of success. For the power battery, it must have the life and cost-effective requirements that compete with traditional cars, and it must have the ability to withstand differential temperature. For the hot and cold demand across the northern and southern hemispheres, the charging time must compete or be equal to the refueling time, and the safety performance is better than that of traditional petroleum and internal combustion engines. For this reason, Yinlong chose a technical route of reverse thinking, and continued to score the last "ball"-energy density on the basis of the advanced "five balls". Wei Yincang said that at present, there are not many products that can compete with lithium titanate in terms of safety, high and low temperature resistance, cycle life, and charging time. He also said that the energy density of the fifth-generation lithium titanate battery next year will surpass that of the lithium iron phosphate battery, the original five advantages will remain unchanged, and the conditions for mass production are already available.

　　Broad prospects: Yinlong Titanium is extraordinary due to innovation

　　Yinlong’s innovative business model is also based on the five technological advantages of Yinlong’s titanium battery: long life, wide temperature resistance, high safety, fast charging and discharging, and industrialization. The innovative business model of "10-year warranty, vehicle replacement, and win-win for all parties" does not require the government to invest too much money to achieve a win-win situation for the government, buses, car companies, and finance. Yinlong will also continue to improve its service level, so that the market will be more at ease and customers will be more at ease.

　　Looking at the current development status of the new energy industry, the technical level of power batteries is the key to the development of new energy vehicles. Its cost, technology, and manufacturing levels determine the cost, driving range, performance, and comfort of new energy vehicles. Therefore, if my country's new energy automobile companies want to survive in the post-subsidy era, they must work hard on the research and development of power battery technology.
