Yinlong: Enhancing the technological innovation of lithium titanate battery

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

In 2016, the entire lithium battery industry continued to fluctuate in the continuous fluctuations of national policies, but overall maintained an upward trend. Affected by the growth of new energy vehicle market and national policies, the power battery industry has set off an unprecedented wave of capacity expansion and continued into 2017, which also directly boosted the rapid growth of the lithium battery equipment market.

Attacking five into 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 state's subsidy policy is biased towards energy density, the industry has experienced a high energy. The trend of gradually decreasing density, although some lithium batteries in the past have the advantage of high energy density, but cannot make up for the "side effects" caused by the safety, life, high temperature and low temperature, 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 problem that the safety hazard brings about the promotion and application of the new energy battery. Through nearly ten years of development and building a closed-loop industrial chain, Yinlong is committed to the research and development and innovation of lithium titanate technology. With Yinlong titanium battery, it can charge and discharge quickly and withstand wide temperature (-50°C-+). 60 ° C), 30 years of cycle life, no fire, no explosion, high safety, high efficiency of the five major advantages. Through continuous research and development, the fourth-generation high-energy density lithium titanate battery has a 40% lower cost and a 60% higher energy density than the third generation. While overcoming the industry bottleneck, this technological advantage is applicable to many fields such as new energy vehicles, energy storage, and airport shuttle buses. It has been recognized by well-known bus companies including Beijing Public Transport, and has operated more than 40 cities.

When it comes to why the United States chose to purchase lithium titanate in the past, Wei Yincang used the football game as an analogy. He said that if the six goals are champions, then five balls must be advanced to ensure the chance of success. For the power battery, it must have the life and cost performance requirements of competition with the traditional car, and must have the temperature difference performance. The hot and cold demand across the northern and southern hemispheres, the charging time should be competitive or flat with the refueling time, and the safety performance is better than the traditional oil and internal combustion engines. To this end, Yinlong chose a technical route of reverse thinking, and continued to score the last "ball" based on the advanced "five balls" - energy density. 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 will surpass that of lithium iron phosphate battery next year. The original five advantages will remain unchanged and the conditions for mass production will be available.

Broad prospects: Yinlong titanium is extraordinary for innovation

Yinlong's innovative business model is also based on the long-life, wide-temperature, high-security, fast charge-discharge and industrialization advantages of Yinlong titanium battery. For this reason, Yinlong proposed “0 yuan for car purchase and ten-year lease”. The innovative business model of “10-year warranty, complete 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, public transport, car companies and finance. Yinlong will also continue to improve its service level, making the market more reassuring and giving customers peace of mind.

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

In order to overcome the short-lived problem of new energy vehicles, Yinlong successfully developed the titanium-hydrogen powertrain in 2016 with the advantage of the whole industry chain, combining the high power density of lithium titanate battery and the high energy density of hydrogen fuel cell. Provide new ideas and new countermeasures to overcome the problem of driving mileage of new energy vehicles. In order to make consumers more comfortable and convenient to use new energy vehicles, it is also an inevitable trend to develop battery technology with high safety, fast charge and long life. With the advancement of technology and in-depth study of lithium battery materials, lithium titanate has encountered the problems will also be solved, and the market value and application prospects will be more broad.
