Power battery which strong silver titanium with strength to speak

The past 2016 was a symbolic year for the transformation of pure electric power in the world. China's new energy vehicles entered the growth stage from the product introduction period, and the market development of pure electric drive vehicles in the country has achieved breakthroughs. In 2016, China produced 517,000 new energy vehicles and sold 507,000 vehicles, an increase of 51.7% and 53.0% respectively over the same period of the previous year. Objectively speaking, it has become the world's largest producer and seller of new energy vehicles.

With the implementation of the “Thirteenth Five-Year Plan” policy, it can be foreseen that the strategic objectives of China's new energy vehicle key special projects are electric, lightweight, and intelligent, and urgently need to upgrade technologies to make the new energy automotive industry more competitive. The power battery has always been in a strategic position for the development of new energy vehicles, and can be described as a top priority.

In particular, under the current rapid growth of the production and sales market, issues such as insufficient high-end capacity of power batteries, low-end excesses, and products that do not meet market demand have been further aggravated. So what kind of battery really adapts to the market?

Power Battery Group Crushes Silver Dragon to Show "Titanium Strength"

At present, lithium ion batteries widely used in the field of new energy mainly include ternary lithium batteries, lithium iron phosphate batteries, and lithium titanate batteries.

The more advanced three yuan lithium battery industry is Korea, Japan and China. Due to the high density of ternary lithium batteries and the relatively long cruising range, the current application in the field of passenger vehicles has achieved remarkable results. However, there are deficiencies in safety, high temperature resistance, and longevity. In 2016, the Ministry of Industry and Information Technology once suspended the inclusion of a ternary lithium battery passenger car in the list of recommended models for the promotion and application of new energy vehicles. Although the ban was officially lifted in 2017 for three yuan lithium battery passenger cars. Use, but to meet the "electric passenger car safety technical conditions."

At present, countries that have mastered more mature mass production technologies in the field of lithium iron phosphate mainly include the United States, Canada, and China. Compared with ternary lithium batteries, lithium iron phosphate batteries are widely used in pure electric buses because of their stable safety performance, high temperature performance, and light weight. However, there are deficiencies in low temperature performance and tap density of positive electrode materials, and there is no advantage in terms of work efficiency.

There is also a lithium-titanate battery that is currently receiving much attention from the market. Lithium titanate battery is the longest-lasting battery with the highest safety in lithium battery, and can achieve fast charge and discharge for 6 minutes and a wide temperature resistance of -50°C~60°C. On the life cycle, ordinary lithium ion batteries are about 1000-2000 cycles, and lithium titanate is 30,000 cycles, which is 15 times that of the former. However, the battery of this material has a natural defect: the low energy density limits its mileage. It is reported that companies currently possessing lithium titanate materials and achieving momentum and industrialization applications have only two global perspectives, Japan’s Toshiba and China’s Yinlong New Energy. It is worth mentioning that Yinlong New Energy has mastered the international advanced "Lithium titanate power battery technology" through holding the United States Austrian titanium nanotechnology company, and by virtue of technology research and development, the fourth generation of high energy density lithium titanate is currently introduced. The battery - silver titanium titanium, compared with the third generation cost reduction of 40%, energy density increased by 60%. This achievement has been highly recognized in the market and opened a brand new page for power battery.

In the long term, the market is the best touchstone for technology

In addition to advanced technology, Lithium Titanate batteries also have cost advantages. Yinlong Titanium's cycle life has been increased to more than 30,000 times, and its cycle life is more than 30 years. According to the calculation of the cost of the single battery, the lithium titanate battery is 1.5-2 times that of the conventional battery. From the perspective of the service life cost, the cost per use of the lithium titanate battery is only 15%-50% of the conventional battery. It can be seen that the use of lithium titanate batteries can significantly reduce the cost of lithium-ion power battery modules. Yinlong titanium batteries can be used to manufacture large-scale energy storage and power lithium batteries, and their longevity advantages provide lithium titanate batteries with a reusable function. Vehicle lithium titanate batteries can continue to be used in energy storage after they reach the end of their service life.

In addition to the above-mentioned ternary lithium, lithium iron phosphate, and lithium titanate, the future energy storage technology will further diversify, such as the upcoming market of fuel cells, will provide users with more choices. In practical applications of lithium-ion power batteries, safety, cycle life, energy density, wide temperature, power density, charge and discharge speeds are all important factors affecting large-scale commercialization. Batteries have a wide range of applications. Each type of battery has its own market. The market will be the best touchstone for technology.
