How about the fifth-generation lithium-titanate battery in Yinlong?

Where does Yinlong lithium-titanate battery technology come from?

According to the official website of Yi nlong New Energy Co., Ltd., in 2010, Zhuhai Yinlong Strategy held the US Ao Ti Nano Technology Co., Ltd., which holds the “most advanced production technology of global lithium-titanate battery materials”, thus “becoming the world” Leaders in green energy solutions and China's new energy brands rank among the best in the world. Yinlong invested more than RMB 300 million to acquire a 53.6% stake in American Titanium Nanotechnology Co., Ltd. and mastered the latest technology of the company's lithium-titanate materials. In 2012-2013, Yinlong acquired Zhuhai Guangtong Automobile and Shijiazhuang Zhongbo Automobile. Therefore, it has the qualification to produce a complete vehicle.

So far, there are only two companies that have lithium-titanate materials and have achieved power and industrial applications. Zhuhai Yinlong is one of them, and the other is Toshiba.

Lithium-titanate battery is still not the mainstream of battery technology. At present, domestic auto manufacturers use more ternary lithium batteries and lithium iron phosphate batteries. The ternary lithium battery dominates the global market. For example, the Panasonic 18650 battery used by Tesla belongs to the ternary lithium battery. According to BYD, commercial vehicles such as Dongfeng and Jianghuai use iron phosphate at this stage lithium battery.

Since the beginning of 2017, the price of raw materials for power batteries has risen one after another. The price of cobalt has been sung and titanium dioxide has been on the stage. Recently, the price of high-end titanium dioxide continues to rise. Some insiders believe that the fifth-generation lithium-titanate battery of Yinlong, the price increase of high-end titanium dioxide is mainly caused by lithium-titanate battery. Yes, yes, that is the lithium-titanate battery that has not been optimistic about the industry, but was won by Dong Mingzhu!

From the rise in the price of titanium dioxide, we may be able to conclude that “the lithium-titanate battery is already on fire”, but is it true that lithium-titanate battery is a “painting cake” or a “blueprint”, which remains to be seen Let's find evidence.

Yinlong's fifth-generation lithium-titanate battery next year

In Zhuhai Yinlong's view, the development of lithium batteries should be transformed from a single pursuit of high energy density to a balance of energy density, safety and operational efficiency. Therefore, the battery that is optimistic must have long cycle life, high temperature resistance, safety and stability. With five characteristics of fast charging and high energy density, lithium-titanate battery has the first four advantages. In order to overcome the problem of low energy mileage and short cruising range of new energy vehicles, Yinlong continues to upgrade the storage capacity of lithium-titanate battery. Density, it is expected that the storage energy of the fifth-generation lithium-titanate battery will exceed the lithium iron phosphate battery in 2018; on the other hand, the titanium hydrogen powertrain will be successfully developed in 2016, combined with the high power density of lithium-titanate battery and the energy density of hydrogen fuel cell. The high advantage, the development of hybrid batteries, this is also a good exploration.

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.

The lithium-titanate battery is a lithium ion secondary battery which is used as a negative electrode material for a lithium ion battery, lithium-titanate, and can be composed of a positive electrode material such as lithium manganate, a ternary material or lithium iron phosphate to form a 2.4V or 1.9V. In addition, it can also be used as a positive electrode, and a 1.5V lithium secondary battery is composed of a lithium metal or a lithium alloy negative electrode, due to the high safety, high stability, long life and green environmental protection of lithium-titanate.

Disadvantages of lithium-titanate

1. The energy density of other types of lithium-ion power batteries will be lower.

2, the problem of flatulence has been hindering the application of lithium-titanate batteries.

3. Relatively high prices for other types of lithium-ion power batteries.

4. There is still a difference in battery consistency. As the number of charge and discharge times increases, the difference in battery consistency will gradually increase.

Yinlong lithium-titanate battery analysis

Lithium-titanate battery pure electric bus mainly uses lithium-titanate battery in the characteristics of fast charging, long life, high temperature resistance, high safety, etc. It can realize 1:1 replacement with traditional fuel car. Charging pile can adopt 5: 1, that is, 5 cars with one charging pile mode to operate, greatly reducing the construction of charging piles and vehicle operating costs.

The long life and excellent high and low temperature performance of the lithium-titanate battery also ensure the stability of the operating vehicle. As for the actual operation effect, take the Beijing bus as the largest bus operation system in the world. As we all know, Beijing has a large population, and the operating pressure of Beijing public transportation is huge. The interval between the peaks of each line is only a few minutes. As early as 2008, the Beijing Olympic Games began to use pure electric buses, tried a variety of operating modes such as slow charging and power change, and also used a variety of power lithium batteries including lithium manganate, lithium iron phosphate, and ternary batteries. They were finally abandoned because they did not meet actual needs. Finally, after 127 experts discussed for a long time, Yinlong New Energy was selected, and Yinlong pure electric bus can enter Beijing bus. It undoubtedly proves the superiority of lithium-titanate battery, which is in line with the development law of new energy public transport, and also respects the market laws choice.

In summary, in fact, whether a certain technology is suitable for a certain field of application is not only determined by one or two simple technical indicators, but more depends on its actual application effect and customer recognition. With the continuous expansion of the production scale of lithium titanate batteries, combined with the construction of facilities such as wind energy storage in the future, and in conjunction with the unique business model of Yinlong, the pure electric bus of lithium titanate battery is the most likely new energy to get rid of financial subsidies, one of the models.
