The Development Path of Yinlong for Lithium Titanium Battery

With the addition of powerful entrepreneurs such as Dongmingzhu, Wang Jianlin, and Liu Qiangdong, lithium titanate batteries are standing in the spotlight, lithium titanate batteries are getting hotter, and Yinlong New Energy is indispensable. At the seminar, Yaogaoliang, general manager of Yinlong New Energy Storage Division, and Zhanshiying, manager of the Research and Development Department of the Battery Research Institute, delivered keynote speeches respectively, sharing the battery technology progress of Yinlong New Energy, the status quo of energy storage development, and the operating business model. Wait.

Steadily Moving Silver Dragon Titanium Technology

The wet nanometer material manufacturing process and lithium titanate battery manufacturing technology are the core values of Yinlongtai. Yinlong New Energy has done a lot of innovative research and development work on lithium titanate materials.

In the field of negative materials, since the 1990s, graphite has firmly occupied a dominant position and has a high market share. Affected by national policies and markets, negative materials develop toward high specific energy, high charge and discharge ratio, high cycle performance, and lower cost. The titanium-silicon carbon negative electrode material developed by Yinlong New Energy, whose core particles are high-specific energy nanosilicon(theoretical capacity 3580mAh/g), the surface bread is covered with SiO2 secondary granulation, and the secondary particles are intermixed with graphite for three granulation. The surface bread is covered with Li4 Ti5O12 to form a Garnet structure of titanium silica carbon material.

In order to improve the material of titanium Silicon carbon negative electrode, Yinlong New Energy has developed two new batteries-titanium iron lithium battery and multivariate composite titanium lithium battery. Both of them use nanometer titanium Silicon carbon as the negative electrode, and both have the charging and discharging ability at -30 °C, and the charge and discharge doubling rate reaches 3C. The difference is that the mass ratio of titanium iron lithium batteries to energy & GT; 145 Wh/kg, cyclic life & GT; 10,000 times; Mass to energy ratio of multivariate composite titanium lithium batteries & GT; 220 Wh / kg, cyclic life & GT; 2000 times.

Hydrogen fuel cells are known as the "ultimate solution" for new energy automotive power cells. At present, the application in China is mostly in the category of demonstration, and has not yet achieved large-scale promotion. The advantages of hydrogen fuel cells are high energy density and low power density. With the change of road conditions and different driving habits, the power curve of hydrogen fuel cells is often changed arbitrarily, which seriously affects its service life. Yinlong New Energy combines the advantages of hydrogen fuel cell and lithium titanate battery to develop a hydrogen titanium power assembly system similar to a hybrid system.

Zhanshiying said that the hydrogen titanium power assembly consists of a silver titanium power pack, a hydrogen storage assembly, a fuel cell engine, a fuel cell supercharger, and a fuel cell air filter. Among them, the charging rate of the Yinlong Titanium power pack is 10C, the output power of the fuel cell engine is 30kW, and the range of the hydrogen storage assembly is more than 400km. Mr Zhanshiying said the system, which makes up for both lithium titanate and hydrogen fuel cells, would be mass-produced at yinlong new energy base in Tianjin by the end of 2017.

Yinlong's green energy storage ecosystem

Energy storage is the main application area of lithium titanate batteries, and it is also one of the two major development routes of Yinlong New Energy. The company has done a lot of layout in the energy storage field, and some projects are also leading in the world.

According to Yaogaoliang, in the application of energy storage in the power grid, the 2MW lithium titanate storage power station used for peak modulation of Baoqing South Power Grid in Shenzhen is China's first megawatt lithium titanate battery storage station and is also the world's first 10kV No Transformer directly connected to the grid battery energy storage system demonstration project. In addition, the 1MW energy storage device produced by Otis, a subsidiary of Yinlong New Energy, and the 10.5 MW wind power generation integration project of AES, El Salvador's grid stabilization system, and Zhangbei 2MW scenery energy storage projects are all in the power grid. Excellent performance in energy storage applications; In terms of industrial energy storage, Yinlong New Energy has Shanghai Electric 57.6 kWh energy storage project; In terms of household energy storage applications, the Shijiazhuang 20kW villa energy storage system of Yinlong New Energy Co., Ltd. seamlessly transferred to the battery system power supply after the municipal power supply was cut off, set up the human-machine interface, and can implement remote monitoring; In terms of container storage energy application, there is a 800KWh container type mobile charging tram equipped with a silver long titanium battery. It is worth mentioning that, in addition to the above fields, in terms of military energy storage, high-speed rail energy storage and port energy storage, Yinlong New Energy Lithium Titanium Battery Energy Storage Technology has deep applications.

Yinlong New Energy will deploy energy storage batteries on the power side, system side, load side, and user side, which will improve the economy of renewable energy power generation. It is important to realize peak filling, FM voltage regulation, improve power quality, and use electric vehicles to participate in the regulation of renewable energy power generation. From the business layout of Yinlong New Energy, it can be seen that from energy storage cell materials, energy storage core, energy storage cell BMS to energy storage battery batteries and various specific applications for energy storage and energy storage systems, and even remote monitoring platforms for energy storage cell systems, The green energy storage ecosystem with Yinlong Titanium as the core has already been formed, and Yinlong New Energy's lithium titanate energy storage technology has also acquired industrialization capabilities.

The Quartet's Innovative Business Model

A good business model is an inexhaustible driving force for the development of enterprises. The new energy automotive industry must continue to develop healthily and can not be separated from a good business operation model. Yinlong New Energy is based on the advantages of long life, wide temperature, high safety, and fast charging of lithium titanate batteries, and has developed a four-way win-win new energy passenger car promotion model.

The model is highly innovative. Yinlong New Energy leases public transport to local governments, public transport pays rent in the form of financial leases, and pays car payments in ten years. The oil and electricity difference can meet the rent payment amount. Yinlong New Energy provides a 10-year quality guarantee for the "three major systems of batteries, motors, and electronic control" and provides 24-hour "nanny" services, and provides backup vehicles to ensure that the operation is not affected, and eventually realizes the government, bus, and car companies. The four-way win-win. It is understood that this model has begun to implement, the industry believes that Yinlong new energy to promote the new energy passenger car mode of exploration worthy of recognition.

With the development of lithium-titanate battery, lithium-titanate battery has received more and more attention and its market share has been increasing. Bringing lithium titanate batteries to the center of the stage of Yinlong New Energy, its research and development work on lithium titanate batteries continues, and will explore more innovative business models to meet the market demand for lithium titanate batteries.
