How to Seek Development of Lithium Electric Industry Inrush Lithium Electric Factory in China

In 2015, the global output of lithium-ion batteries was 100.75 GWh, and power cells accounted for 28.26 %. According to the latest data from the China Automobile Association, in January and February 2016, China produced 37,937 new energy vehicles and sold 35,726 vehicles, an increase of 1.7 times that of the previous year. As the "heart" component of new energy vehicles, the power lithium battery has ushered in the "golden age" of industry development.

Faced with such a huge market, domestic lithium battery manufacturers have expanded their production capacity, and the industrial chain is in the middle and lower reaches of the crazy "investment boom." Lithium-electric industry in China.

Talk about Lithium Battery Safety: Materials Should be Developed with Multiple Routes

Talk about lithium battery related production projects, whether in the production stage or the application stage, safety is the first factor considered by enterprises. In response to the recent domestic "three-element lithium battery" turmoil, Sandler Group and Thornton New Energy Chairman Wen Yibo told the OFweek lithium power grid in an exclusive interview that materials are not the only criteria for judging the safety of lithium batteries. In addition to the material itself, the battery management system (BMS), the consistency of the battery pack, and the degree of compatibility with the vehicle will jointly determine the safety performance of lithium cells.

It is reported that the battery PACK, manufacturing process and use of the three, accounting for more than 90 % of the battery impact on the safety of the vehicle. "Electric cars that have caught fire so far in the country are mostly lithium iron phosphate batteries, but that doesn't mean anything," he added. The impact of positive materials on the safety of the vehicle is not as great as the outside world thinks. It is arbitrary to judge the safety of the battery solely on the positive material of the core, without scientific basis and data support. "

It is reported that the positive materials developed and produced by Hunan Thornton New Energy Co., Ltd. (hereinafter referred to as "Thornton New Energy"), which was invested and built by the Sandar Group, include lithium iron phosphate, ternary materials and lithium manganese acid. In the next development, Thornton New Energy will uphold the multi-route development policy, step up the research and development of battery technology, and ensure the safety performance of lithium battery products.

Talking about Power Battery: "Retired" Echelon Utilization is feasible

According to theoretical calculations, the life of a power cell from the beginning of use to the end of the battery is about 20 years. When the power battery can only fill 80 % of the original power, it is not suitable to continue to use on electric vehicles, that is, face "retirement." According to the forecast of the China Automotive Technology Research Center, by 2020, the total scrap volume of electric vehicle power batteries in China will reach 120,000 to 170,000 tons. The recycling and utilization of power cells is an urgent problem. Can the ladder use work?

In this regard, Wen Yibo said that echelon utilization is completely feasible in theory, but at this stage still faces two problems: First, the number of abandoned power cells is not enough to support large-scale power generation projects, and second, how to properly recycle these batteries.

The energy storage battery of an energy storage project is of a large scale. If the power battery is to be used as a storage energy, a large number of battery packs are required. This is not possible for the current amount of waste, but it can be expected that new energy vehicles will be popularized in the future. In other words, the current echelon utilization is only suitable for small-scale applications.

On the issue of proper recycling, recently, the five ministries and commissions have explicitly proposed to establish a coding system and establish a traceability system for battery recycling and reuse.

“Many companies are working on the remaining energy of power batteries, including Beijing and Zhejiang companies under the State Grid, and investing in research and development projects, but the progress is relatively slow,” said Sun Dongdong, new energy analyst at OFweek Industry Research Center. As far as the current industrial situation is concerned, due to the different battery routes, battery specifications and battery evaluation requirements of different car companies in China, the number of batteries is too large, resulting in excessive production dispersion, and also for the 'post market'. That is, the use of the ladder brings more difficulty."

Wen Yibo also expressed his concern. It is good that power cells can be traced back, but it is not easy to realize echelon utilization. Thornton New Energy has been working on the dynamic tracking technology of batteries, which can be specific to the positioning of vehicles and will help the realization of gradient utilization in the future.

On the Way to Development: Production Capacity and Technology Needs Attention

As the largest new energy industry base in the south-central region and the most complete industrial chain, Thornton New Energy is invested and built by the large professional environmental protection company Sandar Group. The company has a complete lithium electric ecological chain, which covers lithium battery cathode materials and dynamic lithium batteries. Battery industry chain integration products. Lithium battery products are widely used in pure electric passenger vehicles, pure electric commercial vehicles, pure electric special vehicles, smart power grids, wind and photoelectric storage energy, large-scale UPS, base stations, high-end electric tools and other fields.

On March 10, Thornton New Energy and Guohong Automobile Co., Ltd. signed the "Framework Agreement for Cooperation on New Energy Vehicle Power Battery Project" and reached a cooperation issue for 50,000 new energy vehicle power lithium battery assembly systems.

In addition, Thornton New Energy also "holds hands" with well-known new energy car companies such as Zhongtai, Tongjia and Meihua, which has a positive role in driving the development of the lithium industry in Hunan and even the country.

It is understood that since the establishment of the Xiangtan Jiuhua Economic and Technological Development Zone, Thornton New Energy has continuously increased its production capacity to meet market demand. In September last year, it launched the preparatory work for the second phase of the project and will use international advanced equipment for production. It is expected to be completed by the end of May. The third phase of the project is expected to start at the end of this year.

Wen Yibo said that under the rapid development of lithium electric energy and the increasing acceptance of lithium electric products such as new energy vehicles, the development prospects of the new energy industry are very broad, and Sande has entered this industry in advance and done a good layout. After the completion of the second phase, it will reach 1 billion Ah core and 30,000 tons of positive materials. In the third phase, 2 billion Ah and 50,000 tons of positive materials will be completed. The company expects to achieve a core size of 3 billion Ah or more by the end of 2018.

He said the most important thing is to continuously improve better technology and better inheritance, to adapt to the market and lead the market. The company will continuously increase its own technology research and development efforts to improve product performance. Improve after-sales service while expanding production capacity. At that time, Thornton will become one of the most complete new energy leading enterprises in the domestic scale and industrial chain.
