Domestic 18650 battery breaks through 3.0Ah BAK 3.0 high energy core has many features

On May 16th, Shenzhen BAK Power Battery Co., Ltd. held a new product launch conference for the BAK 18650-3.0Ah high-energy core in Zhengzhou. This means that BAK Battery is the first to achieve mass production and market application of 18650-3.0Ah batteries. The domestic energy density of 18650 batteries has reached the international leading level. The current capacity of the BAK 3.0 high-energy core is 6.5GWh, and the daily output can reach 2 million. It will be the standard product with the highest performance in the 18650 system, which can support the ultra-long cruising range of 500km for electric passenger cars.

In recent years, domestic policies have led to the continuous improvement of the energy density of power batteries: "China's long-term development plan for the automotive industry" clearly plans that by 2020, the power battery monomer energy will reach 300Wh/kg or more, and the 2018 new energy vehicle subsidy threshold will be further improved. It can be seen that under the premise of ensuring safety, the increase of energy density of power batteries is increasingly important for the development and promotion of the electric vehicle industry.

In response to the government's call and adapt to the needs of the users' market, BAK Battery has taken the lead in advancing the application of domestic high-energy cylindrical batteries to help the rapid development of China's new energy automobile industry. At present, a number of electric passenger vehicle manufacturers have in-depth communication and loading test with BAK on 3.0 high-energy core products. The new power-making zero-running car signed a strategic contract with BAK Battery on the day of the conference, and the two parties will jointly promote the application of the 18650-3.0Ah product.

According to the agreement, the zero-run car purchases tens of millions of BAK battery packs. At present, both parties are in the joint testing phase of the whole vehicle, and mass production will be delivered soon. As the cooperation between the two parties continues to advance, the zero-running car will become one of the first auto manufacturers to apply 18650-3.0Ah batteries in China.

Pan Wang, vice president of Shenzhen BAK Power Battery Co., Ltd. said: "Bick's previous market research shows that consumers' focus on electric vehicles is mainly on single-charge cruising range, charging convenience and fast charging technology, battery life, battery safety and cost-effective aspects. BAK 3.0 high-energy core will help improve the performance of domestic electric vehicles, and meet the various needs of users with the car companies, greatly enhance the driving experience."

The BAK 3.0 high energy core has the following features:

High energy, support long battery life: BAK 3.0 high energy core through the introduction of silicon-based anode material, high-nickel cathode material, and specially developed electrolyte, its energy density is up to 250Wh / kg, can achieve 500 kilometers long cruising range.

Charging is fast and convenient: high-energy materials realize high-rate charging and discharging, and the charging strategy design can effectively shorten the charging time and improve the charging efficiency. Taking the current running LP-S01 driven by the BAK 18650-2.75Ah battery as an example, the whole package is 36kWh, and the maximum cruising range is expected to be 360km, and the NEDC condition is 250km. In slow charging mode, it can charge 100% in 8-10 hours, and in fast charging mode, it can charge more than 80% in 48 minutes. In the extreme emergency mode, you can drive for 60 kilometers in 10 minutes.

Low attenuation, long life: Supports 3000 deep cycles and good high and low temperature discharge performance. The actual case shows that the battery attenuation of the first batch of new energy taxis in Beijing with BAK battery is less than 30% after driving 400,000 km.

High safety: symmetrical structure with uniform pressure release, safety valve to avoid thermal runaway, domestic independent development of positive electrode protection additive and 17 production process data strictly control the quality of the battery core, forming a four-fold safety guarantee system, bringing 0 accident protection.

High cost performance: Through large-scale, intelligent production and efficient output, and continuous material innovation to reduce costs, to serve customers with cost-effective battery products.

As the leading power battery company in the industry, BAK Battery always pays attention to the technical research and development of products, and constantly pursues the continuous improvement of energy density, leading the new standard of domestic ternary lithium battery industry. At the beginning of 2017, BAK has successfully developed 18650-3.0Ah products, and now BAK 18650-3.0Ah products are the first in China to be listed and put into market applications.

"BAK 18650-3.0Ah battery products are the first in China to release and achieve mass production. In the next two years, 18650 batteries will break through 3.0 to reach 3.3Ah, achieving the ultimate performance of the 18650 system. BAK also pre-lays 21700 products and has achieved mass production, in the future will provide higher energy and stronger power for new energy vehicles with a higher energy density of 4.5-6.0Ah." Pan Wang added.
