When the high-nickel ternary became the goal pursued by all domestic power batteries, BAK relied on its own accumulation in the field of 18650 cylindrical batteries to quickly occupy the technological high ground.

　　At the recent CIBF exhibition, Shenzhen BAK Power Battery Co., Ltd. (hereinafter referred to as "BAK") brought the latest 18650-3. 0Ah high-energy core products and battery modules, and displayed the Haima ME300 battery pack and JAC iEV7S car using BAK batteries. At the same time, Dr. Zhaojun Luo, chief engineer of BAK, delivered a keynote speech at the exhibition forum, sharing the latest developments in BAK battery technology research and development and market applications.

　　“BAK’s accumulation of cylindrical battery technology is not lost to the international giants.” BAK’s chief engineer, Dr. Zhao Zhaojun Luo, said in an interview with OFweek Lithium Grid that the company’s 4.8Ah21700 cylindrical battery has begun small batch samples and is expected to be the fourth this year. Mass shipments can be achieved in the quarter.

　　As a leading power battery company in China, BAK Battery always pays attention to product innovation and upgrade, and continuously pursues the continuous improvement of core performance of batteries such as safety and energy density. The key product exhibited by BAK in this exhibition is the 18650-3. 0Ah BAK high-energy core that has just been launched. This battery represents the highest energy density of the domestic 18650 system single cell.

　　It is understood that BAK 18650-3. 0Ah high-energy core products adopt advanced fully automatic production lines and have been mass-produced in BAK Industrial Park in Zhongmou, Zhengzhou, with a production capacity of 6.5 GWh and a daily output of 2 million units. They are currently on the market. application.

　　While pursuing high energy density, solving the problem of fast charging is also a pain point for users. Luo Zhaojun introduced that BAK's 3.0Ah high-energy core has high energy density, which can help new energy vehicles to achieve an ultra-long cruising range of 500 kilometers. Its high-efficiency and fast-charging characteristics are also very interesting. The entire vehicle can be charged up to 80% of electricity in 48 minutes. , In extreme emergency mode, it can travel 60 kilometers in 10 minutes.

　　How to ensure the safety of power batteries while pushing up the energy density is a problem that plagues many battery manufacturers. BAK Battery's approach is to strictly control the quality of the battery cells in terms of structural design, top safety valves, positive and negative materials, and production processes. This also brings a safety record of zero accidents for BAK batteries so far.

　　Dr. Luo Zhaojun said: “BAK has been developing 18650-3. 0Ah batteries since 2015. It took three years to complete the chemical design freeze and process design freeze, and successfully solved the directional blasting technology of a high-capacity single battery cell. , To implement the "Fail-Safe" concept of the failure of a single cell in the entire package and the integrity of the entire package."

　　At the CIBF technical exchange meeting, Dr. Zhaojun Luo was invited to deliver a keynote speech on "Continuous Technology Innovation of BAK Power Battery", sharing the latest achievements of BAK Battery in the field of power batteries and the next development direction. In addition to the gratifying results of the current 18650 cylindrical cell system, BAK’s 21700 cells have also completed multiple offline internal tests and are expected to be mass-produced in the fourth quarter of this year.
