18650 lithium battery is currently the most mature power battery product

18650 is currently the most mature power battery product. Without safety, there is no maturity...Maturity also means safety, efficiency, low cost, high consistency and high reliability. "At the "13th China International Battery Technology Exchange/Exhibition (CIBF2018)" held in Shenzhen a few days ago, Dr. Wu Fuquan, Chief Engineer of Shenzhen CSIP Power Battery Co., Ltd. praised the 18650 battery. This is not just because CSIP battery’s consistent focus on 18650 battery is also due to the fact that CSIP battery found too many excellent characteristics of 18650 battery in the nearly extreme research and development process of 18650 battery, and gradually showed these characteristics on various types of 18650 battery. Use 18650 battery to hit a piece of his own world.

The safety issue of power batteries is a word that runs through the conversation. "For lithium batteries, safety is 1, and it is valuable to add a lot of zeros, but if safety is not solved, it is meaningless to pursue other performance improvements. "The safety of CSIP batteries is also what CSIP is most proud of.

The forthcoming "Safety Requirements for Lithium-ion Power Batteries for Electric Vehicles" stipulates that the acupuncture test in the forced inspection of the power battery is cancelled. In this regard, in the actual use process, acupuncture rarely occurs, but it is the battery module. Thermal runaway has always been the focus of attention from all walks of life on the safety of power batteries. Despite the cancellation of acupuncture testing, battery companies have to work harder on battery thermal runaway caused by a variety of factors to ensure that batteries are safer.

The almost demanding requirements actually originate from the “reverse force” of the vehicle manufacturers in terms of safety. "Now the national standard requires no explosion and no fire within 5 minutes. In fact, it is for large square batteries, but cylindrical batteries can't have this problem no matter how long. "The requirement of the vehicle manufacturer from us is that you can never explode and catch fire. "Because of this, CSIP batteries are "broken" for battery safety. The high nickel material used in the latest 3.0AH 18650 battery cell is very important for the control of the heat release of the battery cell. The choice of positive electrode material is successful. Basically, it can solve more than 60% of thermal runaway problems. In addition, by doing enough homework on the hardware structure and overall module protection, you can 100% avoid thermal runaway.

The 2.9AH high nickel + silicon alloy 18650 battery that rolled off the assembly line in 2015 became the first battery cell product in China that passed the entire package of thermal runaway test; the 3.0AH 18650 battery cell passed the thermal runaway test on the entire vehicle; 3 ．2AH batteries are planned to go offline in 2018, and orders are expected in 2019; 4.5AH products have been developed and can be mass-produced at any time; 4.8AH batteries are undergoing small-batch trial production and are already in small-batch installation Car test...

It is based on years of deep cultivation of 18650 batteries that CSIP batteries have been continuously developed along the road of cylindrical batteries, and continuous product layouts are being carried out. Square batteries and soft-pack batteries will also become important product lines for the future development of CSIP batteries.

After ten years of intensive cultivation, CSIP batteries have achieved remarkable results in cylindrical cells. And continue to provide support for BMW, SAIC-GM, FAW, Wuling, Yundu, JAC, Zotye, Leapfrog and other well-known domestic and foreign automakers. Raising the goal for 2018, in addition to mass production of 3.2AH and 4.8AH batteries, it is still hoped that the safety problem of the power battery pack can be completely solved at the system level, and "to protect the new energy industry with safety and low cost. healthy growth."
