With the continuous advancement of battery technology, the comprehensive performance of batteries has been significantly improved. After the gradual realization of ultra-long battery life of new energy vehicles, the anxiety of rapid recharge has become the main reason that hinders consumers from purchasing new energy vehicles. CATL has always focused on the essence of electrochemistry and continued to innovate in all aspects of materials, material systems, and system structures. It once again broke through the performance boundaries of lithium iron phosphate material systems and pioneered ultra-fast charging, long battery life, and high safety. Continue to lead the industry’s technological innovation trend.

According to reports, Shenxing Supercharged Battery redefines lithium iron phosphate batteries. In terms of cathode speed-up, it uses superelectronic network cathode technology, fully nanosized lithium iron phosphate cathode materials, and builds a superelectronic network to reduce the resistance to lithium ion escape. Make the charging signal respond quickly. In terms of negative electrode material innovation, Shenxing supercharged battery adopts the second-generation fast ion ring technology newly developed by CATL to modify the graphite surface, increase the lithium ion embedding channel and shorten the embedding distance, building a “highway” for ion conduction. “.

At the same time, Shenxing’s superchargeable battery uses a multi-gradient layered pole piece design to achieve a perfect balance between fast charging and battery life. In terms of electrolyte conduction, CATL has developed a new ultra-high conductivity electrolyte formula, which effectively reduces the viscosity of the electrolyte and significantly increases the conductivity. In addition, CATL also optimized the ultra-thin SEI film to further reduce conduction resistance. CATL has also improved the isolation membrane’s high porosity and low tortuosity pores, thereby improving the lithium ion liquid phase transmission rate.

The reporter learned that, while taking the lead in realizing 4C overcharging, Shenxing overcharged batteries also have the performance of long battery life, full temperature lightning fast charging and high safety through structural innovation, intelligent algorithms and other methods. On the basis of CTP3.0, CATL pioneered the all-in-one grouping technology, achieving high integration and high grouping efficiency, allowing the Shenxing supercharged battery to break through the performance upper limit of lithium iron phosphate and easily achieve a long battery life of more than 700 kilometers. .
Everyone is concerned about the status of batteries in low-temperature environments. Shenxing’s overcharged batteries can also achieve low temperatures and normal temperatures. CATL uses cell temperature control technology on the system platform, which can quickly heat to the optimal operating temperature range in low-temperature environments. Even in -10°C low-temperature environments, it can be charged to 80% in 30 minutes, and it can be charged at low temperatures. Acceleration does not fade below zero. Shenxing’s superchargeable battery uses an improved electrolyte and is equipped with a high-security coating separator, which provides a “double insurance” for battery safety. In addition, CATL uses intelligent algorithms to control the global temperature field, build a real-time fault detection system, and overcome many safety challenges caused by rapid energy replenishment, making Shenxing overcharged batteries have the ultimate safety level.
At the press conference, Wu Kai, chief scientist of CATL, said, “The future of power battery technology must be oriented to the forefront of the world and the main economic battlefield. Currently, users are beginning to shift from pioneer users to mass users. We need to make more common people Use cutting-edge technology and enjoy the dividends of technological breakthroughs.”
Thanks to its extreme manufacturing capabilities, CATL currently has a rapid transformation chain from technology to products to commodities, thus promoting the rapid mass production of Shenxing supercharged batteries. According to Gao Huan, CTO of CATL’s domestic passenger car division, Shenxing will be mass-produced by the end of this year, and electric vehicles equipped with Shenxing’s supercharged batteries will also be launched in the first quarter of next year. The advent of Shenxing super-chargeable battery is another milestone in the history of power battery technology development and will accelerate the process of comprehensive electrification.
