80% charge in 9.8 minutes! Guoxuan High-tech releases three new products and technologies

HEFEI, May 18, 2024 /PRNewswire/ -- On May 17, with the theme of "To the New World", the 13th Technology Conference of Gotion High-tech was grandly opened at its Baohe headquarters. Aiming at the core needs and pain points of users' most concerns, such as high safety, long battery life, and fast charging, Gotion High-tech released three new products and technologies, including the "released and mass-produced" 5C ultra-fast charging G-eng battery, high-nickel ternary cylindrical Xingchen battery, and the hot all-solid-state battery technology in the industry. 18 academicians from home and abroad, and more than 20 experts from first-class universities, industry institutions and well-known companies attended the conference and delivered speeches.

5C ultra-fast charging G-moment battery: 80% charge in 9.8 minutes

"Let supercharging become standard!" The brilliant announcement by Dr. Cao Yong, Vice President of Gotion High-Tech Industrial Research Institute, made the 5C super-fast charging solution of G-eng Battery the focus of the whole audience. It can replenish 80% of energy in 9.8 minutes of charging and 90% of energy in 15 minutes of charging. It supports full-scenario applications such as pure electric and extended-range hybrid, and covers lithium iron phosphate, lithium iron manganese phosphate and ternary systems. The battery pack products equipped with G-eng battery cells have many innovative designs and safety applications in design. The super-large module-free design reduces the number of parts by 30%. The system's Z-direction ultra-thin design can adapt to a variety of models such as coupes and SUVs. The direct connection BMS+FDC design reduces the wiring harness by 80%. Through nano-insulation and ceramic composite insulation, "0" heat diffusion between battery cells is achieved. Cao Yong said that the large power and super-fast charging capabilities of the G-eng battery system are inseparable from the breakthroughs in materials and full-stack self-developed battery cell technology. The company's self-developed 1000V electrical architecture and ASIL D software and hardware platform are combined with the company's self-developed Gotion Care+ cloud monitoring platform, which effectively achieves a balance between fast charging and safety.

At present, G-eng batteries are promoting the summer standards for complete vehicles.

High-nickel ternary Xingchen Battery: The seventh-generation factory reduces comprehensive manufacturing costs by 50%

Cheng Qian, president of Gotion High-tech's Asia Pacific business and dean of the International Engineering Research Institute, said in the release that the new generation of Star Battery is the company's latest ternary system 46 large cylindrical product, which has high energy density, ultra-long cycle life, and can achieve 4C fast charging. It will be produced by Gotion High-tech's seventh-generation factory.

The new generation of Star Battery uses the second-generation silicon-carbon material and ultra-fast electrolyte developed by Guoxuan High-tech, and adopts gradient electrodes and new structural parts in design, achieving high energy density and fast charging of the battery cell. Its mass energy density reaches 285Wh/kg, volume energy density reaches 775Wh/L, and it can maintain 70% of its health status after 2,500 cycles at room temperature, achieving an ultra-long cycle life. The fast charging performance of the Star Battery is also excellent, and it can achieve 4C fast charging, replenishing energy from 10% to 70% in 9 minutes.

The breakthrough of Star Battery comes not only from product research and development, but also from the vertical integration of Guoxuan High-tech's advanced manufacturing and supply chain, which makes the product have obvious comprehensive advantages. According to Cheng Qian, Guoxuan High-tech's seventh-generation factory has achieved micron-level precision production, which is the highest level in the industry; the company has been vertically integrating and recycling materials for many years, and it is expected to reduce manufacturing costs by 50%.

All-solid-state technology Jinshi battery: mass density can reach 350Wh/Kg

Guoxuan High-tech officially entered the field of solid-state batteries, with the protagonist being "Jinshi Battery". Dr. Pan Ruijun, chief engineer of the all-solid-state battery project, introduced that the team achieved a technological breakthrough in the material end of all-solid-state batteries through micro-nano solid electrolytes, ultra-thin film-coated single crystal positive electrodes, and three-dimensional mesoporous silicon negative electrodes. At present, the 30Ah all-solid-state battery cell can achieve a mass energy density of 350Wh/kg and a volume energy density of 800Wh/L, which is 40% higher than the mainstream ternary lithium battery. The number of cycles of its battery system can reach more than 3,000 times, which can easily achieve a million kilometers of mileage in the entire life cycle of electric vehicles. At present, Jinshi Battery has passed the 200-degree hot box test at one time, and its safety far exceeds the national standard requirements. The PACK designed based on Jinshi Battery has an 80% mass grouping rate, a system energy density of 280Wh/kg, and a single-charge range of up to 1,000KM. The manufacturing process of solid-state batteries has always been a difficulty that has plagued the industry. Pan Ruijun shared the team’s breakthrough progress in manufacturing technology, saying that the company has achieved innovation from 0 to 1 in solid-state batteries, from mold batteries to automotive-grade battery cells.
