Use solid-state battery technology to expand the future new energy vehicle market

January 4, 2021
At the beginning of the new year, the company reached a strategic cooperation agreement with a battery company in Shenzhen to introduce the company's most cutting-edge "solid-state high-capacity polymer batteries" for new energy vehicle loading, achieving a revolutionary breakthrough in new energy vehicle technology.

This company is a high-tech company focusing on the development and application of new energy technologies and new energy products. At present, the company has the world's most advanced and most mature laminated high-capacity solid-state lithium-ion battery technology, from material formulation, process manufacturing, The finished product application and system integration have independent intellectual property rights. The "single large-capacity solid polymer lithium-ion battery" developed and produced by the company has been reviewed by relevant units of the Ministry of Science and Technology and evaluated by relevant experts of the Ministry of Science and Technology: the technology is at the international advanced level in terms of monomer capacity, discharge rate, and energy density ratio. Ultra-low temperature technical indicators have reached the international leading level. The company's products have formed the product features of "three highs and one ultra-low temperature" (high safety, high specific energy, high power, large capacity, and ultra-low temperature).

The company’s "monomer large-capacity solid polymer lithium-ion battery" technology: mass-produced maximum monomer capacity reaches 3000Ah; mass specific energy is as high as 377Wh/kg; minimum operating temperature reaches -70℃ (discharge rate reaches 77.47 at room temperature %); Continuous discharge rate> 180C.

The product market application index ranks internationally. The energy density of 300~1000Km passenger car batteries is 250~300Wh/Kg, and the system energy density is 208~250Wh/Kg; the energy density of fast charging taxi battery in 5 minutes is 120~150Wh/Kg. The system energy density is 110~130Wh/Kg; the battery energy density for buses and heavy trucks is 190~210Wh/Kg, the system energy density is 160~185Wh/Kg; the aviation battery energy density is 200~330Wh/Kg, and the system energy density is up to 320Wh/ Kg; The energy density of energy storage battery products is 160~185Wh/Kg, and the number of charging and discharging of the system is more than 11000. Very low system self-loss, 150KW constant power charging and discharging efficiency>98%, 250KW constant power charging and discharging efficiency>96%, one-year storage charge retention rate>96%, and the internal resistance of the cell is less than 0.2 milliohms. The company's "single large-capacity solid-state polymer lithium-ion battery" has high-quality characteristics, and shows high safety, long battery life, high efficiency, short charging time, and long life in the use of power batteries; performance in energy storage Long cycle (up to 11,000 cycles), low loss (no more than 4% annual loss), high safety (no heat during system use) and other advantages.

Related experts believe that Junfeng Motor Company has a relatively strong ability to graft vehicle resources and commercial application capabilities. The strategic cooperation between the two companies will effectively improve the technical indicators and performance of "Junfeng" new energy and achieve a leap in the quality of new energy vehicles.
