Farasis Energy announced that it has developed a 330Wh/kg high energy density battery

On April 1, Farasis Energy released an announcement stating that the company's research and development team has developed and verified the next-generation electric vehicle battery with an energy density of 330Wh/kg. This power battery technology limits the huge expansion of silicon materials during charging and discharging, and is combined with auxiliary materials such as single-walled carbon nanotube conductive agents and new adhesives to build a stable electrode system.

Compared with the existing graphite negative electrode, the 330Wh/kg high energy density battery can significantly reduce the negative electrode surface density, improve the product's energy density and charging safety performance, and achieve a double improvement in battery energy density and cycle performance. At the same time, through the coordination of the chemical system, the high dynamic performance of the battery is achieved, so that the battery can still provide about 90% of its capacity at a temperature of minus 20°C. This power battery technology has high energy density and the advantages of long life and high dynamic performance, filling the current gap in the industry. At the same time, the battery's high temperature performance is also excellent, and both high temperature storage and high temperature cycle performance are higher than the industry level.

So far, the technology has passed the company's internal test. The company will apply for the new national standard GB38031-2020 test of the China Automotive Engineering Research Institute Co., Ltd. Testing Center according to market demand. The test period is expected to be about 3 months. After the test, it can be sold and used.
