According to CCTV Finance, Fujian Ningde, the world’s largest power battery production base, produces a quarter of the world’s electric vehicle batteries, and an average of 1,000 electric vehicle batteries are offline every minute.
Naijatechnews learned that the energy density of the battery is a key indicator that determines the cruising range of an electric vehicle. In the past 10 years, the scientific research team has doubled the energy density of battery packs by upgrading chemical materials to 180 watt-hours per kilogram, increasing the range of electric vehicles from less than 200 kilometers to more than 700 kilometers.
In the case that chemical materials cannot achieve major technological breakthroughs in the short term, this is already approaching the limit of battery energy density. Can a breakthrough be made in the structure?
After one year, the scientific research team used strict production technology to strictly control the average thickness deviation of batteries with a thickness of 60 mm within 0.1 mm, and realized the idea of allowing batteries to be directly integrated into the battery pack. The energy density of the battery is increased to more than 220 watt-hours per kilogram, thereby increasing the cruising range of electric vehicles to more than 1,000 kilometers.
Not only that, they also set a new record: The battery pack developed only needs to be charged for 15 minutes, which can provide a car with a battery life of 400 kilometers. A year ago, such a charging speed was considered impossible.
