What if charging your EV became a once-a-week thing? That is the promise behind a new electric vehicle battery unveiled by Chinese researchers this week. According to the scientists, the battery could power a car more than 1,000 kilometers (620 miles) on a single charge.

If that number holds up outside the lab, it could push EV range into territory where gas cars no longer have the obvious advantage. And yes, that’s a pretty big deal.

The breakthrough is all about the chemistry

The upgrade comes from a new battery chemistry developed by researchers led by Chen Jun at the Chinese Academy of Sciences. Their design replaces certain oxygen atoms with fluorine atoms inside the battery’s electrolyte system. That tweak improves two things EV engineers obsess over:

Energy density (how much power a battery can store)
Stability (how safely that power can be used)

In lab tests, the battery reached over 700 watt-hours per kilogram, which is dramatically higher than many current EV batteries.

For context, most modern EVs top out somewhere between 400 and 600 km of range. That’s enough for daily driving, but long road trips still require careful charging stops. A 1,000-km battery changes that equation, as it means you could drive from New York to Detroit without needing to plug in. Or it could handle most people’s entire week of commuting on one charge.

Even in extreme cold, the new battery holds up. According to scientists, when tested in a temperature of around -50°C, it reportedly maintained a strong performance of about 400 Wh per kilogram.

China is doubling down on battery innovation

This development is not happening in a vacuum. China already dominates global EV battery production, with companies like BYD and CATL controlling more than half the global market.

Now scientists, automakers, and battery manufacturers in the country are increasingly working together to push new battery designs into vehicles faster. This latest project involved scientists working alongside FAW Group and China Automotive New Energy Battery Technology Co.

One version of the new battery, developed with FAW Group’s Hongqi brand, has already been installed in a prototype vehicle. So you can expect vehicles using these batteries to start getting mass-produced by 2026.
