China’s new 600Wh lithium EV battery could be the potential cure we’ve been seeking for range anxiety.
Range anxiety is one of the biggest ‘pitfalls’ of EVs, with many customers holding back on buying an electric car due to fears of running out of battery.
Companies around the world are looking for a solution, and a Chinese team might have come up with the answer.
Its new battery has twice the range of the Tesla advanced 4860 cell, and could eliminate range fears once and for all.

How much range does the battery have?
Currently, a pilot production line has been set up for the new EV battery.
The team behind it is from Tianjin University, and they say it has 660 watt-hours per kilogram of energy density.
For context, the Tesla 4680 battery has 300 watt-hours per kilogram of density.
Even more interesting is that BYD’s Blade Battery has an energy density of just 150 watt-hours per kilogram.
In terms of mileage, the team behind it has not yet released any figures.
For context, in the base Model Y standard range, the 4680 battery packs have 311 miles of range.
But in longer-range models, it approaches the 400-mile mark.
If we crudely say double the density is double the range, the Chinese battery could last for up to 800 miles in some cases.
How bad is range anxiety?
Range anxiety has been a problem with electric cars for some time.
It stems from a fear of running out of battery on the road, without an EV charger being nearby.
As electric vehicle charging points become more common, though, that will become a thing of the past.
In fact, it then becomes no different from wanting to find a gas station for an ICE car.
But it is still something that holds many people back from buying an electric car.
Should this battery be put into production, it could double or quadruple the range of many EVs.
An electric car of 600 miles or more would shatter any fears of range anxiety and eliminate it altogether.
If this is the EV battery that cracks the code, electric cars could become the choice for many.
