China’s Contemporary Amperex Technology Co., Limited (CATL) has unveiled its latest battery cell technologies, which charge as quickly as filling up a gas tank while potentially lowering costs without compromise.
CATL has quickly become the world’s largest battery manufacturer by a wide margin. It is one of, if not the biggest, force for advancing electric transportation.
A big part of CATL’s success is due to its advancements in lithium-iron phosphate battery cells, also known as LFP. LFP cells are cheaper than nickel-rich batteries, but they used to have much lower energy density.
The Chinese battery manufacturers managed to close the gap somewhat while maintaining lower costs, resulting in LFP cells becoming popular for entry-level EVs.
Now, CATL is looking to do the same with sodium-ion batteries.
Like LFP cells, sodium-ion battery cells have the potential to be cheaper than more common Li-ion cells, but they also offer potential for superior performance, particularly in terms of faster charging and longer lifecycles.
CATL has unveiled today Naxtra, its new sodium-ion battery cells, and it claimed some truly impressive specs.
The new cell reportedly achieves an energy density of 175 Wh per kg (385 Wh per lb), on par with the higher-end of LFP battery cells.
The new cells also offer potential for significant safety improvements.
CATL shared several intense stress tests, including drilling into a cell and even cutting it in half without any thermal event:
The next-gen sodium cells could help further lower the cost of electric vehicles without compromising performance, and while increasing safety.
On top of the new Naxtra cell, CATL has also unveiled its next-gen Shenxing LFP battery cells.
Its charge rate is truly impressive. CATL shared several examples of cars charging at around 1,000 kW and maintaining over 500 kW at over 50% state of charge:
The new cell is being described as capable of adding 300 miles (482 km) of range in about 5 minutes – depending on the EV model.
That’s virtually as quick as filling up a tank of gas.
CATL says that the Shenxing will be in 67 electric vehicle models by the end of the year.
The next-gen cell was unveiled after BYD, CATL’s biggest competitor, also unveiled its latest technology, capable of charging electric vehicles at extremely high speeds.
