Great opportunity for e-cars: battery manufacturer celebrates breakthrough
Eureka! One of the biggest challenges for engineers is balancing the weight and range of electric cars. This dilemma could soon be a thing of the past. The world’s largest battery manufacturer, CATL, was able to construct a battery with an energy density that was previously unachieved. This should now even make battery-powered aircraft a reality.
Super Battery: Strong enough for airplanes
Last week, the Chinese battery manufacturer CATL presented one at the Shanghai Auto Show new battery technology presents. The battery should be so powerful that it can even be used in aviation. At the same time, CATL underlines in the press release the safety of the “condensed battery”.
By using biomimetic electrolytes in a condensed state improves cell conductivity. On the one hand, this makes ion transport more efficient and, on the other hand, the microstructure becomes more stable.
The result is light, high-performance batteries that make the most modern models look old: While the latest 4680 batteries from the electric car manufacturer Tesla were able to store between 272 and 296 watt hours per kilogram, the CATL batteries up to 500 Wh/kg. This means that rechargeable batteries can be almost twice as light with the same performance (source: thedriven.io).
Also presented at the auto show in Shanghai: the VW ID. 2all.
Batteries: More than just cathode and anode
This development is the latest in a series of industry advances: sodium ion battery, lithium iron phosphate battery, Qilin battery and 4680 battery to name a few. Batteries have now been developed that an energy density of almost 1200 Wh/kg own. However, many of these projects are still in their infancy and far from actually going into production.
The real surprise from CATL is that the batteries in series production this year should go. This allows you to dream bigger. According to the manufacturer, it is already working on a battery-electric passenger aircraft, but is also talking about the electrification of shipping.
