CATL is Ready to Mass Produce Sodium-Ion Batteries, Range Up to 600 km
In the West, we have come to know the name CATL, a company that now dominates the global sector of batteries for electric cars. Even at home, month after month, CATL sets market share records, which have now surpassed 46%, and could soon increase further thanks to a new technology.
We are talking about sodium-ion batteries, not to be confused with salt batteries. Sodium-ion batteries are accumulators where sodium replaces lithium, taking advantage of sodium's natural abundance, easy availability, and thus low fixed costs, unlike lithium which often suffers from high price volatility.
After an initial phase of testing and study, Wu Kai, the scientific head of CATL and a member of the Chinese Academy of Engineering, confirmed that production bottlenecks have been resolved, and thus the company is ready to move on to a phase of true mass production.
The first versions, as already speculated, will be aimed at budget electric cars, precisely to capitalize on the price factor, but in the meantime, CATL is already working on versions with higher energy density, aiming to at least match LFP chemistry batteries, thus up to about 600 km of range per single charge.
This is a fundamental step, as it complements the Holy Grail of solid-state batteries with a solution that maintains current performance while improving the final cost of the car. And it doesn't stop there, as other solutions, such as lithium-air, are already on the horizon, which will instead work towards weight reduction (effectively using atmospheric air as a reagent, eliminating some components).
CATL, which as mentioned already dominates the sector, will have a product portfolio for every need.
