- MG has attached to his promises by marking the beginning of the first semi-solid state batteries
- The first indications suggest that it is on sale in China for less than $ 14,000
- SAIC and MG will undoubtedly seek to present technology elsewhere
The Chinese automation manufacturer Saic has revealed that he will present to the first mass electric vehicles in the world to launch worldwide with semi-solid state batteries in the next MG4 after promising technology last year.
Cleaned for sale in China, the high -end MG4 changes a chemistry of lithium iron phosphate (LFP) for dense lithium -ion batteries in energy provided by Qingtaoenergy.
The key difference between a semi -solid state battery and existing LFP chemistry is that the electrolyte extends to horcajadas on the line between a liquid and a solid.
Where the electrolyte in traditional LFP batteries tends to consist of a lithium salt liquid, semi -solid state batteries use a substance similar to a gel.
According to the reports, the new MG4 battery packages have an energy density of 180 °/kg and are expected to have a range of around 333 miles. But MG has not revealed the total battery capacity or exact range figures.
Interestingly, the new battery technology does not offer advance in the range, with cheaper LFP battery options within the model line that offers a similar electrical range.
But a semi -solid chemistry offers advantages in a higher energy density (required lighter and smaller batteries), higher levels of safety thanks to non -flammable electrolytic substance, better longevity and the potential of much faster load speeds.
SAIC says that the MG4 will go on sale in China with prices that begin by less than $ 10,000 and increase to around $ 14,000 for semi -solid battery package models. The model is expected to display global markets, such as Europe, at the beginning of next year.
Affordable progress
While Saic’s battery announcement does not seem to offer a considerable leap in the range, we could see that load times are drastically reduced, while battery packages are promoted to last longer before showing signs of degradation, which helps improve the residual values of cars.
Unfortunately, the true turning point in EV technology will come when complete solid state batteries reach the market, avoiding liquid electrolytes for a solid material, such as metal, ceramics and polymers.
Several renowned automotive brands are already working on technology, with the tastes of Mercedes-Benz promising 450Wh/kg at the cellular level, almost four times that of the recent MG announcement.
These smaller and densest energy packages promise greater loading speeds and the ability to offer an impressive range of the real world without the additional weight, which would allow sports car manufacturers to produce the type of agile and agile walks that performance fans have been crying.
However, it is very likely that Chinese battery manufacturers and automotive brands are the first to take technology to the market.
For now, Saic and MG’s announcement seems to close a gap before true advances occur, but it is still an impressive progress. And progress that does not come with a mental price label.
