- MG has kept to his promises by initiating the first half -stated state batteries
- Early indications suggest it is for sale in China for less than $ 14,000
- Saic and MG will undoubtedly look at introducing the technique elsewhere
Chinese carmaker Saic has revealed that it will introduce the world’s first mass -produced EVs to launch globally with semi -fasted state batteries in the upcoming MG4 after promising technology last year.
Cleared for sale in China, the range MG4 swaps a lithium jernphosphate (LFP) chemistry for more energy-tight manganese-based lithium-ion batteries provided by Qingtaoenergy.
The most important difference between a half-solid state battery and the existing LFP chemistry is that the electrolyte extends across the line between a liquid and a solid.
Where the electrolyte in traditional LFP batteries tends to consist of a lithium salt fluid, semi-solid state batteries use a gel-like substance.
According to reports, the new MG4 battery packages have an energy density of 180Wh/kg and are expected to have a range of about 333 miles. But MG has not revealed the full capacity of the battery or accurate range.
Interestingly, the new battery technology does not deliver a breakthrough within easy reach, where the cheaper LFP battery settings within the model setting offer a similar electrical interval.
However, a semi-solid chemistry provides benefits in greater energy density (lighter and smaller battery packs required), increased safety levels thanks to the non-named electrolyte, improved life and potential for much faster charging speeds.
SAIC says MG4 will be sold in China with prices starting at less than $ 10,000 and rising to about $ 14,000 to the half -made state battery models. The model is expected to roll out to the global markets, such as Europe, early next year.
Affordable progress
While SAIC’s battery notification does not appear to deliver a significant jump within easy reach, we could see charging times reduced drastically, while the battery packs themselves are touted to last longer before showing signs of degradation, which helps improve the remaining values for cars.
Unfortunately, the real turning point in EV technology comes when full solid batteries come on the market and avoid liquid electrolytes for a solid material such as metal, ceramics and polymers.
A number of large name Automotive Brands is already working on the technology, just as Mercedes-Benz promised 450Wh/kg at the cell level-almost four times it for MG’s recent announcement.
These smaller, more energy -tight packages promise greater charging speeds and the ability to offer an impressive range in the real world without the extra weight, which would allow sports car manufacturers to produce the kind of lithe, supple rides that Performance fans have cried for.
However, it is very likely that Chinese battery manufacturers and car brands will be the first to bring the technology to the market.
Currently, Saic and MG’s announcement appear to bridge a hole before the real breakthroughs happen, but it is still impressive progress. And progress that does not come with an eye -watering price tag.
