GUANGZHOU, China, July 1, 2022 /PRNewswire/ --...
GAC GROUP also launched its new-generation super iron lithium battery built on microcrystalline technology (SmLFP), which provides batteries with 13.5% higher cell quality energy density and 20% greater volume energy density than regular mass-produced iron phosphate lithium battery cells available on the market.
Aside from the SmLFP technology, GAC Group introduced its Mega Waves Hybrid Modular Architecture and unveiled its 1.5L hydrogen-fueled engine for the first time. The hydrogen engine features a hydrogen consumption of 0.84kg/100km. Both technologies will serve as key solutions in the company's efforts to reach carbon neutrality.

Not only that, but the improved design and chemistry allow for about a million miles of service life, again a particular increase of the current LFP battery longevity. Last but not least, the battery capacity retention at sub-zero temperatures gets another 10% boost in direct comparison with the conventional LFP batteries used currently in electric cars.
At the moment, Tesla is positioned very well to take advantage of the low cost, low energy density characteristics of LFP cells as its drivetrain is extremely efficient and can achieve decent range numbers with the cheaper batteries. With the progression of the lithium iron battery tech, however, like GAC's new SmLFP invention, its utilization is bound to become more ubiquitous.

GAC said that SmLFP consists of LFP batteries“built on microcrystalline technology,” which does not really explain what changed. Thanks to that mysterious solution, the SmLFP cells have “13.5% higher cell quality energy density and 20% greater volume energy density than regular mass-produced” LFP cells. We have no idea what the Chinese automaker means by “higher cell quality energy density.” Volume energy density refers to the proportion of Wh per liter instead of Wh per kg.
In March, SVolt disclosed that it was producing LFP cells with an energy density of 200 Wh/kg. If GAC’s LFP batteries are at the same level and the “higher cell quality energy density” refers to Wh/kg, the SmLFP cells could offer 227 Wh/kg. That’s on par with what Gotion High-Tech and SVolt said they could achieve: 230 Wh/kg.
GAC also said that these new SmLFP cells stand 2C of quick charge and have a lifespan of 1.5 million kilometers (932,056 miles). GAC also tweeted something else we cannot understand: “10% capacity at the -20°C low temperature.” Is it 10% more capacity in these conditions? Only 10% of its original capacity? We honestly don’t know, and Chinese companies, in general, are not reachable for comments. GAC is no exception.
