China’s GAC reveals “super iron” LFP battery with 20% increase in energy density by volume

While other companies look to experimental solid-state batteries to increase energy density, Chinese automaker GAC is looking to improve on existing lithium iron phosphate (LFP) chemistry.

GAC recently announced a “super iron” LFP battery, which claims to have 20% greater energy density by volume than conventional LFP cells, through microcrystalline technology – achieving high energy density. energy increased by 13.5% at the cellular quality level.

The battery was announced alongside a number of other technology and media features at the company’s GAC Technology Day 2022 and was only briefly mentioned in that presentation.

The company also revealed a prototype hydrogen combustion engine announced late last year. According to GAC, the 1.5-liter engine burns 0.84 kilograms of hydrogen per 100 kilometers. However, it is still unclear whether this engine will enter production or not. And it’s unlikely that it will reach the US if it does.

To refresh, GAC planned a US launch, but a few years ago focused more on its domestic market and cooperation with Nio for EV development. GAC currently sells electric vehicles in China under the Aion brand, along with a variety of internal combustion models of many brands.

Before that, it brought several vehicles to the Detroit Auto Show in 2017 and 2019. Among the promising products was the Entranze, a Electric minivans look futuristic Concept announced in 2019.

Chinese automakers and battery manufacturers are accepting LFP batteries more quickly than companies in other regions, but LFP chemistry is no longer the only area for automakers in the market. Chinese school. Tesla used LFP cells in a number of vehicles manufactured and sold in the United States, and Rivian as well as the plan.
