Gotion High-Tech’s Astroinno battery claims 1,000 km range without NCM

Chinese battery manufacturer Gotion High-Tech has introduced its lithium manganese iron phosphate (LMFP) based Astroinno L600 battery cell and pack, which it plans to start mass producing in 2024.

Manganese-doped LMFP Astroinno batteries offer a 1,000 km range, over 1,800 cycles of 18-minute fast charging and 190 Wh/kg specific energy, according to the company. Gotion High-Tech uses co-precipitation, doping encapsulation technology, new granulation technology and electrolyte additives to solve the challenges of Mn dissolving at high temperatures, low conductivity and low compaction density.

Astroinno’s simple design and sandwich-structure double-sided liquid cooling technology decrease the battery pack’s number of structural elements and weight by 45% and 32%, respectively, according to the company. Moreover, its electrical design reduces the length of the battery pack wire harness from 303 meters to 80 meters—26% that of previous battery packs—but the volumetric cell-to-pack ratio has reached 76% and the in-house thermal insulation materials can endure 1,200° C.

“The Astroinno L600 LMFP battery cell has a [specific energy] of 240 Wh/kg, an energy density of 525 Wh/L, a cycle life of 4,000 times at room temperature and a cycle life of 1,800 times at high temperatures. It is due to the high energy density that we can enable a range of 1,000 km without relying on NCM materials,” said Dr. Cheng, Executive President of Gotion High-Tech’s International Business Unit.
