Shanghai (Gasgoo)- On December 12, GAC AION's Yinpai Intelligent Battery Eco-factory celebrated its official construction completion and commencement of operations, coinciding with the release of the P58 Microcrystal Super Power Battery ("the P58 Battery"), which represents the breakthrough on the Magazine Battery 2.0, according to GAC AION's press release.
As one of the early adopters of electrification and independent power battery development among domestic automakers, GAC Group initiated R&D of battery system and BMS (battery management system) in 2011 with the first independently designed PHEV-dedicated battery pack integrated into the Trumpchi GS4 PHEV in 2015. Then, in 2017, GAC AION produced its first in-house developed BEV-dedicated battery pack, and initiated the independent R&D of power battery cells and construction of a battery cell testing line in the same year. Starting from 2021, GAC AION progressively introduced advanced battery technologies such as the Magazine Battery system safety technology, sponge silicon anode battery technology, and ultra-rapid charging batteries. In 2022, the pilot-scale production line for battery cells was completed and put into operation.
With the completion of the Yinpai Intelligent Battery Eco-factory, GAC AION has officially gained the full-stack capability of in-house R&D and production.
According to GAC AION's introduction, the P58 Battery, overcomes various material and technical challenges, boasting exceptional safety, high energy density, long lifespan, and outstanding fast-charging capabilities.
In terms of safety, the P58 Battery utilizes a highly stable lithium iron phosphate cathode chemical system, a nanoceramic/high-temperature-resistant polymer composite coating membrane, and high-safety electrolyte technology, ensuring no smoke or fire during needle puncture tests and temperature rise less than 1℃. Moreover, it remains effective under high-intensity compression, with a pressure resistance exceeding 1,200 kN and deformation tolerance reaching 45%. Coupled with the Magazine Battery 2.0 technology, it prevents the entire battery pack from catching fire even when shot.
To achieve high energy density, the P58 Battery employs optimized designs such as square stacking and direct welding of the top cover/pole ear. This achieves an internal volume utilization rate exceeding 90%, enabling a range breakthrough of over 700 km on a single charge. It also features the 3C fast-charging capability, providing a 250 km range in just 10-minute charging, alleviating user range anxiety.
Crucially, the P58 Battery significantly enhances lifespan, added GAC AION. Thanks to the application of multi-step film formation and low-consumption lithium-anode technologies, it achieves over 4,000 cycles of fast-charging lifespan at room temperature and over 3,300 cycles at high temperatures. The theoretical total driving distance of the vehicle can exceed 1.5 million kilometers.
