Geely has unveiled its latest innovation in electric vehicle battery technology with the introduction of the ‘Aegis Short Blade Battery’. This new generation of LFP (lithium iron phosphate) batteries, known for their distinctive blade-like design, is set to debut in the Galaxy E5, a newly unveiled five-door electric SUV.
The ‘Short Blade Battery’ represents a significant advancement in battery design, featuring a unique cell-to-pack integration that enhances energy density at the pack level.
According to Geely, the battery addresses issues of high internal resistance typical in long-blade batteries by utilizing long, thin carbon nanotubes for efficient ion transfer and incorporating additives to improve permeability, thus enabling better fast-charging capabilities.
Geely claims the ‘Aegis Short Blade Battery’ achieves an impressive energy density of 192 Wh/kg, supports an average charging rate of 2.45C, and boasts a service life of 3,500 cycles without significant capacity loss. Notably, it offers a rapid charging time from 10% to 80% in just 17 minutes and 4 seconds.
The Chinese automaker highlights improvements over traditional blade batteries, asserting that the new technology delivers faster charging speeds and greater cold weather performance, contributing to extended driving ranges.
In terms of safety, the battery incorporates a high-strength, thermally stable diaphragm and stable separator alongside secure electrodes.
