Chinese giant Geely has unveiled its new LFP battery cell, featuring 192 Wh/kg energy density, a 50-year service life, rapid charging to 80% in under 20 minutes, and minimal capacity loss in cold weather.
This technology, akin to iron phosphate batteries used in Tesla’s base Model 3 and popular power stations like the Anker SOLIX F1200, addresses various concerns about electric cars beyond their price.
The battery excels with 3,500 charge cycles, equivalent to about a million kilometers, surpassing the high internal resistance of long blade batteries supplied by BYD to Tesla.
The Chinese company also added that its LFP battery promises significant benefits for the used electric car market, as EVs could maintain performance over more than 600,000 miles with minimal capacity loss. This durability equates to approximately 50 years of service life, considering average annual driving distances.
Moreover, Geely’s adoption of carbon nanotubes and enhanced cover film accelerates the movement of lithium ions, achieving an impressive charging time of just 17 minutes to bring the battery from 10% to 80% capacity.
Due to improved ion transfer, Geely’s Aegis Short Blade Battery experiences only a 10% range loss in extremely cold conditions, matching CATL’s fast-charging LFP cell introduced last year.
Interestingly, CATL, the world’s largest battery maker, is pursuing EV batteries capable of lasting a million miles. They have partnered with NIO to offer 15-year warranties on EVs.
Geely will initially deploy its new LFP cells in Galaxy E5 SUVs before making them available to other customers. To guarantee the durability of the short-blade LFP battery, Geely subjected it to rigorous tests: exposure to open flames, puncturing with nails, rolling over, submersion in corrosive seawater, and operation in freezing conditions.
According to the company, the thermally resistant separator and self-healing electrode technology passed all durability tests with flying colors, paving the way for EVs with a 50-year battery service life.
Meanwhile, GAC Toyota’s upcoming Bozhi 3X SUV will be the first EV to feature self-driving tech, marking an exciting development. Toyota has also committed to updating its current EV lineup, with the bZ4X electric crossover set for enhancements between 2026 and 2027.
As part of this launch, Toyota will also introduce an autonomous driving system capable of navigating highways, urban settings, and providing parking assistance.
Additionally, Toyota is developing an LiFePO4 EV battery that could potentially reduce the production cost of the bZ4X by up to 40%. Whether these savings will be passed on to consumers remains uncertain, but it highlights Toyota’s renewed commitment to advancing EV technology.
