Geely has unveiled its new lithium iron phosphate (LFP) battery cell, boasting an impressive energy density of 192 Wh/kg, a 50-year service life, rapid charging capabilities, and minimal capacity loss in cold weather. This new battery technology aims to address various concerns about electric vehicles (EVs) beyond their initial cost.
Key Features of Geely’s New LFP Battery:
- Energy Density and Longevity:
- Energy Density: 192 Wh/kg.
- Service Life: 50 years with 3,500 charge cycles, equating to about a million kilometres.
- Rapid Charging:
- Charging Speed: Charges to 80% capacity in under 20 minutes, specifically achieving 10% to 80% charge in just 17 minutes.
- Technological Enhancements: Utilises carbon nanotubes and an enhanced cover film to accelerate lithium ion movement, contributing to faster charging times.
- Cold Weather Performance:
- Minimal Range Loss: Experiences only a 10% range loss in extremely cold conditions, comparable to CATL’s fast-charging LFP cell introduced last year.
- Durability and Safety:
- Rigorous Testing: Subjected to harsh conditions including exposure to open flames, puncturing, rolling over, submersion in corrosive seawater, and operation in freezing environments.
- Technological Innovations: Features a thermally resistant separator and self-healing electrode technology that passed all durability tests, ensuring robust performance and safety.
