This research aims to investigate the phenomenon of capacity rising in LiFePO4 batteries and its implications for cell design.
Analyzed data from electric vehicle applications using LiFePO4 batteries
Conducted controlled experiments to observe capacity changes over cycles
Evaluated performance metrics related to safety and durability
Observed significant capacity rising of up to 20% in early charge cycles
Demonstrated the impact of temperature and charge rate on capacity
Highlighted the need for design adjustments to enhance long-term reliability
Abstract
LiFePO 4 (LFP) batteries are widely adopted in electric vehicles due to their low cost, safety, and durability. Many LFP cells exhibit a counterintuitive “capacity rising” in early cycles, yet its...
