Many cathode materials for lithium batteries consist of large particles that are homogenous in size due to current synthesis methods for LiFePO4 (LFP) particles. These homogenized LFP particles in the lithium batteries cause stress concentrators that degrade the mechanical properties of the LFP particles during charging and discharging. This continuous charging and discharging of the LFP particles in the battery leads to cracking and eventually failure of the cathodes. Further using larger cathodes from the current synthesis methods can lead to extremely long charge times which renders the lithium battery impractical. The University of California is actively seeking licensing partnerships for this technology. A PCT patent application has been filed for this technology.
Cheaper and more efficient lithium batteries could revolutionize the entire industry. This new technology could improve the lithium batteries in your hybrid/electric car your tablet computer or you cell phone and allow them to run for days without charge.
