We all use and take for granted the benefits of lithium-ion energy storage solutions in our cell phones, notebooks, PDA's, consumer appliances and other devices. Recent recalls by the US Consumer Protection Commission have brought to light the potential hazards of lithium-ion batteries. Imagine what could happen to a large lithium-ion battery if an electric/hybrid electric vehicle were rear-ended or a manufacturing defect or other abuse caused a thermal event in a mission critical telecom backup system. The results could be devastating.
Valence is a leader in the development and commercialization of phosphate technology, the only safe lithium-ion rechargeable battery technology for large format cells.
The choice of cathode material used in a lithium ion battery has a profound effect on the battery's safety behavior under abuse conditions. The thermal stability of the cathode material is directly related to the degree to which it liberates oxygen at higher temperatures. Valence's lithium phosphate cathode material - using Saphion® Technology - is safer than transition metal oxide cathode materials, particularly lithium cobalt oxide which is commonly used in laptop computer batteries.
