Currently available commercial Li-ion batteries do not adequately meet the requirements of electronic appliances, such as cell phones, laptop computers, power tools, sensors, and remote controllers. The cathode materials developed in this program will increase the overall performance of Li-ion batteries used in these applications. Others applications for the materials developed here include Electric vehicles (EV), hybrid electric vehicles, power backups, and alternative power generation, such as solar panels, wind turbines, which need batteries to store the generated energy. Currently, Li-ion batteries are utilized only for low-cycle life space applications, but reliable and safe Li-ion batteries with improved cycle and calendar life, high energy density and good low temperature performance are needed for astronaut equipment and solar powered landers, rovers, propulsion, and human outposts. With NEI's cathode materials, a high performance Li-ion battery will be produced to meet NASA requirements.
