The objective of this proposal is to demonstrate the feasibility of developing advanced battery chemistries that provide batteries operate safely at specific energies higher than 100 Wh/kg, energy densities over 600 Wh/l. The olivine-type phosphate cathodes are attractive. The stable nature of the olivine-type structure having a PO43− polyanion with a strong P–O covalent bond provides not only excellent cycle-life but also a safe system. Further, olivines are resistant to overcharge and thermal degradation, and are inherently safer than oxides that may release oxygen at inopportune times. The robust covalent bonding of PO43−, however, reduces the compounds’ ionic conductivities, and olivines require additional treatment with conductive aids to perform at reasonable capacities. Yardney Technical Products proposes to develop a high voltage (5V) olivine-type phosphate cathode, and a suitable electrolyte system for high energy Li-ion battery.
