Development of Lithium-ion Battery of the “Doped Lithium Iron Phosphate–Doped Lithium Titanate” System for Power Applications

摘要

Lithium-ion battery based on a new electrochemical system with a positive electrode based on composite of doped lithium iron phosphate with carbon (Li0.99Fe0.98Y0.01Ni0.01PO4/C) and a negative electrode based on doped lithium titanate (Li3.812Ti4.972Ga0.1O12) has been developed. The battery is intended for use in fixed energy storage units. The battery is characterized by the ability to operate at increased charging/discharging currents (up to 30 C). Specific power of the battery can reach about 1.5 kW kg-1.
