摘要：

Uniform lithium iron phosphate nanoplates with a thickness of 30 nm, width of 100 nm, and length of 200 nm are synthesized by a solvothermal method. Electrochemical measurements show that the nanoplates exhibit low polarization and reach a discharge capacity of 165 mAh g(-1) at 0.1 C, 140 mAh g(-1) at 5 C.
