Abstract:

Using cornstalk core as the carbon source, anode materials P/C with different micro-nano structures were directly synthesized by the deposition method synthesis method. The results show that the CP2[m(P)∶m(C)=4.5∶5.5] assembled lithium-ion battery performed well: the charge capacity of CP2 is 1215.5 mA·h/g at 0.1C(25 ℃), and the reversible capacity is 847.7 mA·h/g after 100 cycles. High- and low-temperature performances were discussed at 0.1C. The results show that the specific capacity of the sample reaches 425.6 mA·h/g at -20 ℃ and 1812.3 mA·h/g at 55 ℃, respectively. An appropriate amount of P distributes uniformly in pores of conductive carbon substrate, so that the lithium-ion battery assembled of this composite show excellent electrical performance.
