By a News Reporter-Staff News Editor at Chemicals & Chemistry -- Fresh data on Electrochemical Research are presented in a new report. According to news reporting originating from Jiangsu, People’s Republic of China, by VerticalNews correspondents, research stated, “Potassium-ion batteries are attracting great attention as a promising alternative to lithium-ion batteries due to the abundance and low price of potassium. Herein, the phosphorus/carbon composite, obtained by a simple ball milling of 20 wt% commercial red phosphorus and 80 wt% graphite, is studied as a novel anode for potassium ion batteries.”
Financial supporters for this research include National Natural Science Foundation of China, Fundamental Research Funds for the Central Universities.
Our news editors obtained a quote from the research from the China University of Mining and Technology, “Considering the high theoretical specific capacity of phosphorus and formation of stable phosphorus-carbon bond, which can alleviate the volume expansion efficiently, the phosphorus/carbon composite exhibits a high charge capacity of 323.5 mA h g(-1) after 50 cycles at a current density of 50 mA g-1 with moderate rate capability and cycling stability. By the X-ray diffraction analysis, the alloying-dealloying mechanism of phosphorus is proposed to form a KP phase.”
According to the news editors, the research concluded: “Meanwhile, prepotassiation treatment is conducted to improve the low initial coulomb efficiency.”
