今天给大家分享的是2015年4月份 《Materials Chemistry and Physics》上发表的一篇名为:Facile preparation of porous LiFePO4/C composite granules by mechanical process文章摘要如下:
Lithium iron phosphate (LiFePO4) which is a promising cathode material for lithium-ion batteries requires particle size reduction, carbon coating and granulation to improve its electrochemical performances and increase the energy densities. In addition, their composite granules desire a porous structure in order to assist the penetration of liquid electrolyte. Here, we report a facile preparation of porous LiFePO4/C composite granules by a mechanical method using an attrition-type mill. By the mechanical treatment of starting materials, LiFePO4/C composite granules with an average pore size of 20–30 nm were synthesized in one-step process without atmosphere control and external heating. This simple mechanical technique does not require additional pore forming agents. According to the cell tests, a favorable cycle performance was exhibited.
