每周分享：facile preparation of porous lifepo4/c composite granules by mechanical process-云海官网

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.
