Method of preparing carbon nanotube-olivine type lithium manganese phosphate composites and lithium secondary battery using the same |
摘要 |
Provided are a method of preparing carbon nanotube-olivine type lithium manganese phosphate composites and a lithium secondary battery using the same. The method includes acid-treating a carbon nanotube to purify the carbon nanotube by adding an acid solution to the carbon nanotube, forming a precursor mixture of the carbon nanotube and a metal precursor of olivine type lithium manganese phosphate, and heat-treating the precursor mixture. The carbon nanotube-olivine type lithium manganese phosphate composites can provide high energy density per unit volume and can improve output characteristics. |
