Abstract

The invention relates to a preparation method of a lithium ion battery for a high-security mobile phone. The lithium ion battery comprises the following components in parts by weight: 1-5 part(s) of iron phosphate, 1-5 part(s) of magnesium oxide, 1-5 part(s) of lithium carbonate, 1-5 part(s) of lithium ferric pyrophosphate, 1-5 part(s) of Li5La3Ta2012, 10-15 parts of polyacrylamide and 10-15 parts of carbon powder. The preparation method comprises the following steps of: uniformly mixing the components in parts by weight; then processing a mixture in roasting equipment, the temperature of which is gradually enhanced to 800-900 DEG C, for 3-5 hours; crashing, porphyrizing and sieving the materials which are cooled, thus obtaining a battery material; and placing the battery material in a coating layer made from polytetrafluoroethylene. The battery prepared by the method nearly does not expand when being heated, so that an explosion risk can be removed, and the security of the lithium ion battery is high.
