Preparation method of lithium battery for mobile phone

The invention relates to a preparation method of a lithium battery for a mobile phone. The preparation method comprises steps as follows: 25%-55% of zinc nitrate, 10%-25% of sodium oxide, 25%-75% of lithium carbonate and 30%-85% of carbon dust are mixed in percentage by mass and then put into a heating device, the mixture is heated gradually to be treated at the temperature of 850-1,000 DEG C for 8-12 h, cooled, crushed, ground and sieved, and a battery material is obtained and wrapped with a wrapping layer made from polytetrafluoroethylene. The preparation method has the advantages that the prepared battery is high in safety coefficient, hardly expands once heated and has high safety as explosion danger is eliminated. 本发明涉及种手机用锂电池的制备方法，包括以下步骤：将以下组分按质量比例进行混合：25％-55％硝酸锌、10％-25％氧化纳、25％-75％碳酸锂、30％-85％碳粉，然后放入加热设备中逐渐提高温度至850-1000℃处理8-12小时，冷却后粉碎、研磨、筛选得到电池材料，将电池材料装入由聚四氟乙烯制成的包裹层。本发明的优点是：制得的电池安全系数高，遇热几乎不膨胀，从而消除了爆炸危险，具有高度安全性。
