手机电池电容量下降曲线研究 摘 要：本文进行了对手机电池电容量下降曲线的实验，研究了电压和电流对手机电池性能的影响。运用了传统的试验方法，将正常与损坏的容量为1800锂离子电池的放电实验现象进行了研究。根据电池电容量的两个参照指标电压和电流与时间的变化关系，得出了正常的手机电池电容量下降曲线先平缓然后快速下降；损坏的手机电池电容量曲线呈快速下降趋势，并且在电流及电压两方面影响手机通话质量以及手机的正常运行。

Research on Mobile Phone Battery Capacity Decline Curve
Abstract: This paper has carried on the mobile phone battery capacity decline curve experiment, studies the influence of voltage and current on the mobile phone battery performance. Using the traditional method, the normal and damaged capacity of 1800lithium-ion battery discharge experimental phenomena were studied. According to the two changes of reference index of voltage and current with time between mobile phone battery capacity, the mobile phone battery capacity normal decline curve even then declines rapidly; mobile phone battery capacity curve damage decreased rapidly, and influence the normal operation of mobile phone and mobile phone call quality in two aspects of current and voltage.
