Cycle Life Prediction Method of Lithium Batteries Based on Morphology and Properties

1929年诺贝尔物理学奖授予法国物理学家德布罗意（de Broglie,1892-1987）,表彰他提出电子具有波动性及德布罗意关系式.1923年,德布罗意从已揭示的原子物理现象中看到了电子与光量子的某些类比性,並进而提出假设：既然光有二象性（在光电效应中有典型的表现）,那么,电子不仅具有粒子性（已知）,是否也应有波动性。

Abstract ： The conventional prediction model for cycle life of lithium power batteries may generate prediction error, because it ignores the impact of the structural changes caused by electrochemical reactions. To solve this problem, the lithium iron phosphate batteries are regarded as the research objects for the study of the relationship between the internal structure and the cycle life of lithium power battery. The prediction method based on morehology and electrochemical properties is proposed. And a prediction model for cycle life of power barrel7- （ BLPC model） is estab- lished on the basis of the morphology and electrochemical properties. The COlTesponding power battery cycle life test system （BLPC system） is designed to cary out the cycle life experiment of the lithium iron phosphate batteries and verify the validity of BLPC model. The experimental results show that the new prediction method is more reliable and practical than those conventional ones.
