压力对三元锂电池膨胀及充放电性能的影响
Effect of pressure on charge and discharge performance and expansion of ternary lithium battery
摘要
Abstract
The package made of soft package batteries must use the encapsulation structure.The encapsulation pressure and expanding pressure have great influence on batteries performance during charging and discharging.The 50 Ah ternary lithium battery of soft package was tested under constant pressure and constant deformation.The results show during charging and discharging at 0.5 C and under pressure of 0-5 000 N and 3.0-4.2 V,the maximum swell increment of the battery keeps constant for 1.8% of the battery thickness;the battery capacity decreases as the pressure increases;on the condition of constant deformation,the maximum pressure increment is 40%,and the battery capacity decreases as the initial pressure increases.关键词
