摘要：

The relationship between cutoff charge-voltage and lithium-ion battery performance is very complex. This paper explores the influence of cutoff charge-voltage on lithium manganite (LMO)/lithium titanate (LTO) power lithium-ion battery for power application performance. Performance criteria evaluated include: low-temperature discharge capacity, pulse power density, and high temperature cycle life. Results illustrate that a lower cutoff charge-voltage (3.0 V) resulted in a battery with high discharge capacity at low temperature while a higher cutoff charge-voltage (3.8 V) in a battery leads to good high temperature cycle stability. A moderate cutoff charge-voltage (3.4 V) brought a battery with both high and low temperature-enhanced performance.
