We found by the three-electrode experimental cell, deposition of metallic lithium during low-temperature charging is related to electrolyte, charging rate, cut-off voltage and so on.
通过三电极电池研究发现，锂离子电池在低温充电过程中出现的金属锂的沉积与电解液种类、充电倍率和截止电压等因素有关。
When the frequency is higher than the cut-off frequency, as the frequency increases, voltage amplification factor will be reduced, thus the circuit has a "low-pass" characteristics.
当频率高于截止频率时，随着频率的升高，电压放大倍数将降低，由此电路具有“低通”的特性。
