Irreversible lithium evolution of LiFePO4 batteries at low temperatures and its effect on battery performance degradation

Dec , 07 2024

Lithium evolution is the main failure problem faced by lithium-ion batteries during low temperature charging. Due to the low diffusion rate of lithium ions in the solid phase of graphite particles and in the liquid phase of the electrolyte at low temperatures, the negative polarization increases during charging and lithium evolution occurs, and the precipitated lithium metal is divided into revers...

Causes of harmonics in rectifier equipment

Mar , 21 2025

1. Nonlinear characteristics The diodes, thyristors and other power electronic devices in rectifier equipment have nonlinear voltammetry characteristics. Take the diode as an example, when the input AC voltage is in positive half circle, the diode is positive and the current can pass through; At the negative half cycle, the diode is reversed off and the current is almost zero. This characte...

Advantages of lead-acid colloidal batteries

Mar , 28 2025

1. Long service life: The colloidal electrolyte can form a solid protective layer on the plate, reduce the bending and short circuit of the plate when used under heavy load, delay the softening and shedding of the plate, and make the battery life reach 1.5-2 times that of ordinary lead-acid batteries. 2. High safety: The electrolyte is solid, sealed, and never leaks. There is no acid mist gas prec...

Why battery calibration?

Apr , 03 2025

Definition of Battery Calibration Battery calibration refers to the process of resetting and synchronizing the battery's power management system with the device's software to accurately gauge the battery's charge level and capacity. This procedure involves fully charging the battery, allowing it to drain completely, and then recharging it to recalibrate the device's battery indicator to provide ac...
