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...

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...

From Inconsistency to Reliability: EverExceed’s Lithium Battery Solutions

Aug , 16 2025

Why Inconsistency Happens Lithium iron phosphate (LiFePO₄) battery packs naturally face inconsistency challenges over time. Manufacturing differences: Even with strict process control, slight variations in materials and production steps lead to differences between cells. Usage environment: Temperature, ventilation, and charging/discharging conditions accelerate these differences during operation. ...

EverExceed | Understanding SOH (State of Health) in LiFePO₄ Batteries

Nov , 14 2025

SOH (State of Health) is a key indicator used to evaluate the current performance of a battery compared with its original, brand-new state. It is usually expressed as a percentage: 100% SOH = brand-new battery 70–80% SOH = typical end-of-life threshold For EverExceed LiFePO₄ batteries—widely used in UPS, telecom, data centers, marine systems, and energy-storage applications—accur...
