Effect of temperature on the performance of lead-acid batteries

Sep , 18 2023

What are the effects of temperature on the performance of lead-acid batteries? From the chemical reaction equation of lead-acid batteries, PbO2 is on the positive plate, and Pb is on the negative plate. The electrical and physical properties of these two substances vary very little with temperature, so it can be said that the temperature effect of the discharge performance of lead-acid batteries i...

Basic knowledge of maintenance-free lead-acid batteries

Dec , 23 2023

1. Meaning of maintenance-free battery The main advantage of the valve-controlled lead-acid battery is that the oxygen generated on the positive plate during charging is reduced to water on the negative plate through the recombination reaction, and water does not need to be added during the specified floating life period when used, so it is also called maintenance-free lead-acid battery. It can be...

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...

The reason why LiFePO4 batteries cannot be charged but can be discharged below 0℃

Jun , 07 2025

Why LiFePO4 Batteries Cannot Be Charged Below 0°C but Can Still Discharge The reason why LiFePO4 (Lithium Iron Phosphate) batteries, such as the EverExceed battery range, cannot be charged below 0°C yet can still discharge lies mainly in their electrochemical characteristics and safety considerations. 1. Why Charging Is Restricted at Low Temperatures Lithium Plating Risk: At sub-zero temperatures,...

Analysis of the reasons for grounding the -48V positive terminal of the communication base station

Nov , 28 2025

1. Prevention of Electrochemical Corrosion (The Most Critical Reason) Physical Principle: In humid environments, metal conductors carrying a positive voltage (positive pole) are more likely to attract negative ions from the air, leading to electrochemical corrosion and causing cables and terminals to gradually rust and break. System Design: If the positive terminal of the power suppl...
