Safety of Lithium-Ion batteries

Aug , 08 2022

Lithium-Ion refers to a family of Lithium-based battery technology. This family includes several sub-families or technologies, such as: ·LCO: Lithium Cobalt Oxide ·NCA: Nickel Cobalt Aluminium ·NMC: Nickel Manganese Cobalt ·LiFePO4 or LFP: Lithium Iron Phosphate ·LTO: Lithium Titanate Oxide, etc… Often, we can hear that a product is equipped with “Lithium-Ion” batteries; this does not really have ...

Effect of electrolyte on SEI film

Sep , 05 2022

The electrolyte is the main source of the reduction reaction reactants for the formation of the SEI film , and both the electrolyte solvent and the lithium salt will affect the composition of the SEI film. When the main components of the electrolyte are basically fixed, the performance of the SEI membrane can only be improved by other means. The researchers found that the formation of the SEI film...

Failure causes of lithium battery- Failure during shelving

Oct , 08 2022

In the service life of the power battery, most of the time is in a state of shelving. Generally, after a long period of shelving, the performance of the battery will decline, generally showing an increase in internal resistance, a decrease in voltage, and a decrease in discharge capacity. There are many factors that cause the degradation of battery performance, among which temperature, state of ch...

Failure causes of lithium battery- Failure during charging and discharging

Oct , 08 2022

The battery is often overcharged in the process of use. Relatively speaking, the overdischarge situation is less. The heat released during the overcharge or overdischarge process is easy to accumulate inside the battery, which will further increase the battery temperature. , affecting the service life of the battery and increasing the possibility of the battery catching fire or exploding. Even und...

Lithium-ion battery terms explained

Aug , 18 2023

I. Battery voltage (V) 1. Open circuit voltage (OCV) The voltage of the lithium battery when it is not connected to an external circuit or load can generally be tested with a multimeter. 2. Operating voltage (WV) The potential difference between the positive and negative terminals of the battery under applied load, that is, when there is current flowing through the battery in the circuit. When the...

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...
