Common faults of battery

Battery vulcanization: A layer of large white hard crystals is formed on the surface of the negative plate inside the battery, which cannot be peeled off after charging, nor can it be converted into lead sulfate as an active material. This is called irreversible sulfation, or "vulcanization" for short.

Common faults of batteries include internal faults and external faults.

The external faults mainly include shell cracks, pole corrosion, pole looseness, and dry cracking of the sealant; while internal faults mainly include pole plate vulcanization, active material shedding, pole plate grid corrosion, pole plate short circuit, self-discharge, and pole plate arching.

Common causes of sulfation of battery plates

Excessive discharge causes more lead sulfate to be generated in the deep layer of the electrode plate, which agglomerates and adheres to the deep pores of the active material, so that it is not easy for normal charging to fully act on the inner layer of the plate to reduce it.

Common faults and troubleshooting methods of lead-acid batteries

The faults in the use of lead-acid batteries can be divided into external faults and internal faults according to the location.1) External failure: shell crack, pole pile corrosion, pole pile looseness and sealant dry crack.

Solutions to common problems of lead-acid batteries

The temperature rises, the voltage drops; the temperature drops, the voltage rises.Can the battery be used up before charging it?Hurry up and power it is recommended to charge the battery when the battery power is lower than 80% of the rated power storage capacity.

Analysis of the energy density of lithium batteries, how to improve the energy density of lithium batteries?

"Energy density" refers to the amount of energy stored in a unit of a certain space or mass matter. The energy density of a battery is the electric energy released by the average unit volume or mass of the battery. The energy density of a battery is generally divided into two dimensions: weight energy density and volume energy density.

Precautions for the installation of solar batteries

1) The installer (or engineering team) receives the installation task instruction, prepares relevant materials (such as battery installation of various manufacturers, record sheets, etc.) and a full set of installation tools (including multimeters, etc.), and confirms the start date of the project and the progress of the project, etc. .
