Description
Technical field
The present invention relates to lead accumulator field, and in particular to a kind of positive electode of lead battery lead plaster.
Background technology
Heavy-current discharge performance is the important parameter of automotive lead-acid battery under low temperature.It is right with the raising of automotive performance
The requirement of lead-acid battery low-temperature high-current discharge performance also more and more higher.
The reason for influenceing automobile using lead battery cold-start performance is mainly internal resistance of cell increase under low temperature, and electrolysis fluid viscosity increases
Greatly, SO4 2-Ion diffusion is difficult, in addition, consuming SO during heavy-current discharge4 2-Speed quickly, SO needed for reaction in pole plate4 2-Amount
It cannot supply in time.Make for the influence calcium alloy of lead additive and electrode plate structure to lead-acid accumulator cold-start performance positive and negative
The maintenance-free battery of grid also exist one between inscribe, i.e., using a period of time after, impedance is increasingly generated between grid and lead plaster
Big barrier layer, the cold-start performance of battery life middle and later periods is set drastically to decline.The major measure for improving cold-start performance is to subtract
Baby battery internal resistance, increase acid content in pole plate lead plaster.
The content of the invention
The present invention is in order to overcome drawbacks described above present in prior art, there is provided one kind can reduce the internal resistance of cell, increase
Add the positive electode of lead battery lead plaster of acid content in pole plate lead plaster.
