Abstract

PURPOSE:To improve the charging performance of a leakage-less closed type battery by putting a piece of paper made of carbon fiber in contact with the surface of electrode plates made of an active material mixed with short carbon fiber so as to assemble them together with a mat body impregnated with an electrolyte. CONSTITUTION:Short carbon fiber of 0.3% against the paste weight is added to the paste for a positive electrode and a negative electrode, then they are kenaded and filled into substrates, and after aging, formation, washing and drying, a positive electrode plate 2 and a negative electrode plate 3 are formed. Paper- like carbon fiber 1 of 0.3mm. with a weight of 15gr/cm<3> is put in contact with the surface, and they are assembled together with mat-like glass fiber 4 impregnated with an electrolyte to form a leakage-less closed type lead battery. Therefore, an internal resistance can be reduced due to the short carbon fiber added in the paste and the paper-like carbon fiber put in contact with the surface of electrode plates, thereby the charging performance can be remarkably improved.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a leak-free sealed lead acid battery.

Conventionally, this type of lead-acid battery uses Pb or Pb-C for the positive and negative electrodes.
A substrate made of m-alloy is used, and a mat made of glass fibers with a narrow diameter is used as a separator between the positive and negative electrodes.

Since the electrolyte is occluded in the glass fiber mat and battery active material in a constant amount, there is no need to worry about leakage regardless of the condition of the battery. (tS ~ 1.4) because the amount of electrolyte is reduced,
It has the disadvantage that it is difficult to recharge if left in a deeply discharged state.

Various reasons for this have been considered, but the Pb3O4 shape formed on the surfaces of the positive and negative electrode active materials due to discharge becomes a very dense shape due to the high specific gravity of the electrolyte, and the electrical resistance tends to become very large. The discharge form at the lattice-active material interface in the positive electrode plate is unique to Cm alloys and occurs intensively from the vicinity of the lattice, so in order to further increase the electrical resistance of the dense Pb80° layer near the current collector, In charging,
It is believed that these resistive coatings reduce chargeability.

According to a conventional method, when the positive and negative electrode pastes were mixed together, short carbon fibers having an average fiber length of 3 m and an average single fiber diameter of 1λ5 μm were added and kneaded in an amount of o or a % based on the weight of the positive and negative electrode pastes. After kneading, the paste was filled into each substrate, followed by aging, chemical conversion, washing with water, and drying according to conventional methods. After that, as shown in FIG.
Song, weight isogr/c++! The paper-like carbon fibers 1 were brought into contact with each surface of the positive electrode plate 2 and the negative electrode plate 3, and assembled together with the mat-like glass fibers 4. The battery has a 1 hour rate capacity I

The product of the present invention also has improved discharge capacity, and the utilization rate of the active material is brought into contact with the short carbon fibers added to the paste and the surface of the electrode plate.
This is thought to be because the paper-like carbon fibers improved conductivity and acted as a current collector.

The reason for this is that when left undisturbed after overdischarging, the internal resistance of the conventional product increased by 6 to about 3000 due to the formation of discharge products, PBSO, and a decrease in the specific gravity of the electrolyte, whereas this product The invented product has a low battery internal resistance of about 30 cm compared to the conventional product, so it has improved charging performance by constant voltage charging. It is thought that carbon fiber has the effect of lowering internal resistance.
