Painting includes internal active material filling and the two-sided painting of surface reactive material, and when internal active material is filled, grid is immersed into activity
In material slurries, active material is set to enter inside fibrofelt using ultrasonic activation, then carry out table after the dehydration of flash baking part
The two-sided painting of face paste active material.
Further scheme is：The conductive carbon fibre felt uses but is not limited to polypropylene nitrile organic material felt carbonization system
, conductive carbon fibre felt grammes per square metre is 100~150g/ ㎡ .mm；The polypropylene nitrile organic material felt uses but is not limited to poly- third
Alkene nitrile chopped strand is made by nonwoven process；Lug on the metal rib and grid of the grid using terne metal,
Pb-Ca-Sn-Al alloy or other metals；The conductive carbon fibre felt is cut into after using electric resistance welding soldering with metal rib
Type；Internal active material is mainly made up of deionized water, lead powder, and surface reactive material is mainly by deionized water, lead powder, dilute sulphur
Acid, bridging agent, swelling agent composition；Flash baking after internal active material filling is by 100~180 in 20~30 minutes

Negative plate is made in cutting, solidification, dry, polishing operation.
In the present invention, the metal rib of traditional grid is substituted by conductive carbon fibre felt part, both soldering are integral, make
After the thickness of original metal rib, thickness and density accordingly reduce, consumption of lead is small, grid weight saving, and intensity, rigidity
Not reducing even strengthens.The polypropylene nitrile chopped fiber or other carbon fibers that the conductive carbon fibre felt is interweaved by countless windings
It is made, its manufacture craft and preferred parameter can guarantee that the intensity of grid, rigidity requirement, by ultrasonic activation, inside fill out active matter
Matter is combined together with above-mentioned fibre compact, and apart from close, contact area is big.During battery charging and discharging, metal rib is fine with carbon
Between dimension, contact resistance is small between carbon fiber and active material, and active material charging is kept well, and negative pole sulfation obtains gram
Clothes, then improve battery.The reduction of grid consumption of lead is advantageous to environmental protection.The preparation method technique of the present invention is complete
It is kind, working specification, industrialized production can be realized, advantageously reduce the stabilization of cost and product quality.
