In liquid, then sequentially make airing, drying, baking and cooling treatment.
Scheme as a further improvement, the carbon fiber felt integrally soak in the solution, and the solution is contains 3~10%
Plumbi nitras aqueous solution, soaking time for 2~for 24 hours.
Scheme as a further improvement, the soak carbon fibre felt, which finishes, to be pulled out, and the airing under normal temperature condition is pulled out
Carbon fiber felt is sent into carbide furnace again afterwards and is dried, 100~140 DEG C of drying temperature, drying time 4~for 24 hours, then still same
It toasts in one carbide furnace, when baking introduces nitrogen in carbide furnace, and furnace temperature is fast by 50~150 DEG C/h after rising to 500~600 DEG C
Degree heating stops heating, but nitrogen still sustainable supply when furnace temperature rises to 1500~1600 DEG C, until furnace temperature is down to 100 DEG C
When stop nitrogen input.
Compared with prior art, the present invention it has the positive effect that：
1st, technical process is simple, and it is easy to implement；
2nd, the lead plating on carbon fiber felt, lead layer are improved between carbon fiber felt and active material using the excellent adhesion of lead
The bond quality of carbon fiber felt and active material, so as to further improve mating carbon fiber battery charge acceptance, after electric discharge
Higher state-of-charge can be quickly recovered to.On the other hand because active material and carbon fibre felt faying face are closely knit, active material is by sulphur
The speed of hydrochlorate significantly slows down, and will not come off without reason in use, so the recycling longevity of mating carbon fiber battery can be improved
More than 10% life.
