Abstract

The invention relates to a roll-type carbon fiber battery plate. The roll-type carbon fiber battery plate comprises negative lead plaster, second superfine glass fiber, positive lead plaster and first superfine glass fiber which are sequentially arranged from inside to outside, wherein a lead-calcium-tin alloy grid is arranged at the end part of the positive lead plaster, a carbon fiber felt grid is arranged at the end part of the negative lead plaster, a positive tab is arranged on the positive lead plaster, and a negative tab is arranged on the negative lead plaster. The invention also provides a preparation method of the roll-type carbon fiber battery plate. According to the invention, the energy density of a battery can be improved; the welding capacity of a lead belt and the carbon fiber felt grid is improved, and meanwhile the binding force of the carbon fiber felt grid and the lead plaster is improved; problems in the connection mode of the grid and a busbar are solved; the falling of the negative carbon fiber grid and the lead plaster is delayed, and the service life of the battery is prolonged; and the pole shoulder of a negative pole plate is made of special lead-calcium-tin alloy, and the width of the pole shoulder is 3 mm, so the winding forming of a pole group can be improved.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a rolled carbon fiber battery pole plate and a preparation method thereof. Background technique [0002] Improving the energy density of lead-acid batteries has always been one of the problems faced by the research and development of lead-acid batteries. The important reasons are the low utilization rate of lead paste and the high ratio of grid weight to total weight. In order to solve the problem that the weight of the grid is high in the total weight, some researchers use plastic negative grids or conductive fibers, and adopt methods such as tight assembly, but they all face many problems such as poor bonding between the grid and the lead paste. [0003] The main defect of existing scheme is: [0004] The energy density of the battery is low, the carbon fiber grid and busbar are poorly welded, and the grid and lead paste fall off. Contents of the invention [0005] The pu...
