Embodiment

[0013] Embodiment: the winding type grid fiber composite wire in this scheme, such as figure 1 As shown, it includes synthetic wires and copper wires 2. The components of the synthetic wires include lead-free glass and porous carbon;

[0014] The compound wire manufacturing method in this scheme comprises the following steps:

[0015] Step 1: Preparation of lead-free glass powder

[0016] The formula composition of lead-free glass powder: proportioning by mass fraction, B 2 o 3 2%, Bi 2 o 3 3%, ZnO 3%, Al 2 o 3 is 2%, MgO is 2.5%, BaO is 7.5%, and the balance is SiO 2 .

[0017] Add the above ingredients into the ceramic crucible in batches, and when the temperature of the box-type sintering furnace rises to 1250°C, put the ceramic crucible into the sintering furnace. Mill in a ball mill jar for 72 hours, and sieve through a 400-mesh sieve to obtain glass powder with an average particle size of 3 μm, and obtain lead-free glass powder with a softening point of 800°C. ...

Abstract

The invention belongs to the field of a grid of a battery pole plate, and particularly discloses a winding type grid fiber composite line. The winding type grid fiber composite line comprises a synthesis line and a copper wire, wherein the constituent of the synthesis line comprises lead-free glass and porous carbon, the synthesis line comprises a plurality of winding lines and a connection line,the plurality of winding lines are wound around the copper wire, the connection line is used for connecting a winding part, and the glass comprises the constituent based on percent by mass: 2-5% of B2O3, 2-3% of Bi2O3, 2-3% of ZnO, 2-5% of Al2O3, 2.5% of MgO and 7.5% of BaO with the balance being SiO2. The glass is contained, the strength of the composite line is ensured by the continuously-connected synthesis line, so that the strength of the grid is ensured, an outer frame can be omitted, and the quality of the grid is further reduced.

Description

technical field [0001] The invention belongs to the field of grids of battery pole plates, and in particular relates to a grid composite wire. Background technique [0002] In recent years, the electric vehicle industry has developed rapidly, and the corresponding demand for batteries has also surged. Various battery manufacturers have increased investment in electric vehicle batteries, which has made battery companies more competitive in price and reduced profits. How to improve battery quality and reduce battery cost is in front of enterprises. The grid mainly plays the role of supporting the active material and conducting electricity in the battery, but does not react itself to provide electric energy. At present, most of the negative plate grids of lead-acid batteries use lead-tin or lead-calcium-tin alloy, which is relatively expensive. Therefore, it is possible to find a light and cheap material to replace the current grid alloy, which will increase the specific energ...
