Abstract

The invention discloses a novel storage battery wiring terminal and a manufacturing method thereof. A base material of the wiring terminal is 6xxx series aluminum alloy. The 6xxx series aluminum alloyis composed of the following components in percentage by mass: 0.5-1.3 wt% of Mg, 0.2-1.3 wt% of Si, 0.2-0.5 wt% of Fe, 0.3-0.7 wt% of Cu, 0.2-0.4 wt% of Mn, 0.1-0.2 wt% of Cr, 0.03-0.12 wt% of Ti, less than or equal to 0.1 wt% of other impurity elements and the balance of Al. -The 6xxx series aluminum alloy material is adopted to manufacture the storage battery wiring terminal, so that the terminal has better conductivity, heat dissipation performance, mechanical strength, appearance and corrosion resistance, meets related standard requirements of storage batteries, and can replace a lead alloy terminal and a copper silver-plated terminal.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a novel battery terminal and a manufacturing method thereof. Background technique [0002] After long-term development, lead-acid batteries have mature and stable technology, safe and reliable performance, and low market prices, and are still widely used in various fields. The positive and negative terminals are important parts for connecting the battery to the external conductor, and require good electrical conductivity, heat dissipation, mechanical strength, appearance and corrosion resistance. In order to improve the power supply efficiency of the battery and reduce the feed voltage drop of the working circuit, the material and structure of the terminal should also be optimized and improved. [0003] At present, the terminals of lead-acid batteries are mainly divided into two categories: lead alloy and copper-plated silver. The lead alloy terminal adopts the gravity castin...
