1. A lithium-ion battery module, comprising:
a housing having a base;
a battery cell disposed in the housing in a cell orientation direction, wherein the cell orientation direction is substantially parallel to the base; and
a battery module terminal electrically coupled to a battery cell terminal of the battery cell via an electrical pathway, wherein the battery cell terminal extends from the battery cell in the cell orientation direction, wherein the battery module terminal is configured to provide an electrical output of the battery module when coupled to an electrical load, and wherein the electrical pathway extends from the battery cell terminal to the battery module terminal and is defined by a first portion, a second portion, and an interconnecting portion connecting the first and second portions;
wherein the first portion of the electrical pathway comprises a plurality of first conductive components having a first conductive material, the plurality of first conductive components are electrically coupled to one another within first connection planes using a first weld technique, a first conductive component of the plurality of first conductive components is directly coupled to the battery module terminal, and the first connection planes are substantially parallel to the base of the housing; and
wherein the second portion of the electrical pathway comprises a plurality of second conductive components having a second conductive material, the plurality of second conductive components are electrically coupled to one another within second connection planes using a second weld technique, different from the first weld technique, a second conductive component of the plurality of second conductive components is directly coupled to the battery cell terminal of the battery cell, and the second connection planes are oriented crosswise relative to the first connection planes and the cell orientation direction.
