  • Patent number: 10919112
    Abstract: A negative electrode for an electrochemical cell of a lithium metal battery may be manufactured by joining together a metallic current collector piece and a lithium metal piece. The metallic current collector piece may be positioned adjacent the lithium metal piece in an at least partially lapped configuration at a weld site. A laser beam may be directed at an upper surface of the metallic current collector piece at the weld site to melt a portion of the lithium metal piece adjacent the metallic current collector piece and produce a lithium metal molten weld pool. The second laser beam may be terminated to solidify the lithium metal molten weld pool into a solid weld joint that physically bonds the lithium metal piece and the metallic current collector piece together at the weld site.
