Pure Lithium Corporation announced that Japan’s patent office has issued a notice of allowance for its foundational patent, “Vertically Integrated Pure Lithium Metal Production and Lithium Battery Production.” This approval follows earlier grants in the United States and Saudi Arabia. The patent covers the co-location of lithium metal anode manufacturing and lithium metal battery assembly under one roof, a configuration designed to produce ultra-high-purity lithium metal anodes and optimize overall battery performance.
By integrating anode and battery production, Pure Lithium captures margin at each manufacturing stage and removes the costs associated with transportation, handling, third-party markups and material degradation. According to the company, this streamlined approach can significantly cut battery production expenses while delivering a lithium metal battery with an anode twice the capacity and half the weight of traditional lithium-ion cells that rely on graphite.
“I am honored that the Japanese patent office has recognized the importance and novelty of our technology,” said Pure Lithium Founder, Chairman, CEO and sole inventor on this patent, Emilie Bodoin. “Japan pioneered the commercialization of the lithium-ion battery that is ubiquitous in today’s world, and securing protection for our lithium metal battery intellectual property in the country is a significant milestone. I am confident that Pure Lithium’s technology can play an important role in helping Japan reclaim and expand its battery market share by enabling next-generation lithium metal innovation. We will continue pursuing broad intellectual property protection across Asia.”
Pure Lithium’s batteries eliminate key materials sourced predominantly from China—graphite, cobalt, nickel and manganese—and instead rely on locally sourced feedstocks. This supply-chain design provides the first fully non-China-dependent production route for lithium metal batteries, reducing exposure to tariffs, export controls and other geopolitical risks.
With over 140 patents and pending applications worldwide, Pure Lithium is advancing toward commercializing its lithium metal battery. Target applications include grid-scale energy storage, data centers, micro-mobility, drones, consumer electronics and aerospace systems.
