Pure Lithium Corporation is progressing towards Japanese approval for a foundational patent on its lithium metal battery technology.
Pure Lithium Corporation has announced that Japan has issued a notice of allowance, granting the company its foundational patent titled “Vertically Integrated Pure Lithium Metal Production and Lithium Battery Production”, which has previously been granted in the United States and the Kingdom of Saudi Arabia.
This broad patent covers co-locating the production of pure lithium metal anodes and batteries. Pure Lithium’s vertically integrated anode technology yields a high-purity lithium anode, enhancing battery performance.
The company says that by vertically integrating lithium metal anode and battery production, it secures margins at every manufacturing stage. This eliminates costly transportation handling third-party markups and material degradation, significantly reducing overall battery production costs.
“I am honoured that the Japanese patent office has recognised the importance and novelty of our technology,” said Pure Lithium Founder, Chairman, CEO and sole inventor on the patent, Emilie Bodoin.
“Japan pioneered the commercialisation 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.”
Lithium metal anodes replace the graphite anode used in lithium-ion batteries. Graphite, comprising over 97% of lithium-ion batteries and sourced almost entirely from China, occupies half their volume and weight. Pure Lithium says that lithium metal offers ten times the specific capacity of graphite, resulting in a battery that is half the weight and twice the capacity of current lithium-ion batteries.
Because Pure Lithium’s battery technology doesn’t contain graphite, cobalt, nickel or manganese, it can be built from locally sourced materials, cutting out the dependence on materials imported from China. This enables Pure Lithium to produce batteries in global hubs without exposure to volatile tariffs, export bans and other factors complicating today’s battery supply chain.
Pure Lithium currently has over 140 patents and patent applications. The company is progressing towards producing the world’s first commercially viable lithium metal battery, with potential applications spanning grid-scale energy storage data centres micro-mobility drones personal electronic devices and aerospace.
