GDI
About Graphenix Development Inc. (GDI)
GDI is a global leader in the research and manufacturing of advanced 100% silicon anode technology for next‑generation Li‑ion batteries. As the demand for electrification accelerates, next‑generation battery materials support electric mobility, defense and aerospace applications, consumer electronics, and renewable energy integration.
GDI has developed and patented a 100% silicon anode that offers higher energy density and significantly faster charging. While silicon is widely recognized as the key to unlocking the future of Li‑ion batteries, technical challenges must be overcome before it becomes the dominant anode material in large‑scale production. GDI is seeking driven, curious, and passionate individuals who want to tackle these challenges and push the boundaries of materials science and manufacturing.
GDI’s focus on true industrial scalability – partnering with global manufacturers and using industrial solar and glass manufacturing equipment already deployed worldwide – enables rapid scale‑up, global manufacturability, and cost‑effective deployment. This positions GDI at the forefront of next‑generation battery materials.
As a key member of GDI’s growing team, you will play a critical role in advancing the company’s mission and contributing to the global fight against climate change. Your work will directly help deliver safer, higher‑performance, and more sustainable batteries for the world.
