GDI Si-100% Silicon Anodes for Li-ion batteries

GDI’s patented silicon battery materials offer better performance over standard lithium-ion and emerging solid-state batteries. GDI batteries use the power of Silicon to achieve faster charging times, greater energy density and superior safety.

The need

Li-ion batteries need longer running times and require much faster charging than an hour, without sacrificing safety.

The solution

GDI Si has developed batteries with 30% higher energy, just15-minute charging, and a new standard in safety for Li-ion by solving a key flaw – dendrite formation. The result is a silicon-based Li-ion battery that is superior in performance to current state of the art versions. GDI’s IP-protected manufacturing approach leverages the supply chain, equipment set and advanced processes that are already deployed by the solar industry, allowing GDI to upscale rapidly.

The value proposition

  • Delivers full package of anode and cell.
  • Silicon is a less expensive path to high energy.
  • A non-powder silicon anode is safer and easier to handle than Li-metal.
  • Safety by avoiding Lithium plating and dendrites, helping prevent EV fires/recalls.
  • Silicon is the second most abundant element on earth.
  • Highly scalable path to TeraWatt volumes.
