Technology

Our exceptional silicon-graphene anode material is a game changer for the performance of lithium-ion batteries – in EVs and other electronics.

Applications

Our unique patented silicon-graphene anode material makes it possible to use significantly less anode material for the corresponding storage capacity, compared to traditional batteries. With this exceptional technology, Granode Materials enables smaller and lighter batteries. Another amazing benefit of our anode materials is longevity: it makes batteries last longer and charge faster – qualities that are essential for the next generation of electric vehicles and consumer electronics.

Disruptive nano materials technology

Granode Materials is developing and commercializing an anode material for lithium- ion batteries. By changing the charge carrier to a mix of graphene, nano silicon and binders, our anode material can increase storage capacity dramatically. This is especially true when compared to graphite, the most commonly used material in lithium-ion battery anodes. Our innovative anode material also adds to the mechanical strength and electrical conductivity of the battery. This circumvents the well-known expansion problems and lowering the conductivity of silicon.

The problem

Today’s batteries are facing four main challenges today:

  • Low charge-to-weight ratio

    Current charge-to-weight ratio is too low to support good driving economy in electric vehicles.

  • Slow charging

    Current anodes struggle with long charging times, while the market demand is moving towards instant charging.

  • Low numbers of charging cycles

    Current anodes can only handle a lower number of charging cycles, causing a high lifetime cost.

  • Hard to recycle

    Current anodes are not easily recyclable or they contain rare earth metals that cause secondary environmental challenges.

The solution

Our extraordinary silicon-graphene anode material is designed for next generation batteries and will solve current anode problems:

  • High charge-to-weight ratio

    Granode Materials’ anodes have up to 10 times higher charge-to-weight capacity than current battery anodes!

  • High number of charging cycles

    Granode Materials’ anodes can last up to 10 times longer than current battery anodes!

  • Fast charging

    Granode Materials’ anodes can charge 5-10 times faster than current battery anodes!

  • Easy to recycle

    Granode Materials’ anodes are easier to recycle than current battery anodes!

Cost efficiency – a key factor

Granode Materials’ groundbreaking method is cost-efficient and compatible with commercial fabrication methods. Our manufacturing, which stems from the paper manufacturing industry, is both energy-efficient and inexpensive.

Granode Materials has a local provider of graphene in 2D fab, the company from which Granode Materials spun out of. 2D fab provides sustainable and cost-efficient graphene products and has years of experience and research behind their manufacturing process. Granode Materials also has several ways to manufacture the silicon nano particles needed. The result: reduced costs.
