Doubling the capacity of rechargeable batteries



  • Imagine if your phone lasted a week, 

  • If your car could drive 2000 km without a recharge,

  • If the batteries that powered them were made from recycled materials.



Ionobell licenses the technologies necessary to migrate Li-Ion batteries to 70% Si anode designs, achieving 2X initial performance improvement with 8X potential capability improvement in the long term.

We can double battery capacity, reduce the cost and more environmentally friendly

Our designs achieve over 800 wh/L, stable past 1000 cycles, minimal swelling, near 100% coulombic efficiency, and with all carbon and Si materials from waste materials.
