Making a battery work with silicon

Our patented
materials and
processes address
common
drawbacks

1
Streamlined and Scalable

We leverage manufacturing technologies that already exist and have been scaled. We utilize existing battery roll-to-roll processing. Whatever we do is intended to work at scale.

2
Stable

Silicon anodes quickly degrade due to volume changes associated with lithiation. Cycle stability can be achieved by addressing both the internal and external effects of lithiation on silicon metal. Advano’s proprietary silicon and its material chemistries enable steady rate performance, high areal mass loading, and desired cycle stability.

3
Silicon Crystal and Swell Control

We engineer our material to accommodate silicon swelling and we also engineer the crystal to enhance the operational voltage window of silicon, This enables batteries with enhanced cycle performance and superior charge-performance.

4
Safe

Comprehensive cell-system design – taking into account anode, cathode, and electrolyte – lets us safely maximize the performance of SiNP material.

5
Supply-Chain

Most silicon-based approaches use conventional techniques that disrupt existing supply chains. Our approach works with the systems currently adopted by the world's top manufacturers.

6
Surface Functionalization

Our materials leverage a “surface functionalization” platform that enables not only 3D architecting and surface protection, but also compatibility with polymer and solid electrolyte.

Advano is building and optimizing large-pouch-cell batteries to demonstrate integration capabilities.

 

This will deliver on today’s step-change performance needs, while also providing a platform to rapidly demonstrate future technology.
