SILKGRAPH

The SilkGraph technology represents an innovative hybrid solution that combines silk proteins with graphene to create advanced materials aimed at high-energy density batteries, composite materials, and energy storage applications. By integrating silicon nanoparticles encapsulated in a 3D matrix made of silk and graphene, the technology overcomes several inherent problems with silicon anodes, such as extreme volumetric expansion, unstable SEI (Solid Electrolyte Interphase) formation, and degradation during charge cycles.

SILKGRAPH: TECHNOLOGY SHOWCASE

CONTEXT AND SILKGRAPH POTENTIAL

Silicon has long been recognized for its high theoretical capacity (4200 mAh/g), surpassing traditional graphite anodes (~372 mAh/g). However, issues like volumetric expansion of up to 300-400% during lithium-ion intercalation, and SEI layer degradation have limited its practical use in battery technology.

SilkGraph solves these problems by encapsulating silicon particles within a flexible, conductive network formed from silk proteins and graphene. This design not only improves battery energy density but also ensures thermal and mechanical stability and long cycle life, making it ideal for applications in electric vehicles, portable devices, and stationary energy storage systems.

INNOVATION IN ANODE DESIGN

The SilkGraph-Si system uses a hybrid design that allows:

Absorbing the volumetric expansion of silicon during charge and discharge cycles, preventing fractures and loss of electrical contact.
Enhancing electronic and ionic conductivity, thanks to the graphene network, which provides continuous pathways for electrons and improves charge/discharge efficiency.
Maintaining a stable SEI layer, reducing capacity loss during the initial charge cycles.

This design stands apart from conventional silicon anodes due to its flexibility, allowing for greater durability and more efficient performance over thousands of cycles.
