Are Contact Lens Batteries the Future of Energy Storage?

A UK startup has developed a revolutionary battery technology using the same flexible polymer found in contact lenses. Called the Faraday 2, this battery is non-toxic, fully recyclable, and safer than conventional lithium-ion cells.

What sets it apart?

Ultra-fast charging capabilities

Flexible and lightweight design, ideal for wearables and medical devices

No risk of fire or explosion, unlike traditional lithium-ion batteries

Suitable for grid-scale storage, offering a sustainable alternative for clean energy systems

If scalable, this innovation could dramatically reshape how we store and use energy quietly replacing the dominant battery tech of today.
