But Why?

4 deep reasons that led to 1 simple question.

Depleting Critical
Resources

Today's batteries rely on scarce materials like lithium and cobalt, mined unsustainably and with limited availability.

High Costs,
Limited Access

The expensive production of traditional batteries keeps renewable energy solutions out of reach for many.

Safety Risks You
Can't Ignore

Leaking chemicals, overheating, and explosions make current batteries a hazardous choice for everyday use.

Recycling That Just 
Isn’t Working

Inefficient and energy-intensive recycling processes mean most batteries end up polluting the planet.

Is this really how we want to power the future of green energy?
