Silicon-Carbon Batteries: A New Era Beyond Lithium-Ion

For decades, lithium-ion batteries have powered our smartphones, laptops, and electric vehicles. Their reliability and safety made them the gold standard. But their performance has barely improved in recent years. Most gains have been small, just 3 to 5% per generation.

The core issue lies in the anode material: graphite. It can only store so many lithium ions. Its maximum capacity is capped at 372mAh/g. That limit has held back real progress. As devices get thinner and more powerful, battery life has become a growing pain point.
