Problem
Conventional lithium‑ion batteries rely on graphite anodes that limit energy density, charge speed, and power output, constraining the performance and form‑factor of devices ranging from consumer electronics to electric vehicles and aerospace platforms.
Solution
Sila’s Titan Silicon™ anode replaces graphite with a low‑swell silicon‑carbon composite that delivers roughly 20 % higher energy density, enables sub‑10‑minute fast charging, and can provide up to twice the power capacity while maintaining cycle life and safety. The material is engineered as a drop‑in solution compatible with any cell format (pouch, cylindrical, prismatic) and any cell manufacturer, allowing OEMs to integrate it without redesigning their supply chain. Sila also offers Battery Engineering Services, partnering with OEMs and cell suppliers to tailor cell recipes, perform rapid prototyping, and validate performance, accelerating time‑to‑market for high‑energy products. All material is produced at Sila’s U.S. facilities to automotive‑grade quality standards, ensuring consistent supply and traceability.
