We are thrilled to announce that Sienza Energy is the latest company to join the Kairos portfolio.

Sienza Energy is a technology company exploring a radical new approach to energy storage in the way they design and manufacture batteries. The company’s revolutionary strategy is based on a 3D nanotechnology electrode structure that takes advantage of advances in multiple fields over the last decade, providing an approach to battery design that is unique in the industry. By combining these advances in an innovative way, Sienza can drastically improve the batteries’ energy and power densities — all with the goal of reducing the overall battery costs. With this new approach, Sienza Energy plans to provide even more capability into a range of applications, from smart devices to electric vehicles.
