Ecellix Inc., established in 2018 in Seattle, Washington, specializes in developing advanced battery technologies, with a particular focus on high-capacity anode materials for lithium-ion batteries. The company’s innovative approach to silicon-based anode technology offers significant improvements in battery performance and energy density. Founded by Jerry and Jason Schwartz, Ecellix has positioned itself as a significant contributor to the evolution of energy storage solutions. The company’s primary offering, eCellTM, represents a major advancement in anode material technology, providing substantial increases in capacity while maintaining cost-effectiveness and reliability.

Battery Technology

The eCellTM technology developed by Ecellix centers on a micro-porous silicon-carbon composite anode material designed to replace traditional graphite in lithium-ion batteries. This innovative material structure can increase anode capacity by 300-500%, resulting in a 30-50% improvement in overall battery energy capacity. The manufacturing process utilizes silicon monoxide as feedstock rather than expensive silane gas, making production more economical and scalable.

The technology maintains high cycle life, retaining over 80% capacity after 1000 charge-discharge cycles. This performance enhancement comes without compromising safety or requiring significant modifications to existing battery production processes. The silicon-carbon composite structure effectively addresses common challenges associated with silicon anodes, such as volume expansion during charging, while maintaining structural integrity and conductivity.

Ecellix’s approach also focuses on environmental sustainability, with their production methods requiring less energy and generating fewer emissions compared to traditional anode material manufacturing processes.

Recent Projects

In November 2023, Ecellix signed a significant Memorandum of Understanding with HPQ Silicon Inc. and NOVACIUM SAS to advance their Gigafactory vision. This collaboration aims to integrate advanced silicon technologies into large-scale manufacturing operations. The company is currently expanding its manufacturing capabilities in Seattle and evaluating locations for commercial-scale production facilities in Washington state.

Investors

Ecellix has secured approximately $10 million in funding through various investment rounds. Notable investors include Plug and Play Detroit, Catalus Capital, Alliance of Angels, E8, and Keiretsu Forum. These investments have supported the company’s research, development, and scaling efforts in battery technology advancement.
