Iontra Inc is a Denver-based technology company that specializes in advanced battery charging solutions. Founded in 2013, the company has developed proprietary Charge-Control technology that significantly improves battery performance across multiple applications. Their innovations focus on extending battery life, accelerating charging speeds, enhancing safety, and optimizing cold weather performance for various battery types.
Battery Technology
Iontra’s core innovation lies in its patented Charge-Control technology, which uses sophisticated signal processing and adaptive algorithms to optimize battery charging processes. This technology achieves remarkable improvements in battery performance without requiring modifications to existing battery cells or packs.
The system’s intelligent charging methodology prevents common battery degradation issues such as electrode plating and dendrite growth. This results in substantial benefits: battery lifespan increases by 2-4 times, charging times reduce by up to 75%, and batteries can safely charge at temperatures as low as -20°C.
What sets Iontra’s technology apart is its chemistry-agnostic nature, making it compatible with various battery types, including current lithium-ion batteries and emerging technologies like lithium-metal. The technology is implemented through microcontrollers (MCUs) that integrate seamlessly into existing battery management systems.
Recent Projects
In 2024, Iontra secured a $45 million Series C funding round to advance their RISC-V charge control and fuel gauge microcontroller technology. They plan to launch this technology with initial samples available by mid-2025 and full production starting in 2026.
The company also received a $2.15 million ARPA-E Circular Grant from the Department of Energy for developing enhanced EV battery innovations. This project involves collaboration with Idaho National Laboratory and Freudenberg to improve state-of-charge measurements for electric vehicle batteries.
Investors
Iontra has raised a total of $120.3 million through various funding rounds. Their prominent investors include:
- Volta Energy Technologies (lead investor in Series B and C rounds)
- Riverstone
- Flag Asset Management
JPMorgan Chase served as the placement agent for their Series B financing.
