Project Description

‍
Tyfast Energy Corp. is developing high-performance lithium batteries engineered for fast charging, extended cycle life, and high-temperature operation. These batteries aim to provide ultra-fast three-minute charge times and an industry-leading 20,000-cycle lifespan, making them ideal for autonomous and high-duty cycle applications that run 24/7.

UC San Diego’s Energy Storage Group is conducting comprehensive testing on Tyfast’s pouch cells, including capacity evaluation, performance testing, and destructive safety analysis, to assess their viability for commercial deployment.

The project will leverage 22 dedicated testing channels at CER’s Energy Storage Innovation LAB (ESIL) to validate performance under real-world conditions.

Testing & Research Goals
Performance Testing (UC San Diego)

• Capacity Testing: Ensuring cells exceed 1,000 mAh discharge capacity at 2.5V–3.9V.
• Rate Testing: Evaluating charging and discharging rates at -40°C, -20°C, 0°C, +20°C, +40°C at 1C, 5C, and 10C rates.
• Cycle Life Testing: Running long-term cycle tests at various temperatures until cells reach 80% capacity retention.

Destructive Safety Testing (Third-Party Facility)

• Impact Testing – Assessing cell durability under physical stress.
• Crush Testing – Simulating compression damage scenarios.
• Short Circuit Testing – Evaluating internal failure risks.
• Nail Penetration Testing – Measuring resistance to puncture-induced thermal runaway.
• Accelerated Rate Calorimeter (ARC) Testing – Analyzing thermal stability and heat generation.

Testing will take place over 9 months, with bi-monthly progress reviews and a final report by December 2025.

Project Results
(Results will be updated as testing progresses.)

Initial Findings:‍

• Charge Rate Validation – Evaluating the feasibility of three-minute ultra-fast charging.
• Temperature Resilience – Measuring performance across extreme hot and cold conditions.
• Cycle Life Assessment – Validating 20,000+ charge cycles without degradation.
• Enhanced Safety & Stability – Identifying improvements over conventional lithium-ion technology.

Next Steps:‍

• Optimization & Scaling – Refining Tyfast’s manufacturing process for mass production.
• Industry Adoption – Exploring use cases in autonomous vehicles, robotics, and energy storage systems.
• Commercial Readiness – Ensuring compliance with UL1642 safety standards for market deployment.

This project will serve as a living research initiative, with ongoing data collection and updates as testing progresses.
