Batteries
Start
at the
Cathode.
TENIX® is a proprietary cathode additive engineered to extend cycle life, improve stability, and unlock more value from every cell.
Designed to integrate directly into existing cathode manufacturing processes, TENIX® helps batteries maintain performance longer across lithium-ion chemistries and emerging Mn-rich platforms.
Accepting orders for 2026-27 delivery.
The Challenge
Batteries don’t fail all at once.
They degrade — cycle by cycle.
Over time, repeated charging and discharging causes structural breakdown inside the cathode, leading to resistance growth, thermal instability, and capacity fade.
As batteries power more vehicles, infrastructure, and energy systems, extending battery life is one of the industry’s most important challenges.
The Cathode Drives:
The Solution
Stabilizing Battery Performance at the Material Level
TENIX® is a nano-scale additive designed to improve cathode stability and reduce the degradation pathways that limit battery performance over time.
Integrated directly into existing cathode active materials, TENIX® delivers scalable improvements without requiring entirely new battery architectures.
Helps batteries maintain capacity longer during repeated cycling.
Reduces heat generation and supports safer battery operation.
Supports lower resistance and improved charging behavior.
Small additive percentages integrate into current cathode production.
Validated Performance
Manganese-Rich Cathodes
Enabling the Next Generation of Battery Chemistry
The battery industry is shifting toward manganese-rich cathodes to reduce cobalt exposure, lower material costs, and strengthen supply chain resilience.
But Mn-rich chemistries have historically faced durability and stability challenges that limit commercial adoption.
TENIX® is engineered to address those degradation pathways — helping unlock longer cycle life and improved stability in manganese-rich battery systems.
Why Manganese Matters
-
- Lower-cost chemistry pathway
- Reduced critical mineral dependence
- Stable supply opportunities
- Improved sustainability potential
