Summary of the clip:
Can a 'boring' chemical like titanium dioxide outperform advanced battery anodes?
Titan B is an advanced anode material based on titanium dioxide (TiO2), a famously stable and abundant chemical. It boasts a high theoretical capacity of around 330 mAh/g, which is nearly double that of the incumbent high-power anode, Lithium Titanate (LTO), which sits at approximately 170 mAh/g. This fundamental advantage in specific capacity allows for a significant increase in the energy density of the final battery cell.
A key structural advantage of this material is its "zero-strain" property, meaning it experiences negligible volume expansion and contraction during the insertion and extraction of lithium ions. This incredible structural stability is the primary reason for its potential for an exceptionally long cycle life, as it minimizes the mechanical degradation that plagues many other anode materials like silicon. This makes it ideal for applications requiring tens of thousands of cycles.
The material's electrochemical profile provides inherent safety benefits. It operates at a high voltage relative to lithium metal, which physically prevents the formation of lithium dendritesโa primary cause of short circuits and thermal runaway in conventional batteries. While this high voltage enhances safety and enables faster charging, it does limit the overall cell voltage and thus energy density, a trade-off TioTech is addressing through parallel cathode development.
In this short video, you can learn:
* The chemical identity of the Titan B anode material (Titanium Dioxide).
* How its theoretical capacity compares to conventional Lithium Titanate (LTO).
* The benefits and drawbacks of its "zero-strain" structure and high voltage profile.

How do you engineer a common material to retain over 90% capacity at a 5C charge rate?
How do you engineer a common material to retain over 90% capacity at a 5C charge rate?
This clip presents half-cell performance data that highlights Titan B's superior rate capability compared to other forms of titanium dioxide. The material demonstrates remarkable capacity retention, maintaining over 90-95% of its initial capacity at C-rates as high as 5C. This is a significant leap forward, as typical state-of-the-art TiO2 materials can lose up to 70% of their capacity under the same demanding fast-charge conditions.
The speaker provides context by comparing Titan B to other high-performance TiO2 polymorphs, specifically the "bronze" phase. While TiO2 bronzes have been known for decades to have excellent electrochemical traits, they suffer from a critical flaw: they are metastable. This inherent instability makes them extremely difficult and expensive to synthesize consistently at an industrial scale, which has prevented their widespread commercial adoption.
TioTech's core innovation is a materials engineering breakthrough that sidesteps this manufacturing challenge. Instead of trying to produce a difficult metastable material directly, they have developed a proprietary process to achieve the high capacity and fast-charging characteristics of advanced phases while starting with a stable and common anatase TiO2 precursor. This clever engineering approach unlocks high performance without the associated manufacturing penalties.
In this short video, you can learn:
* Titan B's capacity retention at high C-rates (up to 5C).
* The manufacturing challenges associated with metastable TiO2 bronze phases.
* TioTech's engineering strategy to achieve high performance from a stable precursor material.

What happens when you shoot, drill, and short-circuit a battery cell... and it keeps working?
What happens when you shoot, drill, and short-circuit a battery cell... and it keeps working?
A critical advantage of Titan B is its exceptional thermal stability during high-power operation. Unlike conventional graphite anodes that generate significant heat and require complex liquid cooling systems, Titan B cells exhibit a minimal temperature increase of less than 5ยฐC during an extreme 10C charge. This drastically simplifies battery pack design, reduces system weight and complexity, and improves overall reliability in demanding industrial applications.
The clip showcases the results of extreme physical abuse testing, including a ballistics test where a functioning cell was shot with a projectile. Incredibly, the cell did not experience thermal runaway, catch fire, or explode. It not only remained safe but also retained a voltage and could still be charged and discharged for days after the event, demonstrating a level of physical robustness far beyond typical lithium-ion chemistries.
Further safety validation is provided through drilling and short-circuit tests. The cells show no swelling, sparks, or flames when drilled through. Furthermore, they can be fully short-circuited to zero volts and subsequently recharged to regain all of their capacity. This highlights an unprecedented resilience to both mechanical and electrical abuse, making the chemistry extremely safe for complex and high-stakes environments.
In this short video, you can learn:
* The minimal heat generation of Titan B cells during extreme fast charging (10C).
* The results of a live ballistics test on a functioning battery cell.
* How the chemistry responds to being drilled and subjected to a zero-volt short-circuit.
๐ **Clip Abstract** Witness the incredible safety and thermal stability of Titan B battery technology through a series of extreme abuse tests. This clip covers its low heat generation during fast charging and its remarkable resilience to being shot, drilled, and short-circuited.
