tuBall™ Batt

• Provides an extensive conductive 3D network between particles, reinforces the electrode and improves its mechanical stability during cycling

• Improves adhesion by establishing strong ties between the particles and allows the amount of binder to be reduced because of an overall reduction in surface area of electrode components and better cohesion

tuBall Batt H2orecoMMenDeD for uSe in grapHite anoDeS anD Si anoDeS of li–ion BatterieS

Key featureS• Ultra-low loadings – less thaN 0.1% of TUBALL™ SWCNT is required in anode formulation

• Faster charge rates • Increased energy density through higher % of active material• Significantly improved cycle life with Si anode• Superior performance at a cost-competitive price

Other benefits such as improved adhesion of active material might be observed depending on the final application of TUBALL™ BATT.

anoDeS WitH tuBall™

• Si and Si—graphite composites are next-generation materials for Li-ion anodes• Si particles expand and contract during charge and discharge• The stress caused by particle volume change leads to rapid failure• TUBALL™ mechanically reinforces the anode and ensures good contact between

the particles• Cycle life improvement is the main benefit of using TUBALL™ in Si anodes

Mixing recoMMenDationS:

Take TUBALL™ BATT• Add water calculated based on target % solids in the slurry; mix for 10 min• Add CMC; mix until CMC is dissolved• Add other conductive additives such as carbon black• Mix until the slurry is homogeneous• Gradually add active material while mixing• Mix until the slurry is homogenous• Add SBR; finish the mixing

The recommendations above are for a water-based anode with CMC and SBR binders. Please contact OCSiAl for other binder systems.

Back in 2009, OCSiAl set out to answer the question: “Is it possible to create an industrial technology for the synthesis of single wall carbon nanotubes, scalable to hundreds of thousands of tonnes per year, and reduce cost by up to one hundred times?”

OCSiAl’s founders view single wall carbon nanotubes as central to improving the properties of most produced materials, a belief that provided them with a unique opportunity to create a company that truly makes the world a better place in which to live.

OCSiAl launched the first industrial production facility for single wall carbon nanotubes on 14 November 2013. With an annual capacity of 10 tonnes it became the largest facility for single wall carbon nanotube synthesis in the world.

On 12 May 2014 OCSiAl launched its core product, TUBALL™. At launch, TUBALL™ was 50 times cheaper than other single wall carbon nanotubes of a comparable quality: $3,000/kg compared to $150,000/kg.

In 2015 OCSiAl opened its own scientific and prototyping centre to facilitate the application of TUBALL™ single wall carbon nanotubes in different materials and applications.

The launch of a new production facility with an annual production capacity of 50 tonnes is planned for 2017.

With experts in physics, chemistry, materials and other scientific fields at the core of the company’s R&D and product development, OCSiAl is easily one of the world’s most experienced teams in the nanomaterials industry.

Headquartered in Luxembourg, OCSiAl is an international technology company with operations in the USA, Korea, Hong Kong, India, Israel and Russia.
