Lithium batteries
Materials for the Lithium Battery Industry
Despite significant advances in the field of energy storage using lithium-ion batteries, many challenges still exist for battery systems, including: energy density, cost optimization, improving safety performance, and extending lifespan. To address these challenges, the TUBALL™ BATT product line from manufacturer OCSIAl utilizes graphene nanotube technology as a breakthrough solution to enhance the performance of lithium-ion batteries. This advanced product significantly contributes to improving the parameters of lithium-ion batteries such as energy density, charging speed, lifespan, and cost.
ANODES SOLUTIONS
Leading Li-ion battery manufacturers have demonstrated that the TUBALL™ BATT H2O product can create anodes containing 20% SiO inside, thereby achieving a record battery energy density—up to 300 Wh/kg and 800 Wh/l. Such battery cells can provide a higher operating range of up to +15% compared to the best Li-ion battery cells on the market.
CATHODES SOLUTION
Compared to using multi-walled carbon nanotubes (MWCNT) and Carbon Black, the application of TUBALL™ Single-Walled Graphene Nanotubes (SWCNT) offers the following benefits:
Safety: TUBALL™ BATT NMP lithium batteries have been proven to be twice as safe as other solutions by reducing the internal resistance (DCR) of the battery during use.
Energy storage density: Graphene Nanotubes can store energy 10 to 60 times more than other solutions.
Discharge power: TUBALL™ helps increase the discharge power of the battery by over 50%.
Adhesion: Graphene Nanotubes enhance the bonding capability between molecules in cathodes.
KEY PRODUCTS
TUBALL™ BATT H2O is a dispersion solution of Graphene Nanotubes in water, used for high-energy silicon (Si) anodes. This solution helps create a robust network within the Si anode and addresses the issue of anode degradation, allowing Li-ion battery manufacturers to use more silicon in the battery formulation, thereby achieving higher energy density and fast charging capabilities.
TUBALL™ BATT NMP is a super-fine dispersion solution of Graphene Nanotubes in NMP, designed for high-energy cathodes. The superior electrical conductivity of TUBALL™ helps improve the safety and energy density of the battery.
