Vanisperse LI
For more than 50 years, Borregaard’s Vanisperse® products have played a crucial role in ensuring the optimal performance of lead batteries worldwide. Now, we are introducing Vanisperse LI, the latest addition to the Vanisperse family, designed to enhance and optimise both the production process and performance of lithium-ion (Li-ion) batteries.
Vanisperse LI is a highly effective dispersant for conductive carbon and active material in water-based electrode slurries. Our bio-based additive effectively reduces slurry viscosity, enabling higher solid content and smoother processing in battery cell manufacturing. These enhancements lead to increased production throughput and significant cost savings in terms of energy and time.
Optimised particle dispersion is essential for electrode performance. Vanisperse LI ensures a uniform and homogeneous distribution of active materials while delivering excellent slurry stability. Our dispersant is highly effective at preventing the agglomeration of conductive carbons, such as high-surface-area carbon black and carbon nanotubes (CNTs). Improved particle dispersion, combined with increased mass loading, enhances conductivity and electrode areal capacity. Additionally, it provides the ability to modify the pore structure and adjust the density of the electrode coating.
Vanisperse LI has also been proven to perform effectively with innovative technologies, such as silicon anode formulations. Derived from Norway spruce, Vanisperse LI offers a more sustainable and environmentally friendly alternative to synthetic dispersants, contributing to the reduction of your Scope 3 emissions.
How to improve electrode properties
Incorporating a dispersant into the formulation can enhance coin cell performance by optimising particle dispersion and reducing slurry viscosity. This leads to improved conductivity, increased areal capacity, and the ability to modify the density and pore structure of the electrode coating.
De-agglomeration of carbon nanotubes
Efficient dispersion of conductive carbon is essential for ensuring uniform electrode composition and optimising battery performance. Vanisperse LI is a powerful dispersant for a wide range of carbon materials used in lithium-ion battery electrodes, including high-surface-area carbon black and carbon nanotubes (CNTs)
More on batteries
All you need to know about batteries
To appreciate the invention of the battery, it is wise to give some perspective by first recognising the development of the primary purpose of its invention - that is, the generation and storage of electricity.
Norway spruce – a unique raw material
Borregaard operates the world’s most advanced biorefinery, and our most important raw material is wood, more specifically, norway spruce harvested from certified forests with short transport routes.
All you need to know about safety in li-ion batteries
Lithium-ion (li-ion) batteries are lightweight, efficient, and have a high energy density compared to other batteries. li-ion batteries are widely applied in diverse areas ranging from small appliances such as smartphones, tablets, laptops, and power tools to electric and hybrid vehicles and energy storage systems. common for all these battery systems is that a high safety level is required.
