Carbon additives are being used in a variety of industrial and consumer applications. Carbon's revolutionary technology has a range of uses, including aerospace, automotive, electronic manufacturing, and battery production. In industrial settings, carbon-fiber reinforced material offers superior strength/weight ratios. It also allows for more complex part designs than would otherwise be possible with photopolymer print technology. Carbon's unique technology has also opened up new opportunities for spare-part production, an application that has seen rapid growth in the automotive industry as a result of the recent FIA Formula E series.
Impossible Objects partnered in 2021 with the designer luxury jewellery brand LACE to produce a range of jewelry featuring carbon fibres 3D-printed. It was a milestone collaboration for this revolutionary technology.
Because of their high conductive qualities, porous carbon solutions play a vital role in the manufacture of lithium-ion cells that are used to power a wide range of electronic portable devices and vehicles. Carbon blacks in batteries are crucial for gas diffusion, which controls the flow of water and hydrogen. Imerys’ carbon black solutions allow for faster charging and higher energy densities, whilst also reducing the costs of batteries.
For lithium-ion batteries, the electrode/electrolyte interface (EEI) is an essential component in the cell's performance and life cycle. During LIB charging/discharging, there are chemical reactions that occur between the electrode and the electrolyte interface. These reactions have the potential to impact on cell performance. It is common to use conductive additives in LIB electrodes. But their surface reaction has yet to be fully understood. According to a new study, the reactivity and surface structure of EEI carbon black can be controlled by their electrolyte composition.
A layered structure with a reduced sulfur/nitrogen concentration and less reactive layers allows for improved carbon-electrolyte interaction. They are essential in the formation of the EEI which, once formed, is irreversible (Gauthier et. al.,2015).
There is some uncertainty about the coal-carbon additives' behavior. To help understand the differences in reactivity, a series of studies was conducted to examine the EEI formation of a composite electrode with varying amounts of conductive carbon additive, ranging from no addition to the highest concentration. The best results were achieved using onion-like conductive carbon which had the lowest surface and heteroatom contents. Additionally, onion-like reactivity is less sensitive to changes made in the EEI. The findings of these studies are an important step in understanding the role that carbon additives play on EEI dynamics and could lead to the development of more efficient and stable lithium-ion battery electrodes.
