Shenyang East Chemical Science-Tech (East Chem) and Shanghai Haiyi Scientific Trading (Haiyi) both plan to increase output of the nanotube dispersion in the next two years. According to the manufacturers, the combined capacity of their facilities will reach 40,000 tonnes in 2023–2024.
It is possible to reach 300 Wh/kg energy density and even go beyond this with the said CNTs dispersions.
Nanotubes create long, flexible, conductive, strong bridges to keep silicon anode particles well connected to each other even during severe volume expansion and cracking, which previously limited market use of silicon anodes. This leads to long-lasting, fast-charging batteries for electric vehicles.
