In this study, we used tris(trimethylsilyl)borate (TMSB) as an electrolyte additive and analysed its effect on the electrochemical performance of lithia-based (Lithia/Li2RuO3) cathodes. Our investigation revealed that the addition of TMSB modified the interfacial reactions between a lithia-based cathode and

Recently, high-energy density cells containing nickel-rich cathodes and silicon-based anodes have become a practical solution for increasing the driving range of electric vehicles. However, their long-term durability and storage performance is comparatively poor because of the unstable cathode-electrolyte-interphase (CEI) of

Questions

  1. Hello, I have a quick but necessary question. Is the compound stored under inert gas, once it is moisture sensitive? As You do not specify the storing conditions as usual. Thank You for Your quick answer!

    1 answer
    1. This product is packaged under nitrogen. The material may be stored at ambient temperature. The head space should be cleared with nitrogen prior to closure.
