  • Publication number: 20230107067
    Abstract: Resin-adhered graphite particles are obtained by causing a modified novolac-type phenolic resin to adhere to graphite particles. At least part of surfaces of the graphite particles is coated with a carbonaceous coating by heating the resin-adhered graphite particles in a non-oxidizing atmosphere at 900 to 1,500° C. to carbonize the modified novolac-type phenolic resin. Arylene groups having hydroxy groups account for 5 to 95 mol % of arylene groups constituting the modified novolac-type phenolic resin. The obtained carbonaceous substance-coated graphite particles exhibit excellent battery properties when used as a negative electrode material for a lithium ion secondary battery.

  • Publication number: 20230038665
    Abstract: Embodiments in accordance with the present invention encompass compositions comprising a long shelf stabilized organopalladium compound of formula (I) as described herein. The composition further contains a photoacid generator, a photosensitizer and one or more olefinic monomers as described herein. The shelf life of the compositions can further be extended by employing a stabilizer, such as for example, a hindered amine. The composition undergoes vinyl addition polymerization when it is exposed to a suitable actinic radiation to form a substantially transparent film or a three dimensional object. More specifically, the compositions of this invention are stable at room temperature for several days to several months and can also be stored at higher temperatures from about 40° C. to 60° C. for several days and undergo mass polymerization only when subjected to suitable actinic radiation.
