Patent number: 12617017Abstract: The present disclosure relates to a method for creating a powder for use in a selective laser sintering additive manufacturing (AM) application to form a battery component. In one aspect the method may comprise providing a battery component active material, a carbon material and a binder material. The active material and the binder material are mixed together in a first ratio in a mixer for a first time period, to carry out a first mixing operation, to produce a first mixture of active material and binder material. Carbon material may then be added to the first mixture of active material and binder material in a second ratio. The carbon material and the first mixture of active material and binder material may then be mixed for a second time period in a second mixing operation to form a homogeneously mixed powder.Type: GrantFiled: May 26, 2023Date of Patent: May 5, 2026Assignee: Lawrence Livermore National Security, LLCInventors: Jianchao Ye, Yiran Xiao, Zhen Qi, Erika Paola Ramos Guzman
