Abstract
This invention relates to materials for the negative electrode in non-aqueous rechargeable alkali-ion batteries in free-standing form. In particular, this invention relates to the use of metal ribbon that is produced by melt spinning directly as a battery electrode. The invention also relates to a method producing a highly dispersed, multiphase composite material in a single step, as well as a way to generate porosity while maintaining the ‘binder-free’ and ‘additive-free’ characterization of the electrode.
Claims12
A method of producing a battery electrode comprising:
- a) spinning a metal ribbon on a melt spinning apparatus;
- to directly produce a ribbon of Sn alloy or composite material of Sn and at least one of Al and Cu between 20 and 45 micrometer thickness as the battery electrode without powder processing.
