US Patent 10998552 Lithium ion battery and battery materials

In some embodiments, a lithium ion battery includes a first substrate, a cathode, a second substrate, an anode, and an electrolyte. The cathode is arranged on the first substrate and can contain a cathode mixture including LixSy, wherein x is from 0 to 2 and y is from 1 to 8, and a first particulate carbon. The anode is arranged on the second substrate and can contain an anode mixture containing silicon particles, and a second particulate carbon. The electrolyte can contain a solvent and a lithium salt and is arranged between the cathode and the anode. In some embodiments, the first particulate carbon or the second particulate carbon contains carbon aggregates comprising a plurality of carbon nanoparticles, each carbon nanoparticle comprising graphene. In some embodiments, the particulate carbon contains carbon meta particles with mesoporous structures.
