▎ 摘  要

NOVELTY - The electrochemical cell has: a cathode; an anode (1240); an electrolyte separator (1230) comprising a ceramic material located between the cathode and the anode; and an anode current collector (1250). The anode is located between the anode current collector and the electrolyte separator. The anode comprises a three dimensional porous anode including: ionically conducting electrolyte strands extending through the anode from the anode current collector to the electrolyte separator; pores (1245) extending through the anode from the anode current collector to the electrolyte separator; and an electronically conducting network extending on sidewall surfaces of the pores from the anode current collector to the electrolyte separator. USE - Electrochemical cell is useful in a lithium-ion battery (claimed). ADVANTAGE - The presence of the electronically conducting networks allow lithium plating not only at the current collector, but also at the surface of the pores, thus significantly reducing the local current density and avoiding or reducing lithium dendrite formation and short circuit. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-section of a solid-state battery with a three-dimensional porous anode. 1200Solid-state battery 1210Cathode current collector 1220Cathode structure 1230Electrolyte separator 1232Strands of solid-state electrolyte 1240Anode 1245Pores 1250Anode current collector
