  • Publication number: 20210175512
    Abstract: A lithium-ion rechargeable battery (1) includes: a positive electrode layer (30) containing a positive electrode active material; a solid electrolyte layer (40) containing an inorganic solid electrolyte; a storage layer (50) made of porous platinum (Pt) and storing lithium; a coating layer (60) made of an amorphous metal or alloy; and a negative electrode collector layer (70) made of platinum (Pt); these layers are stacked in this order.

  • Publication number: 20200381701
    Abstract: A method for manufacturing a lithium-ion rechargeable battery (1), the lithium-ion rechargeable battery including: a positive electrode layer (30) containing a positive electrode active material; a solid electrolyte layer (40) containing an inorganic solid electrolyte; a storage layer (50) made of porous platinum (Pt) and storing lithium; a coating layer (60) made of an amorphous chromium-titanium (CrTi) alloy; and a negative electrode collector layer (70) made of platinum (Pt); these layers are stacked in this order. The storage layer (50) is first composed of a dense platinum layer formed by sputtering, and then undergoes initial charge and discharge to become porous, which results in a porous part (51) and a number of pores (52) being formed. This method of manufacturing the lithium-ion rechargeable battery (1) restrains or prevents peeling inside the all-solid lithium-ion rechargeable battery.

  • Publication number: 20200259171
    Abstract: A lithium-ion rechargeable battery (1) includes: a positive electrode layer (20) containing a positive electrode active material; a solid electrolyte layer (30) containing an inorganic solid electrolyte having lithium ion conductivity; and a negative electrode collector layer (50) serving as a negative electrode. The negative electrode collector layer (50) includes: a storage layer (51) containing multiple columnar crystals made of metal titanium and each extending in a thickness direction; and a coating layer (52) coating the storage layer (51). By a charging operation of the lithium-ion rechargeable battery (1), a negative electrode (40) made of metal lithium is formed at grain boundaries inside the storage layer (51). This prevents peeling inside the all-solid lithium-ion rechargeable battery.
