Patent number: 10361427Abstract: An all-solid-state battery having an olivine-type positive electrode active material and a sulfur solid electrolyte and a method for producing the all-solid-state battery is provided. The positive electrode active material is a positive electrode active material in which primary particles aggregate into secondary particles. The primary particles have an olivine-type positive electrode active material and a coating layer that coats all or a portion of the olivine-type positive electrode active material. The coating layer contains a transition metal derived from the olivine-type positive electrode active material, lithium, phosphorous and oxygen as components thereof, and the concentration of the transition metal is lower the concentration of the olivine-type positive electrode active material.Type: GrantFiled: September 16, 2016Date of Patent: July 23, 2019Assignee: Toyota Jidosha Kabushiki KaishaInventors: Mayuko Osaki, Yohei Shindo, Manabu Imano, Hideyuki Koga, Hidenori Miki

Patent number: 10141762Abstract: The all-solid-state battery system that has an all-solid-state battery, the all-solid-state battery having a positive electrode active material layer, a solid electrolyte layer and a negative electrode active material layer, and a control device that controls the lower limit discharge potential of the positive electrode active material layer of the all-solid-state battery. The positive electrode active material layer and/or the solid electrolyte layer have a sulfide solid electrolyte. In addition, the positive electrode active material layer has an olivine-type positive electrode active material. In addition, the capacity of the negative electrode active material layer is lower than the capacity of the positive electrode active material layer. In addition, the control device controls the lower limit discharge potential of the positive electrode active material layer during normal use of the all-solid-state battery to within the range of 1.6 V vs. Li/Li+ to 2.1 V vs. Li/Li+.Type: GrantFiled: November 29, 2016Date of Patent: November 27, 2018Assignee: Toyota Jidosha Kabushiki KaishaInventors: Yohei Shindo, Manabu Imano, Mayuko Osaki, Taishi Shiotsuki
