Title:
ALL-SOLID BATTERY
Document Type and Number:
Japanese Patent JP2014238925
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an all-solid battery which makes it possible: to increase the ion conduction by increasing the accessibility at an interface of an electrode and a solid electrolytic layer; to suppress the resistive layer formation at the interface; to increase the ion conduction in the electrode; and further to raise the energy density.SOLUTION: A first all-solid battery 10A comprises a lamination including at least, a positive electrode layer 12, an inorganic solid electrolytic layer 14, and a negative electrode layer 16. The first all-solid battery further includes a polymer solid electrolytic layer 18 interposed between the positive electrode layer 12 and the inorganic solid electrolytic layer 14. Further, the positive electrode layer 12 is composed of only a positive electrode active material whose particular crystal plane is oriented in a direction of lithium ion conduction.
