Embodiment 1

[0128] Using a planetary ball mill for Li 0.35 La 0.55 TiO 3 (High Purity Chemicals) pulverized to prepare particles with a volume fraction median diameter of 200 nm.

[0129] Next, add Li to 10ml of n-hexadecane 0.35 La 0.55 TiO 3 1 g of particles and 0.05 g of octadecyl monoethoxysilane (Azmax Co., Ltd.) were heated at 180° C. for 2 hours on a hot plate while stirring at 300 rpm using a magnetic stirrer.

[0130] Next, using a centrifuge cooled to 10° C., centrifugation was performed at 15,000 rpm for 10 minutes to settle the particles. After removing the supernatant, the particles were again dispersed in 10 ml of n-hexadecane, and centrifuged again under the same conditions. The supernatant was removed, and the obtained precipitate was dispersed in 10 ml of n-hexadecane to obtain a dispersion of surface-treated particles.

[0131] Next, 0.28 g of tetraethoxysilane (High Purity Chemical) was mixed with 10 ml of the obtained dispersion liquid. In addition, the LiNO 3...

Embodiment 2

[0135] As the particles, Li was synthesized with reference to the non-patent literature (Electrochemical and Solid-State Letters, 15(3)A37-A39(2012)).7 La 3 Zr 2 o 12 Except for the fine particles, a molded body of a solid electrolyte was obtained in the same manner as in Example 1.

Embodiment 3

[0147] Use 0.28g of octadecyltriethoxysilane, and add 4ml of silicone (KF-96-10cs, Shin-Etsu Silicone) and 3ml of indane instead of 0.28g of tetraethoxysilane (High Purity Chemical), and Except for this, a molded body of a solid electrolyte was obtained in the same manner as in Example 1.

[0148] The ionic conductivity of the obtained molded body of the solid electrolyte was measured in the same manner as in Example 1. As a result, the total ionic conductivity was 2.1×10 -4 S / cm.

Abstract

A solid electrolyte includes a plurality of particles having lithium ionic conductivity and a matrix which is interposed among the particles so as to be in contact with each of the particles and is formed from an amorphous material containing the following (a) and (b): (a) lithium atoms; and (b) an oxide of at least one element selected from the group consisting of boron, a Group 14 element in period 3 or lower, and a Group 15 element in period 3 or lower.

Description

technical field [0001] The invention relates to a solid electrolyte, a manufacturing method of the solid electrolyte and a lithium ion battery. Background technique [0002] Lithium batteries (including primary batteries and secondary batteries) are being used as power sources for many electrical equipment represented by portable information equipment. Among them, an all-solid-state lithium battery using a solid electrolyte for conducting lithium between positive and negative electrodes has been proposed as a lithium battery that achieves both high energy density and safety (see, for example, Patent Document 1). [0003] Solid electrolytes can conduct lithium ions without using an organic electrolyte, and there is no leakage of the electrolyte, evaporation of the electrolyte due to drive heat, etc., so it is attracting attention as a high-safety material. [0004] As a solid electrolyte used in such an all-solid lithium battery, an oxide-based solid electrolyte having high ...
