Description of the Related Art In recent years, portable electronic devices have been remarkably reduced in size and weight, and accordingly, there has been a great demand for smaller and lighter batteries as power sources. In order to satisfy such demands, various secondary batteries such as lithium secondary batteries have been developed, and at present, mainly lithium ion batteries are put to practical use.

されている。[0003] Lithium secondary batteries have a remarkably higher theoretical energy density than other secondary batteries, and thus are not only high-performance batteries used in portable electronic and electric equipment, but also recently, new types of batteries for electric vehicles. There is strong interest in batteries. Ideally, lithium metal itself is used as the negative electrode material of this battery, but at present it is difficult to ensure safety, and alternatives to this include lithium alloys and carbon materials that use lithium ions as intercalation.

量が小さいという本質的な問題がある。Various studies have been made on the alloying of lithium, including LiAl, but this type of alloy, in which lithium is used in the skeleton of the alloy, is subject to changes in the lithium concentration in the alloy during charge-discharge. The resulting large phase change and volume change have a fatal disadvantage that the shape of the electrode is broken and the current collection efficiency is reduced. On the other hand, carbon anodes have already been put to practical use, but there is an essential problem that the charge / discharge capacity is small.

に魅力的な材料である。[0005] Against this background, attempts have recently been made to use, as a negative electrode material, a silicon oxide in which Li is reversibly inserted and released between lattices. Above all, the SiO negative electrode has about three times the capacity of the carbon (graphite) negative electrode, and is a very attractive material.

Therefore, for example, as shown in FIG. 2, a large amount of an electronic conductive matrix such as flake graphite is mixed.

Increasing the contact area with the silicon oxide particles by reducing the size as shown in (1) is also one means of improving the electronic conductivity, but in this case, the surface area of the graphite particles themselves increases, and the reactivity with the electrolyte decreases. It is dangerous because it causes fire and ignition.

I do. The electron conductive material layer may have at least a part of the surface of the silicon oxide particles. Since silicon oxide has very low electronic conductivity, it is necessary to provide electronic conductivity between the particles. Therefore, instead of using a negative electrode material prepared by mixing a conventional silicon oxide and an electron conductive matrix, a nonaqueous electrolyte is used by using a negative electrode material having an electron conductive material layer on the surface of silicon oxide particles. The next battery is made. The energy density of the battery has improved,

In order to dissolve the lithium salt of the supporting electrolyte, the non-aqueous electrolyte has a high dielectric constant and an appropriate solvation ability with lithium ions.
