  • Charging circuit and module using the same
    Patent number: 10461571
    Abstract: A module includes a charging circuit and a driven unit. The charging circuit includes a power generation element and an electric storage element. The power generation element is connected to the electric storage element to charge the electric storage element. The electric storage element is connected to the driven unit to drive the driven unit with electric power stored. The power-generating voltage of the power generation element has a value equal to or more than the charging voltage of the electric storage element. The electric storage element is a secondary battery including a lithium-transition metal oxide in a positive electrode active material layer, and a lithium-titanium oxide of spinel-type crystal structure in a negative electrode active material layer.
