Abstract

The present application discloses a rechargeable lithium battery without a charging port and a manufacturing method thereof. The lithium battery includes a first negative electrode metal casing, a voltage regulation circuit board, a low-voltage positive electrode cap, a high-voltage positive electrode connector, a lithium battery cell, a low-voltage positive/negative electrode insulating spacer, and an insulating housing, wherein an upper end of the first negative electrode metal casing is inwardly provided with a first flange; an upper surface of the voltage regulation circuit board is provided with a negative electrode copper ring and a positive electrode copper ring; the voltage regulation circuit board is welded to an inner side of the first flange of the first negative electrode metal casing through the negative electrode copper ring; and the high-voltage positive electrode connector is arranged on an inner surface of the voltage regulation circuit board. The lithium battery of the present application can stably output a low voltage; the voltage regulation circuit board is welded to the inner side of the first flange, the electrical connection performance is very reliable, and sealing is achieved through solder; no insulating bracket needs to be arranged below the voltage regulation circuit board for support, eliminating the insulating bracket, compressing the height space occupied by the voltage regulation circuit board, and increasing the capacity of the lithium battery cell by increasing the length of the lithium battery cell.
