Abstract

The invention provides an internal series type battery cell and an internal series type battery, which relate to the technical field of batteries. The internal series type battery cell comprises an outer-layer negative electrode piece, an outer-layer positive electrode piece and a battery cell series group, wherein two ends of the battery cell series group are respectively provided with a positiveelectrode end and a negative electrode end; the outer-layer negative electrode piece is connected with the negative electrode end; the outer-layer positive electrode piece is connected with the positive electrode end; the battery cell series group comprises a plurality of internal battery cell electrode pieces which are arranged in an overlapping manner; an internal diaphragm for blocking electrons from passing through is arranged between every two adjacent internal battery cell electrode pieces; every two adjacent internal battery cell electrode pieces mutually form a power supply unit; andthe plurality of power supply units are connected together in series. High output voltage can be obtained; meanwhile, the structure is simple; the running path of electrons in the battery cell seriesgroup is short; the overall internal resistance of the battery cell is reduced; no internal lead occupies space; the energy density of the battery cell can be improved; no internal lead collects current and emits heat; contact is uniform; and the reliability and the consistency of the battery cell are high.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to an internal series battery cell and an internal series battery. Background technique [0002] The current lithium battery cell structure consists of a positive electrode sheet, a negative electrode sheet and a diaphragm. The positive electrode sheet and the negative electrode sheet are separated by the diaphragm to form a cell structure, and the cell voltage platform is 3-4V. [0003] The output voltage of the existing single cell is low, and it is necessary to connect multiple cells in series to increase the output voltage when making daily use (electric vehicles, boats, tools, etc.). At this time, Pack technology is required to realize, and the structure is complicated. [0004] In view of this, it is particularly important to design and manufacture an internal serial battery cell that can directly increase the output voltage of the cell, reduce the overall internal resistan...
