摘要: The disclosure provides a battery and a battery manufacturing method. The battery includes a cell (10), and the cell (10) includes a cell body (11) and a tab (12). The tab (12) extends from the cell body, and the tab (12) includes a first solder mark (121) and a second solder mark (122). The second solder mark (122) covers the first solder mark (121), and the second solder mark (122) is formed with a circumferentially closed space (123) to expose the first solder mark (121). That is, when welding the tab (12) and the cover plate assembly, the tab (12) is welded twice, and a hollow second solder mark (122) is formed.

摘要: The present invention provides a battery pack, comprising a first cell and a second cell connected in series, the first cell having a current cut-off device and having a first failure voltage, the current cut-off device being configured to be able to break a circuit in response to a voltage value of the first cell reaching or exceeding the first failure voltage, and the second cell having no current cut-off device. According to the technical solution of the present invention, the battery pack may use a soft pack battery as the second cell, having advantages such as high energy density, low impedance, high discharge power, a low rate of temperature rise during high-rate discharge, and flexibility in dimensions. At the same time, a cylindrical battery may be used as the first cell; this has a built-in current cut-off device, so can mitigate the problem of soft pack batteries being susceptible to overcharging and consequent thermal runaway, thus improving safety.
