Disclosed herein is a high-voltage battery module including a bridge bus bar configured to be exposed to the outside in order to reduce a danger of accident due to electric shock when handing the high-voltage battery module, wherein a cell assembly is temporarily electrically open-circuited and the bridge bus bar is connected only when the battery module is used. It is possible to remove dangerous factors that may injure the human body during manufacture and transportation of the high-voltage battery module and to use the high-voltage battery module in the state in which restrictions are minimized.

Disclosed is a cleavage flaking type lithium ion battery and a preparation method thereof. The cleavage flaking type lithium ion battery includes a battery shell and a winding electric core; the winding electric core includes a battery pole piece which includes a coating region and a blank region adjacent to the coating region coated with an electrode material, and the blank region is directly connected with the battery shell or with a metal contact on the battery shell.
