Abstract

A lightweight lithium-ion battery module for an underwater device and a manufacturing method thereof. The overall structure of the module is an open structure with single-sided bonding and suspension support, including a panel, a first insulating plate, a battery stack, a second insulating plate, Guide supports, side supports, bottom supports, top supports, and electrical connectors. The first insulating board and the panel are respectively coated with silicone rubber and the silicone rubber is bonded together and cured for more than one day. The battery stack and the first insulating board are respectively coated with silicon rubber and bonded together and cured for more than five days. The second insulating board Installed to the other side of the battery stack for insulation without support. The guide support, the side support, the bottom support and the top support are not in contact with the battery stack. The invention adopts the one-sided adhesive suspension and flexible interconnection technology of the lithium-ion battery combination, which significantly reduces the specific gravity of the structural parts of the lithium-ion battery module and ensures its reliability at the same time.

Description

technical field [0001] The invention relates to a lithium-ion battery module and a manufacturing method, in particular to a lightweight lithium-ion battery module and a manufacturing method for underwater equipment. Background technique [0002] With the development of science and technology, the application range of lithium-ion batteries is becoming wider and wider. Users have higher and higher specific energy requirements for lithium-ion battery modules, especially battery packs for underwater equipment. However, the large proportion of the weight of the module structural parts is often one of the important reasons for the low specific energy of the lithium-ion battery module. This patent relates to a lightweight lithium-ion battery module for underwater equipment. The lithium-ion battery stack is fixed on an approximately circular and hollowed-out panel by one-sided bonding and hanging to fix the battery stack, which minimizes the lithium-ion The weight of the structura...
