Title:
SOLID-STATE POLYMER LITHIUM BATTERY PACK AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/193227
Kind Code:
A1
Abstract:
A solid-state polymer lithium battery pack and a preparation method therefor. The lithium battery pack comprises single batteries (1), connection sleeve members (2), cables (3), a battery box (4) and a pouring sealant, and has the functions of power supply, power storage and multiple charging/discharging. The preparation method comprises: connecting a plurality of single batteries (1) in series by means of connection sleeve members (2) to form combined batteries; connecting a plurality of combined batteries in series to form a lithium battery pack; and finally, assembling the lithium battery pack into a battery box (4), filling a pouring sealant inside the battery box by means of a sealant pouring process for fixing the single batteries (1) and internal cables (3), and discharging air in the battery box (4), so that a final solid-state polymer lithium battery pack is obtained. The solid-state polymer lithium battery pack has the advantages of high insulation performance, wide working temperature range, long service life, high reliability, excellent mechanical performance such as impact/vibration/noise resistance, and high adaptability to a vacuum environment, is suitable for use in a spacecraft, and can also be used as various devices with requirements on DC voltage output. Moreover, the solid-state polymer lithium battery pack also has the advantages of small size, etc., and can be conveniently embedded into a structure to form a multi-functional structure.
