Embodiment Construction

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention, using device structures and methods respectively.

[0041] Part 1: Device structure

[0042] Such as Figure 1 to 6 As shown, a liquid metal battery of the present invention includes a ceramic tube 1, a metal base 2 and a metal top cover 3 in the shell structure. The metal base 2 and the metal top cover 3 are coaxially arranged with the ceramic tube 1. The two ends of the ceramic tube 1 are welded to the metal base 2 and the metal top cover 3 respectively. The current extraction end of the metal base 2 forms a groove 6, and the current extraction end of the metal top cover forms a protrusion 5, and the groove 6 and the protrusion 5 must match each other. When the two batteries are connected, the positive electrode of either battery can be connected to the other. The nega...

Abstract

The invention discloses a shell structure for a liquid metal battery and a preparation method thereof. The shell structure comprises a ceramic tube, a metal base used as a positive pole and a metal top cover used as a negative pole, wherein two ends of the ceramic tube are respectively connected with the metal base and the metal top cover to form a sealed battery housing structure. The technical problems of sealing f a liquid metal battery housing, insulation between the positive pole and the negative pole, chemical compatibility between the housing and the active material of the housing and physical and chemical stability within battery storage and operating temperature range are solved.

Description

Technical field [0001] The invention belongs to the technical field of liquid metal batteries, and particularly relates to a shell structure and preparation process for liquid metal batteries. Background technique [0002] At present, my country's power grid is facing many challenges such as the increasing proportion of renewable energy access, the increasingly complex structure of the power system, and the continuous increase of grid load peak-to-valley difference. High-quality, self-healing, safe, clean, economical, and interactive are the goals of my country's smart grid. Energy storage technology, especially large-scale energy storage technology, plays an important role in absorbing renewable energy, improving the stability of the power system, and meeting the demand for peak shaving and valley filling of the grid. Therefore, it is an indispensable key link in the construction of a modern smart grid. Electric energy storage technologies mainly include physical energy storage...
