Abstract

The invention provides a lithium slurry battery and a lithium slurry battery module. The lithium slurry battery comprises a battery cell unit, wherein the battery cell unit comprises a battery cell, abattery cell bag and a monomer housing cover; a battery cell bag connection part of the monomer housing cover can be matched with the size of a battery cell bag opening, so that the battery cell bagopening can sleeve the battery cell bag connection part and is hermetically connected with the battery cell bag connection part; the single battery cell unit can be further arranged in a monomer housing to form the lithium slurry battery, or a plurality of battery cell units can be further arranged in a plurality of accommodating cavities of a multi-grid module housing to form the lithium slurry battery module. In addition, a connection interface of lithium slurry battery maintenance and regeneration equipment can be further formed in the monomer housing cover and / or a module housing cover. Asthe lithium slurry battery and the lithium slurry battery module are high in sealing property, can be maintained on line and are simple in structure and convenient to remove, automatic assembling andrecycling of batteries are facilitated. Furthermore, the invention further provides preparation methods of the lithium slurry battery and the lithium slurry battery module.

Description

technical field [0001] The invention relates to the field of chemical power batteries, in particular to a lithium slurry battery, a module and a preparation method thereof. Background technique [0002] Lithium-ion battery is a new type of high-energy battery with lithium-intercalated compounds as positive and negative electrode materials. Compared with lead-acid batteries and nickel-metal hydride batteries, it has a series of advantages such as high specific energy, high voltage, small self-discharge, good cycle performance and long life. Advantages, more and more people's attention. At present, lithium-ion battery packaging processes mainly include soft packs, cylindrical hard shell packs, and square hard shell packs. However, none of the existing packs can maintain and regenerate the battery, and thus cannot prolong the service life of the battery. In addition, the square hard-shell battery is connected to the battery case cover and the lower case by welding, and the bat...
