Abstract

The invention discloses a flanged cylindrical battery with a spiral wound electrode, and aims to solve the problem that the working efficiency of a battery pack is relatively low because the battery pack cannot be effectively ventilated and cooled due to the filling of electrolyte when the battery pack is formed by a conventional cylindrical battery, and the flanged cylindrical battery comprises a fixing frame, placing grooves distributed at equal intervals are formed in the outer wall of the top of the fixing frame, mounting wire grooves are formed in the inner walls of the bottoms of the placing grooves, fixing bases are arranged on the inner walls of the bottoms of the placing grooves, grooves are formed in the outer walls of the tops of the fixing bases, and the grooves are arranged to be of a structure with the narrow upper portion and the wide lower portion. The grooves are arranged to be of the structure with the narrow upper portion and the wide lower portion, the electrolyte is loaded in the grooves, the electrolyte cannot be spilled out even if the battery pack shakes to a certain degree, in this way, air holes can be reasonably formed in the outer walls of the two sides of the fixing frame, and the heat dissipation effect of the battery pack in the fixing frame is effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of cylindrical batteries, in particular to a flanged cylindrical battery with spirally wound electrodes. Background technique [0002] At present, the cylindrical battery is a battery with high capacity, long cycle life and wide operating environment temperature. Products are used in solar lamps, lawn lamps, backup energy, power tools, toy models, and photovoltaic energy. It is divided into different systems of lithium iron phosphate, lithium cobaltate, lithium manganate, cobalt-manganese mixture, and ternary materials. The shell is divided into two types: steel shell and polymer. Different material systems have different advantages. Mainly steel-cased cylindrical lithium iron phosphate batteries. Iron-lithium batteries are characterized by high capacity, high output voltage, good charge-discharge cycle performance, stable output voltage, high-current discharge, electrochemical stability, and safety in use ...
