Novel lead-free zinc chloride battery pack

Abstract

Provided is a novel lead-free zinc chloride battery pack. The novel lead-free zinc chloride battery pack includes a battery shell, a soft packaging discharging assembly and a sealing protection coverassembly; the soft packaging discharging assembly includes a plurality of soft packaging batteries which are connected in series, each soft packaging battery includes a soft packaging battery shell, aroll core assembly and a battery connection lug, electrolyte liquid containing cavities are formed inside the soft packaging battery shells, the roll core assemblies are arranged inside the electrolyte liquid containing cavities and are connected with the battery connection lugs, and the electrolyte liquid containing cavities are filled with zinc chloride electrolyte liquid. According to the novel lead-free zinc chloride battery pack, by arranging the battery shell, the soft packaging discharging assembly and the sealing protection cover assembly and filling the electrolyte liquid containingcavities with the zinc chloride electrolyte liquid, the zinc chloride electrolyte liquid replaces leady electrolyte liquid in traditional technologies to serve as an electrolyte, so that the novel lead-free zinc chloride battery pack has good discharging performance and has the advantages of being high in battery specific energy, simple in recovery process and long in service life.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a novel lead-free zinc chloride battery pack. Background technique [0002] 9V batteries are widely used in the civilian consumer electronics market. Products such as CP9V, CR9V, and ER9V based on lithium-manganese and lithium-substrate systems have always dominated the high-end market because of their technical characteristics such as high energy density, high output power, and long service life. status. [0003] In the application of 9V batteries, lead elements are often used to make lead batteries. Although lead batteries have the advantages of stable voltage and low price, the specific energy of lead batteries is low, and the service life is short, and they need to be replaced frequently. maintain. Moreover, the process of recycling and decomposing batteries containing lead elements is relatively complicated, and the lead elements in the electrolyte are difficult to decom...

[0003] In the application of 9V batteries, lead elements are often used to make lead batteries. Although lead batteries have the advantages of stable voltage and low price, the specific energy of lead batteries is low, and the service life is short, and they need to be replaced frequently. maintain

Moreover, the process of recycling and decomposing batteries containing lead elements is relatively complicated, and the lead elements in the electrolyte are difficult to decompose, resulting in greater pollution to the environment and soil
