Problems solved by technology

At the same time, because these waste lithium-ion batteries contain an electrolyte (lithium salt LipF) that is harmful to the human body, if it is leaked artificially, it will decompose in the air and produce hydrofluoric acid (HF), which has a strong corrosive effect on human bones. Therefore, it will cause serious environmental pollution
In the prior art, the recycling of waste rechargeable batteries only stays in the laboratory, that is, the recovery of the valuable metals contained therein

Embodiment 1

[0016] Embodiment 1: This embodiment consists of a shell, a battery cell, a protection circuit, a spare lighting lamp, a light switch, a charging socket and a power output socket, and the battery cell, a protection circuit, a spare lighting lamp, a light switch, a charging socket and a power output socket They are all installed in the shell, and the charging socket and power output socket, as well as the spare lighting lamp and the light switch are all exposed on one side of the shell. But the cost is higher and the price is more expensive).

Embodiment 2

[0017] Embodiment two: the method for the refurbishment of waste lithium-ion battery of the present invention, its technological process is:

[0018] A. Dismantling: Carefully disassemble the shell of the waste lithium-ion battery to be processed piece by piece, take out the battery cell and protection circuit, clean it, and proceed to the next step;

[0019] B. Detection voltage: measure whether there is voltage in the battery cell. If there is voltage, no matter the voltage is high or low, go to the next step; if there is no voltage, at this time, you can check whether the protection circuit is normal. Check whether chip resistors, capacitors, integrated blocks, and double-sided printed circuit boards are soldered, desoldered, damaged or damaged, repair or replace them as appropriate, then try charging for 10 seconds, and then measure whether the voltage is restored. If the voltage has been restored , no matter the voltage is high or low, enter the next step; if the voltage ...

Abstract

The invention is related to chargeable power supply composed of case, battery core, protective circuit, standby lighting lamp, lamp switch, charging socket, and output socket of power source. Following steps are adopted in fabricating procedure: disassembling, testing voltage, testing capacity, activating function of charge and discharge, testing protective circuit, and sorting and packing. Features are: small size, lightweight, large capacity, and portable. Taking full use of effectiveness of recycled junk lithium ion battery, the invention fabricates quite ideal standby electric power.

Description

technical field [0001] The invention relates to a charging power source, in particular to a universal backup power source and a method for refurbishing waste lithium-ion batteries. Background technique [0002] At present, most of the popular general-purpose backup power supplies on the market, especially those for powering electronic products, are lead-acid rechargeable batteries. Due to the large volume and small capacity of lead-acid rechargeable batteries, this type of backup power supply is used as It is extremely inconvenient to carry around or power mobile electronics. In addition, according to relevant statistics, my country is the country with the largest number of mobile phones in the world. As the price of mobile phones continues to decline, the penetration rate continues to rise. In addition, in recent years, mobile phones have been continuously introduced and updated frequently. There are about 200 million mobile phones every year. Batteries are discarded, most ...
