Embodiment 1

[0013] First, select a battery with a complete appearance, remove the battery’s constant voltage charging protection circuit board, and conduct a voltage test. The voltage is 3.4V. Charge the battery with a 4.2V universal charger until it is saturated at 4.2V.

Embodiment 2

[0015] First select a battery with a complete appearance, remove the battery’s constant voltage charging protection circuit board, and conduct a voltage test. The voltage is 0.8V. Charge the battery with a universal charger first, and the voltage returns to 4.2V.

Embodiment 3

[0017] First select a battery with a complete appearance, remove the battery’s stabilized charging protection circuit board, and conduct a voltage test. The voltage is 0.5 V. Charge the battery with a universal charger for 5-6 hours, and the voltage is less than 4.2 V. To strengthen the activation, use a 5-6V 300mA DC charger to charge for 5 minutes, test the voltage rise, and then use a universal charger to charge to saturation.

Abstract

The invention relates to a method for activating a lithium battery. The method comprises the following steps of: detaching a voltage-stabilizing charging protection circuit board of the lithium battery; testing the pressure of the battery; and judging whether a universal charger or a direct current charger is used for activation charging according to the categories of high voltage and low voltage. By the method for activating the lithium battery, the activated waste lithium battery is used as a light emitting diode (LED) illumination power supply, has an extremely good effect, reflects the characteristics of lithium batteries, and has high glow brightness and service life of more than 5 years.

Description

technical field [0001] The invention relates to a method for reusing waste batteries, in particular to a method for reusing lithium batteries, which belongs to the field of environmental protection. Background technique [0002] Nowadays, due to the rapid development of communication electronic technology, mobile phones have become an essential communication tool for family members to communicate with each other. Due to the acceleration of communication technology and equipment replacement, every family has mobile phone lithium batteries that are idle due to updates or mobile phone damage. Comes with matching charger. There are more and more obsolete batteries and waste batteries of mobile phones. If we do not recycle them in time and effectively, it will cause serious pollution to our living environment. If we can recycle waste mobile phone batteries in a professional, reasonable and effective manner, the utilization rate of energy will be greatly improved, and at the sam...
