Problems solved by technology

Once these reserve medicines expire and are not properly recycled and utilized in a timely manner, it is very easy to cause serious consequences such as accidental ingestion, poisoning and environmental pollution.
According to the survey, most of the expired medicines are just discarded as domestic garbage, resulting in a large amount of pharmaceutical waste produced every year
Some drugs have a stable structure and are difficult to degrade. After being washed by rainwater, they enter the groundwater and pollute the water body or soil; some special drugs may cause more serious problems. produce and cause infectious disease

Embodiment 1

[0026] The application of the expired medicine aspirin in this embodiment in the sodium ion battery is carried out according to the following steps:

[0027] (1) Grind expired drug aspirin into powder, and use scanning electron microscope to observe its microscopic appearance, as shown in figure 1 shown by figure 1 It can be seen that the microscopic morphology of aspirin, an expired drug, is mainly rod-shaped, accompanied by particles, and the powder, conductive graphite, and polyvinyl alcohol (PVA) are uniformly mixed at a mass ratio of 7:2:1 to form an electrode slurry;

[0028] (2) Apply the electrode slurry obtained in step (1) evenly on the surface of the copper mesh collector, and dry it in vacuum at 60°C for 24 hours to obtain an electrode sheet;

[0029] (3) The electrode sheet prepared in step (2) was used as the working electrode, the sodium foil was used as the counter electrode and the reference electrode, the non-woven fabric was used as the separator, and the e...

Embodiment 2

[0031] The application of the expired drug aspirin in the lithium-ion battery of this embodiment is carried out according to the following steps:

[0032] (1) Grind expired aspirin into powder, and use Fourier transform infrared spectroscopy to test its microstructure, such as figure 2 shown by figure 2 It can be seen that at a wave number of 3080 cm -1 、2872 cm -1 、1754 cm -1 、1691 cm -1 、1605 cm -1 、1458cm -1 、1095cm -1 、1012 cm -1 corresponding to the stretching vibration of the C-OH bond, -CH 3 The stretching vibration of the bond, the stretching vibration of the C=O bond on the lipid group, the stretching vibration of the C=O bond on the carboxyl group, the stretching vibration of the C=C in the benzene ring, -CH 3 The bending vibration of the C-H bond, the bending vibration of the C-H bond, and the stretching vibration of the C-O bond on the lipid group. Obviously, the main component of the expired drug aspirin is still ethyl o-acetylsalicylate, and the powder...

Embodiment 3

[0036] The application of the expired medicine aspirin in this embodiment in the sodium ion battery is carried out according to the following steps:

[0037] (1) Grind the expired drug aspirin into powder, and evenly mix the powder with acetylene black and polyvinylidene fluoride (PVDF) at a ratio of 6:3:1 to form an electrode slurry;

[0038] (2) Apply the electrode slurry obtained in step (1) evenly on the surface of the nickel foil current collector, and dry it in vacuum at 60°C for 24 hours to prepare an electrode sheet;

[0039] (3) The electrode sheet prepared in step (2) was used as the working electrode, the sodium foil was used as the counter electrode and the reference electrode, the non-woven fabric was used as the separator, and the electrode sheet containing 1 mol / L NaClO 4 A mixture of 5% fluorinated ethylene carbonate, ethylene carbonate (EC) and diethyl carbonate (DEC) is the electrolyte, where the volume ratio of EC to DEC is 1:1, and then filled with high-pur...

Abstract

The invention discloses an application of expired drug aspirin in a rechargeable battery. Expired aspirin tablets are grinded into powder, and uniformly mixed with a conductive agent and a binder based on a proportion to form electrode paste; a current collector is coated with the electrode paste to prepare an electrode plate; next, the electrode plate is assembled into a button type simulation rechargeable battery in a glove box which is full of high-purity argon; the electrochemical performance of the rechargeable battery is tested, and the result proves that the negative electrode material shows high cycling stability; and the application is easy to operate, high in practicability, environment friendly, low in cost, and capable of giving full play to the values of expired drugs, avoiding waste of resources, reliving damage of expired drugs to the environment, facilitating establishment of a cyclic economic industry mode, and protecting the ecological environment.

Description

technical field [0001] The invention relates to the application of expired drug aspirin in a rechargeable battery. Specifically, the expired aspirin is recovered and used as a lithium / sodium ion battery negative electrode active material, which belongs to the field of new energy materials. Background technique [0002] With the improvement of people's living standards and the popularization of health awareness, the types and quantities of medicines stored by families are increasing continuously for emergencies, so that almost every family has more or less stored expired medicines. Once these reserve drugs expire and are not properly recycled and utilized in a timely manner, it is very easy to cause serious consequences such as ingestion poisoning and environmental pollution. According to the survey, most expired medicines are only discarded as domestic garbage, resulting in a large amount of pharmaceutical waste produced every year. Some drugs have a stable structure and ar...
