Scientists have solved the charging problem of magnesium batteries, and are expected to replace lithium batteries as "new favorites".
The use of lithium batteries has been very popular in our lives, and is widely used in electronic products such as mobile phones and computers due to their excellent performance. Even so, manufacturers and scientists are looking for cost-effective batteries to replace lithium batteries. Recently, it has been reported that an energy laboratory in the United States has successfully developed a solid state battery of magnesium metal, which is better than lithium battery for material cost or energy storage, which is the most cost-effective.
In the metal storage of the earth, magnesium itself is more abundant than lithium. In other words, the cost of magnesium batteries is lower and its storage capacity is two times that of lithium batteries, but there are still bottlenecks in the experiment.
The principle of lithium batteries is that there is electrolyte flow between positive and negative poles. This chemical reaction provides the battery with energy that will not recharge the battery if it is irreversible. But in the course of the experiment, the scientists found that its carbonate was a hindrance to the battery charging, so the birth of the magnesium battery was not as simple as it was imagined.
Some scientists have suggested that magnesium batteries can be charged and discharged by corrosion of liquid electrolytes, but this means that magnesium batteries do not work properly under high pressure, and there is a potential safety hazard. So the scientists came up with a magic trick to mix polypropylene cyanide and magnesium ions together as solid electrolytes, which could protect the anode of the magnesium battery and increase the performance of the battery by the way.
Scientists have put this idea into practice and made the prototype of a magnesium solid battery. If the test is used without problems, it can be put into production on a large scale. The metal content of magnesium is higher than that of lithium. It is the eighth one in the metal rankings, two times the power supply or the lithium battery, and the magnesium battery has no explosion risk. This may be the battery that Samsung needs more. If a magnesium battery really can be produced in mass, lithium battery charger may be in the cold palace, that is, to spend less money to get more electricity, why not, is this excellent battery not worth being pick?
