LR03 battery

　　LR03 battery are the best choice among portable batteries

　　The birth of LR03 battery began with the discovery of the element "lithium". In 1817, Swedish chemists extracted lithium from an ore sample on a Swedish island for the first time. The name lithium is inspired by the Greek word for stone or stone. Although it sounds "heavy", in fact "lithium" is the lightest solid element currently known.

　　Everyone must have memorized the chemical periodic table by heart in middle school. From the chemical periodic table, we can know that the relative atomic mass of lithium is, belonging to the first group or the second period, and is the metal activity among known elements (including radioactive elements). Sex is the strongest. When I was in high school, my teacher did an experiment. If a piece of lithium is thrown into water or exposed to the air, it will burn quickly.

　　How did the lithium element become an indispensable lithium battery in contemporary life because it is so unstable?

　　To become a good energy carrier, it must store and transport more energy with the smallest possible volume and weight. The transformation from lithium element to lithium battery is due to the three characteristics of lithium battery

　　1: The relative mass of lithium atoms is small

　　2: Strong ability to gain and lose electrons

　　3: High electron transfer ratio

　　From these three points, you can draw conclusions from the periodic table. The elements above are better than the elements below, and the elements on the left are better than the elements on the right. Of course, someone will definitely say at this time, according to what you said, shouldn't hydrogen be the best energy carrier? Of course, I do not deny that hydrogen is the best energy carrier in nature. Otherwise, why would the research on hydrogen fuel cells be in the ascendant? Hydrogen can only be said to be the frontier of future development, and the current technology is not yet mature.

　　Therefore, choosing lithium as a battery is based on the relatively optimal solution we can find among all the current elements on the earth.

　　Advantages of LR03 battery (analysis based on mobile phones and electric vehicles)

　　1. High energy. Small size and large capacity. Take mobile phones as an example. The mobile phone battery is so small in size but can store a large capacity of 4000mAh.

　　2. Long service life. Mobile phones need to be charged every night, and the number of charge and discharge times is very high, but LR03 battery can achieve more than thousands of charge and discharge times.

　　3. The rated voltage is high, and the single working voltage is or, which is suitable for the use of small electrical appliances.

　　4. With high power endurance, lithium iron phosphate lithium-ion batteries can achieve a charge and discharge capacity of 15-30C, which facilitates electric vehicles to achieve high-intensity startup acceleration. This is why electric vehicles generally accelerate from 100 meters to 100 meters very quickly.

　　5. The self-discharge rate is very low, generally less than 1%/month. When the mobile phone is turned off, it will still have power for a long time.

　　6. It is light in weight, making mobile phones easier to carry and making electric vehicles lighter and faster.

　　7. It has strong adaptability to high and low temperatures and can be used in environments ranging from -20°C to 60°C, which is basically in line with our living temperature (this is why mobile phones freeze and shut down when it is -30°C in the Northeast)

　　Based on these 7 advantages, LR03 battery can be so popular in life. Electric car giants like Tesla rely on LR03 battery to create environmentally friendly cars, and battery manufacturers rely on LR03 battery to make equipment portable.

　　The purpose of the Nobel Prize is to award people in the world who have made the most significant contributions to mankind in the six fields of physics, chemistry, physiology or medicine, literature, peace, and economics.

　　Nowadays, we can carry a mobile phone weighing less than 150g when going shopping.

　　LR03 battery are not perfect. Taking mobile phone equipment as an example, the size of LR03 battery has been compressed to the extreme. In the tiny space of mobile phones, where every inch of land is precious, how to achieve small size and large capacity? When can mobile phones be charged once a month? , these will be solved one by one in the future. If nuclear fission technology can achieve major breakthroughs in the next few decades and can be miniaturized or even miniaturized, then portable nuclear fuel cells will have broad room for development.

　　However, it is undeniable that LR03 battery have indeed made great contributions to mankind in the field of chemistry, and LR03 battery are still the best choice among portable batteries.
