What is a sodium battery? Which is better, a sodium battery or a lithium-ion battery? According to scientific research, sodium and potassium batteries are expected to replace traditional lithium-ion batteries. A sodium-based battery can store the same amount of electricity as a lithium-ion battery, which makes its manufacturing cost much lower than that of a lithium-ion battery, or it can replace a lithium-ion battery. Despite the price advantage, there is still a long way to go. What is a sodium battery? A sodium-based battery is a battery that combines sodium and inositol. It was developed by researchers at Stanford University in October 2017. In sodium ion batteries, sodium ions are attached to inositol, a common compound that can be extracted from the liquid by-products of rice bran or corn processing. The new combination of sodium ions and inositol significantly improves ion cycling in sodium-based batteries, allowing ions to move more efficiently from the cathode through the electrolyte to the phosphorous anode, resulting in a stronger current. The sodium in the new battery is combined with a compound called inositol, an organic compound that is common in household products including infant formula. Just as sodium is much more abundant than lithium, furfuryl alcohol is easily extracted from rice bran and can be found in the by-products of corn processing. This will help ensure that material collection is cost-effective. Which is better, sodium battery or lithium-ion battery? Lithium-ion battery is the core of new energy vehicle technology, but now there is a sodium-based battery that can store as much energy as the latest lithium-ion battery at a lower price. The price of materials accounts for a quarter of the price of batteries, the price of lithium is as high as US$15,000 per ton, and the price of sodium is US$150 per ton. Lithium-ion batteries have existed for 25 years and have dominated the market, but lithium has become more and more scarce, and the cost of mining has become higher and higher. To this end, scientists discovered that sodium can also store ions, making batteries cheaper and more powerful. One of the biggest obstacles to sodium-based batteries and potassium-based batteries is that they decay and degrade faster than lithium-ion batteries and have a lower energy density. But this is not always the case. When the researchers studied the reaction of lithium, sodium, and potassium ions with iron sulfide particles, they found that sodium and potassium were more stable in the reaction with iron sulfide, indicating that the life of sodium or potassium-based batteries may be much longer than expected. Sodium-based batteries may be a good alternative to lithium-ion batteries. Although the new sodium-based battery may never meet the needs of electric car manufacturers, the researchers believe that it will help store sustainable energy from solar panels and wind turbines. In the new design, sodium ions are attached to inositol, a common compound that can be extracted from the liquid by-products of rice bran or corn processing. The new combination of sodium ions and inositol significantly improves ion cycling in sodium-based batteries, allowing ions to move more efficiently from the cathode through the electrolyte to the phosphorous anode, resulting in a stronger current. In addition to comparing the cost and performance of lithium-ion batteries and sodium, the researchers also analyzed how sodium ions attach to the cathode during charging and discharging, which helps improve battery design. However, it is difficult to say whether sodium-based batteries can replace lithium-ion batteries, because sodium-based batteries are difficult to beat, and the cost is declining year by year. More importantly, funds are flooding into lithium mines and lithium-ion battery manufacturers. People pay more and more attention to the application value of sodium ion batteries. In recent years, sodium ion batteries have received extensive attention from the scientific community. The difference between lithium ion batteries and sodium batteries 1. Lithium ion batteries are charged and discharged by the movement and conversion of lithium ions between the positive and negative electrodes, while sodium ion batteries are charged and discharged by the insertion and ejection of sodium ions between the positive and negative electrodes. To carry out charge transfer. In fact, the working principle of the two is the same. 2. The ionic radius of the two is different, resulting in the performance of sodium ion battery is much lower than that of lithium ion battery; the negative electrode of lithium ion can make graphitization, while sodium ion is difficult to inactivate/intercalate in graphite, and the capacity is very small; The maximum processing capacity of other carbon materials is about 300 mA; the capacity of positive ions is very small, only a little over one hundred mA; the insertion/de-intercalation resistance of sodium ions on the positive and negative electrodes is very large, which is due to sodium ions. The radius is larger. Poor reversibility, and irreverse statement: Some pictures and content of articles published on this site are from the Internet.
