Who is better than lead-carbon batteries and lithium batteries?

Lead-carbon batteries and lithium batteries are environmentally friendly: Lithium batteries are becoming more and more environmentally friendly. However, lead-acid batteries have been used for 150 years and environmental problems have always existed, but they have been used all the time. Of course, many restrictive measures have emerged in recent years. Lead-carbon batteries are essentially a new type of lead-acid batteries, and lead has environmental problems. Environmental pollution is 100%. The total pollution of lead-acid batteries (lead smoke, lead dust, acid mist and wastewater) is about 1%. This number is not small, but in some areas it is much larger than this estimate. Regarding the cycle life issue: Of course, lithium batteries have longer lifespan and lead-acid batteries have shorter lifespans. Therefore, lithium batteries have a long service life, are expensive, and have low operating costs. Self-discharge rate: The self-discharge rate of lithium batteries is much lower than that of lead-acid batteries and cannot be compared with lead-acid batteries. Type Self-discharge rate/month alkaline manganese-zinc-zinc round battery 2% zinc carbon MnO2/Zn round battery 4% lithium ion MnO2 round lithium battery about 1% lithium ion MnO2 lithium button battery about 1% nickel-cadmium battery 35% nickel Metal hydride battery 35% lead-acid battery 20-30% voltage channel: lead-acid battery is 2V, lithium battery is 3.2v~4.8v, according to different types. Use maturity: Although I have a long history of using lead-acid batteries, it can also be said to be grandfather-level. But today, lithium batteries are more widely used than lead-carbon batteries. Commodity price: Because lead-carbon batteries are not used on a large scale, the processing cost is much higher than that of lead-acid batteries, but if they are used in large quantities, the processing cost will be lower. In the use of induction costs, the induction costs of the two batteries are not very different, and lithium batteries are more economical. One-time investment: Now, one-time investment costs. Lead-carbon batteries have the advantages of electric vehicles, and the price of the whole vehicle is cheaper than that of lithium batteries. Taking into account the life of lead-carbon batteries, it does not have many advantages. In short, the two types of batteries may be of different categories, can coexist for a long time, and give play to their respective advantages in the market. There is no incompatible situation, and there is no antagonistic relationship between lead-carbon batteries and lithium batteries. 1. Different materials: carbon ( Graphite is the negative electrode of a lithium battery, and the lithium-containing compound is the positive electrode; the positive electrode of a nickel-cadmium battery is composed of active materials such as nickel oxide powder and graphite powder, and the negative electrode is composed of active materials such as cadmium oxide powder and iron oxide powder. 2. Different working principles: Lithium battery is more like a rechargeable container and does not depend on electrochemical reaction at all. When the battery is charged, lithium ions are generated on the positive electrode of the battery, and the generated lithium ions move to the negative electrode through the electrolyte. Lithium batteries do not contain any toxic elements, have almost no impact on the environment, and are used in many digital electronic devices. The battery has low internal resistance and can adapt to high current discharge. It can be divided into low multiplier, medium multiplier and high multiplier batteries. Suitable for high power output. The difficulty of the battery at high temperatures is important to respect. The temperature of the Ni-MH battery is higher, and the reaction reaction oxygen component can accelerate the reaction. If there is a better negative electrode property, the split oxygen cathode and the negative electrode can be restored, thereby making the internal pressure of the battery Can be eliminated. When the battery is fully charged at a speed of 1C, the battery life can reach more than 500 times. In fact, in some developed countries, especially Japan and the United States, in the process of developing and industrializing electric vehicles, the most important choice for power lithium-ion batteries is nickel-hydrogen batteries. It is a device that converts the chemical energy of positive and negative active materials into electrical energy through electrochemical reactions. After long-term research and development, chemical batteries have ushered in a wide range of applications. Things as big as buildings can be accommodated, and things as small as millimeters can be accommodated. We are always serving our better lives. Many electrochemical scientists in the world are now very interested in the field of chemical batteries that power electric vehicles. The earliest batteries consisted of a glass container filled with electrolyte and two electrodes. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
