  As an   Emergency Lighting Products Manufacturer , share the difference between lead-acid batteries and lithium batteries. Currently, most electric vehicles on the market use lead-acid batteries. Its main features are. Reliable stability and mature technology. And can be recycled. In simple terms it is more economical. The depreciation price of the old battery recycling, the price advantage of the new battery is more obvious. Solar Lighting Battery Lithium The disadvantage is that the quality and volume energy density of traditional lead-acid batteries are relatively low. The energy density is only about 1/3 of that of lithium-ion batteries and about 1/2 of that of nickel-hydrogen batteries, and the volume is relatively large. For occasions. The traditional lead-acid battery has a short cycle life, and the theoretical cycle number is about 1/3 of that of a lithium ion battery. There is still much room for improvement of the cycle life of lead-acid batteries, especially lead-acid batt

  As a   LiFePO4 Battery Supplier , share with you. The interior of a lithium-ion battery is mainly composed of a positive electrode, a negative electrode electrolyte, and a separator. The positive, negative electrode, and electrolyte of a lithium-ion battery will have different performances and different names depending on the materials used. At present, the more common lithium batteries on the market are divided into LiCoO2 and LiMn2O4, and the main character LiFePO4 in this article. LiFePO4 Battery As a type of lithium battery, the main use of lithium iron phosphate is in the field of power systems, such as electric vehicles, military aerospace, power tools, and UPS. Due to its excellent structural stability, safety performance and long service life, it is more suitable Used in the field of power systems. Compared to lithium-ion batteries using other cathode materials,  LiFePO4 Battery  has at least five advantages. 1. Safety and Longevity Compared to the more common lithium cobalta

  Now that lithium battery technology is so developed, why do electric shavers and electric toothbrushes use   Ni-MH Battery   in large quantities? As a   Ni-MH Battery Packs Wholesaler , share with you. Ni-MH Battery 1. Cost problem The  Ni-MH Battery  used in the shaver is a mature Ni-MH battery that has been produced for more than ten years. After a long period of production, it can now achieve a relatively low cost. Although lithium batteries are cheap, they are still more expensive than nickel-metal hydride batteries. The important parts on the shaver are the motor and the cutter head. The motor is more sensitive to the current. The voltage and discharge characteristics of lithium battery and nickel metal hydride and nickel cadmium are different. When you produce, older motors either have mature production lines or have sufficient suppliers, which is cheaper. If you change a new battery, you have to replace it with a new motor. However, whether you design or produce the new motor

  As an   Emergency Lighting Battery Supplier , share with you. The durability of the battery has always been a problem for researchers, because no matter how large the battery's capacity is, it doesn't make sense if it can't be recharged multiple times. We all know that lithium batteries will decrease in capacity with use, but no one has ever known why. Recently, the United States Energy Agency has discovered the cause of battery aging: nano-sized crystals.  Scholars have carefully studied the materials of the anode and anode of modern batteries, and they found that these materials will be directly corroded during use, but the mechanism of corrosion has not yet been clarified. Brookhaven National Laboratory's team observed high-quality nickel-oxygen cathodes with a transmission electron microscope and recorded their changes during repeated charge and discharge.  Ni-Cd Battery This experiment shows that when lithium ions pass through the cathode and anode, they will &qu

As an  Emergency Lighting Battery Supplier , share with you. Ni-Cd Battery Advantages of  Ni-Cd Battery : high efficiency. Light body, long driving range, and strict requirements for user use and maintenance. Disadvantages: high price, uneven domestic lithium battery technology, lithium batteries used in electric vehicles have safety risks. Lead-acid batteries Advantages: high cost performance. Relatively cheap battery, large capacity, multiple battery choices, and mature technology. Disadvantages: low efficiency. The battery pack is bulky, which leads to the weight of the vehicle body, the driving mileage is short, and the battery needs scheduled maintenance. Overall Lithium batteries are still better. Hope my answer can help you. Nickel-cadmiumbattery A kind of alkaline storage battery whose positive active material is mainly made of nickel and negative active material is mainly made of cadmium. The positive electrode is nickel hydroxide, the negative electrode is cadmium, a
