As a   Ni-Cd Battery Pack Manufacturer , share with you. If this is not your first stop in NiCd information tracking, I believe that the information you read, hear or find on the Internet will make you at a loss. In this tutorial, we will do our best to keep it simple, accurate and realistic. If you have any unresolved issues, please let us know and hope we can help you. Ni-Cd Battery What is a nickel-cadmium battery? "NiCd" is the chemical abbreviation for nickel-cadmium batteries, which is a type of secondary (rechargeable) battery. Nickel-cadmium batteries contain chemical substances nickel (Ni) and cadmium (Cd) in various forms and compositions. Generally, the positive electrode is made of nickel hydroxide (Ni(OH)2), the negative electrode is made of cadmium hydroxide (Cd(OH)2), and the electrolyte itself is potassium hydroxide (KOH). Uniqueness of NiCd battery NiCad batteries differ from typical alkaline or lead-acid batteries in several key aspects. One of the main key

What are the Ten Advantages of Lithium Batteries for Electric Vehicles?

As an   Emergency Lighting Battery Supplier , share it with you. Ten advantages of lithium batteries for electric vehicles: Solar Lighting Battery Lithium 1. Long life of the circulation system: the charging output power of the lithium battery is 1c times, the service life of the circulation system is greater than or equal to 1500 times, and the volume exceeds 70% of the allowable difference of the copper beam. Even if the battery is charged, the cycle life of the rechargeable battery does not exceed 350 times and the volume does not exceed 60%. 2. Low-volume charge and discharge characteristics: Lithium batteries can be used in all normal operations, and their volume reaches 70% at -25c, while lead-acid batteries reach 50% at -10c, but not at -25c. 3. Powerful maintenance of differential signal polarization: The volume of the lithium battery charged by the battery reaches 80% or higher in two months, and the volume of the lead-acid battery reaches 40% to 50% in two months. 4. Working

What Damage Do Overcharge and Overdischarge Have to Lithium Batteries?

图片
It is often heard from   Emergency Lighting Battery Supplier   that lithium batteries cannot be overcharged or over-discharged, otherwise the lithium battery will be destroyed, so what is overcharge and overdischarge? What is the harm to lithium batteries? Overcharge: Overcharge means that when the lithium battery is overcharged, the battery charging working voltage exceeds the set working voltage, such as the rated current of the rechargeable battery, full battery ±. That is, the maximum working voltage is above 9V. If it exceeds 9V, it is called overcharge. What damage does overcharge do to the rechargeable battery? Solar Lighting Battery Lithium During overcharge, the battery voltage rises rapidly with the expansion of the polarization, which will cause irreversible transformation of the positive active material structure, which will cause the electrolyte of the lithium battery to dissolve, cause a lot of vapor, release a lot of heat, and greatly increase the battery temperature and
