For Ni-MH Battery, should the battery be discharged before being stored or stored under power?

图片
Which two different perspectives should be adopted? Many people think that the former should be adopted, but  Ni-MH Battery Packs Wholesaler  believes that the battery is more reasonable to keep it live. Because: According to tests, the best conditions for storage of nickel-metal hydride batteries are about 80% when charged. This is because the self-discharge of the  Ni-MH Battery  is large (about 10% -15% a month). If the battery is completely discharged and then stored, if it is not used for a long time, the self-discharge of the battery will cause the battery to overdischarge Will damage the battery. Do not believe? Then you think about whether the newly purchased Ni-MH rechargeable batteries still have electricity, which is the reason. Suggestion: make more comparisons, correct the wrong point of view, and start to maintain the battery from the right direction, otherwise it will be contrary to expectations. Ni-MH Battery Try not to discharge the NiMH battery. Overdischarge w

What happens if the Ni-MH Battery is not used for a long time?

Ni-MH Battery  consists of nickel hydroxide positive electrode, hydrogen storage alloy negative electrode, separator paper, electrolyte, steel case, top cover, sealing ring, etc. In a cylindrical battery, the positive and negative electrodes are wound together with a separator paper and then sealed in a steel case. In a square battery, the positive and negative electrodes are separated by a separator paper and stacked in a layered seal in a steel case. Hydrogen batteries use nickel hydroxide as the positive electrode, hydrogen storage alloy as the negative electrode, and potassium hydroxide solution as the electrolyte. Ni-MH Battery If it is not used, it will be discharged at a rate of 0.2% -0.3% every day, and after a period of storage, even if it is not recycled, a small part of its capacity will be permanently lost, and its life will also decline. Therefore, the battery should not be stored for more than one year. As a  Power Tool Batteries Supplier , let me share with you

Do you know the characteristics and applications of LiFePO4 Battery?

Features of  LiFePO4 Battery 1. High energy density 2.Good safety performance The electrochemical performance of LiFePO4 Battery cathode material is relatively stable, which determines that it has a stable charge and discharge platform. Therefore, the structure of the battery will not change during the charge and discharge process, and it will not burn and explode. It is still very safe under special conditions such as extrusion and acupuncture. 3.Long cycle life The cycle life of LiFePO4 Battery1C generally reaches 2,000 times, or even more than 3500 times, while the energy storage market requires more than 4000-5000 times, ensuring a service life of 8-10 years, which is higher than the cyclic life of the ternary battery more than 1,000 times, and The cycle life of long-life lead-acid batteries is about 300 times. 4. Safety and environmental protection LiFePO4 Battery does not contain any heavy metals and rare metals. It is safe, non-toxic and non-polluting. It is an ab

Do you know how to repair Ni-Cd Battery?

As a  Ni-Cd Battery Pack Supplier , share the information with you. Nickel-cadmium battery is an older battery. Because its substrate material uses heavy metal cadmium, it will seriously pollute the environment. Therefore, the production and use of this battery have been stopped. In some occasions, it is basically the inventory of previous years and Foreign garbage from abroad. Compared with nickel-cadmium batteries, nickel-metal hydride batteries no longer use toxic heavy metals and are one of the mainstream battery types. If you compare them from the same specifications, the performance of nickel-cadmium batteries and nickel-metal hydride batteries is basically the same, that is, the "power" is basically the same. However, in view of the fact that nickel-cadmium batteries are currently in stock or foreign garbage, their performance is far inferior to that of newly-produced nickel-metal hydride batteries. Therefore, generally speaking, nickel-metal hydride batteries are bet

Is Lithium Iron Phosphate Battery safe?

Now, people buying new energy vehicles objectively choose between  Lithium Iron Phosphate Battery  and ternary lithium battery technology. People in the industry tell us: the ternary system that emphasizes the endurance and light weight of the vehicle. Lithium iron phosphate is selected for safety. In this regard, consumers are eager to give the industry a practical answer from a technical point of view: Is lithium iron phosphate battery safe? This question should be answered in terms of material/structural stability, production process, and charge and discharge characteristics. During the charging process, part of the lithium ions in the lithium iron phosphate are extracted, transferred to the negative electrode through the electrolyte, and embedded in the negative carbon material; at the same time, electrons are released from the positive electrode, and the negative electrode is maintained from the external circuit to maintain the balance of the chemical reaction. First, as a  L

Ni-MH Battery  is a good performance battery. Nickel-metal hydride batteries are classified into high-voltage nickel-hydrogen batteries and low-voltage nickel-hydrogen batteries. The positive electrode active material of the nickel-hydrogen battery is Ni(OH)2 (called NiO electrode), the negative electrode active material is metal hydride, also called hydrogen storage alloy (electrode called hydrogen storage electrode), and the electrolyte is 6 mol/L potassium hydroxide solution. Nickel-hydrogen batteries have become more and more important as an important direction for hydrogen energy applications. Ni-Cd Battery Ni-Cd Battery  is an alkaline storage battery. Its positive plate is nickel hydroxide, the negative plate is cadmium, and the electrolyte is potassium hydroxide or sodium hydroxide solution. Nickel-cadmium batteries contain a large amount of Ni, Cd and Fe, among which Ni is an important raw material for steel, electrical appliances, non-ferrous alloys, electroplating, et
