Speaking of lead-acid batteries, the first application we can think of is electric bicycles. In fact, according to its structure and use, the industry's lead-acid batteries are divided into four categories: 1, start-up 2, power use 3, fixed valve-controlled seal type 4, small valve-controlled seal type. As a  Replacement Power Tool Battery Supplier , our method is mainly classified from the structural aspect, and we want to balance the use. It is difficult for non-battery practitioners to understand. If it is classified from the perspective of pure market application, it is better. Understand, according to this standard, lead-acid batteries are divided into two categories: 1. Main power supply, including: communication equipment, industrial equipment, power control machine tools, portable equipment; 2. Backup power supply, including: emergency equipment, communication base station, electronic switch system, solar energy system. This type of application has many intersections w...

Grasp the time and prevent overcharge. Doing the right thing at the right time, although the lithium battery itself has excellent electrochemical performance, however, any kind of thing will have safety hazards after deviating from the equilibrium state. As a  Li-ion Battery Manufacturer , let's give you a detailed introduction. 1. When charging, charge. In the early days of smartphones, each mobile phone manufacturer often emphasized the use of original chargers (including charging cables) to charge consumers with power out of their original interests. Some manufacturers design special data lines and do not support other devices. Charger (including charging cable). Later, with the increasing use of smartphones and laptops, it is obviously self-restraint, so now everyone has unified the standard, a charger/line can charge different brands and nature of electrical appliances. It is convenient to charge, and one problem that users should pay attention to is to keep the battery wit...

As a  Lithium Battery Pack Supplier , let's analyze the cause of the explosion of a lithium battery: 1. Internal polarization is large; 2. The pole piece absorbs water and the echo drum is generated with the electrolyte; 3. The quality of the electrolyte itself, the performance title; 4. The amount of liquid injection during the injection time does not meet the process requirements; 5. The laser welding and welding sealing performance is poor in the process of the device, and the air leakage is measured. 6. Dust, extreme dust is easy to cause micro-short circuit, the cause of the cause is unknown; 7. The positive and negative electrode sheets are thicker than the process area, and it is difficult to enter the shell; 8. The title of the liquid injection seal, the bad performance of the steel ball seal leads to the air drum; 9. The shell material has a thick shell wall, and the shell deformation affects the thickness; Our company provides  Lithium Battery ...

As a  Black&Decker Battery Supplier , let's talk about the maintenance of lithium batteries. Lithium battery cells will begin to produce side effects when they are overcharged to a voltage higher than 4.2V. The higher the overcharge voltage, the higher the risk. After the lithium battery voltage is higher than 4.2V, the amount of lithium atoms remaining in the positive electrode material is less than half. At this time, the storage cell often collapses, causing a permanent drop in battery capacity. If the charging continues, since the cell of the negative electrode is already filled with lithium atoms, the subsequent lithium metal will accumulate on the surface of the negative electrode material. These lithium atoms grow dendrites from the surface of the negative electrode toward the direction of lithium ions. These lithium metal crystals pass through the separator paper, shorting the positive and negative electrodes. Sometimes the battery explodes before the short circuit...

For new energy vehicles, the battery has always been the core part of the whole vehicle. However, for the battery, it is still in a development period until now, so each car company will develop different types of batteries according to its own model, the most What people are confused about is the hybrid battery type. Toyota is still choosing NiMH batteries when everyone recognizes the largest capacity of lithium batteries. Why? As a  Festool Battery Factory , let's analyze it. First of all, the battery is tens of thousands of species, the first safety. The reason why NiMH batteries can be the first choice for Toyota Hybrid is because it has unparalleled safety performance. Why do you say this? On the one hand, the electrolyte in the nickel-hydrogen battery is a non-flammable aqueous solution. On the other hand, the specific heat capacity of the nickel-hydrogen battery is relatively high, and the energy density is relatively low, which means that the nickel-hydrogen battery is e...
