What is the difference between power lithium battery and ordinary lithium battery?
1. Power lithium battery is a kind of rechargeable battery, as a special tool for displaying power in road transportation, generally compared with small and medium-sized rechargeable batteries, it shows the kinetic energy of carrying electronic products.
2. The battery capacity is different. Under all new rechargeable battery conditions, the battery capacity is measured by discharge, and the general power lithium battery capacity is 1000-1500mah. The capacity of ordinary lithium batteries is above 2000mAh, and some can reach 3400mAh.
3. The discharge power is different. A 4200mAh power lithium battery can discharge the power in just a few minutes, but ordinary lithium batteries can't do it at all, so ordinary lithium batteries cannot compare with power lithium batteries.
The principle of solid-state batteries is the same as that of ion batteries. The difference between solid-state lithium batteries depends on the choice of solid-state chemicals (such as polymers and inorganic materials, etc.) rather than lithium-ion batteries. Because it uses a solid electrolyte, it is called a solid battery. At present, it is still a popular liquid lithium ion, but the specific energy of liquid lithium ion is already a shortcoming and cannot meet the technical requirements. The safety of solid-state batteries is twice that of liquid lithium. The solid electrolyte has the advantages of non-flammability, non-evaporation, non-leakage, etc., and the solid-state battery will not have the diaphragm caused by the disconnection and short-circuit failure of lithium dendrites, and will not remove flammable and explosive materials. Therefore, many companies strive to study the next generation of solid-state lithium battery technology.
General lithium battery selection coating method must consider several levels: number of layers, wet coating thickness, rheological properties of the sizing solution, specified sizing accuracy, sizing body or sheet, and sizing rate. In addition to the above elements, it is important to integrate the details and characteristics of the film application. The coating characteristics of lithium battery electrode pole pieces are as follows: (1) Double-sided single-sided sizing; (2) Wet coating thickness of the slurry (100300m); (3) Non-Newtonian low-viscosity hydrodynamics of the slurry; (4) High-precision film sizing similar to film sizing; (5) Aluminum platinum and copper-plated film thickness is 1060m; (2) The film sizing rate is lower than the film sizing rate.
In recent years, lithium ions have been widely used in various fields. In order to improve the efficiency of lithium ions in the entire process, we must pay attention to many key issues. Next, let's talk about how to improve the life of lithium ions. 1. Not overcharged. Lithium batteries must be charged according to the battery charge c number required by the rechargeable battery or a lower c number.
2. The temperature is right. Lithium is generally not prone to safety accidents. The purpose of daily maintenance is to place lithium ions in an appropriate natural environment to delay the time of battery fragility. In fact, one of the main parameters of the lithium-ion design scheme is applicable to temperature. Relatively low temperature is not a problem, but if it is placed at a higher temperature, it is better and it will also cause safety hazards.
3. Suitable for natural environment. The natural environment suitable for daily maintenance of lithium ion should be four words: natural ventilation and coolness. These four words should be followed, regardless of whether the lithium ion is idle alone or on standby in the power supply.
4. Brand. At present, all kinds of lithium-ion battery products on the market are mixed, and choose the best possible situation to choose high-quality, high-quality brand-name lithium-ion.
5. Lithium battery charger. Please use the original brand or reputable charging head. The lithium battery needs to use a special lithium-ion charging head and follow the instructions, otherwise the battery will be damaged or even dangerous.
