Now give everyone some of the basic knowledge of lithium batteries.

Lithium-ion batteries consist of a positive electrode material, a negative electrode material, an electrolyte, a separator, and a supporting material. Both positive and negative electrode materials have the function of enabling lithium ions to reversibly move in and out. During charging, lithium ions migrate from the positive electrode material to the negative electrode to become a high-energy state, and when discharging, the opposite occurs, and in the external circuit, a current from the positive electrode to the negative electrode releases energy. During the charge and discharge, lithium ions are embedded and de-embedded on the positive and negative electrodes. Therefore, it is also compared to a rocking chair battery.

The development of cathode materials supports the progress of lithium-ion battery technology. The development of materials has led to the development of individual characteristics of battery performance, resulting in lithium-ion battery types suitable for different conditions. Lithium cobaltate is currently the most widely used cathode material, with features such as high open circuit voltage, high energy density, and long cycle life. Its lithium battery is mainly used in the field of digital communications products. However, the price of cobalt is high and lithium cobalt oxide is highly toxic, and it has entered a bottleneck. Lithium iron phosphate is currently the most promising cathode material, its low price, good thermal stability, no pollution, excellent charge and discharge cycle performance, and is expected to be used in the field of power batteries to provide power for electric vehicles. However, the technical threshold is high and the battery energy density is relatively small. Other materials include lithium nickel cobalt manganese oxide, lithium manganese oxide, lithium nickel oxide, and the like.

The general choice of negative electrode material has good cavities and can be well embedded in materials that deintercalate lithium ions. Mesocarbon microbeads (MCMB) are the most powerful of commercially available carbon negative electrode materials, with microscopically dense packing of materials, high electrode density, less side reactions of electrodes, and irreversible capacity loss. The modified natural graphite has also attracted attention due to its low price and excellent performance indicators, and has partially replaced the use of some MCMBs. Other anode materials also include nitrides, silicon-based anode materials, tin-based materials, novel alloy materials, and the like.

Electrolytes and separators are also a vital part of lithium-ion batteries. The reaction of the battery occurs at the two poles, respectively. In addition to providing the reaction environment and providing the reaction material, the electrolyte also conducts current to reduce the internal resistance. The quality of the electrolyte directly affects the performance of the lithium ion battery. Generally, the organic mixed solvent is used, and at least one organic solvent with low volatility, high dielectric constant, and a low viscosity and volatile organic solvent is used. At the same time, the solidification temperature of the electrolyte becomes the lower limit of the temperature used by the battery, and the use of the low temperature electrolyte can obtain a battery that can be used under minus 40 degrees cold conditions. The separator is used to divide the positive and negative electrodes of the battery, prevent the two parts from touching the short circuit, and allow the electrolyte to pass through. Due to the high porosity, lower electrical resistance, higher tensile strength, better acid and alkali resistance, good mechanical processing ability, and stability to aprotic solvents in polyethylene, polypropylene films, The products are widely used. The diaphragm is also a high-tech, high-value part of the product, and it also has a crucial influence on the safety performance of the product.

The latest polymer lithium-ion battery refers to a battery using a polymer as an electrolyte. No liquid electrolyte is used to avoid leakage of the organic electrolyte, and the all-plastic structure facilitates assembly. At the same time, it can effectively prevent the formation of metallic lithium and eliminate the hidden dangers of internal short circuits. The processing convenience of the polymer provides ample space for the battery's exterior design. The commonly used polymer electrolytes are solid polymer electrolytes and gel polymer electrolytes, the main difference being that the latter contains liquid plasticizers. From a performance point of view, the conductivity of the gel polymer electrolyte is improved by 2 orders of magnitude compared with the solid polymer, and has become a mainstream technology for such batteries.

In addition, since the working voltage of a single lithium battery is about 3.7V, it is necessary to design and manage the battery pack under different application requirements. Good design and management are the most critical factors for the long-term stable operation of the battery pack.

Plate non-damaged desulfator with Smart pulse, Simple and Safe, Restore your battery when charging.
Most of Electric vehicle use lead-acid battery bank(12V /6V /8V cells packed in Series)as the power source, The design lifespan of battery is 2~3 years, but actually the battery is usually failure after 6~12 months used which State-of-capacity gradually decline and even some scraped. Through analysis by cutting a large number of failure batteries, the battery water loss and sulfation is quite prominent. Such as the phenomenon of battery sulfation and water dehydration can be effectively inhibited to prolong the service life greatly up to 2 times.
EV Battery Charging Restorer is a new generation of high-tech products developed specifically for restoring Electric vehicle battery when it is charging every time, it utilizes the energy from the charger when charging, generating electronic smart pulse with special frequency to be resonance with the thick lead sulfate crystals in battery charging process. Under the disturbance by the specific frequency pulse, the recrystallization of lead sulfate can be prevented effectively

Product features:

1. The use of advanced electronic pulse repair technology, no-damaged eliminate battery plate sulfation crystal. Recovery of battery capacity, ensure the EV driving mileage is longer.
2. The connection with charger is simple, safe and convenient, and Smart Pulse Charging Restorer can be used in conjunction with the charger for each charging process. The problem of sulfation of the plate can be eliminated during every charging process.
3.It smartly identify 72V/60V/48V/36V battery bank Spec, automatically adapt to precise voltage, automatically adjust the restore electric pulse.This Battery pulse maintainer is suitable for the popular 72V~36V batteries of electric vehicles, buy a set, multi vehicles benefit in family.
4. A strict circuit filtering technique, does not repair your charger as a pulse, without changing the structure of the charger, does not affect the charging parameters of the charger, safe and carefree.
