Researchers from Rice University in the United States said that the electrolytic capacitor has excellent performance like a supercapacitor and can maintain a high battery capacity of 76% after thousands of charges and discharges or thousands of bends. James Tour, a chemistry professor at Rice University in the United States, and his colleagues recently developed an electrolytic capacitor that is thinner than paper. It is reported that this electrolytic capacitor has the characteristics of flexibility and large b

As a device that converts chemical energy into electrical energy, the battery has developed from the "Leyden Jar" in 1746 to the present, and has been divided into nearly 20 categories. In recent years, new batteries that have attracted market attention have emerged one after another. For example, hydrogen fuel-powered lithium batteries can generate electricity with near-zero carbon emissions by separating electrons in hydrogen gas and generating electric current. Many governments and automobile compan

Proton exchange membrane fuel-powered lithium battery (pEMFC) is a power generation device with the advantages of high specific power, high energy conversion efficiency, low-temperature start-up, and environmental friendliness. In recent years, it has still been a research hotspot in the field of fuel-powered lithium batteries. Its core component, the membrane electrode (MEA), is usually prepared by a hot pressing process from a gas diffusion layer, a catalytic layer and a proton exchange membrane. Key materials su

The vertical methanol fuel-powered lithium battery (DMFC) is a power generation device that converts the chemical energy stored in the fuel methanol solution and the oxidant (oxygen or air) vertically into electrical energy. Its significant advantages are: abundant sources of methanol fuel and low cost. The energy density is high. When the battery is working, the fuel is fed straightly without reforming. The structure is simple, the reaction time is short, the operation is convenient, and it is easy to carry and st

Lithium-ion batteries are an ideal power source due to their high operating voltage, small size, light weight, no memory effect, no pollution, small self-discharge, and long cycle life. In actual use, in order to obtain a higher discharge voltage, at least two single lithium-ion batteries are generally connected in series to form a lithium-ion battery pack. At present, lithium-ion battery packs have been widely used in notebook computers, electric bicycles and backup power supplies. Therefore, how to use the lithi

Lithium-ion batteries are representatives of modern high-performance batteries and are composed of four important parts: positive electrode material, negative electrode material, separator, and electrolyte. Among them, the separator is a thin film with a microporous structure. It is the key inner component with the most technical barriers in the lithium-ion battery industry chain. It plays the following two important purposes in lithium-ion batteries: a. Separating lithium-ion batteries. The positive and negative e

The length of battery life depends on two reasons. The first is that there are quality problems in itself, resulting in reduced performance and short usage; the second is that car owners usually do not know how to take care of the battery and wear out the battery. How should batteries be used to maximize their use and extend their lifespan? Kuai Kian Momentum has compiled 12 relevant experiences: 1. Resolutely do not use inferior chargers, and resolutely do not use chargers with mismatched models. The charger te

The so-called battery is an electrochemical device that stores chemical energy and releases electrical energy when necessary. It uses a lead-based grid filled with sponge lead (also called a grid) as the negative electrode, a lead-based grid filled with lead dioxide as the positive electrode, and dilute sulfuric acid with a density of 1.26--1.33g/mlg/ml as the electrolyte. When the battery is discharging, metallic lead is the negative electrode and undergoes an oxidation reaction to produce lead sulfate; lead dioxi

In the field of lithium-ion batteries, due to the uncertainty of the impact of various parameters on battery performance, experimental design has a certain degree of blindness. The traditional exhaustive method to determine parameters has the disadvantages of heavy tasks, low efficiency, and is difficult to solve theoretical problems. With the development of simulation technology, simulation technology has been applied to the research and development of more and more scientific research fields. As a complementar
