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

Fuel power cells directly convert chemical energy (fuel) into electrical energy. They have the advantages of high efficiency and low pollution. In recent years, they have received great attention from all aspects. Molten carbonate fuel cells (MCFC) operate at high temperatures (about 650C) and can use exhaust waste heat and gas turbines to generate electricity. Therefore, they have higher efficiency and are one of the mainstreams of current fuel cell research. Many achievements have been made in MCFC fuel power

Lithium-ion battery manufacturers briefly talk about the advantages and material research of all-solid-state secondary lithium-ion batteries. As the most potential electrochemical energy storage device, all-solid-state lithium-ion batteries have received widespread attention in recent years. With the improvement of comprehensive technical indicators such as cyclability and safety, the application market of solid-state secondary lithium-ion batteries will gradually expand, and all-solid-state lithium-ion batteries a

The principle of fast charging of lithium-ion battery charger, how is the battery fast charging technology achieved? In today's era, people are increasingly pursuing efficiency and speed. This concept of efficiency is multi-faceted. Now that there are more and more lithium-ion battery products, many people are also concerned about the charging speed of lithium-ion batteries. In order to meet this demand of people, many lithium battery companies have invested money and energy in fast charging of lithium batterie

Lithium-ion battery manufacturers introduce the service life and technical status of lithium titanate batteries. Lithium titanate material is used as the negative electrode material of lithium-ion batteries. Since the industrialization of lithium-ion batteries in 1991, the negative electrode materials of batteries have been dominated by graphite. In recent years, with the development of new lithium-ion batteries, domestic and foreign researchers have conducted in-depth research on the characteristics of lithium tit

A brief analysis of the urgent need for lithium-ion battery manufacturers to master the core technology of power lithium-ion batteries. The perfection of my country's power lithium-ion battery industry is second to none in the world. Even if it occupies a place in the world in terms of new energy vehicle ownership and market, if it does not master the real core technology, my country's power lithium-ion battery industry will only be small. Strong, in order to prevent the development of power lithium-ion bat

The design of the battery thermal management system is the key to improving the life of lithium-ion batteries. Thermal management of lithium-ion battery systems is an indispensable link to ensure battery safety, extend battery service life, and improve battery system performance. With the leap-forward development of new energy vehicles in recent years, the capacity and size of lithium-ion battery cells have gradually increased, and high-power operating conditions have gradually increased, which has brought severe c
