Lead-acid batteries are generally composed of 3 or 6 single-cell batteries connected in series, consisting of plates, separators, electrolytes, shells, poles and filler plugs (no maintenance-free batteries). Lead-acid batteries 1. Plates of lead-acid batteries The pole plate is divided into positive plate and negative plate, both of which are composed of grid frame and active material. The purpose of the grid. The ladder has a secondary purpose, which will accelerate the precipitation of hydrogen and

Soft case Li-ion batteries are 40% and 20% lighter than steel and aluminum case Li-ion batteries. In terms of weight, soft-loaded lithium-ion batteries are much lighter than hard-loaded lithium-ion batteries, but the important weight ratio still depends on the weight of the box. different abilities Soft-pack lithium-ion batteries are 10% to 15% higher than steel and aluminum batteries, and 5% to 10% higher than steel and aluminum batteries. Although the capacity of soft-pack lithium-ion batteries is not much

As a core component of digital products and electric vehicles. Lithium-ion batteries in these products typically consist of multiple cells. During use, charge and discharge performance and battery life may be significantly reduced due to increased internal core temperature of the battery cells. Especially for power lithium batteries in the automotive field, accurate cell temperature estimation and monitoring are critical to the performance and life of the entire battery system.(Lithium - Ion Battery Equipment)

In 2018, Guoxuan Hi-Tech invested 493 million yuan in research and development. The research and development projects include: 22-platform lithium iron phosphate battery development, ternary battery development and industrialization, battery capacity design and manufacturing assurance technology, model-based battery design and There are 6 major projects including intelligent manufacturing technology development, technology to improve battery energy density, and 20 platform lithium iron phosphate battery development

Is hydrogen fuel-powered lithium battery a real black technology? Recently, BYD revealed to investors that it is developing hydrogen fuel-powered lithium batteries. In fact, in May, BYD struck a deal with an American company, Hybrid Electric Power, to collaborate on hydrogen fuel-powered lithium-ion battery buses. Not only BYD, it is understood that domestic companies Weichai Power and Great Wall Motors have successively deployed hydrogen fuel-powered lithium batteries. Japan's Toyota began research on hy

In recent years, the development of new energy vehicles has developed by leaps and bounds, and there is a tendency for latecomers to catch up. In the research and development process of new energy vehicles, whether it is the extended-range hybrid model Volt launched as early as 2010, or planned in 2023 Before the vision of launching at least 20 pure electric vehicles, GM has already placed new energy vehicles at the height of corporate strategic development. Whether it is a pure electric vehicle or a hybrid vehi

1. Electromotive force The electromotive force is the difference between the balance electrode potentials of the two electrodes. Taking lead-acid batteries as an example, E=Ф+0-Ф-0+RT/F*In(αH2SO4/αH2O). Among them: E—electromotive force Ф+0—positive standard electrode potential, its value is 1.690 Ф-0—negative standard electrode potential, its value is -0.356 R - universal gas constant, its value is 8.314 T - temperature, related to the temperature of the battery F

A subsidiary of LG Group is investing heavily in a U.S. R&D subsidiary to develop the fuel cell business, developing "solid oxide fuel cells," which LG says are third-generation fuel cells. It looks like LG Group is poised to continue pouring R&D dollars into new fuel cells, which it did last year and continue this year. Industry insiders pointed out on the 20th that LG Group subsidiaries LG Electronics, LG Chem, and LGCNS recently invested $38.4 million in LGPureCellSystems, a subsidiary of LG

The development of high-performance power batteries is one of the important measures to promote electric vehicles. Recently, the reporter learned from the second quarter regular press conference of the Chinese Academy of Sciences that the energy density of a variety of power battery cells developed by the Chinese Academy of Sciences has reached more than 300Wh/kg, ranking the world's advanced level; my country's power lithium batteries have entered the core technology. In the stage of large-scale applicatio
