1、 The materials are different. The plates of power batteries are mostly lead-calcium alloy, and the starting batteries are mostly lead-antimony alloy. 2、 The discharge time is different. The power battery can discharge at low current for several hours, and the discharge d...

Australia and Chile are the two largest lithium mining countries in the world. However, due to different geological and climatic conditions, they have different ways of producing lithium. The Greenbushes mine in Western Australia supplies one-third of the world's lithium...

According to foreign media reports, scientists at the University of Arizona in the United States have developed a paper-based lithium-ion battery that can be folded in half or into Miura-ori type (similar to the map folding method) for many times. Since it becomes smaller after folding, the su...

According to the small editor, many consumers go to the place where they sell electric vehicle batteries and see too many battery brands, models and models. They are both lead-acid and lithium-ion batteries. They don't know which battery to choose? So what is the differe...

The coating process is divided into three parts: the first is the slurry feeding system, the second is the coating system, and the third is the polar drying system. The trinity requires that each system can maintain stability to ensure the consistency of the pole piece. This article will discu...

New energy vehicles have recently become a news hotspot. At the beginning of this year, the Ministry of Industry and Information Technology, the Ministry of Science and Technology, the Ministry of Environmental Protection and other seven departments jointly issued the Interim Measures for the...

"The country produces more than 5 million tons of waste lead-acid batteries every year. If it cannot be recycled scientifically, it will become a serious potential environmental pollution hazard," said Shi Yingjun, a deputy to the National People's Congress and mayor of Jiyuan Ci...

Although the power battery recycling market has a promising prospect and the recycling principle is also firmly established, in Wang Bo's view, the power battery recycling business is not easy to do. According to Yun Qiang, the cascade utilization and recycling of waste...

First of all, we can check whether there are bulges, leakage, burning and other abnormalities through the appearance. When the battery is obstructed and cannot be judged on time through the intuitive method, we need to conduct open-circuit voltage test and the capacity test of lithium-ion batt...

Lithium ion batteries can be divided into two categories, namely, lithium metal batteries and lithium ion batteries. The charging mode is basically CC/CV, which is also known as the conventional charging mode of lithium ion batteries. When lithium ion batteries fail to charge, there are no mor...
