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...

1. Differences in conceptual nature Lithium ion battery: It is a kind of battery with lithium metal or lithium alloy as negative material and non-aqueous electrolyte solution. It depends on the lithium ion moving between the anode and the cathode. In the process of charging...

1、 Lithium-ion battery pack assembly process Object/raw material: positive material, negative material, barrier paper Pace/essentials ① Pulping: Special solvents and adhesives are used to separate the powder of positive and...

With regard to the advantages and disadvantages of lithium-ion battery UPS, our usual practice is to use professional measuring instruments for identification, but this special instrument is not available to ordinary users. The steps are as follows: ① In fact, the key is ve...

Some studies have found that when lithium ion batteries are rapidly charged at ambient temperatures below 50 degrees Celsius, the battery activity will decrease. During the charging process, if the lithium-ion battery is continuously heated at a high temperature of 140 ℃ for 10 minutes and th...

Researchers at Deakin University in Australia have shown that they have now managed to use common industrial polymers to produce solid electrolytes, thus opening the door for doubling the energy density of solid-state lithium-ion batteries, which will not explode or catch fire when overheated....
