In response to the difficulties of the above two methods, this article proposes a micro short circuit diagnosis method for battery packs using the time and voltage during the charging process of the battery pack. Its advantage is that only the charging data of the battery pack is required, wit...

Abstract: Lithium batteries are widely used in new energy electric vehicles and energy storage due to their superior performance. However, the micro short circuit problem of lithium batteries is a safety hazard related to both vehicle and energy storage battery packs during use. In order to di...

It is understood that the battery consists of a negative electrode made of carbon fiber and a positive electrode made of aluminum foil coated with lithium phosphate. They are separated by glass fiber fabric, which serves as a structural electrolyte matrix. It can transport lithium ions between...

(Shanghai, Editor Huang Junzhi) - In today's electric vehicles or electronic devices, batteries account for a large portion of the weight of the device, but do not have any load-bearing function. Therefore, scientists have been exploring an alternative method to replace traditional energy...

At the same time, the strong entry of traditional chemical industry leaders has also brought variables to the future of the industry and opportunities for battery companies. The price difference between battery products and industrial products has widened, making the first two companies profit...

Methyl ethyl carbonate EMC is also an important solvent in lithium batteries, accounting for approximately 30% to 40% of the electrolyte, especially up to 70% in high nickel ternary battery electrolytes and liquid lithium salts. Overseas customers have a huge demand for EMC...

Higher requirements for battery performance CATL's involvement in the electrolyte process On December 9, 2020, the Longyan Municipal Government of Fujian Province announced the environmental impact assessment report of CATL's subsidiary, Times Sika...

Recently, after a fire and explosion incident at an energy storage power station in Beijing, experts in the battery industry said, "Battery manufacturers will increasingly pay attention to the electrolyte and solvent processes, because the electrochemical system in lithium batteries is a...

CATL Chairman Zeng Yuqun even admitted that within 3-5 years, what can be achieved in cars is not all solid-state batteries. Will Wei Lai be beaten in the face or prove himself, and it's up to time. However, in order to enhance the competitiveness of their new energy vehicle models, some d...

From naming to mass production time, technical route, comprehensive internal review Even when naming batteries, they need to accurately grasp the correct way. Before the emergence of BYD's blade batteries, people's understanding of the category of...
