As early as 2010, the concept of 'cobalt free' had already been proposed by Tesla. But until now, there has been no large-scale cobalt free battery market, and the proportion of battery technology has not increased. Why has "cobalt free" not been achieved yet? What exactly ar...

However, generally speaking, the actual capacity loss of waste batteries can rarely exceed 70%, so these batteries are usually utilized in a cascade manner, such as for low-end electric vehicles, electric tools, wind power generation and storage devices, etc., in order to achieve the reuse of...

The Nissan brand among the three Japanese brands has chosen to establish a joint venture with Sumitomo Corporation, 4REergy, to establish a factory specializing in the reuse and treatment of lithium-ion batteries for electric vehicles. The recycled batteries that cannot be reused will be conce...

Unlike other battery recycling institutions, Volkswagen recycles old batteries that cannot be used for other purposes. The recycling process no longer uses high-energy blast furnace smelting technology, but involves deep discharge and disassembly. The battery components are crushed into partic...

In recent years, new energy vehicles have developed rapidly and gradually become a new sales force in the market. However, at the same time, there is constant controversy among insiders and outsiders about whether electric vehicles are environmentally friendly. Among them, t...

Experts suggest standardizing battery maintenance and upkeep The frequent occurrence of spontaneous combustion in new energy vehicles has attracted widespread attention in the industry. Some experts have pointed out that in the past few years, especially i...

The balance between high energy density and safety of batteries In fact, Wang Chaoyang, director of the Electrochemical Engine Center at Pennsylvania State University, once gave a vivid example: as battery scientists and engineers, we play a game of compromise every day. The...

Thermal runaway becomes an important cause of spontaneous combustionAt present, it is widely believed in the industry that the main causes of thermal runaway in batteries are thermal radiation, internal short circuits in batteries, and abuse in harsh environments.According to the analysis and statis...

2. Regulations The transportation and management of hydrogen is a problem that troubles all governments that develop hydrogen energy. Hydrogen has always been a hazardous chemical, and high-pressure hydrogen is even more worrying to the public. Therefore, the safety of hydro...

3. High energy conversion efficiency of fuel power cells Fuel power cells can easily achieve an energy conversion efficiency of over 50%, while internal combustion engines find it difficult to break through the 40% threshold. 4. Cleaning...
