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...

1. High energy density The energy density of hydrogen is three times that of gasoline, and currently 40 times that of lithium-ion batteries. High energy density allows cars to travel ultra long distances even with only a small amount of hydrogen. During transportation, more...

At present, the price of this machine is around 1600 yuan, and its cost-effectiveness is also very high. And for over 2000 yuan, it will definitely be the first to launch the Void Divine Machine Red Rice K30S Ultimate Edition. The Snapdragon 865+5000mAh large battery and 144HZ 7-speed variable...

The larger the battery capacity, while ensuring sufficient basic configuration, the more I prefer this phone. And yesterday, many fans also hoped that Xiaozhi could recommend several reliable large battery phones. The larger the battery capacity, the better. This way, playing with the phone fo...

Friends who are familiar with the automotive industry know that the Japanese automotive industry's plans and prospects for solid-state batteries were the first to begin. At the same time, Toyota has always maintained a positive attitude towards new technologies and has long publicly announced it...

If there are any shortcomings in the development of electric vehicles to this day, it is that the development of electric vehicle battery technology has not broken through the bottleneck, and the charging speed is too slow. Even if the vehicle's range is high, the problem of difficult to c...

What lessons should China learn from the large-scale recycling of modern electric vehicles? This new structure significantly improves volume utilization by skipping modules when grouped, ultimately achieving more battery cells in the same space. Compared to traditional modul...
