One is to improve the infiltration of electrolyte, which is beneficial for the stability of battery performance;

In polar scientific research stations, high-altitude border outposts, aerospace deep space exploration, and industrial equipment in high-altitude regions, the low-temperature performance of batteries is often the key to determining the success or failure of equipment operation. Traditional lithium batteries face challenges such as capacity drops, inability to charge and discharge, and even permanent damage below -20 ℃. However, Tianqin New Energy Technology Co., Ltd. has successfully developed a lithium battery solution that can discharge stably in extreme low temperature environments of * * -50 ℃, redefining the technological boundaries of the industry through disruptive technological breakthroughs!...

Anti loss device is a device based on Bluetooth technology, mainly used to prevent the loss of items. The following is the working principle of the anti loss device:

The tortuosity represents the degree of curvature of the transmission path of porous electrodes, and is another important parameter related to transmission characteristics in addition to porosity.

The side reactions that occur during overcharging of lithium batteries are mainly different reactions of the electrolyte on the positive and negative electrodes. For positive electrodes, batteries with LiCoO2, LiMn2O4, or ternary materials as the main positive electrode materials are prone to decomposition reactions due to excessive delithiation of the positive electrode active material during overcharging, resulting in the generation of oxygen; More generally, due to high positive electrode potential and strong oxidation during overcharging, the electrolyte is prone to undergo oxidation and decomposition on the positive electrode, producing gas. Kumai et al. believe that the electrolyte will also react with the O2 decomposed from the positive electrode material and decompose to produce gas....

With the launch of an advanced zero emission hydrogen powered bus, Hong Kong's public transportation landscape is undergoing a revolutionary transformation. After the debut of Hong Kong's first electric double decker bus two years ago, the first hydrogen fuel double decker bus has been put into service on Hong Kong's Bus Route 20, marking a new step in Hong Kong's rich transportation history.
