Core tips: lithium batteries for new energy storage devices The lithium battery uses carbon materials as the negative electrode and lithium containing compounds as the positive electrode. There is no metal lithium, only lithium ion. It is a secondary battery (rechargeable battery). It mainly depends on lithium ion moving between the positive and negative electrodes to work. In the process of charging and discharging, Li+is embedded and de-embedded between the two electrodes: during charging, Li+is de-embedded fr

With the development of science and technology, lithium batteries have become the mainstream and are mainly used in power lithium batteries and energy storage in emerging fields. In 2019, the global lithium battery industry market scale reached 49.3 billion US dollars, China's about 18.4 billion US dollars, Japan's about 14.9 billion US dollars, and South Korea's about 13 billion US dollars. The following is the meaning and classification analysis of lithium battery industry. China, Japan and South K

The research team of Professor Wu Yongzhen and Professor Zhu Weihong of East China University of Science and Technology has made new progress in the preparation of large-area hole extraction layer for perovskite batteries. Relevant research results were recently published in Advanced Functional Materials. Perovskite solar cells are one of the frontier and hot topics in the field of energy research at present. The maximum photoelectric conversion efficiency of small area devices in its laboratory has reached 25.2

The sales volume of domestic electric vehicles has increased significantly. According to the forecast report, the lithium ion power battery market is entering the golden period, and the scale of power lithium battery industry will increase sharply. With such leapfrog scale rise, battery quality has become a focus of attention. Some insiders believe that how to break through the technical bottleneck and extend the service life of the battery is a common issue faced by the current battery production companies. Bei

For researchers, battery technology is always a difficult problem to overcome completely. On the one hand, they should try to reduce the cost of manufacturing batteries and provide satisfactory battery life. On the other hand, they should ensure the safety of batteries. They are located in the electronic devices that consumers often use on weekdays, which means that accidents such as battery explosion should never happen, Because it may cause serious harm to human body.(Lithium - Ion Battery Equipment) Although

Zhang Huamin and Li Xianfeng, researchers of the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, led the team to make new progress in the research of non-fluorine porous ion conducting membranes for liquid flow batteries. Cross-linked network structure was introduced into the pore structure of non-fluorinated porous ion-conducting membrane, which greatly improved the selectivity and stability of non-fluorinated porous ion-conducting membrane under the operating environment of liquid flow battery.

The executive meeting of the State Council held on February 24th determined measures to further support the new energy vehicle industry and promote green development through structural optimization. The meeting proposed to accelerate the realization of revolutionary breakthroughs in power lithium batteries. Insiders in the chemical industry pointed out that the battery revolution is also an innovation revolution in related electrode materials, electrolyte and other chemical materials, which is both an opportunity a

On November 26, before the launch of a Huawei mobile phone, it was reported that the phone used graphene batteries. Affected by this, graphene concept stocks led the market higher on the same day. Although Huawei later confirmed that mobile phones did not use graphene batteries, there is still huge room for imagination about graphene batteries in the capital market. However, many scholars believe that it is difficult to break through various technologies at present. The real graphene is still a product in the la

In case of short circuit and overheating, lithium battery is very easy to explode out of control, which is why we advocate users to use original battery, charger and data cable to prevent short circuit of lithium battery. Smart phones have made considerable progress in recent years. The more powerful processors, graphics cards, ultra-clear and even flexible screens are impressive. However, the breakthrough in battery technology is slow, and we still have to endure about a day's endurance. Although we have be
