In a narrow sense, ternary materials refer to stoichiometric nickel-cobalt-manganese three-component layered cathode materials. This type of material was first developed by Chinese scholar Liu Zhaolin in 1999 at the Institute of Materials Research and Engineering (IMRE) affiliated to A-Star in Singapore. ) was reported when I was working on it. Since then, many international research groups have conducted very detailed and in-depth research on this series of materials. In a broad sense, the scope of ternary mate

Recently, Zhang Yuegang's research group at the Suzhou Institute of Nanotechnology and Nanobionics, Chinese Academy of Sciences independently developed and designed an in-situ scanning/transmission electron microscope electrochemical chip, which enabled real-time observation of the charging process of lithium sulfide (Li2S) electrodes; in fully understanding Li2S charging Based on the discharge mechanism, a high-nitrogen-doped graphene-loaded lithium sulfide material was designed as the battery cathode. By cont

Since March, there have been 7 or 8 electric vehicle battery fire incidents in China, bringing the issues of battery safety and battery management system safety to the forefront. In these fire incidents, the temperature of the power lithium battery was uncontrollable and rose linearly after being heated, which led to combustion and explosion. This phenomenon has a professional term called thermal runaway of power lithium batteries. The rise in battery temperature is the culprit of fire and combustion, and the re

The famous journal "Science" published an academic paper by the my country University of Geosciences (Wuhan) research team on the 10th, announcing that through the electronic state characteristics of the semiconductor heterogeneous interface, protons are confined at the heterogeneous interface, and a proton channel with a low migration barrier has been designed and constructed. This reporter learned on the 10th from my country University of Geosciences (Wuhan). Associate Professor Wu Yan of the School

The development of new energy and electric vehicles will use lithium-ion batteries with relatively high energy density. When lithium-ion batteries are used in series, in order to ensure the consistency of battery voltage, a voltage balancing circuit is inevitably used. Today I would like to share with you some battery balancing circuits that I have used in my work. I hope it will be helpful to you. The simplest balancing circuit is load consumption balancing, that is, a resistor is connected in parallel to each

With the continuous deepening of my country's informatization construction, the rapid advancement of industry, and the continued development of the Internet of Things, AI, and 5G, all walks of life are thriving. At the same time, the rapid development of these industries has also strongly promoted the development of the power supply industry. my country's power supply industry market is facing opportunities as well as challenges. At present, the level of information construction and scientific and techno

Since the emergence of all-solid-state lithium-ion battery technology, researchers from various countries have expressed great interest in research. The research content has gradually extended from the initial battery charging and discharging principles to battery design, high-performance solid-state separator materials, etc. category, and many world-famous electronics companies such as South Korea's Samsung Electronics have also begun to organically combine all-solid-state lithium-ion battery technology with t

Current status of use of lithium-ion battery energy storage technology At present, countries around the world have invested a lot of manpower and material resources in the research of large-scale battery energy storage technology. In recent years, a large number of large-scale battery energy storage power stations have continued to be built at home and abroad. Western countries represented by the United States have invested heavily in the construction of large-scale battery energy storage power stations in recen

Square lithium-ion battery Square lithium-ion batteries usually refer to aluminum-shell or steel-shell square batteries. The popularity of square batteries is very high in China. With the rise of automotive power lithium-ion batteries in recent years, the contradiction between vehicle mileage and battery capacity has become increasingly prominent. Domestic Power lithium-ion battery manufacturers mostly use aluminum-shell prismatic batteries with higher battery energy density, because the structure of prismatic b
