Phased progress has been made in energy density solid-state lithium batteries. In terms of industrialization demonstration of high-energy-density, high-safety deep-sea solid-state lithium batteries, the company has conquered the key core technologies of deep-sea long-endurance power supplies, and has achieved the 11,000-meter pressure chamber test. And the whole deep-sea demonstration application, boosting the national deep-sea power supply to a new height.（Lithium - Ion Battery Equipment） The fire accidents of

The University of Bologna in Italy released news that after 8 years of hard work, researchers at the school have developed a new semi-solid oxygen flow lithium battery NESSOX. With an energy density of up to 1 MWh/ton, it can be recharged in minutes by replacing the liquid electrolyte inside the battery, just like a car "refueling". The battery uses a new type of liquid electrolyte, which can effectively inhibit the formation of substances that cause battery failure and maintain stable battery performance

Not long ago, Zhao Zhongwei, deputy dean of the School of Metallurgy and Environment of Central South University, and his team "packed" a container full of "black technology" equipment, and "tugged a box with a port" from Changsha, Hunan to "Golmud," Qinghai. A huge "black box" container with several water pipes that can "turn decay into magic". The local salt lake brine with high "magnesium-to-lithium ratio" entering the "black box"

EnergyTrend, a new energy research brand under TrendForce, said in a report that, under the influence of China's new energy policy, the demand for power batteries continued to grow, resulting in a shortage of cylindrical lithium batteries for IT. With the market adjustment, the current tight supply situation has been gradually eased. The latest lithium battery quotation shows that the price increase of cylindrical lithium battery in the second quarter is about 1~4%. With the expansion of production capacity,

The primary problem of BMS is security, which needs to have: 1) Overcharge protection, that is, the charging needs to be terminated in time when the voltage exceeds the standard. 2) Over-discharge protection, that is, the discharge is terminated when the voltage of any cell in the group is lower than the over-discharge threshold. 3) Over-current and short-circuit protection, the main function is that the output can be automatically turned off and enter the self-locking state when excessive discharge curren

Lithium battery has entered people's daily life on a large scale, but where does it come from? What are the links in the production process of lithium batteries? Although there are some differences in the production process of lithium batteries depending on different lithium battery manufacturers, due to the same principle, the main production processes of lithium batteries are basically the same, generally including: batching, coating, rolling, cutting, slitting , Welding tabs, winding, packaging, baking, liqu

Formation is an important process in the production process of lithium batteries. During chemical formation, a passivation layer is formed on the surface of the negative electrode, that is, a solid electrolyte interface film (SEI film). The quality of the SEI film affects the battery's cycle life, stability, The electrochemical properties such as self-discharge and safety meet the requirements of "maintenance-free" sealing of secondary batteries. However, the SEI films formed by different chemical pro

In the field of consumer electronics, battery capacity and charging speed are eternal topics, and many manufacturers use fast charging technology and battery capacity as gimmicks for their products. At present, lithium batteries are the most used in this field. Lithium batteries were first commercialized in 1991, and later became the standard configuration of electronic equipment. But many people think the technology has reached its limit and want to find alternative sources, so graphene batteries have entered p

There are some differences in the production process of lithium batteries depending on different lithium battery manufacturers, but because of the same principle, the main production processes of lithium batteries are basically the same, generally including: batching, coating, rolling, cutting, slitting, Welding tabs, winding, packaging, baking, liquid injection, formation, forming, volumetric testing and other processes. Lithium battery occupies a place in people's daily life, but where does it come from? W
