lithium 3400mah 3.7v 18650 battery

　　Daimler joins forces with three institutions to develop new lithium 3400mah 3.7v 18650 battery

　　Recently, overseas media reported that Daimler has joined forces with ThyssenKrupp Systems Engineering, Germany's IAV and Fraunhofer Institute for Ceramic Technology and Systems to develop bipolar batteries based on lithium-ion technology. project. If this technology is successfully developed, it may increase the cruising range of pure electric vehicles to 1,000km.

　　Recently, overseas media reported that Daimler has joined forces with ThyssenKrupp lithium-ion battery manufacturer Bo System Engineering, Germany's IAV company and Fraunhofer Institute for Ceramic Technology and Systems to develop lithium-ion technology-based products. Bipolar battery research and development project. If this technology is successfully developed, it may increase the cruising range of pure electric vehicles to 1,000km.

　　The name of the new battery research and development project is EMBATT-goes-FAB. The project will develop a new lithium-ion battery product called a bipolar battery based on the current mainstream lithium-ion battery technology, and plans to use it in new energy vehicles in the future. superior. The new battery has the characteristics of high energy density. If used in pure electric vehicles, it is expected to increase the vehicle's endurance to 1,000km.

　　Bipolar batteries are similar to fuel cells, consisting of stacked electrodes connected in series, except that the electrodes are bipolar, that is, the active materials of the positive and negative electrodes of the battery are applied to a common electrode carrier. It's like having two different sauces on the same pancake.

　　In addition, the packaging process of this kind of battery lithium-ion battery is different from the current common lithium-ion battery. There is no battery cell state. Instead, all the pancakes are stacked in a certain space. After the stacking is completed, all the pancakes are loaded into one Fixed casing. This packaging method is just like printing paper after packaging, neat and space-saving. During the packaging process, some shell components and connecting elements are reduced compared with the current mainstream lithium-ion battery packaging process, which can effectively save costs and space, thereby making room for more active materials, allowing the battery to store more energy. In order to achieve the purpose of improving the endurance of pure electric vehicles.
