The technology of inverted battery cells and positive cells of new energy vehicles is becoming the focus of people's attention. These two technologies play an important role in the battery system of new energy vehicles, and their advantages and disadvantages and application scenarios have aroused extensive discussions.
First of all, let's take a look at the battery cell inversion technology. As the name suggests, cell inversion is to place the battery cell upside down so that the positive and negative poles of the battery cell are opposite to the positive and negative poles of the battery pack. The advantage of this technology is that it can make full use of the space of the battery pack and increase the energy density of the battery. In addition, the inverted battery cell technology can also reduce the thickness of the battery pack, so that the center of gravity of the vehicle is lowered, and the stability and handling of the vehicle can be improved. The "battery cell inversion" technology announced by Xiaomi Auto may become the mainstream in the future, and innovative exploration is worthy of recognition in any era and any field. Xiaomi's industry-leading battery cell inversion technology can quickly release energy downward under extreme conditions, ensuring the safety of the passenger compartment to the greatest extent.
In contrast, the upright battery cell technology places the battery cells upwards in a conventional way, with the positive and negative electrodes in line with the positive and negative electrodes of the battery pack. The advantage of this technology is that the structure of the battery cell is more stable, and it is not prone to safety problems such as short circuits. Or take the mainstream automobile manufacturer General Motors Buick E5 as an example, it still adopts the form of battery cell upright on the Autoneng electric vehicle platform, places the cell pressure relief port in a place that is relatively not easy to be impacted, and arranges a large area of 2 aerogel fire blankets between the battery cell and the cockpit; This is not over, in order to deal with the flames that spread along the direction of the air flow when the first occurs, the battery pack is also equipped with a pressure relief valve and a fast exhaust channel to quickly discharge high-temperature gases and avoid deflagration or ** caused by concentrated heat release to the greatest extent.
In general, the inverted battery cell technology and the upright battery cell technology have their own advantages, and we need to choose the appropriate technical solution according to the actual needs. At the same time, we are also looking forward to more technological innovations and breakthroughs to inject new vitality into the development of new energy vehicles. Let us work together for the cause of environmental protection and create a better future!
