How to improve the energy density of 3.7v 18650 lithium battery systems
How to improve the energy density of 3.7v 18650 lithium battery systems? Improving the energy density of 3.7v 18650 lithium battery systems is a systematic project, which can start from the development and design of new materials, the improvement of rechargeable battery structures, and the improvement of production and manufacturing processes.
1. Upgraded battery core materials use different chemical systems, which can change the energy density. For example, by adjusting the proportions of nickel, cobalt, and manganese in the main battery cathode materials to increase the proportions of nickel, cobalt, and manganese. The silicon/carbon polymer material on the negative electrode material reaches 4200Mah/g, while the basic theoretical volume of the negative electrode material in lithium batteries is only 371mah/g, which is much lower than the silicon/carbon polymer material. In addition, many lithium-ion batteries have capacity loss during the first charging process, and some lithium ions may also be lost during the cycle. Therefore, the technology of supplementing lithium elements into electrodes or electrolytes is also a major research direction in current battery technology.
2. The most common 3.7v 18650 lithium battery pack on the market is a small module + various fixings and supports in the battery pack. Many components occupy a large amount of volume and quality, which greatly reduces the overall integration efficiency. Adjusting the packaging structure and simplifying the installation support structure can make the main components more compact and increase the volume of 3.7v 18650 lithium battery components in a limited space. The CTP (3.7v 18650 lithium battery module) plan released by the battery brand this year has changed the structure of the original core component-3.7v 18650 lithium battery module. The 3.7v 18650 lithium battery module is composed of several large-capacity lithium batteries, and the 3.7v 18650 lithium battery pack is stacked with large components. Compared with traditional 3.7v 18650 lithium battery packs, this solution not only reduces the number of parts, but also reduces space and specific energy usage. Therefore, simplifying the structure of 3.7v 18650 lithium battery packs and forming a two-level integrated design of 3.7v 18650 lithium battery packs has become a technical direction that many companies tend to choose.
3. Change the specifications of the 3.7v 18650 lithium battery pack Changing the specifications of the 3.7v 18650 lithium battery pack is also an important aspect of expansion. For example, by changing the length and width of the 3.7v 18650 lithium battery pack, the center becomes flatter and narrower, which is beneficial to the spatial layout of the 3.7v 18650 lithium battery pack, improves the space efficiency of the 3.7v 18650 lithium battery pack, and increases the specific energy of the 3.7v 18650 lithium battery pack. The advertising design can also make the key have a large heat dissipation area, so that the key can directly transfer internal heat to the outside, avoid the accumulation of internal heat, and thus achieve higher specific energy as quickly as possible.
4. Use lightweight materials in material applications. In addition to the upgrade of battery materials, the improvement of battery packaging products is also an important way to increase the specific energy of battery systems. The use of lightweight materials has become key. At present, battery box materials usually use aluminum alloy materials, high-strength steel plate materials and polymer materials. The density of aluminum alloy is low, only about one-third of that of stainless steel. Using aluminum alloy profiles instead of stainless steel can significantly reduce the weight of 3.7v 18650 lithium battery components. The surface of aluminum alloy profiles will form a high-density and stable oxide film, which can resist corrosion. , High-quality battery box materials. The strength of high-strength steel can be very high, and the high-toughness battery shell can be lighter, lower in cost, and has good plasticity. It is an ideal battery pack box material and is currently widely used in battery packs. .
