How to Improve the Energy Density of the Lithium Battery System?

As a 18650 3.7 v Battery Factory, share with you. Increasing the energy density of a battery system is a systematic project that can start from the development of new materials, optimization of battery structure, and improvement of manufacturing processes.

1. Enhanced lithium battery material

Using different organic chemical management systems, you can change the specific energy. For example, in the cathode material of lithium-ion batteries, the occupancy rate of nickel, cobalt, and manganese is adjusted to increase the occupancy rate of nickel, thereby increasing the specific energy of the lithium-ion battery. In the cathode material of lithium-ion batteries, the volume of silicon/carbon polymer materials can reach 4200mah/g, while the basic theoretical capacity of lithium-ion batteries is only 372mah/g. In addition, many lithium-ion batteries have volume damage during the entire process of charging a battery, and some lithium-ion batteries are damaged during the entire cycle of the entire cycle system. Therefore, the lithium element in the lithium-ion battery or the lithium-ion battery electrolyte is damaged. Filling technology is also the main research content of new batteries.

2. Optimize the layout structure

At present, most battery packs are constructed using various fixing cards and supporting elements in various fixed battery packs. Many structural elements have a large volume and mass, which greatly reduces the high efficiency of overall integration and adjusts the battery pack’s high efficiency. The layout structure simplifies the structure of various installation support points, enabling the lithium-ion battery pack to have a higher volume in a relatively limited room space.

3. Change the specifications of rechargeable batteries

Changing the specifications of rechargeable batteries is also a major aspect of expansion. For example, by changing the length and total width of the rechargeable battery, the lithium-ion battery becomes flatter and narrower in a certain volume, which is beneficial to the overall arrangement of the lithium-ion battery in the battery pack and can increase the space of the power lithium-ion battery Utilization rate, producing a battery pack with greater energy. This kind of graphic design can also make the lithium ion core have a larger total heat extraction area, so that the lithium ion core can immediately transfer the heat generated inside to the outside world, prevent the heat generated by the internal accumulation, and better match the higher Than energy.

4. Application of light materials

In the application of raw materials, in addition to the upgrade of lithium-ion battery materials, the improvement of battery pack materials is also an important measure to increase the ratio of energy to rechargeable battery system software.
