The technical development of lithium battery separators is advancing with the application of lithium ion batteries. The outstanding features are the smaller and smaller the lithium batteries and the longer the development trend of lithium batteries.
China's lithium battery industry is in the ascendant. Under the encouragement of national policies, the existing capacity expansion and potential capacity development have doubled year by year. As the most profitable separator in the inner layer components of lithium-ion batteries, it is the first to develop.
The main performance requirements of current lithium battery separators are: thickness uniformity, mechanical properties (including tensile strength and puncture strength), gas permeability, physical and chemical properties (including wettability, chemical stability, thermal stability, safety), etc. Four major performance indicators.
The technical development of lithium battery separators is advancing with the application of lithium ion batteries. The outstanding features are the smaller and smaller the lithium batteries and the longer the development trend of lithium batteries.
Seen from the "small"
Mainly embodied in lithium batteries for portable consumer electronics, such as mobile phones, digital cameras, electronic dictionaries, etc., the high energy density requirements for the design of lithium batteries in terms of aesthetics and miniaturization, the diaphragms for such lithium battery applications should be made thinner and thinner. Because the meaning of high energy density is to accommodate more electrode materials in a small volume, under the condition that the positive and negative materials have been determined, the performance of the diaphragm is inevitable, which requires the original diaphragm to be thinner. Some battery capacity and cycle life.
Seen from the "big"
Mainly reflected in the lithium-ion battery used in electric bicycles and electric vehicles. It is not difficult to see through the domestic self-ignition of electric vehicles. Safety performance is currently the bottleneck restricting power lithium batteries. The main reasons for this are in these three areas:
1. Safety is the core of the physical and chemical properties of the lithium ion battery separator. Any one of the other three properties may cause the safety performance to be unstable.
2. The larger the capacity of the power lithium battery cell itself, the smaller the number of cells required to be connected in series. This objectively requires the power lithium battery to use a larger capacity battery. The larger the capacity, the more the battery core Performance indicators require more elaborate processes to ensure;
3, due to the consistency of the series of cells and the combination of technology will bring security risks, which in particular requires the manufacture of lithium battery separators more sophisticated.
The excellent performance of lithium batteries and lithium battery packs cannot be fully expected in a piece of diaphragm, the full matching of the positive and negative electrodes and the electrolyte components can achieve this goal, and the lithium battery pack has more combined technical problems. However, the importance of diaphragm technology as the most valuable lithium battery technology is self-evident.
