How can lithium battery manufacturers break through in materials?

Whether the technological breakthrough of key materials of lithium batteries is important or depends on the use scenario, and then decide how to break through the technical bottleneck based on the use scenario. The four key materials of lithium batteries are negative electrode material, positive electrode material, electrolyte and separator. In the future, lithium battery materials must be the final say by Chinese companies, because my country's lithium battery material suppliers have achieved the transition from imitation-follow-up-catch up, and are currently on the way to catch up and surpass one after another. Both the technology and scale of the cathode materials domestic companies are forming a trend of surpassing, and the future development prospects are promising; in terms of anode materials, domestic companies have the advantages of comprehensive leadership, the industry position has been formed, and it is difficult to be surpassed in a short period of time; Patent and core additives are controlled by foreign companies, and the formula is restricted by the client. Domestic electrolyte manufacturers have actually been reduced to foundries; in terms of diaphragms, domestic companies have made slow technological progress, and the new system has not been broken. To deal with problems, the industry will disrupt the situation. In order to improve the thermal stability of the diaphragm and the wettability of the electrolyte, domestic companies generally apply a layer of ceramic or organic coating on the diaphragm, and even 5 layers at most, although the performance will be improved after the coating , But it also takes up battery space and adds battery weight. In terms of using lithium titanate as a negative electrode material, domestic research has also been fruitful, increasing the specific energy of the battery and reducing the cost. Not only the material has good safety, long life, and high charge-discharge specific power, but it also has the problem of foreign patent protection. In general, the development of lithium batteries in the future requires new alternative materials, reducing the volume, increasing the storage capacity per unit volume, and increasing the charging efficiency per unit time. And reduce costs. In this way, battery technology can be developed.
