At present, the energy density of lithium battery is low. First of all, the energy density is low, the car is heavy, and the space is small. You need to find new battery materials. Secondly, the battery life has poor battery life, claiming that the battery life reaches more than 100 kilometers or more refers to the ideal state. The actual pavement battery life is about 60 kilometers. If there are big congested cities such as Beijing, 60 kilometers are not enough. The third is poor security. This problem is still controversial, because the materials for battery are unstable, and it is indeed easy to explode.
The lithium battery negative electrode material grasps the safety of the power battery. In the lithium -ion battery negative material, in addition to graphic middle phase carbon micro -ball (MCMB), non -fixed carbon, silicon or tin category occupy an extra market, natural graphite and artificial artificial artificial Graphite occupies more than 90%of the market share of negative materials.
In summary, the development direction of the positive electrode material of lithium -ion battery is lithium iron phosphate. Although the research and development of lithium iron phosphate positive materials in China is in full swing, it lacks original innovation technology. There are two development directions for lithium -ion batteries in the future -lithium titanate materials and silicon -based materials. The silicon -based materials developed in China in recent years can basically meet the requirements of high ratio, high power characteristics, and long cyclic life. my country has achieved certain results in the localization of lithium -ion battery diaphragm, but there is still a long way to go to achieve large -scale production of high -end products. Lithium hexifluoropensphosate occupies an absolute market advantage in electrolytes in lithium -ion batteries, but my country is basically subject to Japanese technology and has a weak independent research and development strength.
Conductor coating in battery materials
The surface treatment of the battery conductive substrate using the function coating is a breakthrough technological innovation. Carbon -covered aluminum foil/copper foil is to cover the scattered nanotomicic graphite and carbon. Copper foil. It can provide excellent static conductive performance, collect the micro -current of the active substance, so that it can greatly reduce the contact resistance between positive/negative pole materials and set flow, and can improve the attachment ability between the two, reduce bonding, can reduce bonding The amount of doses increases the overall performance of the battery to significantly improve.
The coating water division (water system) and oil (organic solvent system).
The performance advantage of conductive coating carbon aluminum foil/copper foil
1. Significantly improve the consistency of battery packs and greatly reduce the cost of battery pack.
(1) significantly reduce the increase in the internal resistance of the battery cell.
(2) Improve the voltage difference between the battery pack.
(3) Extend the life of the battery pack and greatly reduce the cost of battery packs.
2. Improve the adhesion of the active materials and the streaming body, and reduce the cost of manufacturing.
(1) Improve the adhesion of the positive electrode materials and collectives of the water -based system;
(2) Improve the adhesion of nano -level or sub -micron -level positive electrode materials and collective electrodes;
(3) Improve the adhesion of lithium titanate or other high -capacity negative electrode materials and collector;
(4) Improve the qualification rate of the polar sheet and reduce the cost of polar film manufacturing.
3. Reduce polarization, increase magnification and gram capacity, and improve battery performance.
(1) Partially reduces the proportion of adhesives in active materials and increase grams of capacity;
(2) Improve electricity contact between active substances and streams;
(3) Reduce polarization and improve power performance.
