1. The current problem of lithium ion battery

    The current lithium -ion battery, the current problem is: the problem of poor fast charging performance, the problem of poor charging and discharge performance at low temperatures, and low communication energy density, including poor stability. The solution of these problems needs to be mentioned below. Materials start.

Second, lithium -ion battery positive and negative terminal materials

     The problems mentioned above are listed with electrolytes. The lithium ion batteries we now use mainly use liquid electrolytes, but according to prediction, the next generation of lithium batteries should be a all -solid lithium battery. " If we can overcome the problem of all -solid lithium batteries in the industry, and then do lithium sulfur and lithium -empty batteries, related technical problems will be solved.

    In response to the problem of rapid and low -temperature charging lithium -ion batteries mentioned above, we can start with the following points, including

1. Negative materials-improve the lithium-ion diffusion coefficient;

2. Electrolytic fluid-improve the low temperature activity of lithium ions;

3. Battery preparation process-shorten lithium ion transmission channels;

4. Conductors-increase electronic conductivity and ion conductivity.
