A group of researchers led by Professor Marcin Molenda from the Jagiellonian University in Krakow has developed three very important improvements to traditional Li-Ion batteries. The first is CAG, a technology for the production of anodes based on carbogel produced from starch (sic!) extracted from rice, potatoes or corn. Starch is subjected to gelatinization using water (green chemistry process) and then subjected to the process of pyrolysis with combustion of the emitted gases. This method allows you to completely eliminate graphite from the anode without losing battery performance and leaves a zero carbon footprint (at anode level). The durability of such an anode is more than 1500 cycles.
Another technology is LKMNO, a technology for the production of high-voltage cathodes for cobalt-free Li-Ion batteries, with five times lower nickel content and twice lower lithium content (compared to NMC materials). The production of such a cathode is also based on "green chemistry" and leaves practically no carbon footprint. The cost of production is twice as low and lithium is used fully effectively. In classic batteries, lithium is used only in 50%.
The third technology is CCL (Carbon Conductive Layer), a thin carbon coating protects the battery against self-ignition. It is the process of coating active materials (cathode and/or anodic) with a thin layer of carbon with a thickness of several nanometers. By choosing the right coating thickness, you can adjust such battery parameters as discharge time or load limit. As a result, additional carbon materials no longer need to be used in the battery, and as a result, the energy density increases. But the most important thing is that such a coating eliminates the danger of spontaneous combustion practically to zero, because the carbon layer tightly covers all active materials. CCL is also produced in a green chemistry process, no gases are formed in the process and prototype tests showed a service life of 3000 cycles.
All processes are protected by patent law and are at the stage of acquiring partners to implement in production.
