  • Carbogel anode materials and method for their preperation
    Patent number: 11117802
    Abstract: Carbogel anode materials and method for their preparation are disclosed. The described carbogels exhibit, at a temperature of 20° C., an electrical conductance of at least 0.5 S/cm and a reversible electrochemical capacity in relation to lithium of at least 350 mAh/g under a C/2 discharge current, enabling their use for preparation of anode materials, particularly those intended for preparation of lithium-ion cells.
    Type: Grant
    Filed: February 3, 2017
    Date of Patent: September 14, 2021
    Assignee: UNIWERSYTET JAGIELLONSKI
    Inventors: Monika Bakierska, Marcin Molenda, Agnieszka Chojnacka, Michal Swietoslawski
  • LKMNO cathode materials and method of production thereof
    Patent number: 10978707
    Abstract: LKMNO cathode materials based on a lithium-manganese spinel modified synergetically with potassium and nickel, and a method of production thereof are disclosed. The LKMNO cathode materials are characterised by a reversible gravimetric capacity in relation to lithium of at least 250 mAh/g after 80 operation cycles under a current load of 1 C, so that they are suitable for application in lithium-ion batteries with a high energy density.

  • Process for the preparation of conductive carbon layers on powdered supports
    Patent number: 8846135
    Abstract: A process for the preparation of carbon layers on powdered supports comprising dissolving a hydrophilic polymer (PH) at the level of 85 do 99.9% by weight in water, adding pyromellitic acid (PMA) or pyromellitic dianhydride (PMDA) at the level of 0.1-15% by weight, then introducing to the mixture the powdered support at a level of 1-99% by weight. The suspension is concentrated and dried, and the composite precursor formed is subjected to a pyrolysis process at 300-1500° C.
