  • Patent number: 11021367
    Abstract: Provided is a porous lithium composite phosphate-based compound containing lithium and having open pores formed in primary particles. As the open pores are formed in the primary particles themselves, a contact area between an electrolyte and the lithium composite phosphate-based compound is maximized, and low conductivity is compensated for, such that a diffusion rate of lithium ions is remarkably increased, and when the lithium composite phosphate-based compound is used as an active material of a secondary battery, the secondary battery may be charged and discharged at a high speed. Additionally, there are advantages in that an electrode density may be significantly increased in addition to the increase in the diffusion rate of the lithium ions, and charge and discharge cycle characteristics may be significantly stable.

  • Patent number: 10573930
    Abstract: The present invention relates to an electrolyte containing a polydopamine and a lithium-sulfur battery including the same and, more particularly, to a technique in which polydopamine contained in an electrolyte adsorbs a lithium polysulfide eluted from a positive electrode of a lithium-sulfur battery. When using an electrolyte, according to the present invention, to which polydopamine particles are added, the polydopamine particles dispersed in the electrolyte act to adsorb lithium polysulfide eluted from a positive electrode during the charging and discharging, and thus can suppress the diffusion thereof, i.e., suppress a shuttle reaction, thereby improving the capacity and lifetime characteristics of the lithium-sulfur battery.
