Abstract: A conductive material includes a conductivity performance index PC ranging from 0.03 to 8.10. The conductivity performance index is defined by an aspect ratio, a powder resistance, a packing density when the powder resistance is measured, BET specific surface area, and volume cumulative average particle diameter D50. Such a conductive material is capable of improving the performance of an electrode by utilizing physical properties which may be related to resistance characteristics and lifespan characteristics of the electrode, such as the conductive material forming a conductive network connection path between active material particles and within an active material particle in the electrode, being arranged in pores, and being arranged on the surface of an active material.

Abstract: A positive electrode including a positive electrode composite layer disposed on a current collector, the positive electrode composite layer including a positive electrode active material, carbon nanotubes, and carbon black. A ratio, (BETCB)/(BETCNT), of a BET surface area BETCB of the carbon black to a BET surface area BETCNT of the carbon nanotubes is between 1.0 and 3.4, and the carbon nanotubes have a number cumulative average particle size D50CNT ranging from 0.9 ?m to 4.0 ?m. A positional relationship between the carbon nanotubes and the carbon black within the positive electrode and connectivity with active material particles are excellent, and thus both ionic conductivity and electrical conductivity are improved. Accordingly, a lithium secondary battery offering superior resistance, improved lifespan, and price competitiveness is provided.

Abstract: Embodiments of the described technologies receive, via a user interface, an input associated with a first user of a user connection network. The input identifies first position data related to a position capable of being filled by a hiring of a person. In response to validating the first position data, second position data different from the first position data is extracted from the user connection network, based on the first position data. A first prompt is formulated based on the first position data and the second position data. The first prompt is sent to a generative language model. A first piece of writing is received from the generative language model. The first piece of writing includes a position description output by the generative language model based on the first prompt. The position description is sent to the user interface in response to the input.

Abstract: A positive electrode having a mixture layer includes a single particle-type positive electrode active material and a point-type conductive material, disposed on a current collector. The positive electrode having the mixture layer also includes a rolling index ranging from 0.01 to 1.00. The rolling index is determined using a single particle formation degree of a single particle-type lithium nickel-based oxide, a bulk density, a BET specific surface area, and an oil absorption number of a point-type conductive material. The positive electrode exhibits a low porosity and a high rolling density. Also provided is a lithium secondary battery including the same having excellent energy density.
