Latest Patents
Among her latest patents is a cathode that features improved safety mechanisms. This invention includes a cathode active material and poly(amic acid). When the lithium secondary battery, which incorporates this cathode, operates in abnormal conditions of 160°C or higher, a condensation reaction occurs, forming polyimide. This polyimide acts as a protective coating around the cathode active material particles, effectively preventing the transport of lithium ions and electrons. This interruption of current flow inhibits abnormal heat emission, thermal runaway, and combustion caused by additional reactions.
Another notable patent is a battery cell capable of measuring its inner temperature. This invention includes an electrode assembly structured with a cathode, an anode, and a separator. The surfaces of the electrode current collectors are coated with an electrode mixture that includes an active material. The design features external input/output terminals and a resistance measurement terminal, allowing for precise monitoring of the electrode current collector's resistance.
