Abstract: Phosphors based on doping of an activator (an emitter) into a host matrix are disclosed herein. Such phosphors include alkaline gallate phosphors doped with Cr3+ or Ni2+ ions, which in some embodiments can exhibit persistent infrared phosphorescence for as long as 200 hours. Such phosphors can be used, for example, as components of a luminescent paint.

Abstract: The invention relates to a lithium-ion battery cell, which comprises an electrode component, a metal can for accommodating the electrode component, electrolyte injected into the metal can, and a cap plate affixed to the metal can, wherein the electrode component comprises a cathode film, an anode film and separator; a cathode tab is arranged on the positive plate; an anode tab is arranged on the negative plate; the cap plate is provided with a positive terminal electrically connected with the cathode tab, a negative terminal electrically connected with the anode tab, a liquid injection hole and an explosion-proof vent; safety components are assembled between the metal can and the electrode component and electrically connected with the positive terminal or the negative terminal; and the metal can is electrically connected with the negative terminal or the positive terminal.
