Abstract: Lithium ion batteries with improved fire resistance properties are described. The lithium ion battery includes a first electrode including a lithium compound and a second electrode. A separator is positioned between the first electrode and the second electrode and an electrolyte is provided. wherein the separator comprises at least a layer of polymeric nanofibers positioned on one side of a separator core and a fire-retardant polymer coating formed opposite to the nanofiber layer which is simultaneously deposited during electrospinning process. The polymeric nanofibers have a diameter less than approximately 1 micron. The polymeric nanofibers have a fire-retardant material entrapped within the nanofibers. The fire-retardant material has a lower melting point than the polymeric nanofibers. The separator/nanofibers/fire-retardant material are configured such that a fire-initiating event releases the entrapped fire-retardant material from the nanofibers which extinguishes the fire-initiating event.

Abstract: The present invention describes a method of producing a p-type light-absorbing semiconductor copper zinc tin selenide/sulfide (Cu2(ZnxSn2-x)(SySe1-y)4) (abbreviated CZTS) with electrochemical deposition. It can be used in the production of solar cell when combined with an n-type inorganic or an organic semiconductor layer. The present method comprises a one-step or a sequence of depositions using electroplating to fabricate a low-cost and large-area CZTS solar cell, without using expensive and complicated deposition techniques or highly toxic and flammable chemicals in the production process. The present method significantly reduces the cost and energy requirement for production of solar cell.
