Abstract

Described here is a powder comprising a plurality of lithium-containing particles having a dry, uniform protective layer, wherein the protective layer of the particles is obtained by a sequential vapor phase reaction or adsorption process. Also described is a battery comprising an anode layer and a cathode layer, wherein the cathode layer comprises lithium metal oxide or a lithium metal phosphate, wherein the metal comprises at least one of Nickel, Manganese, Cobalt, Iron, Titanium, and/or Manganese, wherein the cathode particles have a dry, uniform protective layer, and wherein the anode layer comprises lithium titanium oxide particles.

Claims

exact text as granted — not AI-modified
1 - 22 . (canceled) 
     
     
         23 . A powder comprising a plurality of lithium-containing particles having a diameter of 60 μm or less; a uniform alumina protective layer disposed over the lithium-containing particles. 
     
     
         24 . A battery comprising an electrode wherein the electrode comprises the lithium-containing particles of  claim 23 . 
     
     
         25 . The powder of  claim 23  wherein the lithium-containing particles having a diameter in the range of 10 nm to 500 nm. 
     
     
         25 . The powder of  claim 23  wherein the lithium-containing particles having a diameter in the range of 10 nm to 100 nm. 
     
     
         26 . The powder of  claim 23  wherein the lithium-containing particles comprise LiMn 2 O 4 , LiCoO 2  or LiNiO 2 . 
     
     
         27 . The powder of  claim 23  wherein the lithium-containing particles comprise LiFePO 4 . 
     
     
         28 . The powder of  claim 23  wherein the lithium-containing particles comprise LiTiOi 2 . 
     
     
         29 . The powder of  claim 23  wherein the lithium-containing particles comprise LiMn 2 O 4 , and further comprising Mg or Ni. 
     
     
         30 . The battery of  claim 24  comprising particles of LiFe x Ti y Mn 2-x-y O 4  where 0<y<0.3.
