Abstract
The present invention provides an anode including a host material capable of absorbing or desorbing lithium in an electrochemical system. A stabilized lithium metal powder coated with a wax is dispersed in the host material.
Claims
exact text as granted — not AI-modified1 . An anode comprising a host material capable of absorbing or desorbing lithium in an electrochemical system wherein, a stabilized lithium metal powder coated with a wax is dispersed in the host material.
2 . The anode of claim 1 , wherein said host material comprises at least one material selected from the group consisting of carbonaceous materials, silicon, tin, tin oxides, composite tin alloys, transition metal oxides, lithium metal nitrides, graphite, carbon black, and lithium metal oxides.
3 . The anode of claim 1 , wherein the wax has a thickness of 20 μm to 200 μm.
4 . The anode of claim 1 , wherein the stabilized lithium metal powder further comprises an inorganic coating.
5 . The anode of claim 4 , wherein the inorganic coating is selected from the group consisting of Li 2 CO 3 , LiF, Li 3 PO 4 , SiO 2 , Li 4 SiO 4 , LiAlO 2 , Li 2 TiO 3 , and LiNbO 3 .Join the waitlist — get patent alerts
