    • A metal-ceramic composite (“cermet”) has been produced by a chemical reaction between a lithium compound and another metal. The cermet has advantageous physical properties, high surface area relative to lithium metal or its alloys, and is easily formed into a desired shape. An example is the formation of a lithium-magnesium nitride cermet by reaction of lithium nitride with magnesium. The reaction results in magnesium nitride grains coated with a layer of lithium. The nitride is inert when used in a battery. It supports the metal in a high surface area form, while stabilizing the electrode with respect to dendrite formation. By using an excess of magnesium metal in the reaction process, a cermet of magnesium nitride is produced, coated with a lithium-magnesium alloy of any desired composition. This alloy inhibits dendrite formation by causing lithium deposited on its surface to diffuse under a chemical potential into the bulk of the alloy.
    • 金属 - 陶瓷复合材料(“金属陶瓷”)已经通过锂化合物与另一种金属之间的化学反应产生。 金属陶瓷具有有利的物理性能,相对于锂金属或其合金的高表面积,并且容易形成为所需形状。 一个例子是通过氮化锂与镁的反应形成一种锂 - 氮化镁金属陶瓷。 该反应导致涂覆有一层锂的氮化镁颗粒。 氮化物在电池中使用时是惰性的。 它以高表面积形式支撑金属,同时稳定电极相对于枝晶形成。 通过在反应过程中使用过量的镁金属,制得氮化镁的金属陶瓷,涂覆有任何所需组成的锂 - 镁合金。 该合金通过使沉积在其表面上的锂在化学势下扩散到合金体中来抑制枝晶形成。
