Abstract

The invention comprises thermal batteries employing an FeS/sub 2/ depolarizer itself. A minor amount of CaSi/sub 2/ preferably 1-3% by weight is provided as an additive in the FeS/sub 2/ depolarizer to eliminate the voltage transient (spike) which normally occurs upon activation of batteries of this type. The amount of FeS/sub 2/ by weight generally comprises 64 to 90%.

Cathode additives for lithium-ion batteries

Patent Cui, Yi; Sun, Yongming

In some implementations, a cathode is formed by (1) providing a cathode additive including (a) a matrix including a lithium compound, and (b) metal nanostructures embedded in the matrix; and (2) combining the cathode additive with a cathode active material to form a mixture. In other implementations, a cathode is formed by (1) providing a cathode additive including a compound of lithium and at least one non-metal or metalloid; and (2) combining the cathode additive with a cathode active material to form a mixture.
