CARBON ADDITIVES FOR SILICON-CONTAINING ELECTRODES - A simplified explanation of the abstract
This abstract first appeared for US patent application 17824601 titled 'CARBON ADDITIVES FOR SILICON-CONTAINING ELECTRODES
Simplified Explanation
The abstract describes an electrode for an electrochemical cell that cycles lithium ions.
- The electrode contains a silicon-containing electroactive material, three different types of carbon additives, and specific weight percentages of each component.
- The first carbon additive has an aspect ratio between 1 and 3, the second carbon additive has an aspect ratio between 3 and 500, and the third carbon additive has an aspect ratio between 20 and 10,000.
- The electrode consists of 80-97% silicon-containing electroactive material, 0.5-15% of the first carbon additive, 0.1-15% of the second carbon additive, and 0.01-5% of the third carbon additive.
Original Abstract Submitted
The present disclosure provides an electrode for an electrochemical cell that cycles lithium ions. The electrode includes a silicon-containing electroactive material, a first carbon additive having a first aspect ratio greater than or equal to about 1 to less than or equal to about 3, a second carbon additive having a second aspect ratio greater than or equal to about 3 to less than or equal to about 500, and a third carbon additive having a third aspect ratio greater than or equal to about 20 to less than or equal to about 10,000. The electrode includes between about 80 wt. % and about 97 wt. % of the silicon-containing electroactive material, between about 0.5 wt. % and about 15 wt. % of the first carbon additive, between about 0.1 wt. % and about 15 wt. % of the second carbon additive, and between about 0.01 wt. % and about 5 wt. % of the third carbon additive.
