The structures also include shells that encapsulate these porous base structures. During lithiation of the active material, the shell mechanically constrains the porous base structure. The shell allows lithium ions to pass through but prevents electrolyte solvents from interacting with the encapsulated active material. In certain embodiments, the shell contains carbon, while the porous base structure contains silicon. Although silicon tends to swell during lithiation, the porosity of the base structure and/or void spaces inside the shell helps to accommodate this additional volume within the shell without breaking it or substantially increasing the overall size of the composite structure. This allows integration of the composite structures into various types of battery electrodes and cycling high capacity active materials without damaging the electrodes' internal structures and deteriorating cycling characteristics of batteries. | 03-03-2016 |
| 20160067473 | METHODS FOR FORMING AN ELECTRODE DEVICE WITH REDUCED IMPEDANCE - Improved low-cost, highly reliable methods for increasing the electrochemical surface area of neural electrodes are described.

Another technique is to deposit addition metallization material into the interstitial space. The result is undulation surface features provided on the exposed surface of the metallization. This helps improve the electrochemical surface area when the treated metallizations are fabricated into electrodes. | 03-10-2016 |
