USE OF ULTRA-FINE CARBON COLLOID FOR IMPROVING VARIOUS BATTERIES, LEAD-ACID, LI-ION, NI-MH AND ALKALINE MnO_2 BATTERIES

摘要

Recently we reported that colloidal graphite of 0.8mm in average is useful to extend cycle life of lead-acid batteries (1). Now we found 0.15mm organic-carbon colloid are very stable and useful in various batteries for improving the Ah capacity and cycle life. With this ultra fine carbon, the active materials of Li-Ion and Ni-MH batteries and Alkaline MnO_2 cells will be coated to produce a thin conductive layer, and improve the material packings in these cells.
