High energy density rechargeable cell for medical device applications |
摘要 |
A re-balanced lithium ion secondary cell, particularly one comprising LiCoO2 cathode active material, is described. The preferred anode material is carbonaceous, and the couple is balanced to a ratio of the cathode active material to the anode material of from about 1.35 to about 2.25. This significantly improves the energy density of the secondary cell over that known by the prior art by increasing the charge voltage to at least 4.4V.
