Chemical Overcharge and Overdischarge Protection for Lithium-ion Batteries with LiFePO_4 Positive Electrodes

摘要

1. LiFePO_4/graphite cells can be overcharged without damage if they incorporate a 2,5 ditertbutyl 1,4 dimethoxybenzene shuttle. 2. The shuttle also protects against overdischarge as an added bonus. 3. Deliberately unbalanced series batteries functioned very well. 4. Cells can be overcharged continuously at moderate rates without overheating Watch out Duracell - These will be (indestructible?) cells that one can will to the grandchildren!!!
