Hi Graham,
Lithium Ion cells also fail to a short.
But, typical consumer LiIon "batteries" include a safety protection circuit that will disconnect the cell from the battery terminals if the cell voltage drops below the min discharge voltage so it looks like it fails open.
For example: http://datasheet.sii-ic.com/en/battery_protection/S8200A_E.pdf

Hi All,
It is "said that" NiCad battery cells usually fail to "short circuit" and that Lithium Ion ones usually fail by just loosing their ability to hold a charge viz they go "open circuit"
Is this true or....?
many thanks
