Ni Mh

Hi,

rogerg:


Just a question. Now that AB seems to be going back to ni-cad due to the uncertanty of lithium has the use of ni-nmh been considered. In model use they do the similar job to ni-cd but are lighter and smaller and seem to be pretty safe.

The strategy of EADS seems very good. Aviation uses Ni Cad (successfully)
Probably Ni mh was not NOW considered for the IMO GOOD move from EADS. Certainly was studied prior decision to use Li ion.

AFAIK Ni Mh is not being used in airliners. In the mean time (A350) could still adopt Li ion. If possible.

I think may happen in the future. A battery redesign is not so complex.

A BAD design "burned" the name Li ion. It has merits.
