§ Mr. Wakefield
asked the Parliamentary Secretary to the Admiralty whether he will consider the use in submarines of iron-nickel accumulators instead of lead, thus obviating chlorine hazard when sea-water comes into contact with lead-type accumulators?
§ Mr. Shakespeare
The possibility of using iron-nickel accumulators in submarines has frequently been considered, and accumulators of this type have been fully tested. These tests showed that this type of accumulator has serious disadvantages which makes it less suitable for use in submarines than the batteries which are at present used. The problem of providing the most satisfactory type of battery for use in submarines is constantly under investigation.
