A NEW WET BATTERY

The invention, reported from Europe, of a new type of accumulator battery, differing in important respects from existing types of storage batteries, is likely to have an important influence on wireless reception, and to prove'a serious rival to the new "all electric" wireless receivers which operate directly from domestic electric supply mains. The chief features of the new storage battery are that it is less bulky, and much lighter than lead, or iron and nickel type of batteries, anid that its capacity, or the amount of eurrent it will store up, on each. charge, greatly exceeds that of ordinary storage batteries. Although electrically the lead accumulator and the iron and nickel accumulator have been made very efficient, the need for charging them at fairly frequent intervals, and the difficulty in handling them, due to their size and weight, have been undoubted disadvantages. It is claimed that one of the new accumulators, not so heavy as a standard form of lead battery, has a capacity nearly ten times greaten than that of a lead battery. It follows from this that such a lead battery would run ten times as long as a lead battery for each charge, or alternatively, that a battery operating on the new principle made ‘to have the same capacity as ordinary lead batteries, would be so small and light that it could be carried about in the pocket.
