Show New battery has longer life span A new battery that improves with age and has a life span twice that of other batteries has been developed by Bell Telephone Tel-ephone Laboratories to protect telephone service. Jack Dalton, district manager for Mountain Bell, said the new cylindrical 1 e a d-acid battery will be used for emergency power. The Bell System currently cur-rently maintains more than a million storage batteries in telephone tel-ephone buildings throughout the nation for emergencies, he said. Bel) Laboratories, the research re-search and development arm of the Bell System, anticipates the new battery's life span at more than 30 years. The battery features circular grids made of pure lead. The pure lead corrodes more slowly than commonly used lead alloys. al-loys. The battery's energy-producing material is a crystalline paste designed to interlock for added strength. Normal corrosion has been harnessed to work as an advantage. ad-vantage. The corrosion in the new battery increases the fcmount of energizing paste, leading to an increase in the total capacity with age. Eventually, Even-tually, of course, the battery will fail. In its present form, according accord-ing to Dalton, the battery sn't intended for automobiles, but the principles involved could ultimately ul-timately be applied to cars. |
