The document summarizes nickel-cadmium (NiCd) batteries, which were invented in 1899 and use nickel and cadmium electrodes. NiCd batteries are rechargeable and were commonly used in portable electronics and power tools due to their durability and consistent performance. They consist of a cadmium anode, nickel oxide cathode, and potassium hydroxide electrolyte. While NiCd batteries are lighter and have longer life than lead batteries, they also contain the toxic metal cadmium and are heavier than other rechargeable batteries. Common applications included calculators, cameras, and cordless power tools.

3. Introduction
RELIABLE RECHARGEABLE BATTERIES
WITH NICKEL AND CADMIUM ELECTRODES
DEAL FOR PORTABLE ELECTRONICS AND
POWER TOOLS DUE TO THEIR DURABILITY
AND CONSISTENT PERFORMANCE.

4.  The founder of NiCd cell is
Waldemar Jungner, a Swedish
inventor and engineer who
created the first NiCd battery
in 1899. He experimented with
different combinations of
nickel, cadmium, and iron as
electrodes and electrolytes.
