【PR】システム構築、ソフトウェア開発はイーステムにお任せ下さい


Right after inventing nickel-cadmium in 1899, Sweden’s Waldemar Jungner experimented with to be able to substitute metal with regard to cadmium in order to save cash; even so, weak impose productivity along with external battery for iphone motivated them to be able to forego the actual improvement without getting the obvious.

The particular nickel-iron battery (NiFe) uses the oxide-hydroxide cathode along with the metal anode together with potassium hydroxide electrolyte along with makes the nominal cell voltage of 1. 2V. NiFe will be strong to be able to overcharge along with over-discharge and will past with regard to a lot more than 2 decades in standby apps. Level of resistance to be able to vibrations along with high temperature ranges built NiFe preferred battery with regard to mining in European union, along with through World Battle II the actual battery run the actual The german language V-1 flying an explosive device and the V-2 rockets. Various other apps are railway signaling, forklifts, along with strength with regard to stationery apps. external battery for iphone features a small unique energy of approximately 50Wh/kg, provides weak low-temperature effectiveness along with reveals high self-discharge of 20 to be able to 50 percent every thirty days. This particular, together with high producing cost, motivated the industry to be faithful to be able to direct acid.
