Lithium-ion Technology

摘要

In 2005, milwaukee electric tool corp. introduced the first lithium-ion powered cordless tools for professionals, and a good case can be made that the proliferation of lithium-ion tools that has followed is the most significant tool development in recent years. To many tool users' surprise, Milwaukee unveiled a line of 28V lithium-ion tools. They provide more power and weigh less than standard 18V tools. Their lithium-ion battery packs last twice as long per charge as nickel-cadmium (NiCd) batteries and sustain maximum power through each charge without the gradual decrease in power typical of NiCd batteries.
