  2. Jelly roll (battery) - Wikipedia

    en.wikipedia.org/wiki/Jelly_roll_(battery)

    The jelly roll or Swiss roll design is the design used in the majority of cylindrical rechargeable batteries, including nickel–cadmium (Ni-Cd), nickel-metal hydride (Ni-MH), and lithium-ion (Li-ion). The design has this name because the cross section of the battery looks like a Swiss roll.

    This allows these tools to produce as much torque as some corded drills. Common battery types of are nickel-cadmium (NiCd) batteries and lithium-ion batteries, with each holding about half the market share. NiCd batteries have been around longer, so they are less expensive (their main advantage), but have more disadvantages compared to lithium ...

    Nickel–iron battery, a type of rechargeable battery using nickel(III) oxide-hydroxide positive plates and iron negative plates, with an electrolyte of potassium hydroxide; Nickel–metal hydride battery, a type of rechargeable battery with the negative electrodes use a hydrogen-absorbing alloy instead of cadmium

  5. Nickel–lithium battery - Wikipedia

    en.wikipedia.org/wiki/Nickel–lithium_battery

    The battery is predicted to hold more than twice as much energy per kilogram as lithium-ion batteries, and to be safer. However, the battery will be complex to manufacture and durability issues have yet to be resolved. [1] Ni–Li has a very high cell potential, but is limited in capacity by the cathode material.

  6. Lithium-ion battery - Wikipedia

    en.wikipedia.org/wiki/Lithium-ion_battery

    A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life.

    In lead-acid batteries, this is known as sulfation, but deep-discharge damage also affects other types such as nickel-cadmium batteries and lithium batteries. [25] Therefore, it is commonly recommended that rundown tests be performed infrequently, such as every six months to a year. [26] [27]
