2. Spot welding - Wikipedia

   en.wikipedia.org/wiki/Spot_welding

   Spot welding is also used in the orthodontist's clinic, where small-scale spot welding equipment is used when resizing metal "molar bands" used in orthodontics. Another application is spot welding straps to nickel–cadmium, nickel–metal hydride or Lithium-ion battery cells to make batteries. The cells are joined by spot welding thin nickel ...

3. Electric resistance welding - Wikipedia

   en.wikipedia.org/wiki/Electric_resistance_welding

   Spot welding is a resistance welding method used to join two or more overlapping metal sheets, studs, projections, electrical wiring hangers, some heat exchanger fins, and some tubing. Usually power sources and welding equipment are sized to the specific thickness and material being welded together.

4. 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.

5. Thin-film lithium-ion battery - Wikipedia

   en.wikipedia.org/wiki/Thin-film_lithium-ion_battery

   Thin-film lithium-ion batteries can be used to make thinner portable electronics, because the thickness of the battery required to operate the device can be reduced greatly. These batteries have the ability to be an integral part of implantable medical devices, such as defibrillators and neural stimulators, “smart” cards, [ 8 ] radio ...

6. Shot welding - Wikipedia

   en.wikipedia.org/wiki/Shot_welding

   Shot welding is a type of electric resistance welding which, like spot welding, is used to join two pieces of metal together. The distinguishing feature is that in shot welding, strips and sheets of metal (usually stainless steel) are "sewed" together with rows of uniform spot welds. [ 1 ]
