2. Rapala - Wikipedia

   en.wikipedia.org/wiki/Rapala

   Rapala (/ ˈ r æ p ə l ɑː / RAP-ə-lah) [1] is a fishing product manufacturing company based in Finland. It was founded in 1936 by Lauri Rapala, who is credited for creating the world's first floating minnow lure carved from cork with a shoemaker's knife, covered with chocolate candy bar wrappers and melted photography film negatives, for a protective outer coating.

3. 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.

4. Lithium nickel manganese cobalt oxides - Wikipedia

   en.wikipedia.org/wiki/Lithium_nickel_manganese...

   Lithium nickel manganese cobalt oxides (abbreviated NMC, Li-NMC, LNMC, or NCM) are mixed metal oxides of lithium, nickel, manganese and cobalt with the general formula LiNi x Mn y Co 1-x-y O 2. These materials are commonly used in lithium-ion batteries for mobile devices and electric vehicles , acting as the positively charged cathode .

5. Battery charger - Wikipedia

   en.wikipedia.org/wiki/Battery_charger

   A battery charger, recharger, or simply charger, [1][2] is a device that stores energy in an electric battery by running current through it. The charging protocol—how much voltage, current, for how long and what to do when charging is complete—depends on the size and type of the battery being charged. Some battery types have high tolerance ...

6. Lithium metal battery - Wikipedia

   en.wikipedia.org/wiki/Lithium_metal_battery

   The term "lithium battery" refers to a family of different lithium-metal chemistries, comprising many types of cathodes and electrolytes but all with metallic lithium as the anode. The battery requires from 0.15 to 0.3 kg (5 to 10 oz) of lithium per kWh. As designed these primary systems use a charged cathode, that being an electro-active ...

7. Lithium ion manganese oxide battery - Wikipedia

   en.wikipedia.org/wiki/Lithium_ion_manganese...

   One of the main research efforts in the field of lithium-manganese oxide electrodes for lithium-ion batteries involves developing composite electrodes using structurally integrated layered Li 2 MnO 3, layered LiMnO 2, and spinel LiMn 2 O 4, with a chemical formula of x Li 2 MnO 3 • y Li 1+a Mn 2-a O 4 • z LiMnO 2, where x+y+z=1. The ...
