0.1: 12.5 × 1.6 Used in some lighted watches and some LED decorator lights (electronic tea candles). CR1220: 5012LC: 35–40: 0.1 (CR) 0.03 (BR) 12.5 × 2.0 Used in keychain LED flashlights, and in some digital cameras to keep the time and date function running even when the main battery is taken out of the camera.

The nominal voltage of a fresh alkaline cell as established by manufacturer standards is 1.5 V. The actual zero-load voltage of a new alkaline battery ranges from 1.50 to 1.65 V, depending on the purity of the manganese dioxide used and the contents of zinc oxide in the electrolyte. The voltage delivered to a load decreases as the current drawn ...
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.
An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections [1] for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode. [2]
A lithium-titanate battery is a modified lithium-ion battery that uses lithium-titanate nanocrystals, instead of carbon, on the surface of its anode.This gives the anode a surface area of about 100 square meters per gram, compared with 3 square meters per gram for carbon, allowing electrons to enter and leave the anode quickly.
Lithium salt or a salt such as a tetraalkylammonium chloride dissolved in LiClO 4 in an organic solvent that is a mixture of 1,2-dimethoxy ethane, 1,3-dioxolane and 2,5-dimethyloxazole as a stabilizer [28] 1.5 V Li–PbCuS Lead sulfide and copper sulfide: 1.5 V 2.2 V Li–FeS Iron sulfide: Propylene carbonate, dioxolane, dimethoxyethane: 1.5 ...
The first generation rechargeable alkaline batteries were introduced by Union Carbide and Mallory in the early 1970s. [3] [5] Several patents were introduced after Union Carbide's product discontinuation and eventually, in 1986, Battery Technologies Inc of Canada was founded to commercially develop a 2nd generation product based on those patents, under the trademark "RAM".
2 MnO 2 + ZnCl 2 + H 2 O + 2 e − → Mn 2 O 3 + Zn(OH) 2 + 2 Cl −. giving the overall reaction Zn + 2 MnO 2 + H 2 O → Mn 2 O 3 + Zn(OH) 2. The battery has an electromotive force (emf.) of about 1.5V. The approximate nature of the emf is related to the complexity of the cathode reaction. The anode (zinc) reaction is comparatively simple ...
