The iPad Air marked the first major design change for the iPad since the iPad 2; it has a thinner design that is 7.5 millimeters thick and has a smaller screen bezel similar to the iPad Mini. Apple reduced the overall volume for the iPad Air by using thinner components resulting in a 22% reduction in weight over the iPad 2. [14]

Open circuit voltage = 1.6 V; Working voltage = 1.2~1.5 V; Energy density = 130 Wh/kg (60 Wh/lb) [2] Service life of several thousand hours (continuous operation) [9] Shelf stable over several years (retaining 90% of initial capacity) [10] Silver oxide cells are a primary battery and do not have a cycle life or a rate of charging and ...
The color is greyish, white, or yellow. The bond between the carbon and fluorine atoms is covalent, thus fluorine is not intercalated. [clarification needed] Such materials have been considered as a cathode in various lithium batteries. Diagram of intercalation of Li into a titanium disulfide cathode.
In organic synthesis, LiI is useful for cleaving C-O bonds. For example, it can be used to convert methyl esters to carboxylic acids: [9] RCO 2 CH 3 + LiI → RCO 2 Li + CH 3 I. Similar reactions apply to epoxides and aziridines. Lithium iodide was used as a radiocontrast agent for CT scans. Its use was discontinued due to renal toxicity.

Mercury battery "РЦ-53М"(RTs-53M), Russian manufactured in 1989. A mercury battery (also called mercuric oxide battery, mercury cell, button cell, or Ruben-Mallory [1]) is a non-rechargeable electrochemical battery, a primary cell. Mercury batteries use a reaction between mercuric oxide and zinc electrodes in an alkaline electrolyte.
An AA-sized alkaline battery might have an effective capacity of 3000 mAh at low drain, but at a load of 1 ampere, which is common for digital cameras, the capacity could be as little as 700 mAh. [12] The voltage of the battery declines steadily during use, so the total usable capacity depends on the cutoff voltage of the application.
