Tesla began delivery of the Roadster, an electric sports car, in 2008. With sales of about 2,500 vehicles, it was the first mass production all-electric car to use lithium-ion battery cells. [129] Tesla began delivery of its four-door Model S sedan in 2012. [130] A crossover, the Model X was launched in 2015. [131]
The battery cells used lithium titanate oxide in the anode, providing rapid charge times and extending battery life. It also provided stable discharge from extremely cold (-30 °C) to high temperature above 40 °C. According to Honda, the SCiB battery could charge in about half the time of a typical Li-ion battery.

Hydrogen cations, dissolved in molten lithium chloride, can be discharged on cathodically-polarized graphite rods, which then intercalate, peeling graphene sheets. The graphene nanosheets produced displayed a single-crystalline structure with a lateral size of several hundred nanometers and a high degree of crystallinity and thermal stability.
[106] [107] Examples include LiCl:RH 2 O (a solution of lithium chloride salt and water molecules) in the composition range 4<R<8. [ 108 ] sugar glass , [ 109 ] or Ca 0.4 K 0.6 (NO 3 ) 1.4 . [ 110 ] Glass electrolytes in the form of Ba-doped Li-glass and Ba-doped Na-glass have been proposed as solutions to problems identified with organic ...
Slow motion computer simulation of the black hole binary system GW150914 as seen by a nearby observer, during 0.33 s of its final inspiral, merge, and ringdown.The star field behind the black holes is being heavily distorted and appears to rotate and move, due to extreme gravitational lensing, as spacetime itself is distorted and dragged around by the rotating black holes.
Using Big Bang models, it is possible to calculate the expected concentration of the isotopes helium-4 (4 He), helium-3 (3 He), deuterium (2 H), and lithium-7 (7 Li) in the universe as ratios to the amount of ordinary hydrogen. [38] The relative abundances depend on a single parameter, the ratio of photons to baryons.
DELAG, Deutsche Luftschiffahrts-Aktiengesellschaft I was the world's first airline. [1] It was founded on November 16, 1909, with government assistance, and operated airships manufactured by The Zeppelin Corporation.
