The ninth-generation iPad was discontinued on May 7, 2024, with the announcement of the iPad Air (6th generation) and the iPad Pro (7th generation). It was the last iPad model to have a home button, Lightning port and headphone jack. [5] The iPad 9th generation was later replaced with the 10th generation in October 2022.
The iPad Air was available with 16, 32, 64 or 128 GB [a] of internal flash memory, with no expansion option. Apple also sells a "camera connection kit" with an SD card reader, but it can only be used to transfer photos and videos. [20] As of the announcement of the iPad Pro 9.7-Inch on March 21, 2016, the iPad Air was discontinued.

The fifth generation of iPad Air was announced on March 8, 2022, and released on March 18. It used an Apple M1 chip. The sixth generation of iPad Air was announced on May 7, 2024, with the general availability on May 15, 2024. It used an Apple M2 chip. It is the first iPad Air to have the available two display size options including 11-inch and ...
Anode-free lithium ion batteries have been demonstrated using a variety of cathode materials, such as LiFePO 4, LiCoO 2, and LiNi 1/3 Mn 1/3 Co 1/3 (NMC 111).. These intercalation-type cathodes typically offer limited Li content (14.3 at.% for LiFePO4, 25 at.% for LiCoO2 and LiNixCoyMn1-x-yO2), although they remain the primary research targets. [2]
CR2032 lithium button cell battery Lithium 9 volt, AA, and AAA sizes. The top object is a battery of three lithium-manganese dioxide cells; the bottom two are lithium-iron disulfide cells and are compatible with 1.5-volt alkaline cells. Lithium metal batteries are primary batteries that have metallic lithium as an anode.
They are available in small sizes as button cells, where the amount of silver used is minimal and not a prohibitively expensive contributor to the overall product cost. Silver oxide primary batteries account for 30% of all primary battery sales in Japan (64 mil. out of 212 million in February 2020).
Twelve-volt LiFePO 4 batteries are also gaining popularity as a second (house) battery for a caravan, motor-home or boat. [ 50 ] Tesla Motors uses LFP batteries in all standard-range Models 3 and Y made after October 2021 [ 51 ] except for standard-range vehicles made with 4680 cells starting in 2022, which use an NMC chemistry.
