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.

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.
The iPad Air's successor, the iPad Air 2, was announced on October 16, 2014, and released on October 22, 2014, however, the 64 GB and 128 GB variants were discontinued, and later the 16 GB and 32 GB on March 21, 2016, after the announcement of the 9.7-inch iPad Pro.

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]
The performance of this nanowire as anode for lead-acid battery has also been evaluated. Due to largely increased surface area, this cell was able to deliver an almost constant capacity of about 190 mAh g −1 even after 1,000 cycles. [14] [15] This result showed this nanostructured PbO 2 as a fairly promising substitute for the normal lead ...
Diagram of a battery with a polymer separator. A separator is a permeable membrane placed between a battery's anode and cathode.The main function of a separator is to keep the two electrodes apart to prevent electrical short circuits while also allowing the transport of ionic charge carriers that are needed to close the circuit during the passage of current in an electrochemical cell.
