Power bank battery dismantled and reviewed

Image
Power bank battery dismantled and reviewed (backup battery for iPho ne produced in China) Before we start some explanation and disclaimer . Here is a short review, based on observations and simple calculation of one of "power bank" or backup battery for iPhone , which may be found in any shop. I did not intend to do this review simply because I did not buy that device and not going to buy such things in a future (ne ar future ). This example device I have got from my frie nd after its stoped working and actu ally the pla s tic shel l become opened (Fig. 2) . This is not a denunciation or exposure for certain product or certain manufacturer or certain country. I hope t his review will make you more skeptical and realistic about what you see and what you get. All dismantle and photos, as well calculation and conclusions done by me.   Although I dismantle Li -ion batteries (LIB) of any shape and size many times for many years since I have work with it for the l...

new iPad`s (3?) battery capacity upgrade

According to DigiTimes Apple may increase battery capacity of upcoming high-end version of new iPad The battery capacity for the high-end version of Apple's new iPad - due to be unveiled in January 2012 - will be increased to 14,000mAH compared to 6,500mAH used currently, according to industry sources. Apple's battery suppliers Simplo Technology and Dynapack declined to comment on matters concerning clients. {Apple is set to unveil two versions of its next-generation tablet, one for the high-end segment and one for the mid-range segment, the sources said.}? Meanwhile, the penetration rate of lithium-polymer batteries such as those used in iPad 2 is expected to reach 15% in 2012 compared to 5% in 2011, the sources estimated. Global production of lithium-polymer battery cells will top 400 million units in 2011, and the prices of the cells are expected to remain higher in 2012 after being hiked by 20% in the second quarter of 2011, the sources indicat...

Porous SnO2/layered titanate nanohybrid with enhanced electrochemical performance for reversible lithium storage : Chem. Commun. , 2012, Advance Article DOI : 10.1039/C1CC14769B, Communication Joo-Hee Kang, Seung-Min Paek, Jin-Ho Choy Porous heterostructure of SnO 2 -layered titanate nanohybrid has been synthesized via an exfoliation/reassembling process. This hybridization gives rise to a remarkable enhancement of discharge capacity with a good capacity retention.
