Researchers at the University of Leicester [have] found a way to use ultrasonic waves to separate out valuable materials from electrodes so that the materials can be fully recovered from batteries at the end of their life.
Current recycling methods for lithium-ion battery recycling typically feed end-of-life batteries into a shredder or high-temperature reactor ... The disassembly of lithium-ion batteries has been shown to recover a high yield (around 80 per cent of the original material) in a purer state than was possible using shredded material ... The team´s ultrasonic delamination technique effectively blasts the active materials required from the electrodes leaving virgin aluminium or copper. The process proved highly effective in removing graphite and lithium nickel manganese cobalt oxides, commonly known as NMC.

The net is a series of tubes (Stevens, 2006) through which cats carry information in packets (Butterworth, 2011). The failure modes have been less well studied. Several exist, but to date the most researched are fracture, disjunc- tion, and joule-based disruption. FRACTURE causes complete regional internet failure. It occurs when construction or other human activity severs or collapses an underground tunnel through which the cats travel. The symptom of DISJUNCTION is high lat- ency; the usual cause is hooligans placing containers of tuna or cream at tunnel junctions. Data corruption results from JOULE- BASED DISRUPTION, caused by the static charge that accumulates as long-haired cats speed through the tunnels. This shocks the cats, who drop their packets. -- Lolapin (2020) = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = _______________________________________________ Address messages to [email protected] No other addresses in TO and CC fields UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub ARCHIVE: http://www.evdl.org/archive/ LIST INFO: http://lists.evdl.org/listinfo.cgi/ev-evdl.org
