Titanium Dioxide to improve Lithium Batteries, page-4

Great point @Propunter2 . You post about DoD recently has made me research all emerging battery and storage techs with this specific data in mind.

Food for thought when you see @Propunter2 's chart above of the lithium batteries DoD.

There are many advantages to Imergy’s flow battery, but one of the most important features is its ability to be discharged to 100% depth of discharge (DoD). “Most people make the mistake of comparing – for example – a 5kWh lead-acid battery bank against a 5kWh Vanadium system,” says Covertel business manager Mario Cacchione.

“A 5kWh lead-acid battery cannot be fully discharged to 5kWh without killing it in a few hundred cycles. Furthermore, it cannot be run with rapid charging and it must be kept cool. The recharge time is also long, and life cycle is limited to about 1500 cycles even with a limit of 50% DoD. Imergy’s vanadium redox flow battery, on the other hand, can be cycled to 100% DoD without impairing its ability to hold a charge.

quickedit: Not meaning to take anything away from your post @noodly , as it's great that more uses for vanadium are being uncovered. Plus it can't hurt that vanadium is thrown around with the darling lithium! Just furthering on from what propunter2 was meaning with his DoD table. GLTAH!
