Lithium and Nickel Metal Hydride
Lithium and Nickel Metal Hydride
(OP)
I have an application for a rechargeable battery. My question is, which is the better technology--the rechargeable Lithium or the Nickel Metal Hydride? Is one or the other preferable for rechargeability? for current density? for discharge voltage characteristics?
Thanks
Thanks





RE: Lithium and Nickel Metal Hydride
With regard to charging and cycle life, NiMH can generally be charged faster and will have longer cycle life than Li-Ion. State of the art charging technology can charge NiMH in about one hour to 80% of capacity and there is technology in development to charge in as little as 15 minutes. Improvements in Li-Ion charging technology have made charging in one hour possible commercially.
