RE: [Electric Boats] lower priced lithium cells on the horizon

My latest lithium cost me 21.7c/kwh as part of a 23kwh purchase that included 2 BMS boards on each 48V 3kwh module plus cables contactor etc. Surplus options these days are looking good for electric boating. I wouldn't hold my breath waiting for 10c per WH. Oil companies have time to stop that from becoming reality.

Subject: [Electric Boats] lower priced lithium cells on the horizon

Just read about this manufacturing breakthrough that purports to cut in
half the cost of producing lithiun ion cells.
From what I understood, it allows the electrolyte layers to be thicker
and manufactured in a continuous roll and avoid drying times. I
especially like the $0.10/wh projection by the year 2020. At that cost,
lithium will be the best thing going by any metric for electricity
storage in boats.

My existing 5kwh pack cost just about $2500, including BMS and battery
packaging (straps, buss bars, etc). Others here have also said under
$0.50/wh is achievable. To bring the cell cost down to the $0.15-$0.20
at low-volume retail level would be just absolutely amazing. On a
per-usable-ah level, that is on par with wet-lead in price even
including a basic BMS, but still has all the volume and weight
advantages of lithium.
