Chemistry of Battery Cells Used in Rav4 EV??

[reeler]

I heard that the Model S uses Panasonic cells with nickel-cobalt-aluminum cathodes. But, I also heard that the 80KW model uses different cells from the 60KW and 40KW versions.

Does anyone know which cells were actually used in the Rav$?

2200mAh Panasonic 18650.

It's pretty much public knowledge what battery Tesla uses throughout the EV community. One note, however; the Tesla Model S and X with 40kWh and 60kWh batteries are different than the 85kWh battery with Panasonic NNP 3.4Ah cell. This is the new Lithium Nickel Cobalt Aluminum Oxide cathode material with a carbon anode.

"One key to the Model S's design is the use of a flat lithium-ion battery pack that sits at the base of the vehicle. At NAIAS, the company displayed the flat battery pack, which contains at least 7,000 small 18650-type batteries, each measuring 18mm in diameter by about 65mm long (slightly larger than a AA battery). The Model S's battery packs come in three capacities -- 40kWh, 60kWh, and 85kWh -- with successively higher numbers of the 18650-type batteries in each. Tesla said that the flat battery pack contrasts with other lithium-ion EV packs on the market today in that it takes up almost no space in the cabin of the vehicle."

"Panasonic Corporation and Tesla Motors announced on October 11, 2011 (JST) that they have finalized a supply agreement for automotive-grade lithium-ion battery cells. Panasonic is the world's leading battery cell manufacturer and a diverse supplier to the global automotive industry. Panasonic's automotive grade lithium-ion battery cells will be used in Tesla's premium electric sedan, Model S."

Hi Reeler, consensus is leaning toward it using Panasonic's NCR18650A cell (3.6V/3.1Ah), which uses NCA (nickel-cobalt-aluminum) cathode with graphite anode chemistry.
