Default Toyota is launching the next generation Hybrid Battery !

The upcoming big Hybrid sedan from Toyota's Lexus line, will implement the : Nickel Metal ho2? ( Hydrogen ) ? Battery !

Toyota claims more energy density per given mass than the current battery compound and system technology used in the Hybrid lines, of_Toyota/Lexus !

More on this as soon as I can decipher the murky posting from Toyota Japan's upcoming technology to be used in the now, present / future of Toyota and Lexus Hybrid vehicles.

for present and next generations to come.

That sounds like Nickel Metal Hydride, the very battery chemistry already being used Toyota's HSD systems. However, they could have improved the configuration, just as they improved the configuration from Gen1 to Gen2. However, reports I have seen indicates Toyota is looking to go LiIon. There are safe ones out now.

Got it DanMan, However, why will Toyota deploy the same Nimet battery to the new upcoming Lexus LS600h if and when they already have the
Lithium battery comin' up ? I read something like Nickel Metal-Hydrogen !
I have to get into this as soon as possible. Will post at once when know more.

Yes, please get us a link if you find anything. Usually innovative battery chemistries are revealed before their practical application, such as a new Lexus, is revealed. It would be pretty strange for a major car company to put an unknown battery chemistry into a production vehicle.

I think they just mean nickel-metal-hydride (NiMH), the same type as already used.

However as Danman said, Panasonic (who supply all of Toyota's hybrid batteries) have been improving the NiMH they supply every 3-4 years.

The NiMH from Prius 1 - HSD was a particular jump in power density, for example. This is presumably further development of the same line.

Because they don't. According to Dave Hermance they don't have a lithium battery and won't for some time. But when it finally does come, it will replace current batteries and be the direction things will go.

Default New Battery Chemical compound ? Nh-ion

Ok, deciphered Toyota posting. It says: Nickel Hydrogen-Ion battery
that carries so much punch that can propel the heavy and upcoming : All new: Lexus LS 600h from standing start to 0~60, 0~100 mph in a few seconds !

comparable to any High Tech v12 ICE ( Elapsed time not released as of yet ) Also claims an extraordinary FE and torque + power unheard of in any existing or upcomin' Luxury sedans of the world.

No links available at this time. This new model is not released yet so still under the mistique vail ? Will be watching this upcomin' Wunder_battery to such claims.

So where is the _LiIon, that we all talk about as to Toyota bringing out in the next gen Hybrids.

Not too many hits on Nh-ion battery.
Got a few hits on Hydrogen Ion, where various metals can be used as one of the electrodes, including nickel. I belive Lithium is the more common one, if the ion is hydrogen.
The problem with Nickel is that the reserves are depleting, thus Nickel is going up in price.

Maybe there will be a coin drive to collect the precious metal.

Yes, it's more than doubled in price since the original Prius!

It's one reason why they want to switch to LiIon in the next model Prius (lithium is far more abundant).

Nickle Metal Hydride batteries have inside a metal alloy that absorbs hydrogen, forming a "Metal Hydride", so you might say hydrogen is involved - but there should not be any free hydrogen! There have been some minor improvements in NiMH batteries, however, it looks like the future is with lithium batteries.

Lithium is much more abundant and cheaper than nickel, and lithium batteries store 80 to 140 wh per kg, vs. 60 wh/kg for NiMH. Production costs and safety have been the main barriers to automotive use of lithium, but there have been major improvements in safety, and production is improving driving down costs.

Lithium Sulfur batteries, almost ready for market, store approx. 340 wh/kg. Experimental lithium air cells have exceeded 1,000 wh/kg and may reach 3,000 wh/kg!

I drove Prius before Prius was cool!
