As you know Toyota have been planning a next-generation Hybrid Prius, but there have been many delays. The main reason for these delays is all to do with the li-ion batteries, Toyota were not happy with this and decided to scrap the lithium ion batteries in their Prius cars.
However news has now come to light that Toyota has asked for permission so that they may test a prototype of a plug-in Prius on the roads of Japan, and guess what? The Prius is said to have li-ion batteries.
It seems that Toyota cannot make their mind up.

Lithium is much more expensive than Nickel, and is not proven to work in EVs. Lead and Nickel are the battery that works, the standard EV battery.
Lithium does not satisfy the three requirements for an EV:
1. POWER to start without help from an IC engine;
2. DEEP CYCLE enough for 25 kWh (about 2/3 of a gallon of gas, enough for 100 miles);
3. LONG CYCLE LIFE, at least 1,000, preferrably 2,000, so that the battery lasts at least 100,000 or 200,000 miles.
Why ignore working NiMH, which works every day for our 120-mile range Toyota RAV4-EV, maximum speed 80 mph, 5-passenger, all-electric, Nickel battery plug-in EV??
