nickel-metal-hydride battery

  • 2018 Toyota Prius

    Toyota continues to stay the course with nickel-metal hydride battery cells for many of its hybrid vehicles, even though most other hybrid vehicles from other brands have moved on to using lithium-ion cells exclusively. According to Prius chief engineer Shoichi Kaneko, in an interview this past week at the LA Auto Show, most of Toyota’s current hybrid lineup are capable of easily trading off between the two battery types for one chief reason: flexibility. In being compatible with either one, the company can more smoothly react at a factory or vehicle level to supply shortages or price...

    Nickel-Metal-Hydride Batteries For Electric Cars? Energy Density Can Rise 10-Fold: Researchers

    The division is pretty clear: nickel-metal-hydride batteries are for use only in hybrids--at least those from Toyota, which has used more of the batteries than any other maker by far. Lithium-ion cells, on the other hands, are the only ones with sufficient energy density to be used in the much...

    With plug-in cars now on the market, rare-earth metals are a hot commodity.

    Replacing A 2001 Toyota Prius Battery Pack: What It Cost

    It's one of the most frequent questions asked about hybrids: What happens if I have to replace the high-voltage battery pack? While Toyota warrants its Prius batteries for 8 years/100,000 miles (or 10 years/150,000 miles in some states), cars more than a decade old won't be covered--and may still...

    Will Old Electric-Car Battery Packs Cause Horrible Pollution?

    It's an assertion that comes up a lot in comments on our stories. It goes, essentially, like this: No one recognizes the horrible pollution problems that will arrive when hybrid and electric cars are junked, and their nickel-metal-hydride and lithium-ion battery packs go into landfills. It's a...

  • Lithium-ion battery pack of 2011 Nissan Leaf, showing cells assembled into modules

    A common misconception of electric cars and hybrid vehicles is that at the end of a short battery life, the remainder is dumped in landfill and contributes ever more pollution to the Earth. Of course, we know this to be incorrect. Not only are the more common lead acid batteries the world's most recycled product, but dumping old ones makes little economic sense either. Not only that, but battery life in hybrid cars is already well-proven under the toughest of conditions - as yellow cabs in New York and San Francisco. Electric car batteries use expensive metals like nickel and cobalt in their...

    Do you remember the shoe sized cell phones of the early 90s? Much of that size was due to the battery. Even with that large battery, you were lucky to get 30 minutes of talk time. Battery tech has made slow and steady progress since then and has been doing so for the last 40 years. There were advancements before then too, but this modern era of advancement kicked off when NASA needed batteries for the Lunar Rovers of the Apollo Project. More recently batteries have become the powerhouse for all of our high tech gadgets. This has spurred innovation investment to a level that battery tech has...
