Hyundai is complementing its standard 10-year, 100,000-mile warranty by adding a "lifetime battery replacement guarantee" for the Sonata Hybrid, the only hybrid the South Korean automaker sells.

Hyundai has unveiled the BlueOn, which it claims is South Korea's first full-speed battery electric vehicle (EV). The tiny BlueOn is based on the Hyundai's i10 minicar and was first shown as a prototype at last year's Frankfurt Motor Show when it was called the i10 Electric. The little EV is equipped with a 16.4 kWh lithium-polymer battery pack but other than the capacity, Hyundai hasn't announced details about the battery yet. The pack will probably come from LG Chem, which also supplies lithiu

Could it be that Tata is expecting to move lots of Indica Vista EVs when they bring them to the market, beginning with Norway later this year? If the tea leaves are being read properly, then yes. A short press release from the American offices of the South Korean battery maker Energy Innovation Group Ltd. (EIG) announces that they will supply their lithium polymer cells to Miljøbil Grenland AS, the Indian giant's Norwegian subsidiary until 2012. The agreement anticipates as many as two mi

While lead acid batteries have energized electric cars for most of the motoring age and nickel metal hydrides (NiMH) have helped hybrids return high gas mileage numbers more recently, the future seems to securely belong to lithium batteries for both applications. With all that's riding on this technology, can it really fulfill its green promises? Of the dozens of electric vehicle announcements have been made over the past few years, practically all of them have named lithium ion batteries as the

Battery-powered cars have a lot to recommend them, but they still have one major flaw - the batteries! Compared to almost any other energy storage solution, even the best of today's electrochemical batteries still have very low energy density and very high cost. Every major car manufacturer is pursuing electrically-driven vehicles with lithium ion batteries as a solution to the problem of CO2 emissions and oil consumption. They all are aware of the fact that virtually all of these cars will be m

We've been keeping pretty close tabs on the Hyundai Avante / Elantra LPI mild electric hybrid. Just when we thought there couldn't possibly any new details to add about the propane burner, out pops a press release from the Korean manufacturer announcing that the LG Chem-supplied battery underpinning the hybrid component of the car will actually be lithium polymer (li-poly) as opposed to the lithium ion type that had been previously publicized. Now you may be thinking to yourself, understandably,

By now we've all heard about "thermal incidents" with various type of lithium batteries and we've probably even seen videos of exploding laptops. Many of you have also complained about why it's taking so long for car-makers to get lithium batteries to market. One of the main causes of batteries getting too hot is overcharging or charging too fast.

Solar power has the highest power density among all renewable energies, so we should certainly be devoting a great deal of research into how best to capture and use that power. Being that solar electric power cells generally deliver their power in the form of DC current, as opposed to AC current like would be used in a home, it makes sense to pair solar power with batteries and battery powered devices. One problem with this strategy is that electronics tend to be small, and get smaller with each

Lithium-ion batteries have been in use for some time in our personal electronics devices, most notably in laptop computers. The switch was made to lithium-ion from NiMh, or nickel metal hydride batteries because they are lighter, cheaper, and smaller than other kinds of batteries. They don't suffer from the 'memory' effect that gave nickel batteries a bad name, they contain relatively few toxic metals and are fairly simple to recycle. Nickel metal hydride and ni-cad or nickel cadmium batteries w

Fashion industry stars André and Coqueline Courrèges have produced a third fully-functional EV prototype, the Zooop, a lightweight car that can go 450 km (about 280 miles) per charge and uses "Lithium Polymer batteries that are lighter, have greater power density don't overheat, charge quicker and offer many more recharges" and can reach speeds of 180 km/h (about 112 mph), according to Gizmag.
