Electric cars may have an advantage over gasoline cars in energy density when powertrain efficiency is considered.

Since the start of Tesla Model S electric-car production in 2012, the company's lithium-ion cells have been supplied by its Japanese partner Panasonic. That applies to the more recent Tesla Model X crossover SUV as well—and Panasonic was also an early investor in Tesla Motors shares, owning a...

Energy storage has never been the subject of more research, capital investment, and business interest than it's experiencing in this decade. With lithium-ion cells at the forefront of both electric cars and stationary batteries used to store renewable energy for later use, batteries are hot. Now...

Graphite battery anodes are made using a toxic substance.

Lithium-ion cells and the battery packs that hold them are the single most costly part of modern electric cars. And how fast their costs will fall remains the defining factor in making those cars affordable for the mass market. GM made waves last fall when product chief Mark Reuss said the company...

University of California, Irvine, researchers believe a nanowire-based battery cell could last much longer than current cells.

Only Nissan and Tesla currently offer electric cars with different battery-pack options.

In theory, it's a wonderful concept: once their tenure in an electric car is over, lithium-ion battery packs with as much as 70 percent of their energy capacity remaining can be sold and reused. In practice, however—especially at scale—the idea turns out to have some practical...

Last night's Tesla Model 3 electric car unveiling is getting all the attention today, with at least 135,000 reservations booked for the car. But to get the $35,000 Model 3 out the door with the announced 215-mile range, a generation of lithium-ion cells will be required for its battery. And that's...

Local media looks inside the Tesla "Gigafactory."

Either Bosch or Panasonic could reportedly supply battery cells for Porsche's electric sedan.

The Federal government's Advanced Research Projects Agency-Energy said last week that it has made huge strides toward creating a next generation of batteries for energy storage. The agency is tasked with kickstarting energy-related projects in the private sector; its director suggested that the new...
