Thermal Battery Could Heat and Cool a Vehicle Without Using Electricity

EV heating and cooling presents a dilemma: how to keep a vehicleâ€™s occupants comfortable without draining the battery? Engineers are working on various solutions, from heat pumps and adsorption chillers to passenger-focused AC and heat. A group of researchers from the University of Utah, HRL Laboratories and GM Global R&D […]

Tesla Courting Japanese Battery Suppliers For Possible 2nd Gigafactory

With the development process of the first gigafactory apparently going quite smoothly, Tesla Motors is apparently already busy courting Japanese battery suppliers with regard to a potential second gigafactory. This possible second gigafactory would of course be located outside of North America, and seems quite sensible in many ways. Considering […]

Stanford Team Improves Potential of Solid-State Electrolytes by Enhancing Ionic Conductivity

Solid-state electrolytesâ€™ potential advantages in energy density and safety compared with conventional liquid electrolytes have made them the hottest topic in the battery world. However, there are several challenges to be overcome, including the low mobility of lithium ions in solid electrolytes. Now, a team of Stanford researchers have used […]

Your EV Battery Lifespan Might Last Longer Than You Think

A fresh look at actual driving records has yielded a surprising (to some) conclusion about the useful lifespan of electric vehicle (EV) batteries. Conventional wisdom has it that EV drivers will ditch their ride after the battery loses 20% of its storage capacity, but our friends over at Lawrence Berkeley […]

EV Battery Costs Already â€˜Probablyâ€™ Cheaper Than 2020 Projections

The cost of electric vehicle battery packs is falling so rapidly they are probably already cheaper than expected for 2020, according to a new study in Nature Climate Change. Electric vehicles remain more expensive than combustion-engine equivalents, largely because of battery costs. In 2013 the International Energy Agency (IEA)Â estimatedÂ cost-parity could […]

Researchers Discover New High-Performance Cathode Material for Lithium-Sulfur Batteries

Lithium-sulfur batteries are one of the hottest topics in the battery field today, as they could theoretically offer energy density up to four times higher than that of lithium-ion batteries. However, one of several challenges to be overcome is finding cathode materials that demonstrate long-term stability. An international team of […]

Ionic Liquid Electrolytes May Open the Door for Higher-Voltage Batteries

The curious case of ionic liquids:Â Boulder Ionics/CoorsTek Specialty Chemicals Iolyte electrolytes When you think of liquids under the brand name Coors, you think of the Silver Bullet, the Banquet Beer. You certainly donâ€™t think of high technology, unless youâ€™re really easily impressed by cold-activated cans. However, not everyone knows that […]

Nickel-metal Hydride: the Battery Tech of the Future?

Conventional wisdom has it that lithium-ion batteries are the state of the art, and that nickel-metal hydride chemistry, which is used in most conventional hybrids (some of the newer Prius models now use Li-ion), is pretty much obsolete. However, scientists at BASF believe that NiMH technology still has much to […]
