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 […]

The curious case of ionic liquids: 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 don’t think of high technology, unless you’re really easily impressed by cold-activated cans. However, not everyone knows that […]

Scientists at the DOE’s Oak Ridge National Laboratory have captured the first real-time nanoscale images of lithium dendrite structures in lithium-ion batteries. The ORNL team is confident that its research, published in Nano Letters, will be of great benefit to scientists who are experimenting with different ways to tackle the […]

Researchers at Pacific Northwest National Laboratory (PNNL) have developed a new zinc-polyiodide redox flow battery that could offer more than two times the energy density of existing designs. Flow batteries, which use ionized liquids stored in external tanks in place of traditional electrolytes, have garnered a lot of publicity lately, […]

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 […]

One of the biggest statements on Tesla’s last quarterly conference call was that it would be unveiling a battery storage system for home use within 1–2 months. I know that several competing energy storage companies are watching closely to see what the details (especially price) end up being… while surely also being […]

Liechtenstein-based nanoFlowcell AG has taken a different approach to battery design. Its vehicles use a flow battery system which works like a combination of a battery and a fuel cell, using liquid electrolytes kept in two tanks and pumped through the cell. At the heart of the system is a membrane that […]

Nanostructured electrodes in Li-ion batteries have several advantages, including shorter distances for charge-carrying particles to travel and a high surface area that provides more active sites for electrochemical reactions to occur. However, working with nanoscale materials is tricky – due to their tiny size, they can be hard to control […]

Tesla and Samsung are talking about expanding their battery partnership, industry officials have told the Korea Times. “With Tesla seeking to diversify its battery sourcing channels beyond its key partner Panasonic, Samsung SDI will have greater room to supply more EV batteries to Tesla,” said an unnamed source. Samsung is […]

Renewable energy won’t die from cheap oil. With oil prices hitting six-year lows, you would think cleantech’s momentum would stop. After all, history has not been kind to renewables when oil prices have fallen. However, Bloomberg Business paints a different picture. In his analysis, author Tom Randall cites 7 key reasons […]

The latest advance in lithium-sulfur technology comes courtesy of a research team from Samsung and the University of Rome, who have built a solid-state Li-S battery with a capacity (∼1600 mAhg−1) approaching the theoretical value and Coulombic efficiency approaching 99%. In a paper published in the Journal of The Electrochemical […]
