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 […]

Volkswagen Set To Make Decision On Solid-State Technology From QuantumScape

The Volkswagen Group’s decision on what exactly to do with the solid-state energy storage technology currently under development by the company QuantumScape will be made sometime before July, according to a recent report from Bloomberg. That report — which cited the Chairman of the Board of Management, Professor Martin Winterkorn […]

EV Battery Costs Already ‘Probably’ 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) estimated 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: 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 […]

Real-time Images of Lithium Dendrite Structures Could Lead to Better Batteries

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 Develop Redox Flow Battery With High Energy Density

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, […]

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 […]

Tesla Home Battery On The Way

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 […]

QUANTiNO Concept With Low-Voltage Flow Battery Has 620-mile Range, 124 mph Top Speed

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 […]

Snail Shells Inspire New Battery Design

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 […]
