Better and cheaper batteries will be one of the key enabling technologies for the clean, distributed energy system of the future. More specifically, they are a critical component of Tesla’s master plan to produce an affordable mass-market EV. The Seers of Silicon Valley added a big name to their stable […]

It is the very nature of a battery that, over time, the capacity to store electricity begins to degrade. After an electric vehicle battery has lost about 30% of its total capacity, it’s generally deemed unfit for continued use in a car and is replaced. But those batteries aren’t just […]

As the air in some Chinese cities approaches the consistency of egg-drop soup, the country’s government is pushing electrified vehicles and renewable energy in a big way, and this is driving huge growth in the energy storage market, which will be worth $8.7 billion in 2025, more than four times […]

Tesla may have made it trendy, but the California company is far from the only automaker exploring the commercial energy storage market, which is expected to grow from $200 million in 2012 to $19 billion in 2017, according to research firm IHS CERA. Nissan has joined forces with Green Charge […]

PowerGenix, a supplier of automotive nickel-zinc (NiZn) batteries, has completed a product evaluation test plan with the Institute of Automotive Technologies Dresden (IAD). IAD evaluated the capabilities of NiZn batteries used as a 12 V auxiliary power unit for plug-in vehicles, or as a 12 V starter battery for stop-start […]

Still looking for a replacement for lithium? How about magnesium? It’s divalent, so it can displace double the charge per ion (i.e., Mg2+ rather than Li+). It’s much more abundant than lithium, and more stable. However, researchers investigating Mg-ion batteries have run into several limitations, including anode/electrolyte incompatibility. Now a […]

Estonian/German ultracapacitor maker Skeleton Technologies has raised Series B financing of €9.8 million ($10.7 million) from a consortium that includes electrical equipment manufacturer Harju Elekter Group and Baltic investment firm UP Invest. The company plans to use the funds to ramp up production of its graphene-based ultracapacitors. Customers include hybrid […]

It’s not just cars that are getting electrified – guns may be going high-tech as well. The Office of Naval Research (ONR) has ordered a battery system from K2 Energy Solutions to be used in an electromagnetic rail gun, part of an $81,400,000 contract. Rail gun technology uses electromagnetic energy […]

Chemists at Canada’s University of Waterloo have described a key mediation pathway that explains why sodium-oxygen batteries are more energy-efficient compared with their lithium-oxygen counterparts. “Our new understanding brings together a lot of different, disconnected bits of a puzzle that have allowed us to assemble the full picture,” says Professor […]

Like Tesla, Daimler will start offering energy storage solutions, according to recent reports. They will be commercially available in September. In 2009, Daimler founded the subsidiary ACCUmotive to develop lithium-ion batteries for its plug-in hybrids, electric vehicles, and smart vehicles. Since then, solar power costs have decreased and the energy […]

The British firm Faradion is working on sodium-ion batteries, which show promise as a successor to Li-ion technology. In collaboration with Williams Advanced Engineering, which provided batteries for the Formula E electric race car, Faradion has built a sodium-ion-powered electric bike to prove the concept. Sodium-ion intercalation batteries use the […]
