Sponsored by OCSiAl Group Li-ion batteries represent the most dynamic and fastest growing battery market, with total sales of $10 billion in 2015 [i]. Historically, the primary challenge for battery manufacturers has been the constant demand for greater energy density, both volumetric and gravimetric. Li-ion’s dramatic rise is in large part due to solving this challenge more… Read more »

Molecular pulley leads to silicon anode breakthrough
Silicon anodes are receiving a great deal of attention, as they can enable batteries to deliver 3-5 times higher capacities compared with current graphite anodes. Although silicon is abundant and cheap, Si anodes have a limited number of charge-discharge cycles – typically less than 100 times. Their volume expands enormously during each cycle, leading to… Read more »
Argonne NL licenses continuous ALD technology to Forge Nano
Argonne National Laboratory has granted an exclusive license to Colorado-based nano-coating specialist Forge Nano to commercialize Argonne’s patented system for continuous atomic layer deposition. Atomic layer deposition (ALD) is a process that deposits a uniform, ultrathin encapsulating coating around any material. It can be used to upgrade materials such as powders utilized in lithium-ion batteries,… Read more »
New fluorinated sulfone electrolytes enable high-voltage, high-energy Li-ion batteries
Researchers at Argonne National Laboratory have synthesized a new class of fluorinated sulfone electrolytes to enable high-voltage, high-energy Li-ion batteries. In “Oxidatively Stable Fluorinated Sulfone Electrolytes for 5-V Lithium-ion Battery,” published in the RSC journal Energy & Environmental Science, Chi-Cheung Su and colleagues explain how they evaluated the physical and electrochemical properties of the new… Read more »
ECO COMBAT project aims to develop better and more sustainable batteries
Ten European industry and research organizations are partnering in the EU-funded project ECO COMBAT (Ecological Composites for High-Efficient Li-Ion Batteries), which aims to develop next-generation Li-ion batteries. Better performance is not the only goal for the new battery. The project also aims to develop a battery that’s more sustainable, by reducing the need for expensive… Read more »
Seaworthy EVs: Leclanché designs and manufactures Li-ion cells and systems
The advantages of electrifying transportation are far-reaching. Advanced energy storage systems are even making their way into the commercial marine industry. There are many marine applications in which adding a large Li-ion battery pack makes a lot of sense. The best-use case varies depending on the boat size and purpose. All-electric ferries, for example, are… Read more »
Saint Jean Carbon sets out to show that Li-ion materials can be recycled over and over again
Saint Jean Carbon, a carbon science company with interests in graphite and lithium mining, plans to join with a battery manufacturing partner to build a full-scale lithium-ion battery using recycled material from an EV power pack and upcycled anode material. The project aims to show that battery materials can be re-used over and over again,… Read more »
Leclanché and Narada Power form strategic alliance for Li-ion technology
Swiss battery manufacturer Leclanché and China-based battery manufacturer Zhejiang Narada Power Source have announced a strategic partnership to manufacture and develop lithium-ion battery technology for the Chinese and global markets. Narada aims to achieve low-cost, scale manufacturing of Leclanché’s proprietary high-cycling and fast-charging lithium titanate (LTO) and high-energy-density graphite nickel manganese cobalt (G-NMC) battery technologies….

Researchers increase energy density by eliminating first-cycle capacity loss
In the quest to increase the energy density of Li-ion batteries, Yuan Yang, an Assistant Professor at Columbia Engineering, has developed a novel approach: reducing or eliminating capacity loss that occurs when a battery is first manufactured. In a paper recently published in Nano Letters, Yang and colleagues explain how this new method could improve… Read more »
Ethylene carbonate-free electrolytes promise less oxidation and better-performing Li-ion cells
A team led by celebrated battery boffin Professor Jeff Dahn at Dalhousie University has demonstrated that a common electrolyte additive is detrimental for Li-ion cells at high voltages, and suggest some alternatives. Dahn and his team discuss their latest work in two papers: “Enabling linear alkyl carbonate electrolytes for high voltage Li-ion cells,” published in… Read more »
