Wildcat and TIES collaborate on electrolytes for high energy-density Li-ion batteries

Wildcat Discovery Technologies is working with the Tianmu Lake Advanced Energy Storage Technology Institute (TIES) in a new multi-year project geared towards the development and optimization of high energy-density lithium-ion batteries. Wildcat will use its high-speed testing capabilities to provide TIES with as much data as possible. In turn, TIES’s team (headed by Professor Hong Li),… Read more »

Waterloo researchers achieve reversible four-electron conversion with lithium-oxygen batteries

Scientists from the University of Waterloo have devised several new electrochemical processes which greatly increase the lifespan and stability of lithium-oxygen batteries. On paper, Li-O2 batteries have high energy densities and low weights. However, they also have internal reactions (involving superoxides and peroxides) that slowly corrode their carbon cathodes. The superoxide also destroys organic electrolytes in the… Read more »

Axion, Aceleron and Aspire launch battery recycling and reuse initiative

Circular economy and resource recovery specialists Axion, Aspire Engineering and Aceleron have launched an initiative to tackle the growing number of end-of-life EV batteries. They are currently providing a recovery service that begins with Aspire processing the batteries for remanufacturing, reuse and recycling. Next, Aceleron tests and repurposes the batteries. If the batteries cannot be reused, Axion will then… Read more »

Tydrolyte releases low-corrosion, low-toxicity electrolyte alternative for lead-acid batteries

Electrolyte specialist Tydrolyte has released an electrolyte intended to replace the sulfuric acid found in lead-acid batteries. It claims that the patent-pending electrolyte is well suited for start-stop batteries, offers lower hold currents and water losses and is less toxic than sulfuric acid. Start-stop batteries must induce 100 times as many engine ignitions as a conventional… Read more »

Canada funds Nano One’s Li-ion durability improvement research

The National Research Council of Canada Industrial Research Assistance Program (NRC IRAP) has granted Nano One’s “Coatings for High Durability Lithium-ion Battery Cathodes” project $349,000 in non-dilutive and non-repayable funds. The project is intended to study various coatings and dopants that can reduce or remove instabilities in cathode materials. Nano One intends to focus its resources… Read more »

ZAF to use $300,000 grant to increase production of nickel-zinc batteries

Nickel-zinc (NiZn) specialist ZAF Energy Systems has received $300,000, the first installment of a $600,000 investment from Missouri’s Department of Economic Development. With the new funding, ZAF will increase production capacity to meet the increasing demand for its NiZn batteries. The company claims that the batteries have double the storage capacity and triple the power… Read more »

AKASOL begins mass production of batteries for Mercedes eCitaro electric bus

This fall, AKASOL is set to begin mass producing batteries for Mercedes-Benz’s eCitaro. AKASOL’s first-generation battery systems will contain ten battery modules for up to 243 kWh per vehicle and a charging rate of up to 300 kW. In order to make this possible, AKASOL uses a water-cooling system to keep its batteries at 25° C in various… Read more »

Tokyo Tech introduces fabrication process for low-resistance solid-state batteries

Solid-state batteries are theoretically safer, more stable, and have higher energy densities than conventional Li-ion batteries with liquid electrolytes. Unfortunately, they also tend to have relatively high resistance at the interfaces between their electrodes and solid electrolytes, which can limit the rate of charging and discharging. In order to solve this, researchers from the Tokyo… Read more »

Sila Nano raises $70 million in funding for silicon-dominant battery anodes

Battery specialist Sila Nanotechnologies has received $70 million in Series D funding from Sutter Hill Ventures, Next47 (backed by Siemens), and Amperex. Sila Nano will use the funding for the development and commercialization of its silicon-dominant anodes. Overall, Sila has raised $125 million from investors including Bessemer Venture Partners, Chengwei Capital, Matrix Partners, Samsung, and… Read more »

Carnegie Mellon creates new method to 3D print battery electrodes

Porous electrodes have been 3D printed in the past using extrusion processes in which a strand of material is extruded from a heated nozzle. Interdigitated, or clasped, structures created with this technique provide space for ion flow, but their limited geometries are quite inefficient. Carnegie Mellon University’s new research has developed a completely different additive process… Read more »
