Leclanché’s new marine battery system earns international certification

Swiss battery-maker Leclanché’s new Marine Rack System (MRS), a modular Li-ion battery system, has won approval by the international certification body DNV-GL. Leclanché will use the MRS on the E-ferry in Denmark, the world’s largest electric ferry, which is equipped with a 4.3 MWh Leclanché lithium-ion battery, and is scheduled for launch later this year….

AKASOL opens two new production facilities for battery systems

German battery builder AKASOL has built two new production sites: a new facility with over 3,000 square meters of production halls and office space in Langen, as well as an additional 700 square meters of production space at the company’s headquarters in Darmstadt. The automated production line in Langen will be set up by the… Read more »

EV tech explained: Why do EVs restrict the amount of battery capacity that can be used for driving?

All EVs that use lithium-ion batteries are designed so that their full capacity can’t be used in driving – a few kWh are always left over as a buffer. Sometimes you’ll find this figure in spec sheets, which might (for example) quote capacity as “60 kWh (55 usable)” or some such. What is the reason… Read more »

Adding quartz powder to Li-S battery electrolyte slows capacity loss

Researchers at the Paul Scherrer Institute (PSI) in Switzerland and the Université Grenoble Alpes in France have developed a simple method that they say can improve the performance of lithium-sulfur batteries by 25-30%. In “Direct observation of lithium polysulfides in lithium-sulfur batteries using operando X-ray diffraction,” published in Nature Energy, Joanna Conder and colleagues reported… Read more »

Forge Nano to commercialize NREL-developed solid electrolyte coatings

The DOE’s National Renewable Energy Laboratory (NREL) has entered into an exclusive license agreement with Forge Nano to commercialize NREL’s patented battery materials and systems. A feature of the technology is the encapsulation of materials with solid electrolyte coatings that can be designed to meet the needs of any battery application. These batteries feature a… Read more »

Microvast Power Systems raises $400 Million in new funding

Microvast Power Systems (MPS) has received $400 million in a funding round led by CITIC Securities. MPS is a vertically integrated battery system manufacturer. Its battery systems are currently powering over 15,000 electric and hybrid public transport vehicles in over 140 cities. MPS plans to launch a next-generation product line this year, and began construction… Read more »

Using enzymes to inhibit battery aging

Biologists have long considered the excited oxygen molecule singlet oxygen to be the main cause of aging in cells. To counter this, nature uses an enzyme to eliminate superoxide as a free radical. Superoxide also occurs in cell respiration for energy production. Stefan Freunberger of the Graz University of Technology in Austria has found parallels… 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 »

Grafoid’s ion-selective graphene polymer membrane protects electrodes

Canadian graphene specialist Grafoid has introduced its GPURE Graphene Polymer nano-porous membrane, intended for next generation Li-ion battery applications. The GPURE GPM product is a chemically inert, freestanding membrane that uses graphene composites to test ion selectivity using both monovalent and divalent ions. Ion selectivity is a key requirement for a semi-permeable membrane in a… Read more »
