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 »

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 »

New coating beefs up performance of lithium-sulfur batteries

New types of electrodes – positive and negative terminals – are considered essential for the development of a new generation of high energy-density batteries. As lithium-ion batteries begin to reach their capacity limits, many researchers are looking at lithium-sulfur as a solution. Sulfur is both lightweight and abundant, with a high theoretical energy capacity. However,… Read more »

Toshiba’s new SCiB battery module for AGVs

Toshiba’s latest addition to its SCiB line of lithium-ion batteries, the SIP series of modules for automated guided vehicles (AGVs), will be available in April. AGVs are mobile robots used to transport materials around factory floors, warehouses, hospitals and offices. Most current AGVs use lead batteries, which suffer from long charge times and short lifecycles…. Read more »

Battery prelithiation shortens costly formation time

Before a lithium-ion battery is installed in a vehicle, it must undergo a lengthy process called formation, in which it is charged and discharged to control the initial chemical reactions with lithium. Many of these reactions are irreversible and permanently decrease the battery’s available energy. The process requires expensive lithium to be part of the… Read more »

NH Research raises the voltage of its battery test systems

NH Research has released a higher-voltage, higher-power version of its single-channel 9210 series battery test system. The 9210 Series provided a 12 kW power module operating at 40, 120 or 600 Volts, which allowed paralleling with similar systems to increase the power. The new 9300 system provides a 100 kW power module with a software-selectable… Read more »

FDK and Fujitsu develop novel cathode material for solid-state batteries

FDK and Fujitsu Laboratories have jointly developed lithium cobalt pyrophosphate (Li2CoP2O7) as a cathode material for solid-state lithium-ion batteries. The new material can operate at charge/discharge voltages of more than 5 V, which is beyond the limits of current lithium batteries. The energy of a battery is a function of its voltage and capacity, so an… Read more »

Southwest Research Institute consortium conducts independent battery benchmarking

Comparing the spec sheets from different parts manufacturers is tricky business for engineers in any industry. However, the advanced battery market seems to be uniquely challenged in this regard. As Tesla CEO Elon Musk often points out, when it comes to batteries, the BS factor is outrageous. Even if you assume that every vendor provides… Read more »
