—GM Expands Michigan Battery Laboratory “” General Motors has more than doubled the size of its battery systems laboratory in Warren, Mich., to 85,000 sq ft. The facility is used to test battery packs and battery cells for GM cars such as the Chevrolet Volt, Chevrolet Spark EV, and Cadillac ELR. In addition to increased capacity for testing, the lab features equipment to develop components such as chargers and to prototype new battery packs for vehicles in development. Work at the lab will help increase battery performance while decreasing costs, according to GM. /articles/91/i38/GM-Expands-Michigan-Battery-Laboratory.html 20130923 Concentrates 91 38 /magazine/91/09138.html GM Expands Michigan Battery Laboratory electric vehicles, electric-car batteries con bus Melody M.

—New Lithium-Ion Battery Woes “Safety: Airplane battery fires thrust electrochemistry safety back in the spotlight” Questions about the safety of using lithium-ion batteries for transportation applications have hit a zenith with two incidents in which such battery units onboard Boeing 787 Dreamliner airplanes caught fire or began to smolder.

—Rechargeable battery weathers extreme cold conditions “Batteries that work at super low temperatures could power devices in space and the Arctic” Rechargeable batteries perform poorly when it’s cold out. Now researchers have designed a new lithium-ion battery that still works at –70 °C. Such batteries could improve the performance of electric cars in winter, and help power high-altitude machinery, space stations, and planetary rovers (Joule 2018, DOI: 10.1016/j.joule.2018.01.017). On cold winter days, electric vehicles can lose half their driving range due to poor battery performance. At –40 °C, lithium-ion batteries retain just 12% of their capacity. So in the Arctic, at high altitudes, and in space, rechargeable batteries must be insulated and heated, or non-rechargeable batteries or supercapacitors must be used instead.

—Developing anodes for sodium-ion batteries “ ” The sodium-ion battery start-up Faradion has formed an R&D partnership with the oil refiner Phillips 66 on anode materials for sodium-ion batteries. The partners aim to leverage Phillips 66’s expertise in carbon materials to develop a suitable hard-carbon anode for Faradion batteries. The start-up’s sodium-ion batteries are less energy dense than those based on lithium chemistry, but they are cheaper and safer. /energy/energy-storage-/Developing-anodes-sodium-ion-batteries/99/i8 20210307 Concentrates 99 8 /magazine/99/09908.html Developing anodes for sodium-ion batteries anode, carbon, sodium-ion con bus Alex Scott energy energy-storage- Phillips 66 senior engineer Liang Zhang tests small batteries to evaluate carbon products as sodium-ion battery anode materials.,Phillips 66,A photo of a person doing battery research.,Batteries sodium-ion anode R&D , Developing anodes for sodium-ion batteries The Chemical & Engineering News Developing anodes for sodium-ion batteries Developing anodes for sodium-ion batteries Developing anodes for sodium-ion batteries

What is a zinc bromide battery? OK, let me start by first explaining what’s normally in a battery. A battery basically consists of two electrodes. A chemical reaction occurs inside the battery, and electrons are transferred from one reactant to the other by oxidation at one electrode and reduction at the other.

—High-performance textile batteries made by the spool “Robust coating method produces lithium-fiber batteries that can recharge a cell phone” Researchers have mass-produced meters of fiber-shaped lithium batteries using standard industrial equipment (Nature 2021, DOI: 10.1038/s41586-021-03772-0). The high-performance fiber batteries pack more than 80 times as much energy by weight than previous ones.

Their metal-free battery uses an organic polypeptide backbone for its electrodes, which the scientists can degrade with acid into amino acids for potential reuse (Nature 2021, DOI: 10.1038/s41586-021-03399-1). The design is a step toward a circular battery life cycle, in which batteries could be degraded and rebuilt without entering the waste stream. This offers an improvement over batteries made from nondegradable organic polymers, another approach for eliminating metals from batteries. These organic polymer batteries would likely have the same fate as other plastics, Wooley says. “More than 90% of the plastics that could be recycled are not.”
