At 500 W h/kg, Sion’s battery has twice the energy density of a traditional lithium-ion one, the firm claims. And another US start-up, Battery Streak, developer of a fast-charging lithium-ion battery featuring niobium, has sold a 20% stake to the Brazilian niobium producer Companhia Brasileira de Metalurgia e Mineração. The firms have formed a partnership with the goal of accelerating the use of niobium in lithium-ion batteries. Technology being developed by Battery Streak and others holds the promise of decreasing battery pack costs while increasing performance. A recent BloombergNEF report predicts that by 2024, cost reductions across the sector should push average battery prices below $100 per kW h. BloombergNEF estimates that since 2010 lithium-ion battery prices have fallen 89% in real terms to $132 per kW h in 2021. /business/start-ups/Battery-partnerships-surge/99/i44 20211202 Auto industry is buying into next-generation technology for electric vehicles Concentrates 99 44 /magazine/99/09944.html Battery partnerships surge battery, lithium-ion, niobium con bus Alex Scott business start-ups energy energy-storage- ,,,,,, Factorial Energy says this prototype is the biggest solid-state electrolyte battery cell the industry has yet made.,Factorial Energy,A prototype electric vehicle battery.,Batteries electric vehicle , Battery partnerships surge Chemical & Engineering News Battery partnerships surge Battery partnerships surge Battery partnerships surge

—Thin-film battery breaks energy storage record “Careful manufacturing yields a lithium-ion battery for compact medical devices” A tiny new battery that packs an energy punch could power more compact next-gen pacemakers and other medical devices. The LiCoO2 battery was developed by researchers at CEA-Leti, part of the French atomic energy agency. Battery chemist Sami Oukassi says it has a higher energy density than any thin-film battery reported so far. The battery is just 3.10 by 1.70 mm in area—which doesn’t leave much room for energy-storing electrode materials. Oukassi says his group improved the thin-film battery’s performance by making a thicker layer of LiCoO2 at higher yield.

Lithium-air batteries look great on paper. In theory, they can pack roughly 10 times as much energy per weight as conventional lithium-ion batteries such as the ones that power cell phones. But the “air breathing” devices haven’t made it out of the lab yet because they fail quickly. These batteries are also inefficient electrically in that the voltage required to charge the battery is higher than that obtained while using the battery. In air-breathing batteries, the oxygen needed for electrochemical reactions comes from the air and reacts with lithium inside the battery, forming lithium oxides, mainly lithium peroxide (Li2O2). That compound is one of the keys to Li-air batteries’ weight advantage: It has a much lower molecular weight than the transition-metal lithium oxides, such as LiCoO2, used in Li-ion batteries.

—Molten Electrolyte-Air Battery Debuts “Uncommon electrochemical reactions may lead to batteries with exceptionally high charge capacities” One factor impeding wide use of electric vehicles is their limited driving range per charge compared with the driving range per fill-up of petroleum-fueled vehicles.

—Solid-state batteries inch their way toward commercialization “Small battery makers hope to prove lithium-ion alternatives’ worth by first energizing internet of things devices” Though still a nascent technology, solid-state batteries are hot right now. Among the most prominent proponents is Toyota, which aims to commercialize solid-state batteries for electric cars by 2022.

Billions of batteries are used every day without incident, but when batteries do catch fire, common causes include a short circuit across the battery separator, a porous polyethylene film which is supposed to prevent battery electrodes from touching. Batteries can also overcharge or experience a chemical breakdown of their flammable carbonate-based electrolytes.

—Battery recycling system starts to take shape “But it could take a decade before there’s a steady stream of used electric vehicle batteries” Companies focused on battery recycling are launching operations at large-scale factories capable of processing batteries from electric vehicles. A joint venture connected to the Swedish battery maker Northvolt has started up Europe’s biggest battery recycling facility, capable of processing 25,000 electric car batteries per year. The facility, in Norway, will get batteries from the country’s well-developed electric vehicle market and supply Northvolt’s factories with black mass, a mixture of lithium, cobalt, nickel, and other battery metals. Meanwhile, Li-Cycle has opened a battery recycling plant in Arizona, a state the Canadian company hopes will become a hub for electric vehicle manufacturing.

—Batteries that breathe air “Rechargeable zinc-air batteries are going mainstream, but other metal-air chemistries will have to wait awhile” Last year, zinc-air battery start-up Fluidic Energy installed backup batteries for an array of solar panels in Welay Selatan, a tiny village on the Indonesian island of Alor.

—Lead makers fight to stay in batteries “Lead industry claims the metal can beat lithium in a new kind of electric hybrid vehicle” Tesla, BMW, and other manufacturers of advanced electric cars have long bypassed lead-acid batteries as their power source and opted for more expensive but better-performing lithium-ion batteries.
