Molten-Salt Battery Freezes Energy Over a Whole Season

Cars That Think

While rechargeable batteries are the solution of choice for consumer-level use, they are impractical for grid-scale consideration. Scientists have been looking for solutions in gravity energy storage , thermal or geothermal storage , and also molten-salt batteries.

New long-duration, extended capacity Na-Al battery design for grid storage

Green Car Congress

Researchers led by the Department of Energy’s Pacific Northwest National Laboratory (PNNL) have extended the capacity and duration of sodium-aluminum batteries. The new sodium-based molten salt battery uses two distinct reactions. The team previously reported a neutral molten salt reaction. Weller et al.

UCSD researchers improve method to recycle and renew used cathodes from Li-ion batteries via eutectic molten salts

Green Car Congress

Researchers at the University of California San Diego have improved their recycling process that regenerates degraded cathodes from spent lithium-ion batteries. Illustration of the process to restore lithium ions to degraded NMC cathodes using eutectic molten salts at ambient pressure. —Zheng Chen.

PNNL: single-crystal nickel-rich cathode holds promise for next-generation Li-ion batteries

Green Car Congress

High-energy nickel (Ni)–rich cathode will play a key role in advanced lithium (Li)–ion batteries, but it suffers from moisture sensitivity, side reactions, and gas generation. Nickel offers relatively low cost, wide availability and low toxicity compared to other key battery materials, such as cobalt.

Novel Li-metal electrode design could lead to more powerful solid-state batteries

Green Car Congress

Researchers at MIT and their colleagues are proposing a new design for electrodes that, based on the long-sought goal of using pure lithium metal as the anode, could lead to longer-lived batteries with higher energy densities. The metal then shrinks again during discharge, as the battery is used.

Lux Research: grid storage battery cost to fall to $500/kWh by 2022, short of expectations

Green Car Congress

Lithium-ion and molten-salt battery costs will approach $500/kWh by 2022, reducing the high capital cost of emerging grid storage technologies. Molten-salt batteries hold the most potential to be the cheapest large-scale systems, with manufacturing improvements playing the largest role, accounting for 95% of the cost reduction.

The Case for Nuclear Cargo Ships

Cars That Think

Hedging its bets, the industry is exploring ammonia, batteries, and hydrogen, among other options for powering ships. Vard Group is part of NuProShip , a consortium of the Norwegian maritime authority, universities, shipbuilders, and shipping companies that aims to develop a Generation IV reactor for marine vessels.
