New stack design for cheaper redox flow batteries

German scientists have proposed a new design for stacks used in redox flow batteries. Through a powder-to-roll process, a device that weighs 80% less than a conventional stack was fabricated.

Recycling rare-earth elements from dead lithium batteries

American Resources Corporation is developing a process to separate pure rare earth metals from lithium-ion batteries used in electric vehicles or power plants based on renewable energy. The technique is described as a two-zone ligand-assisted displacement chromatography (LAD) that is able to produce metals with high yields and purity of over 99%.

Solid-state battery maker picks up $130 million investment

US based battery company Solid Power announced that it has received $130 million in new funding from investors including Ford and BMW. With this backing, the company plans to begin pilot scale production of solid-state lithium-ion batteries suitable for electric vehicles early next year.

Tesla touts the market strength of its Powerwall energy storage product

In an earnings call, the company said that storage deployments grew 71% YoY and solar installations were its strongest in 2.5 years.

Enabling aluminum in batteries

Scientists in South Korea and the UK demonstrated a new cathode material for an aluminum-ion battery, which achieved impressive results in both specific capacity and cycle life. The material allows researchers to better take advantage of aluminum’s energy storage characteristics, and produce batteries with much higher capacity.

Battery testing builds certainty

Owners and operators of energy storage systems, as well as investors, need transparent ways to evaluate battery performance. They need certainty that the selected batteries for their ESS projects will perform reliably, have predictable life expectancies, and meet projected revenue and contractual obligations over their lifetimes. The economic viability of entire projects depend on this confidence, writes Michael Kleinberg of DNV.
