Toray Industries, a Japanese performance chemical manufacturer, has developed an ion-conductive polymer membrane that it says delivers 10 times the ion conductivity of its predecessors. The new polymer membranes offer ion conductivity through hopping conduction. This mechanism enables lithium ions to traverse between interacting sites within polymer membranes, jumping across sites. The membranes remain non-porous…. Read more »

Aqua Metals is building a more sustainable battery recycling ecosystem
Q&A with Aqua Metals execs Steve Cotton and David Regan Regardless of the claims made in Facebook memes, Li-ion batteries are eminently recyclable, and current recycling methods cause far less environmental damage than the well-documented depredations of the petroleum industry. However, as sustainability is central to the mission of the EV industry, we need to… Read more »
ION Storage Systems achieves milestone with its anodeless solid-state battery
ION Storage Systems, a Maryland-based manufacturer of solid-state batteries, has announced that its anodeless and compressionless SSB achieved a key threshold with its first market deployment with the US military. ION says its SSB successfully exceeded 125 cycles with less than 5% capacity degradation in performance, offering the potential for more than 1,000 cycles in… Read more »
QuantumScape introduces a new cell format for solid-state EV batteries
QuantumScape, a US battery company, has introduced a new cell format, FlexFrame, for solid-state EV batteries. FlexFrame combines pouch and prismatic cells. The FlexFrame architecture has a frame that wraps around the cell stack and a flexible polymer laminate outer layer like pouch cells. The cell is anode-free and the cell stack is contracted, with… Read more »

NOVA, the partnership and venture capital branch of building materials company Saint-Gobain, has invested in solid-state lithium metal battery company ION Storage Systems to expand their battery technology collaboration. The companies are working to establish US manufacturing of ceramic material for large-scale solid-state battery electrolyte manufacturing. In September, ION announced a multi-year supply arrangement with… Read more »
Sion Power raises 75 million to commercialize its Licerion EV battery tech
Sion Power, a developer of next-generation batteries for EVs, has secured $75 million in Series A funding. The round was led by battery manufacturer LG Energy Solution, and included participation from Euclidean Capital and Hillspire. Sion Power’s Licerion technology uses compression in a lithium metal battery to enhance safety, lifetime and recharging rates. Sion has… Read more »
Li-Metal demonstrates electrolyte reconditioning process for carbonate-to-metal tech
Li-Metal, a developer of lithium metal anode and lithium metal production technologies, has demonstrated an electrolyte reconditioning process that it calls “a pivotal component supporting Li-Metal’s patented and modular carbonate-to-metal (C2M) technology for lithium metal production.” The electrolyte reconditioning process plays a crucial role in the closed-loop operation of Li-Metal’s C2M technology, by facilitating the… Read more »
QuantumScape prototype Li-metal cell retains 95% discharge energy over 1,000 cycles
QuantumScape, a US battery company, has announced that its 24-layer A0 prototype cell retained over 95% discharge energy over 1,000+ full cycle equivalents in lab testing. QuantumScape stated that no automotive-format lithium-metal battery has exhibited this discharge energy retention across a similar cycle count at room temperature and modest pressure. The single-layer cells that QuantumScape… Read more »
Researchers announce cycle life breakthrough for lithium-sulfur EV batteries
Researchers at Monash University have developed a new lithium-sulfur battery design with a nanoporous polymer-coated lithium foil anode that reduces the amount of lithium required in a single battery. In their recent paper, the scientists explain how they applied a nanoporous polymer directly onto a lithium foil anode, creating a new battery design that uses… Read more »
