Accelerated electrode drying could reduce battery production cost
A new EPIC project coordinated by Karlsruhe Institute of Technology (KIT) is aimed at accelerating the drying of electrodes for lithium-ion batteries, increasing the energy efficiency of this process and reducing production cost. KIT says innovative electrode drying management can reduce the cost of battery production and improve environmental performance. The quality of Li-ion battery… Read more »
Teardown expert Sandy Munro compares Tesla, Nissan, Jaguar inverters
When it comes to automobiles, Sandy Munro knows whereof he speaks. His company specializes in taking new cars apart and analyzing every little bracket and screw—what it’s made of, who made it, and how much it cost. Charged was fortunate enough to have Sandy present a couple of video sessions at our Virtual Conference on… Read more »
Teardown expert Sandy Munro compares 10 leading EV motors in new video
Auto manufacturing expert Sandy Munro knows what makes cars tick. For years, he and his company have performed teardowns, taking new cars apart and analyzing every little bracket and screw—what it’s made of, who made it, and how much it cost. This week at the Charged Virtual Conference on EV Engineering, Sandy compared an assortment… Read more »
Oxis Energy’s ultralight Li-sulfur batteries are aimed at aviation
Oxfordshire-based Oxis Energy has been working on lithium-sulfur battery technology since 2004 (Charged has reported on the company several times over the years). In a recent article in IEEE Spectrum, the company’s Head of Battery Development and Integration, Mark Crittenden, explains why lithium-sulfur tech is uniquely suited to electric aviation. Weight is a critical constraint… Read more »
Elon Musk expects manufacturing to be Tesla’s ace in the hole
Tesla is increasing its focus on perfecting its manufacturing process. As Zachary Shahan writes in a recent CleanTechnica article, “the machine that builds the machine” just may be Elon Musk’s favorite phrase these days. In fact, Musk expects Tesla’s manufacturing prowess to give it an edge over other EV-makers. “Tesla’s long-term competitive advantage will be… Read more »
The technical challenges of bidirectional chargers
For years, we’ve been hearing about an EV technology that promises to be a game-changer: Vehicle-to-Grid (V2G) bidirectional charging. My recent work with one V2G charger developer, Fermata Energy, has convinced me that V2G has found its proverbial killer app: load peak shaving for commercial/industrial energy customers. This article is going to concentrate on the… Read more »
Li-Cycle recovers usable battery-grade materials from shredded Li-ion batteries
Q&A with CEO Ajay Kochhar It’s usually one of the first objections cited by EV naysayers: batteries can’t or won’t be recycled, and they contain hazardous materials that will end up in landfills. In fact, no such sinister scenario is likely—most of the components of Li-ion batteries are valuable, and it’s quite feasible, technically and economically,… Read more »
Shoppers buy more EVs if they understand charging—and now there’s proof (exclusive first look)
New-car salespeople have simple motivations: They want to spend the least time selling you a new car for the highest possible commission. You buy a new car every five years or so; they sell up to 25 cars a month. They make money on the difference in knowledge. That makes electric cars a problem: they… Read more »
Use of aluminum growing faster than any other automotive material
A new survey reports that the use of aluminum is growing faster than that of any other automotive material, and is expected to grow to content levels of 514 pounds per vehicle (PPV) by 2026, up 12% from 2020 levels. The survey, conducted by DuckerFrontier, analyzes the latest information on material content for North American… Read more »
