Amprius Announces 10X Capacity Expansion At Its Fremont, California Battery Production Facility
Fremont, California-based Amprius technologies is the manufacturer of some of the highest energy density lithium-ion battery cells in the world. This was accomplished using their proprietary silicone nanowire anode technology that enables a step change improvement over the traditionally graphite-based lithium-ion cell chemistries. Higher energy density and volumetric density matters … [continued]
What Do Battery Energy Density Improvements Really Mean For Trucks, Ships, & Planes?
The future of all ground transportation and an awful lot of aviation and marine shipping being electric, low-carbon, quieter, and a lot less smelly is within reach. It would be rude not to reach out and grab it with both hands.
Tesla & Amprius — What Is Going On? [Updated: Nothing]
Tesla fans have zeroed in on a battery startup called Amprius. A number of clues indicate that it may be acquired by Tesla in the future, or that it at least plays a role in Tesla’s battery innovation and coming announcements at Tesla Battery Day. I’ll come back to the Tesla–Amprius connections in a minute. First, once I saw the name popping up, I recognized it and decided to check the CleanTechnica archives for it. Let’s start there.
43 Battery Storage Companies To Watch
As I wrote in my piece on cleantech trends from 2014 and expected cleantech trends in 2015, the battery storage market is really blossoming. There are now quite a number of battery startups and battery departments within big corporations that seem to have promising products arriving on the market or soon to arrive … [continued]
Don’t Look Now, But Your Next EV Battery Could Look Like A Pomegranate
Lithium-ion batteries have been the gold standard for powering electric vehicles, but with fuel cells breathing down their necks, the pressure is on to come up with next-generation performance improvements. A team of researchers has come up with a solution based on the structure of a pomegranate, which could combine … [continued]
Former US Secretary Of Energy Steven Chu Joins Amprius Board
One of the top energy storage startups we’re keeping an eye on these days is Amprius. The lithium-ion battery company, a Stanford University spinoff, recently landed $30 million in Series C funding. Adding former US Secretary of Energy Steven Chu to the board of directors is clearly another positive step forward. … [continued]
Amprius Raises $30 Million To Commercialize Li-ion Batteries
Amprius, a lithium-ion battery manufacturer, has raised $30 million of Series C funding for new, compact lithium-ion batteries which utilize silicon nanowire anodes. In the past, silicon anode technology has experienced multiple failures, but also improvements — as have most other technologies, proving that alternative energy technologies in general deserve … [continued]
New Battery Research: Double-Walled Nanotubes Improve Durability and Lifetime
For more than a decade, scientists have tried to improve lithium-based batteries by replacing the graphite in one terminal with silicon, which can store 10 times more charge. But after just a few charge/discharge cycles, the silicon structure would crack and crumble, rendering the battery useless. Now a team led … [continued]
