How Silicon Anode Batteries Will Bring Better Range To EVs
Lithium-ion battery performance has reached a plateau in recent years, but a breakthrough in battery technology is about to change that. Using silicon instead of graphite, the commonly used material in battery anodes today, enables significantly higher energy density and faster charging. The new tech has attracted the attention of big players such as GM, Porsche, Mercedes-Benz and Airbus. CNBC spoke with three companies working on silicon anodes — Sila Nanotechnologies, Amprius Technologies and Group14 Technologies, to learn how the new batteries will transform electric vehicles, consumer electronics and more.

Why The Auto Industry Is Betting On Silicon Anode Batteries
source
AI data centers are driving unprecedented demand for electricity and putting renewed pressure on America’s power grid to modernize its equipment and develop greener, more efficient sources of power. Google, Meta, Microsoft and Amazon are all spending millions of dollars on local infrastructure upgrades and companies like SpaceXAI are even building off-grid power plants to power their data centers.
Google says its planned 780-megawatt data center in Pine Island, Minnesota, could offer a model for powering the AI boom. In a proposed agreement with Xcel Energy, Google says it will support 1,900 megawatts of new wind, solar and battery capacity, while minimum payments and exit fees are intended to protect local ratepayers if demand falls short.
CNBC examines whether projects like Pine Island can make the grid cleaner without shifting costs to existing customers, why some energy experts argue that smaller data centers could make better use of infrastructure already in place, and how utilities’ financial incentives can complicate efforts to build less.

The Race To Power AI Is Reshaping America’s Electric Grid

A leak by Indian supplier Tata Electronics, purportedly of the yet-to-be-released iPhone 18 Pro models, has become marketing gold for the Chinese government. The Communist Party paper, The Global Times, is using the leak – caused by a cyberattack – as a cautionary tale for Apple and other American companies that are in the process of diversifying their supply chains away from China. CNBC’s Eunice Yoon reports.
00:58 Correction: The location tag should be Beijing, China.

China’s Swagger After India’s iPhone 18 Leak
source
Unstoppable demand for AI is leading to a capacity crunch on factory lines at the world’s leading chip manufacturer, Taiwan Semiconductor. And it could put a chokehold on AI’s ability to scale. Analysts tell CNBC that Nvidia, Apple, Broadcom, AMD and others are locked in an “extremely fierce” competition to get their GPUs, CPUs and custom AI chips made at TSMC. Capacity can’t come online fast enough, despite TSMC’s rush to build new fabs in Taiwan, Japan and Arizona, where has expanded investment to $265 billion. The strain has made one man at TSMC “the most popular person on the planet,” as chip start-ups and big name CEOs visit Taiwan to ask him for wafer allocation. It’s also created a rich opportunity for Intel, as customers look to the long-struggling foundry arm of the U.S. chip manufacturer for a second source.

@slipperyeel9206
December 17, 2023 at 12:09 am
full self driving cars with a robo-taxi service will reduce the demand for cars while still delivering the same amount of people-miles each year. robotaxis, along with battery tech like this, will be a game changer because it could reduce the cost of a taxi service to well below the cost of driving an owned vehicle. it will make cities cleaner, safer, and more efficient. So you won't a hundred millions cars sold in the US each year anymore, you will only need maybe 1 million cars produced each year

An interesting review of silicon anode batteries, but seriously runs short on what´s going on. Theres also a silicion anode battery manufacturer that runs by the name of ENOVIX, and are running into actual production at a larger scale on year 2024. In late 2023 they will be supplying the US ARMY with their batteries, which have been positively tested for military use: a highly demanding application.🙂

Guy argues that if every car made was electric, it would be a 1 trillion dollar market, that means the average battery price per vehicle would be over $50k! And THAT is exactly why it is. Average price would have to approximate average engine/transmission prices, so less than $20k

@paritoshdoshi3202
December 17, 2023 at 12:09 am
Its not just the fact that silicon offers longer range, but it can be charged withing 10 minutes at higher charging rates without any dendrite formations. This combination is the key. Because apart from the major challenge of sourcing sustainable electricity without damaging grid stability, the other problems that EV faces are small range and long refueling time. By achieving this combinations, silicon batteries can replicate the IC engine vehicle's range and refueling experience. Silicon batteries may not be the only future but they sure are here to stay and grow while benefiting EV industry.

I am very very, very confident that we are going to solve the battery issue. This is like the pioneering years of racing auto racing. Where give these engineers a challenge, and somebody is going to figure out some thing that’s going to beat. I am also very, very confident that battery fires are going to become a thing.

What funny is many of battery technology is not new, but already developed and tested long time before, but since almost every industry including battery industry were so protective and afraid to lost profits from reduced demand if the new battery is sk durable, many of this tech were buried in secrecy. But since the push of EV more durable battery is what necessary we just began to rediscover it.

Dudes and dudettes of the USA network..if ya cannot make a comprehensible, interesting story about mercedes prestige lowering (in fact true, ish) and troubles..why on earth would you even assume ya self smart enough to present truths about baterries? Even 11 yrs old kids know this is a smoke currtain type product. Luring clip makers into saying when on fire just dip the car in a container of water (right. How?) .. one laptop goes a day, another 2 hours..only aa batteries in walkmen in 1992, vi a vannessa huxtable, showed a minor dip in the dontbelieveawordtheysay-image. And as a yank should know, advertising in the sixties photobook showed this stuff already. It ages old, as a concept. Battery is not a product that can be promoted, but even more so it can never be explained by laymen. Cause you have no clue, simple as that. Neither do i, neither do i (only i dont deny taht)

Super exciting! A 50% jump in energy density at the same cost or lower would be huge! Then we are getting closer to EVs at sensible prices (and thereby a complete conversion away from fossil fuel cars) and electric flight longer than short jumps.
