Researchers led by Professor Dennis Leung from the Department of Mechanical Engineering at the University of Hong Kong (HKU) has discovered a new possibility—a rechargeable aqueous battery with a magnesium metal anode. The innovation opens a new direction for the development of post-lithium-ion batteries. “With a high theoretical capacity and negative electrochemical potential, magnesium is …
Advanced materials technology company, Sylvatex (SVX), announced a new proprietary waterless production method that delivers premium EV-grade cathode active materials (CAM) at lower costs and that allows for a broader material input supply base to enable demand growth. They expect this simpler and more sustainable approach to CAM production can enable a 25% reduction in …
Demand for lithium-ion batteries is set to grow six-fold by 2032, according to Benchmark. Accordingly, the world needs more than 300 new mines to be built by 2035 if raw material supply is to keep up with this demand, according to a new analysis by Benchmark. However, recycling could help reduce the number of mines …
The global capacity of lithium-ion battery gigafactories is set to surpass seven terawatt hours (TWh) by 2031, according to Benchmark’s Gigafactory Assessment. This milestone comes just four months after the ten-year pipeline exceeded six TWh in April. Over half of the global capacity is 2031 is controlled by just nine companies. China is set to …
Assuming each EV travels 12,000 miles annually, consuming approximately 300 Wh/mi of AC energy and assuming 4.9 % system losses for transmission and distribution, then each EV will require 3.8 MWh/year of energy generation. If there were 10 million EVs in California then they would need 28 TWh/year. The US has added up to 100 …
Energy Parks on Twitter was trying to push unsubstantiated fears of battery fires in response to my coverage of my positive experience with Tesla solar power and Powerwall batteries. My positive experience is that I have ample solar power to run my air conditioning in recent hot weather 95-117F (35-47C). I sell power back to …
A heat wave will last until the end of this week in the San Francisco Bay Area. Temperatures 100F (38C) or so all week. Today is the fourth day out of the last five days with a Virtual Power Plant event. Tesla has created the software so that the utility PGE (Pacific Gas Electric) can …
BYD is aiming for 280,000 monthly deliveries of battery electric (BEV) and hybrid electric cars (PHEV) by the end of the year. BYD sold and delivered 174,915 hybrids and BEV in August. In August, BYD had 82,678 BEVs which was nearly triple the 30,382 units in the same month in 2021. Plug-in hybrid vehicles were …
Today will be the fourth Tesla-PGE Virtual Power Plant (VPP) event in 17 days. VPP today. This will be for about 2 hours. A solar power blog reported that earlier Tesla-PFE were targeting or estimating 20-60 hours per year. The VPP only operates from May to October. 60 days at 10 hours every 20 days …
This is the third PGE Virtual Power plant day in 15 days. I am in the VPP program in Northern California. This is the second day in a row with a VPP and the third since the first 15 days ago. Tesla set up the software to allow people with stationary storage power walls and …
Tesla 4680 structural packs has eliminated threaded fasteners which is the cause of 75% of failures in cars. Sandy Munro believe there are 816 or 828 battery cells in the pack. There is four sections of 204 battery cells (6X34) but there could be a section with 12 extra cells hidden under the foam. They …
