The iPhone Air features a groundbreaking battery design using patented metal can technology, allowing for a two-dimensional shape that maximizes space and durability. This innovation not only enhances the device's form factor but also paves the way for higher energy density batteries, including the potential adoption of silicon anodes, which could significantly improve battery performance in future electronics.
A breakthrough in battery technology, involving silicon anodes with a new binder material, could extend electric vehicle range to over 3,000 miles and significantly impact renewable energy storage, advancing the shift towards greener transportation and energy solutions.
Sila, a company specializing in silicon anode battery technology, has signed a supply deal with Panasonic to provide its Titan Silicon anode material. The breakthrough battery material promises double-digit-percent increases in lithium-ion cell energy density. The higher performance cells containing Titan Silicon will initially be used in luxury vehicles like Mercedes' electric G-Class SUV, with the potential for lower prices at the battery pack level in the future.
Researchers at Rice University have developed a scalable method to enhance the lifespan of lithium-ion batteries by up to 44% using prelithiation, a process that coats silicon anodes with stabilized lithium metal particles (SLMPs). The study found that spray-coating the anodes with a mixture of the particles and a surfactant improved battery life by 22% to 44%. However, a larger amount of the particle coating led to more lithium trapping, causing the battery to fade more rapidly in subsequent cycles. The prelithiation method improves the stability of the solid-electrolyte interphase (SEI) layer, reducing the depletion of lithium ions and resulting in a longer cycle life for the battery.
Some Ford and Stellantis EV models will still be eligible for federal tax credits, despite the new battery sourcing rules that take effect on April 18. Ford's F-150 Lightning and Lincoln Aviator Grand Touring will still qualify for a $7,500 credit, while other models will see credits drop to $3,750. Stellantis' Chrysler Pacifica plug-in electric hybrid will qualify for $7,500 tax credits, while the Jeep Grand Cherokee 4xe and Jeep Wrangler 4xe qualify for just $3,750. Silicon Valley-based company Sila has finalized a mass manufacturing process for the first silicon-based anodes, which will immediately boost maximum vehicle ranges by 20 percent. Analysts doubt that synthetic fuels will ever make a meaningful contribution to the industry achieving carbon neutrality.
