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.
Scientists at the University of Albany developed a boron-based rocket fuel compound, manganese diboride (MnB2), that offers 150% more energy than aluminum, with a spring-like structure that stores and releases energy efficiently, potentially revolutionizing space propulsion and payload capacity.
The Interior Department has issued a secretarial order restricting permits for solar and wind projects on federal lands unless they match the energy density of traditional power sources like coal, gas, or nuclear, potentially halting many renewable projects and emphasizing a focus on land use efficiency over environmental benefits.
The Galaxy S25 Edge's battery, despite its smaller capacity of 3,900mAh, actually has a higher energy density (758Wh/L) than the Galaxy S25 Ultra's 5,000mAh battery, indicating Samsung's efforts to optimize battery technology within the slim design, possibly using advanced materials like Silicon Carbon, though they opted for conventional Lithium Ion batteries for safety reasons.
Researchers have developed a novel 2D/3D/2D heterostructure that enhances the energy storage capability of ferroelectric capacitors. By controlling the relaxation time of ferroelectric materials using 2D materials, they achieved an energy density up to 19 times higher than commercially available capacitors, with an efficiency over 90%. This innovation paves the way for high-performance electronic devices, particularly in sectors requiring robust power management solutions, such as electric vehicles and infrastructure development.
Panasonic plans to produce a new version of the 2170 cells used in Tesla vehicles at its Nevada plant, aiming to quadruple production capacity by 2030 without building new factories. The improved cells with higher energy density could reduce EV prices. The company also announced plans for a new battery manufacturing plant in the US and an agreement to purchase nano-composite silicon anode material, which could enable 500-mile nonstop trips and 10-minute recharges in EVs. The Biden administration's Inflation Reduction subsidies have been beneficial for Panasonic, with the company forecasting a $587 million increase in operation during the fiscal year ending March 2024.
Apple is reportedly developing a "next generation" battery for its future vision headsets, with a potential integration into products after 2025. The battery utilizes a new cathode composition to increase energy density and charging rate, and Apple is exploring the use of silicon instead of graphite in the anode to further enhance energy density. The company may have found a solution to silicon's longevity issues and is even considering carbon nanotubes as a conductive material. The success and implementation of these innovations remain uncertain, as Apple could delay or cancel the battery project at any time.
QuantumScape, the solid-state battery developer, has made significant progress towards commercialization in the EV segment. In its Q2 2023 report, the company announced the shipment of high cathode-loading cells to automotive partners and revealed a potential launch partner for its first product. QuantumScape's prototype cells have passed safety tests and it has demonstrated a 10-80% fast charge in 15 minutes. The company also outlined plans for implementing a fast separator heat-treatment process in manufacturing. With over $900 million in liquidity, QuantumScape expects to continue development into the second half of 2025.
The upcoming iPhone 15 lineup may feature stacked battery technology, which increases energy density and prolongs the battery's lifespan. Stacked battery cells use a lamination technique that allows for more active material and higher overall capacity. This technology is already used in electric vehicles and other industries. Additionally, there are rumors of Apple exploring 40W wired charging and 20W charging via MagSafe, but the source's credibility for Apple leaks is uncertain.
Samsung is reportedly working on stacked battery technology that could improve energy density by over 10%, leading to longer-lasting batteries or smaller phone designs. The Korean brand is collaborating with two Chinese companies to develop equipment for creating stacked battery designs, which it already uses for electric cars. This new battery design could be used in phones, tablets, laptops, and other consumer electronics, but there is no timeline for commercial release yet.
Samsung is reportedly partnering with two Chinese companies to scale down batteries typically used in electric vehicles (EVs) for use in its next-gen flagship Android smartphones, potentially resulting in improved specs and increased screen-on time. The new "stacked smartphone battery" is expected to have a density of 10% or more than its predecessor.
