Cornell University scientists created a process called Direct Electrode-to-Electrode Regeneration (DEER) that revives worn EV battery electrodes by chemically stripping excess solid electrolyte interphase buildup rather than shredding cells into raw materials. Treated electrodes recovered up to 95% of original capacity and degraded more slowly than untreated batteries, and a second treatment round restored capacity to 90% even after prior regeneration.

Startup Resilience Energy is installing solar panels and battery systems at no cost to homeowners, then aggregating that distributed capacity to sell electricity back to the grid during periods of peak demand. The approach sidesteps the years-long permitting and interconnection delays that typically slow construction of utility-scale solar farms.

Laptops with trackpads that bulge or pop out are often showing a symptom of a swollen lithium-ion battery, which sits directly beneath the trackpad in most designs including MacBooks and Surface devices. Battery swelling happens when overcharging or physical damage triggers chemical reactions that release gas, pushing outward against internal components. Apple has previously run replacement programs for MacBooks affected by this exact issue.

US energy storage set another quarterly record, powered largely by seven new gigascale battery installations exceeding one gigawatt-hour each, according to a report from Benchmark Mineral Intelligence and the Solar Energy Industries Association. Behind-the-meter batteries also grew, with data centers accounting for roughly three-quarters of new commercial installations, even as residential battery installations are projected to fall 16% in 2026 after a supporting tax credit expired in 2025.

A study by Austrian battery-analysis firm Aviloo, based on over 500,000 tests across 20 popular EV models including Tesla's Model Y and Volkswagen's ID.4, found median battery health ranging from 87 to 94 percent after 150,000 kilometers of use. The research found degradation levels between 91-97 percent at 50,000km and 88-95 percent at 100,000km, though rates varied widely depending on climate, battery size and driving habits.

Samsung's Galaxy S26 series arrived with higher prices and only incremental hardware upgrades, keeping the same 5,000mAh battery used since 2020 even as Chinese rivals like HONOR ship phones with far larger silicon-carbon batteries. New sales figures show Samsung's flagship and foldable lines are still selling well despite these limited improvements, suggesting the company has little financial incentive to push harder on hardware.

HTC has launched its Vive Eagle AI glasses globally at $499, offering a camera and audio experience similar to Meta's Ray-Ban glasses but with a key difference: a $49 magnetic Power Boost battery pack that snaps onto the frame to extend usage without removing the glasses. The built-in battery lasts four to five hours, and the add-on pack allows continuous use, unlike Meta's design, which requires placing the glasses in a case to recharge.

A clean-energy development is being built on 500 acres of a West Virginia strip mine that was abandoned two decades ago, combining solar power generation with both lithium-ion and zinc battery storage systems. Google is supporting the project, which aims to extend the availability of renewable electricity further into nighttime hours than conventional battery setups typically allow.

A technical review examines the ferrocyanide/ferricyanide redox couple, prized in flow batteries for its stability, kinetics and solubility, and asks why no one has built a symmetric flow battery using it on both electrodes. The piece explains that ferrocyanide reacts with heavy metal cations like zinc or iron to form insoluble Prussian blue compounds, blocking the metal-plating side of such a design, and notes that even chelation workarounds using pyrophosphates lead to poor long-term cycling stability, as shown by degradation data after 100 cycles.

EcoFlow unveiled new in-home battery systems in London timed with the UK's move to legalize plug-in solar setups. The author argues that standalone plug-in solar has been largely overtaken by hybrid battery-solar systems, since solar generation peaks at midday while most household energy demand happens in the morning and evening.
