Korean researchers build all-solid battery prototype with 235.13 Wh/L energy density
Researchers at South Korea's Dongguk University have developed an anode-free all-solid-state thin-film battery featuring an ultrathin tin/carbon interlayer to improve lithium deposition and cycling stability. The 2.77-micrometer-thick prototype achieved a volumetric energy density of 235.13 Wh/L after 100 cycles, potentially paving the way for more reliable solid-state batteries.

Lithium-ion bankability may be holding back long-duration storage
Financing and market structures favor established lithium-ion battery energy storage systems (BESS), potentially limiting investment in alternative technologies better suited to storing electricity for eight hours or longer, according to analysts discussing US procurement and grid planning.
Stationary, moving, flexible: Batteries are the low-cost backbone of the future energy system
While it is known that batteries are indispensable for the future energy system dominated by solar PV, they are still seen as a bottleneck technology mostly related to raw material supply. Sodium-ion batteries can resolve this issue. Batteries are more than a stationary storage technology, also with bright prospects for vehicle-to-grid (V2G) and smart charging of electric vehicles within a broad flexibility technology portfolio.
German startup offers AI platform to accelerate battery storage engineering
German startup Morreon has developed an AI-based platform to streamline engineering, design optimization, tendering, and project scheduling for battery storage and other energy infrastructure projects. The system automates data processing and layout planning while maintaining human oversight, with further integration of cost calculations and construction management planned.

Wireless bipolar electrodes raise zinc-air battery power by 80%, may apply to other chemistries too
Researchers in Spain and Argentina have developed a zinc-air battery architecture that increases power output by up to 80% by reducing internal resistance without changing the device’s core chemistry.
Indian startup claims over 1,500 cycles for sodium-ion cell with Prussian white cathode
Indian startup Macsen Energy claims its Prussian white-based sodium-ion battery cell has exceeded 1,500 charge-discharge cycles in laboratory testing, retaining 90% of its initial capacity after 1,000 cycles. The company also plans to build a cathode material production facility and battery cell pilot line, with construction set to begin in 2027.
