Storing renewables with firebrick thermal batteries
Electrified Thermal Solutions is developing a firebrick-based thermal battery that converts low-cost electricity into high-temperature heat for energy-intensive industries. The technology could pair with solar and wind to absorb surplus generation and deliver round-the-clock industrial heat at costs competitive with natural gas.

Researchers develop tri-layer electrolyte for lithium-metal batteries
Researchers have developed a PEO-based composite solid electrolyte that combines polydopamine-coated LLZO with a flexible triblock copolymer. The optimized design reached an ionic conductivity of 5.60 × 10−3 S.cm−1 at 60 C and enabled LiFePO4|Li cells to retain 80% of their capacity after 1,000 cycles.

Scandium doping, coating improve cycling stability of sodium-ion battery cathodes
Researchers have compared bulk scandium doping and surface scandium coating in O3-Na[Ni₁/₂Mn₁/₂]O₂ cathodes for sodium-ion batteries. Both approaches improved cycling stability, with the coated full cell retaining 91.2% of its initial capacity after 300 cycles, while structural analyses revealed distinct bulk- and surface-stabilization mechanisms.
Stackelberg game framework optimizes distributed energy storage allocation
Researchers have developed a game-theory-based method for optimizing the location, capacity and operation of distributed energy storage. Simulations on a 33-node distribution network reportedly reduced load fluctuations from 25.98% to 14.25% while requiring around 85% less storage capacity than conventional methods.
Researchers develop framework for national battery storage planning
Researchers have developed an optimization framework that identifies the optimal locations and capacities of grid-scale battery storage across national transmission networks. Demonstrated on the Czech Republic's projected 2030 power system, the approach reduced electricity generation costs by up to 30%.
