Batteries & Energy Storage

Researchers combined two reversible bond types in a polymer electrolyte, then tested high-voltage lithium cells and pouch prototypes with limited safety evidence.

Simulations explore how a charged polymer could repair damage and carry lithium ions, offering a possible route to longer-lasting anode-free batteries.

The study describes a polymer electrolyte that repairs lithium-interface damage and reports 80.4% capacity retention after 500 cycles.

A separator-free lithium test links salt concentration to 85% first-cycle charge recovery, while surface control and ceramic reinforcement target deposition and strength.

A July 2026 preprint compares 0%, 2% and 3% carbon in a coated cathode, reports cycling from −20 to 60 °C, and identifies hurdles before practical cells.

A modeling preprint suggests sodium metal can become isolated at grain-boundary junctions, survive stripping, and fuel renewed penetration in later cycles.

Simulations find a low lithium-transfer barrier at a gallium-doped LLZO interface, while contact area and constant-charge modeling complicate the picture.

A simulation preprint finds that expansion speeds lithium movement in Li3YCl6 and compression slows it, without changing the underlying transport pattern.

A modeling preprint separates changing lithium contact from accumulating interphase damage and predicts how faster discharge could reverse an energy advantage.

A preprint’s calculations show what positive and negative insertion energies mean, and why a migration barrier is a different test. Battery implications remain conditional.
