odes. By combining shredded PET with small amounts of graphene oxide and a controlled heat treatment process, the team

produced graphite with a highly ordered crystal structure while avoiding the use of metal catalysts. Although still at the laboratory stage,

the technology could provide a sustainable way to recycle plastic waste while supplying a critical battery material for the growing EV and

energy storage industries.

• This Flaw Keeps Sabotaging Solid-State Batteries. Scientists Found A Solution.- insideevs.com Researchers at MIT and the Technical

University of Munich have identified a major cause of dendrite formation—a key obstacle preventing the commercialization of solid-state

batteries. The team found that microscopic grain boundaries within solid electrolytes create electrical imbalances that encourage the

growth of lithium metal spikes, which can lead to battery short circuits and failure. By modifying the electrolyte processing method to reduce

these effects, the researchers achieved over 300% higher current density while improving battery stability and lifespan in laboratory tests.

The breakthrough could help accelerate the development of safer, faster-charging, and higher-energy-density solid-state batteries for

future EVs, although challenges related to cost and large-scale manufacturing remain.
