Researchers at POSTECH in South Korea have developed a tin-embedded hard carbon anode that enables lithium-ion batteries to charge in just 20 minutes while lasting over 1,500 cycles. The breakthrough overcomes previous challenges of tin’s volume expansion by dispersing tiny nanoparticles throughout a porous carbon matrix.
This anode also shows strong performance for sodium-ion batteries, suggesting applications beyond just lithium-based chemistries. This innovation marks a major step forward with EVs and stationary storage increasingly demanding faster charging and longer lifespans.
Possible business implications include fast-charging, durable batteries, which could transform electric vehicle competitiveness and reduce reliance on expensive raw materials like cobalt. Automakers and battery manufacturers adopting new anode technologies early may capture a growing market share.
