A new study of 1,300 used EVs found Kia’s EV6 and e-Niro have the slowest battery degradation, with most models keeping over 90% capacity. Experts say usage and climate matter more than brand, proving modern EVs last far longer than skeptics believed.

The upcoming Volvo EX60 will showcase next-gen battery technology, including prismatic cells and cell-to-body integration, delivering higher efficiency, cost savings, and improved range. With dual-chemistry options and advanced hardware, it’s Volvo’s most ambitious EV yet.

Stellantis has revealed its Intelligent Battery Integrated System (IBIS), which embeds the charger and inverter directly into the pack. The design improves efficiency by 10%, boosts output by 15%, trims weight, and shortens charging times, with production targeted for decade’s end.

Panasonic’s new anode-free batteries could boost Tesla’s Model Y range by nearly 90 miles, approaching 450 miles per charge. The lighter, cheaper design may help Tesla stay competitive as Nissan, Chevrolet, and Rivian launch next-gen EVs.

CATL launched the Shenxing Pro at IAA Munich, boasting 470 miles of range, 10-minute charging, and 600,000-mile durability. With two tailored packs and major European investments, CATL is positioning Chinese battery innovation at the forefront of the EV market.

Changan has unveiled a new EV capable of traveling 930 miles on a single charge, enabled by a 400 Wh/kg solid-state battery — more than twice the energy density of traditional lithium-ion cells. Safety, weight reduction, and fast charging are major benefits. With prototypes due by 2025 and mass production starting 2027, this breakthrough could reshape global EV competition and challenge Tesla’s dominance.

Hyundai has patented a solid-state battery breakthrough that allows copper to replace costly metals in sulfide-based cells. The innovation improves conductivity, lowers costs, and boosts durability, potentially making EVs like the Ioniq 5 more affordable and higher-performing. While patents don’t guarantee production, this advance could accelerate the path toward mass-market solid-state EVs.

The MG4 has become the first mass-produced EV with a semi-solid-state battery approved for sale in China. Featuring a 120 kW motor and an advanced manganese-based lithium-ion pack from Suzhou Qingtao Power Technology, the new variant will launch globally by the end of 2025, with pricing to be revealed in September.

Tesla batteries are engineered for long-term performance, supported by advanced thermal control, software optimization, and active battery management systems. This in-depth guide explores Tesla’s lithium-ion technology, real-world degradation data, and best practices to extend battery life. With most owners reporting 5% or less degradation after 50,000 miles, proper charging and usage habits can significantly enhance Tesla battery longevity.
