“As always, a healthy dose of skepticism is important when it comes to an alleged ‘battery breakthrough,'” Fred Lambert reports for Electrek. “Those announcements are being made every 2-3 months over the last decade and rarely anything comes to it, but at least we can always rely on the 5-8% annual incremental improvements in li-ion battery capacity.
