At CES 2026, many of the new devices no longer fit neatly into existing categories. From GPS-enabled electric golf push carts, to “smart mirrors” that can estimate lifespan, storytelling robots that speak fluently with children, and robotic vacuum cleaners equipped with flying arms—product concepts have clearly moved into a more fluid and experimental phase.
You can now charge your devices much faster. This is because of new lithium-ion battery technology. Engineers use special lithium compounds and high-density cells. These help ions move quickly and safely. New voltage adjustment methods let batteries take in more power.
You must watch the maximum voltage when using a lithium-ion battery. This number is usually 4.2V. It is the highest voltage the battery can safely reach when charging. The battery’s materials and electrode potential set this limit.
