If you replace the battery in the newest iPhones, a message indicating you need to service your battery appears in Settings > Battery, next to Battery Health. The “Service” message is normally an indication that the battery is degraded and needs to be replaced
Recycling rates of lithium-ion batteries are higher than some people think, about 50% versus reports of rates as low as 5%, according to Hans Melin, founder of Circular Energy Storage Research and Consulting. Still, not all materials in the batteries, including lithium, are reprocessed and end up in new products. S&P Global Market Intelligence recently caught up with Melin to talk about the complex life cycle of a lithium-ion battery. The following conversation has been edited for length and clarity.
Lithium-ion batteries are more expensive than similar capacity NiMH or NiCd batteries. This is because they are much more complex to manufacture. Li-ion batteries actually include special circuitry to protect the battery from damage due to overcharging or undercharging.
Lithium is relatively rare and rather difficult to process for use in batteries. Sodium is abundant and easy to work with. There are chemical similarities between the two elements that suggest sodium-ion batteries could be a low cost — and environmentally friendly — alternative to lithium ion batteries.
Wirelessly charging your phone, while highly convenient, risks depleting the life of devices using typical lithium-ion batteries (LIBs), report researchers.
