Researchers have discovered the root cause of why lithium metal batteries fail, challenging a long-held belief in the field. The study presents new ways to boost battery performance and brings research a step closer to incorporating lithium anodes into rechargeable batteries.
“Fidget Spinners help people channel their nervous energy into a toy conducive to one-hand fidgeting. Think of them as the modern equivalent of a stress ball. But a model … that features LED lights has been recalled for failing to conceal its button battery securely. Infants who swallow a button battery are exposed to serious health risks, warns Product Safety Australia.”
Fidget spinners probe launched in WA after reported eye injury, battery size concerns:
“An investigation has been launched …after an 11-year-old boy in Victoria reportedly suffered a serious eye injury from one of the models. A 10-year-old girl in the United States has also reportedly swallowed a small part of one of the models.”

“He threw the spinner up a little higher,” Molly said, “and he didn’t manage to catch the spinner but it came down and clipped the corner of his eye and crunch. He was very lucky not to lose his eyesight let alone his eyeball.”
Are Fidget Spinners Bad for You? Texas Girl Has Surgery After Swallowing Metal Toy Part
A young girl aged 10 in Houston was taken “to the emergency room after the girl swallowed part of her fidget spinner. (She) had put a metal piece of her fidget spinner in her mouth to clean it, and it went down her throat. (She was taken) to the Texas Childrens Hospital, where an X-ray revealed the part—called a bushing—was stuck in her esophagus. The girl had to have surgery to “endoscopically locate and remove the object,” which was about the size of a quarter…

She had just bought her 3 year old grandson the Fidget Spinner, and he and his mother were riding with her in the car. “He was playing with it going down the road,” then the child’s mother noticed the spinner had come apart and the child had the parts in his hand, including a small battery that lights up.
What are the defects?
The battery cover can be opened without the use of a tool. This could allow young children to access the button batteries inside.
What are the hazards?
Ingestion of button cell batteries by young children can cause internal burns which may lead to serious injury or death.
Samsung tested the batteries in its recalled Galaxy Note 7 using a CTIA-certified lab owned by the electronics giant, according to The Wall Street Journal… Lithium ion batteries for cellphones sold in the United States are tested in accordance with IEEE 1725 at […]
Eddie Forouzan, a member of the IEEE committee that developed the battery standard, (said) battery safety failure rates have dropped to parts per billion from the parts-per-million level that accompanied a flood of cheap batteries that proliferated in the early 2000s
A U.S. ban on carrying Note 7 cellphones on commercial aircraft either in cabin or in checked luggage (is in effect)
The Minister for Infrastructure and Transport Darren Chester issued a reminder to airline passengers to carefully consider items in their carry-on luggage after a lithium battery in a passenger’s carry-on bag caught fire at Sydney Airport.“ On this occasion the battery caught fire while the plane was on the ground and the issue was resolved. Whilst there was no damage to the aircraft, several passengers did report feeling ill.
“The ACCC’s investigation found there are fire safety risks from defective charging devices, electrical circuitry and substandard lithium-ion batteries. “There have already been six house fires in Australia directly linked to the scooters, which has resulted in the destruction of two houses.“
The ACCC will work with state and territory electrical safety regulators to develop a longer-term solution.
