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.
The new program confirms which home battery products have been tested against the industry’s best practice guidelines… Products that qualify for the Battery Assurance Program … have been independently tested to confirm they are up to the necessary electrical safety and quality standards.
Dr Quach says that unlike ordinary batteries, which take the same amount of time to charge no matter how many you have, the theory is that quantum batteries would charge faster the more you have of them.
“If one quantum battery takes one hour to charge, then two would take 30 minutes, three would take 20 minutes, and so on. If you had 10,000 batteries, they would all charge in less than a second,” he said.
“The guide provides minimum electrical safety criteria that could be applied to lithium-based battery energy storage equipment and is the result of extensive collaboration from system manufacturers, certifiers, safety regulators and industry bodies around Australia.”
“The Guide is voluntary for use by anyone in the supply chain of battery storage equipment. It is not referred to in any legislation as a mandatory requirement however, both electrical safety legislation and Australian Consumer Law requires electrical equipment to be safe and fit for purpose.”
“In January 2018, in cooperation with various government regulatory agencies, HP announced a worldwide voluntary safety recall and replacement program for certain notebook computer and mobile workstation batteries. These batteries have the potential to overheat, posing a fire and burn hazard to customers. For this reason, it is extremely important to check whether your battery is affected.”
“HP has received eight reports of battery packs overheating, melting, or charring, including three reports of property damage totaling $4,500, with one report of a minor injury involving a first-degree burn to the hand,” CSPC said in a statement
What are the hazards?
Small parts, including the battery can be exposed if the back is removed. If young children gain access to the button batteries and ingest them, they may suffer internal burn injuries, which can result in serious illness and even death. In addition, the batteries may pose a choking hazard to young children.
The electronic skin contains about 50 components connected by a network of 250 tiny wire coils embedded in protective silicone. The soft material enables it to conform to body, unlike other hard monitors. It wirelessly transmits data on movement and respiration, as well as electrical activity in the heart, muscles, eyes and brain to a smartphone application.
The entire system is powered wirelessly rather than being charged by a battery.
