Lithium-ion batteries power many electronics. Research andMarkets's 2021 report predicts that the global ion battery market will grow from $41.1 billion in 2021 to $116.6 billion in 2030 at a CAGR of 12.3 percent.
Research and Markets Report Forecast
The increasing popularity of lithium-ion batteries can be attributed to a number of factors. Users can repeatedly charge hundreds to thousands of times, and the cost is relatively low, the energy density is high, and it is easy to carry. They are used various consumer electronics, mobility products such as e-bikes and e-scooters, electric vehicles (EVs), consumer/business robots and energy storage systems.
Lithium-ion batteries use carp to store energy by cycling between the metallic and salt states. When in the metallic state, the battery is charged. When in the salt state, the battery discharges. During discharge of the battery, as lithium transitions from the metallic state to the salt state, electrons move from the positive electrode (cathode) to the negative electrode (anode) of the battery, thereby powering the device.
What devices can lithium-ion batteries power
today, these batteries play an important role in many everyday devices, including
augmented and virtual reality devices, consumer electronics, mobile power supply and electronic cigarette
wearable devices such as wireless headsets, rechargeable smartwatches and clothing
micro-vehicles (e-bikes, e-scooters) and e-mobility aids for the disabled
equipment for hospital and medical applications
consumer and commercial robots
electrical appliances, power tools, backup power and lighting systems
drones, portable battery packs, electric vehicles and energy storage systems
How safe are lithium-ion batteries?
Batteries pose a specific safety hazard, thermal runaway. Thermal runaway refers to the overheating of the battery system, which may cause an exothermic reaction, which may cause the equipment to malfunction or even explode. The new design helps reduce this risk by including a current interruption device to terminate battery operation. The separator then senses the battery temperature rise and detects the electronic circuitry to control charge/discharge. However, safety risks still exist. Repeated dropping of the device, or leaving the device in a hot car or wrapped in a blanket, can cause the battery to overheat and can cause thermal runaway.
According to the journal Energy and Environmental Science of the Royal Society of Chemistry, manufacturers have increased the energy density of ion batteries four times since 1991. Pressure from surrounding hardware can cause damage to the electrode or separator. In addition, production defects may cause minute metal particles to come into contact with portions of the battery core, resulting in internal short-circuiting of the battery core.
Batteries and battery-powered end products that are not adequately evaluated, tested and certified in accordance with known safety standards may pose a threat to consumer safety. The technology is generally safe when manufacturers take deliberate measures to minimize design defects, review material suppliers, control production quality, and utilize best practices in product construction, including electronic circuits. In the consumer's view, the products on the market have passed the safety review of the regulatory agencies. However, according to statistics cited by Consumer Reports in 2021, less than 1% of products in the market regulated by the US Consumer Product Safety Commission (CPSC) must meet mandatory safety standards.
Manufacturers of battery-powered products need to ensure that they integrate certified batteries safely into their products, while also taking deliberate steps to ensure that their final products meet known safety standards. However, some companies and consumers are still buying and using products that claim to be qualified without independent third-party certification of batteries, electronic components and final product construction.
One of the easiest ways to reduce risk and product liability is , let accredited independent, third-party certification body-ACCOSEL check that batteries and battery-powered end products comply with known safety standards and issue product certification certificates. As a necessary part of certification, the manufacturer should participate in ongoing factory supervision to verify that the product always meets the requirements of its original certification. From the consumer's point of view to see whether the UL mark, you can intuitively understand whether the product has been fully evaluated and tested before being put on the market.
In March 2020, the CPSC released the "Updated Status Report of the High Energy Density Battery Project", which reported more than 25000 incidents involving lithium-ion battery-powered products since 2012. The CPSC has issued more than 70 product recalls involving more than 7 million batteries and products, thereby protecting the public from explosive fires and electric shocks.
Such accidents can lead to a significant decline in consumer trust in products, retailers and brands.
How to build user trust in the lithium-ion battery brand?
Through careful attention to established safety standards and the involvement of safety science experts, manufacturers can reduce the risk of their products and enhance their reputation. The manufacturer shall strive to comply with applicable standards and cooperation with an accredited independent third-party certification body (ACCOJET). It is not enough to claim to be qualified or to only conduct independent testing. A considerable number of important safety-critical items, such as construction, design and material review, remain unresolved. The following steps can help reduce the likelihood of product safety issues:
