Future trends in the battery industry

There are unexpected parallels between diamonds and batteries. Diamond is formed under extremely high pressure and is the world's most valuable gemstone. Likewise, battery technology is developing under increased pressure from end users and manufacturers, while remaining one of the most valuable components in electronic devices.

Three top trends are shaping the way that batteries are being developed. Safety concerns are leading battery manufacturers to re-think their active materials and cell construction techniques. The increase in wearable devices is driving the trend for batteries with increased power density and the growing battery grey market is making battery manufacturers conscious of end-user safety.

Safety concerns

Recent battery scandals have caused concern about the safety of Li-ion batteries. The Federal Aviation Administration (FAA) recently restricted certain smartphones on their flights, which were at risk of exploding. Design flaws in the battery caused the separator between the positive and negative tabs to breakdown. This meant that the battery short-circuited, overheated and in some cases caught fire.

Following this controversy, researchers at Stanford University suggested a way to introduce flame retardant material into Li-ion batteries to prevent fires caused by overheating.

Electronic device Original Equipment Manufacturers (OEMs) need to ensure that the batteries they are purchasing meet the latest international standards for safety and performance – this means checking that requirements are met both at a cell and a battery level. Suppliers of batteries should work under strict design control because a seemingly trivial design change can have damaging consequences further down the supply chain, if the change has not been properly validated.  

Wearable devices

The Consumer Electronics Show (CES) saw an abundance of wearable health and fitness devices. From sleep tracking headphones to an infrared thermometer with a smartphone app, the wearable device market is continuing to grow. As a consequence, battery manufacturers now face the challenge of making smaller batteries that deliver longer runtimes.

To meet this demand, scientists have recently created what has been dubbed the bendy battery, a flexible battery containing aluminium and graphite foam, surrounded by liquid salt. The battery has attracted a lot of interest from manufacturers for its lightweight design and potential for use in powering flexible displays. However, there is still a long way to go, as the bendy battery currently only delivers half the voltage of a lithium-ion battery.

The grey market

The use of batteries for life-critical devices, whether in the medical or military sector, means there are increasing safety and security concerns. This is combined with the global rise in counterfeiting and the battery grey market, with imports of counterfeit goods accounting for almost 2.5 per cent of global imports.

Counterfeit batteries pose a risk of overheating or catching fire, as well as not delivering a reliable performance. To counter this, Accutronics’ smart batteries feature algorithmic security, meaning that if a counterfeit battery is inserted into the host device, it can display a warning message or shut down completely. Counterfeit batteries often look identical to branded batteries, so OEMs must look for security features such as this to protect their devices from battery counterfeiting.

The demand for more energy dense yet smaller batteries means that the battery market is looking for ways to stay ahead of the needs of device OEMs. Also shaped by concerns over counterfeiting and the grey market, battery manufacturers are looking to innovate sustainably and safely. It is clear that this pressure is creating a diamond of the global battery market, which is expected to be worth over $17 billion by 2021.

Cell-sized Batteries:
These microbatteries could be only half the size of a human cell. Interestingly, these would be made of viruses. This rare innovation is set to provide us a relief from heavy 9-volts batteries and other models. This technology involves the use of microcontact printing. This printing fabricates and position microbattery electrodes. Further, it is probably the first use of virus in this field. These batteries could be used in a series of fields such as computers, cell phones and medical equipments which are implantable.
 
Precise Pattern Micro-chip

Precise Pattern Micro-chip:
This innovation is supposed to bring microchip technology at its peak. This system works when some molecules are made to assemble themselves into precise patterns. A self-assembling molecular system which is called block copolymers was known for many years. This system was not very effective as it could produce a molecular-orders or patterns in a very limited way via self-assembling. Thus to make it more equipped and advanced, this "limited self-assembly" was made to combine with conventional lithographic chip-making technology. These lithographic patterns cause a tight-hold over self-assembling molecules. Thus they become more structured.
 
High-Power Solar Concentrators

High-Power Solar Concentrators:
As the initial research has proved to be fruitful, there are chances that in coming years we will see a sort of solar concentrator, which would be more efficient than the contemporary solar concentrators. The most striking part of this innovation is that it brings huge amount of solar light to the solar cells that too without tracking the sun. Though it showed only 92 percent of stability during the research, it is supposed to guarantee a 100 percent stability till it arrives in the market.
