The Internet of Things (IoT) has proven to be one of the main drivers of innovation for many companies in the semiconductor industry today. Many products such as starter kits, microcontrollers and gateways have been developed to support the nascent IoT.

However, there are other devices and solutions developed in 2015 that are not IoT-related. Automotive and power are two sectors with some of the most innovative products announced this year. Single-board computers, headed by Raspberry Pi, also showed great improvements in terms of capacity and size.

EE Times India reviewed some of the biggest products developed by semiconductor companies in 2015 and picked 10 that made the strongest impression to our readers.

Rechargeable aluminium-air battery uses salt water

Fuji Pigment Co. Ltd has announced a novel type of aluminium-air battery that can be recharged by refilling salty or normal water. The battery has a modified structure that promises longer battery lifetime, the company stated, which is estimated at a minimum of 14 days.

Ryohei Mori invented the aluminium-air battery that uses a modified the aluminium-air battery structure by placing ceramic and carbonaceous materials between aqueous electrolyte and electrodes as an internal layer. Owing to the battery's modified structure, anode corrosion and by-product accumulation were suppressed, which resulted in longer battery lifetime.

The 0.7-0.8V aluminium-air battery, which provides 400-800mA/cell, claims to have a theoretical specific energy level of 8,100Wh/kg and has the second largest capacity among various types of potential secondary batteries. Theoretical specific energy of a commercialised lithium-ion battery is 120-200Wh/kg, which means that the aluminium-air battery possesses theoretical capacity more than 40 times as large as that of a lithium-ion battery.

Although commercialised rechargeable lithium-ion batteries are widely used in mobile phones, laptop computers and similar electronic devices, their energy density is still insufficient to permit their use in electric vehicles at an industrial level with economical cost. As of the present, the highest energy storage technologies developed by researchers are metal-air batteries. Several metal-air batteries such as lithium, iron, aluminium, magnesium and zinc-air, etc. have been investigated due to their promising energy densities. Among them, aluminium is an abundant, attractive anode material for energy storage and conversion because of its high specific capacity, highly negative standard electrode potential. In addition, aluminium is the most recycled metal in the world and is economically cheap.
