Rechargeable Batteries

German researchers say a new type of electric vehicle battery that runs on electrolyte fluid can be recharged as easily as refilling a petrol tank. When the redox flow rechargeable batteries are low, the discharged electrolyte fluid can simply be exchanged at the gas station for recharged fluid. Read More

Winter sports offer all manner of exhilarating and exhausting possibilities - from negotiating seriously difficult trails, to mountain trekking or adrenaline-producing snowmobiling. But what if your boots aren’t up to the job, and you have to confess to your fellow hikers that you can’t go on because your feet are too cold? Enter Columbia’s Bugaboot Thermo Hiking Boots - the first hiking boots to integrate a three-temperature heating system to provide protection from the cold…and scornful looks from your hiking buddies.

The new line of THINERGY Micro-Energy Cells from Infinite Power Solutions Inc (IPS) could soon be powering small devices such as autonomous wireless sensors, powered smart cards, active RFID applications, and implantable medical devices. The manufacturer says these tiny, rechargeable, thin-film batteries combine the energy density of traditional batteries with the high discharge current of supercapacitors. With some models measuring just 0.5 inches square (12.7mm) and less than 0.01 inches thick (0.17mm), IPS claims these are the most powerful batteries for their size. Read More

A Canadian research team led by Dr. Linda Nazar has synthesized a prototype of a lithium-sulphur rechargeable battery that, thanks to its peculiar nanoscale structure, can store three times the power of a conventional lithium-ion battery in the same volume while being significantly lighter and potentially cheaper to manufacture.
