As we know, Lithium-ion batteries are the ones which are still considered the best and are used in our mobile phones and other devices for many years. But can you imagine a battery which gets charged completely within a minute? Stanford University has developed a new type of Aluminium Ion battery that gets charged fully in one minute and does not catch fire, even if we drill through it. Unlike earlier aluminium batteries, which generally fail after only about 100 recharge cycles, Stanford's prototype can cycle more than 7,500 times without any capacity loss - 7.5 times longer than your average lithium-ion. It is used in everything right from smart watches to passenger jets. It appears to be a really leading step in reaching a greater elevation towards technology, but the thing is that the aluminium-ion cell isn't perfect (yet) as it can only produce about 2 volts, far less than the lithium which can produce 3.6 volts; plus aluminium cells can only carry 40 watts of electricity per kilogram compared to lithium's 100 to 206 W/kg power density. But it has been said by great scholars and researchers that "Improving the cathode material could eventually increase the voltage and energy density." Apart from these issues, aluminium-ion battery appears to be the best with the most welcoming features such as inexpensive electrodes, good safety, high-speed charging, flexibility and long cycle life when compared to lithium-ion battery. The best thing, it costs a fraction of what Lithium-ion does!
