Brace Yourself For the Next Generation of Smartphone Batteries( Report)

Nowadays, if you need a smartphone with a high capacity battery, you have to compromise with the size of your smartphone. Battery size has to be increased in order to increase its charging capacity, it is ineluctable. Also, with greater battery size comes greater battery weight. Overall, you cannot choose a light weight battery with better performance or a better performing battery with lesser size, or vice versa. We all have learnt to live with this limitation, as chemistry is to be blamed here for the issue.

For example, lithium-ion batteries which we commonly use in our smartphones have limited capacity to absorb and retain charge. To increase the charge, we need to increase the size of the electrodes as it is the only available solution. However, increase in the electrode size obviously results in increase in battery size and battery weight. To overcome this, one of the viable solution is to switch to some better materials than lithium-ions that can provide higher charge retention with same battery size.
