Energy Density Lion batteries feature higher density of energy than other types, which means you can enjoy higher capacity irrespective of the size. That is why these batteries are an ideal choice for power-hungry devices like smartphones and laptops. With the advancements in technology, we will have higher capacities down the road.
Self-discharge Another great characteristic of a Li-ion battery is that it has only 1.5% self-discharge rate per month, which means that it offers longer-shelf life. The reason is that its discharge rate is lower than most of other rechargeable batteries. Here it’s important to note that the self-discharge rate of a nickel-metal hydride is 20% per month.
