(This depends on how well you take care of your battery, and the amount of use it gets). The chemical reactions in rechargeable batteries can happen hundreds of times, and in both directions, which can typically give you anywhere between 2 – 10 years of battery life. When the battery is being used, the reactions go out one way releasing power, when the battery is absorbing power, the reactions move in the opposite direction. The main difference: rechargeable batteries use chemical reactions that are reversible. Rechargeable batteries use different chemicals that split apart in different ways than normal batteries. Reversible Reactions = Rechargeable Batteries This is the main reason why you can’t recharge your typical AA battery. The only problem with batteries like this, is that there is one single reaction and they can only run in a single direction. This provides electrical energy, causing your flashlight to light up. Ions move through batteries, and electrons move through circuits to which the battery is connected. The chemicals inside of the batteries will systematically split apart and join themselves with other chemicals, which produces Ions (Positively charged Particles) and electrons (Negatively Charged Particles). If you connect the two ends of a battery to a flashlight, then chemical reactions start happening. If you don’t know much about batteries, then I can tell you that they are basically canisters harboring chemical experiments. This is all very interesting stuff, but how do they work? Let’s take a closer look below. Lithium Ion batteries have been widespread since the early 90’s, but the chemistry of these batteries were invented by Gilbert Lewis, an American chemist (1875 – 1946), in 1912. The rechargeable batteries can definitely make a difference, and the best rechargeable batteries use a technology known as Lithium Ion.Ĭhances are, your laptop, your cellphone, or even your music playing device are using lithium ion. Believe it or not, we throw away billions of batteries every year worldwide. The only problem is, most batteries tend to run flat very fast, unless you have a special charger, then they become garbage. Your wallet, and the environment both take a beating. Batteries give us the convenience of electricity, in a small portable handy form. Batteries are our power-to-go, or at least that’s the promise that they deliver.
