How to get the most out of lithium ion batteries: ( Getty) Charge away: lithium batteries don't have 'memory' problemsīack in the day, we all dutifully let our phones and seven-kilogram laptops go totally flat before recharging to avoid the dreaded battery 'memory' problem - where batteries held less and less charge over time if you recharged them before they were fully flat. During charging, the process is reversed and lithium ions are transferred back to the anode. When in use, lithium-ions (Li+, blue) travel from the negative electrode (anode) to the positive (cathode). The battery consists of a positive electrode (green) and a negative electrode (red), with a layer (yellow) separating them. The positive ions (Li + in lithium ion batteries) recombine with electrons at the surface of the negative electrode, ready to start all over again when the battery is connected to a circuit.Ī typical lithium-ion rechargeable battery. Those reactions allow positively charged ions to move from one electrode to the other inside the battery, and negative electrons to move through the wires in the circuit, producing a current.īut with rechargeable batteries, plugging your charger into an external power source forces these chemical reactions to happen in reverse. Rechargeable batteries power devices the same way that disposable batteries do - by chemical reactions at the positive and negative electrodes. And with electric cars and the new solar storage systems using lithium ion batteries too, the technology will be around for a while.Īnd the high energy for its size and weight (energy density) isn't the only benefit that lithium batteries offer. Smart phones, tablets and new laptops all use lithium ion batteries. At number three in the periodic table, it's the lightest metal, which really helps it store more energy for the same weight and volume. Lithium owes its market dominance to being a lightweight. Lithium ion batteriesĪ decade ago nicad (nickel cadmium) and nickel-metal hydride rechargeable batteries were pretty common in phones and laptops, but with the push for more energy in lighter, smaller mobile units, lithium ion batteries took over. With solar battery storage and electric cars set to take off, it's time to sort the battery fact from fiction. Rechargeable batteries already power our phones, laptops and toothbrushes. Should you let your phone go completely flat before recharging? Why do lithium batteries explode? And aren't they bad for the environment?
