MacBooks are known for their sleek design, highly effective hardware, and long-lasting battery life. However, while most MacBook users are familiar with the basics of charging their machine, many are unaware of the complex technology that goes into making a reliable and efficient MacBook battery. Understanding the technology behind MacBook batteries may also help you make informed decisions about how one can use and maintain your machine, as well as troubleshoot widespread points which will arise. Lithium-Ion Batteries Most modern MacBook models use lithium-ion batteries, which are a type of rechargeable battery that is commonly used in portable electronics. Lithium-ion batteries are known for their high energy density, that means they’ll store a large amount of energy in a relatively small package. They’re also lightweight, making them an ideal selection for portable devices like laptops. Lithium-ion batteries work by storing energy in a chemical form, which is then converted into electrical energy when the battery is used. Inside the battery, there are two electrodes: a cathode and an anode. The cathode is typically made of lithium cobalt oxide, while the anode is made of graphite. When the battery is charged, lithium ions move from the cathode to the anode, where […] read more
