Battery Technology on the Rise With 24V Rechargeable Li-ion Batteries
Your rechargeable batteries dont offer the energy densities you need to charge your electronic devices, so maybe you need a lithium-ion battery. Lithium-ion batteries can power devices for long periods of time without losing their maximum energy capacity over successive recharges. They work using lithium ions that move between the negative electrode and the positive electrode during discharge, before moving from the positive to negative electrode during recharge.
What Are the Advantages of 24V Lithium-Ion Batteries?
Li-ion batteries have high energy density properties and relatively low self-discharge when compared with nickel-based batteries.
- Li-ion batteries have an energy density roughly twice that of standard nickel-cadmium batteries and will keep your electronic equipment powered for longer between recharges.
- These rechargeable batteries have a low self-discharge, which means they don’t lose their maximum energy capacity if repeatedly recharged after only partial discharge.
- Li-ions don’t need priming when theyre new like some rechargeable batteries, and don’t require any maintenance, such as periodic discharges, like NiCd cells.
What Should You Consider When Buying a Lithium-Ion Battery?
One of the main advantages of lithium-ion rechargeable batteries is that they come in a variety of types, which means you can find the right technology for your particular application. You can divide Li-ion battery formats into four main groups—small cylindrical, large cylindrical, pouch, and prismatic—so its important that you check the requirements of your electronic device before buying.
- Because some lithium-ion rechargeables offer a high current density, they’re ideal for mobile electronic equipment, such as mobile phones, laptops, and digital cameras. Other Li-ion rechargeables can provide higher current levels, which makes them a good option for power tools and electric vehicles.
- Check the rechargeable battery life before purchase. This is usually the number of full charge-discharge cycles before a noticeable capacity loss.
- While lithium-ion batteries have a high energy density and low self-discharge, they do require a protection circuit to maintain safe operation. This limits the peak voltage of each cell during charge and stops the voltage of the cell from dropping too low on discharge.
How Long Can You Expect Lithium-Ion Batteries to Last?
Keep in mind that lithium-ion batteries will age and some capacity deterioration will be noticeable after a year, even if the battery has not been in use. Store your battery in a cool place to slow the aging process and keep it partially charged during storage.
- Battery performance is rarely specified as being for more than 500 cycles, although on average, it can be around 1,000 cycles. This means that a Li-ion battery charging your mobile phone is not expected to work without a significant capacity loss for more than three years.
- Lithium-ion battery technology is constantly improving with new chemical combinations resulting in less aging.
