Like I said, rechargeable lithium-ion batteries are everywhere! This is what makes getting these batteries cheap because people tend to toss old electronics that get broken or just stop working, but leave the battery inside. I usually get mine from the thrift store for pennies, or from old toys people give away or get broken and donate for science. The ones to look for are as follows: hand-held devices, cell phones, digital cameras or camcorders, portable DVD or video players, and my personal favorite, laptop batteries. There are different chemistries associated with rechargeable lithium-ion cells as well such as lithium cobalt oxide (ICR-type), lithium iron phosphate or LiFePO4, (you won't encounter these being thrown away often), lithium manganese oxide (IMR), lithium manganese nickle (INR) and lithium nickle manganese cobalt oxide (NCA or hybrid). The MOST common you will find are the ICR-type lithium cobalt oxide. It's the best for energy density and power, but has average to low discharge current and temperature threshold. The maximum discharge current for these is equal or at least double the capacity at most. Plus, they are less stable (read: dangerous) than the other types and need to have some kind of protection circuitry. Now, let's not confuse lithium-ion batteries with lithium-ion polymer batteries or LiPo batteries. In LiPo batteries the electrolyte, anode, and cathode, positive and negative terminals, are housed in polymer pouches. The internal chemistry is similar to lithium-ion cells. Depending on the device, the battery will be different in shape or size, but they are usually rectangular and thin for cell phones or compact devices, or cylindrical like (common in laptop batteries) or common in hump packs for cameras or camcorders.

In case you've ever wondered, the name of the battery contains its dimensions. "" means the battery is 18 mm in diameter and 65 mm long. The "0" is just hanging out. Regardless of the type or size, these may have a single cell, or multiple cells. Multiple cells are either in series or parallel, or a mix of both. Even small batteries can have two small cells inside connected in series or series/parallel. This is due to the fact that some devices have increased voltage needs more than a single cell can provide, or to add capacity. Series connections increase the voltage, and parallel connections increase the capacity of the pack. Unlike NiMH or NiCad batteries, lithium-ion battery packs will have some kind of protection device in them like a battery management system consisting of IC's and MOSFET's or resistors that regulate current, voltage, detect short circuits, reverse polarity, and temperature. Some have an added function of balancing the cells if there are multiple cells. Why do they need this? It's because the chemistry of the lithium cell makes it sensitive to over charging, over- discharging (draining until the voltage gets too low), short circuit, and even over temperature. Any of those can damage the cell, or worse, cause a fire. Multiple cell batteries in series need the balance function that makes sure each individual cell receives the same amount of current and voltage as the other cells. If one cell gets more charge than another one, it can wear out faster or get damaged. The capacity of the pack is also reduced. These types of batteries also require special charging procedures that NiMH or NiCad's don't. More on that later!
Welcome to the world of batteries &#; the latest and greatest in cylindrical li-ion technology. As an experienced battery expert, I&#;m excited to share with you everything you need to know about batteries, from their capacity and compatibility to their performance and safety features. Whether you&#;re a business customer looking for the best batteries for your products or a battery enthusiast eager to upgrade your flashlight or vaping device, this comprehensive guide has got you covered. So, let&#;s dive in and explore the battery revolution!
Battery Basics
As a battery enthusiast, it&#;s important to understand the basics of batteries before diving into the details. In this section, we&#;ll cover everything you need to know about batteries, from their basic definition to their compatibility with devices.
What are batteries?
batteries are cylindrical lithium-ion batteries that are 21mm in diameter and 70mm in length. They are larger than the popular batteries and have gained popularity due to their high energy density, longer run time, and increased safety.
Capacity and dimensions
The capacity of a battery can vary depending on the brand and model, but they typically range from mAh to mAh. This high capacity, combined with the larger size, makes the battery an excellent choice for devices that require a lot of power. Currently, the highest capacity of battery is mAh at the market.
Unprotected and protected types
Like other lithium-ion batteries, batteries come in both protected and unprotected versions. Unprotected batteries are simply the bare cells without any additional protection, while protected batteries have a built-in protection circuit that helps to prevent overcharging, over-discharging, and short circuits.
It&#;s important to note that unprotected batteries can be dangerous if not handled properly, so it&#;s recommended to use protected batteries in most devices. However, unprotected batteries can be useful in certain applications where maximum power output is needed.
Compatibility with devices
Many high-end devices, such as flashlights and vaping devices, are designed specifically for batteries. However, some devices may also be compatible with or other battery types. In addition, Not all batteries are created equal. Some devices may only work with certain brands or types. So be sure to check your device&#;s specifications before making a purchase.
With these basic concepts in mind, let&#;s dive deeper into the world of batteries and explore their benefits, top brands, and more.
Performance and Safety
As a battery expert, I&#;ve tested and used countless lithium-ion batteries over the years, and batteries continue to impress me with their outstanding performance. Let&#;s dive into the advantages and disadvantages of these batteries and discuss some important safety considerations.
Advantages and Disadvantages of Batteries
One of the key advantages of batteries is their larger capacity compared to other lithium-ion batteries. This means they can power devices for longer periods of time and require less frequent charging. They also have a higher discharge rate, making them suitable for high-drain devices like flashlights and electric vehicles.
However, with these advantages come some drawbacks. batteries are larger and heavier than other lithium-ion batteries, which may not be suitable for some devices. They are also more expensive, and not all battery chargers are compatible with them.
Safety Considerations
Safety should always be a top priority when working with lithium-ion batteries, and batteries are no exception. It&#;s important to use only high-quality, reputable brands and to avoid overcharging or exposing them to extreme temperatures.
Another safety consideration is the use of protected vs. unprotected batteries, as discussed earlier. If you&#;re not experienced in handling unprotected batteries, it&#;s best to stick with the protected type for added safety features.
Environmental Impact
As we strive towards more sustainable and eco-friendly practices, it&#;s important to consider the environmental impact of our battery use. While lithium-ion batteries are generally more eco-friendly than traditional disposable batteries, they still require proper disposal or recycling to prevent harmful chemicals from entering the environment. Many battery manufacturers now offer recycling programs for their products, so be sure to look into these options when it&#;s time to replace your batteries.
