Is it safe to use lithium batteries for mobile phone batteries? What are the types of mobile phone lithium batteries?

Have you ever thought that if the battery didn’t exist, we would only be able to use the phone when it was plugged directly into a power source. Imagine what that would be like! But that’s thanks to rechargeable battery technology that’s been improving over the years. The improvements have been made primarily to make batteries safer, more durable, store more energy per unit of volume, and also become cheaper.

What cell phone has a lithium battery?
From the late 1990s until today, cell phones have primarily used lithium-ion batteries as their power source. In recent years, nickel-cadmium battery technology has been phased out by lithium-ion batteries due to its many advantages over other battery technologies. Lithium-ion batteries are preferred due to their high energy density, durability and portability, which are very important in mobile phone design. As of 2020, almost all smartphones and other cell phones primarily use lithium-ion batteries.

What type of battery does the phone use?
There are two main lithium battery technologies used in mobile phones today: lithium polymer batteries and lithium ion batteries. The main difference between the two is that Li-polymer batteries use a polymer electrolyte instead of the liquid electrolyte used in Li-ion batteries.

Lithium-polymer batteries are a new technology in lithium-ion batteries, and because they have many advantages over lithium-ion batteries, they are also more expensive. Let us see some of the benefits;

  1. They have a higher energy density than lithium batteries. This means that lithium-polymer batteries can hold more energy per unit volume than lithium-ion batteries. This makes it possible to have smaller batteries with larger capacities, an important factor in smartphone manufacturing.
  2. Lithium polymer batteries are also easier to shape than lithium ion batteries. This makes it possible to manufacture batteries of any shape without affecting the performance of the battery in the device
  3. The internal resistance of the lithium polymer battery is also small. This makes it possible to charge these batteries quickly without significantly increasing the battery’s internal temperature. The battery can also be used for many tasks without overheating because it has a higher maximum discharge current.
  4. The self-aging rate is lower than that of lithium-ion batteries. If you store unused Li-Ion and Li-Polymer batteries, Li-Polymer batteries will have a higher battery capacity than Li-Ion batteries when checked after a few years. This aspect is important for people who don’t use the device a lot. So they can last a few years before needing to replace the battery.
  5. They are also less susceptible to heat. Compared to Li-polymer batteries, Li-ion batteries tend to lose a lot of capacity when exposed to high temperatures. This makes Li-polymer batteries safer to use even in high-temperature environments, without worrying about battery life and possible explosions in the battery itself.
  6. The only challenge with Li-polymer batteries is their price. Because the technology of Li-polymer batteries is still very new, the cost of designing and manufacturing these batteries is still higher than that of Li-ion batteries. That’s why most smartphones still use lithium-ion batteries.

Will my phone catch fire?
The answer to this question is yes. The main cause of fire is usually a short circuit within the battery system. When Samsung investigated the cause of the battery fire, they discovered that it all started when the battery’s anode and cathode began to curl. This causes the separator between the two electrodes to weaken, resulting in a short circuit. The heat that damages the two electrodes is due to the limited space between the heat-sealed protective bag around the battery and its interior. This means there is limited space to dissipate heat from the battery to the case and then to the outside of the phone.

In that case, the problem was designing the battery system. But in some cases, the phone can catch fire because the separator of an old battery has weakened over time. This can cause a short circuit and cause a fire. Another problem can be physical damage to the battery, which can lead to electrode or separator damage, which can also lead to short circuits and fires.
