I came across a report about "Nonflammable Mobile Batteries" online. I would like to summarize and share some of the interesting points here. Mobile batteries are very useful when a smartphone's battery is running low outside. Most of them are Lithium-ion batteries and they become a current must-have. However, they have some issues. Especially, they are well-known for its having a flammable risk because they use flammable organic solvent. We sometimes saw the news that mobile batteries caught fire on the train and in the garbage truck. A certain company in Osaka developed Sodium-ion mobile batteries as nonflammable ones and started to sell them in mid-March. They said this is the world's first Sodium-ion mobile battery. They have different features from Lithium-ion batteries as follows, 1)High Safety. The battery is hard to overheat and can lower a risk of catching fire even if there is a heat in the battery. 2) Robust Temperature Feature. The battery works at between -35 and 50 degrees when it discharges. In the case of Lithium-ion mobile battery, the temperature is almost between 0 and 40 degrees. 3) Long lifespan. The battery has a lifespan of about 5,000 cycles. That's why it will be available for about 13 years even if it charges one time every day. Lithium-ion's is about 500 cycles. On the other hand, the main downsides are the size and the price. I want to use it as my battery charger in the future when I go outside in such scorching hot.

I want to be a teacher

Hello everyone! Last weekend, I took the TOEIC, and it was a much tougher experience than I had imagined. Over the past few weeks, I studied hard—reviewing vocabulary, practicing listening, and taking practice tests. Even so, sitting in the actual test center felt more difficult than studying at home, and the nerves added even more pressure. The listening section started smoothly, but as the pace of the questions quickened, I realized how hard it was to maintain concentration. There were moments of anxiety, but I tried my best not to lose focus. The reading section, however, was even tougher. The sheer number of questions was overwhelming, and by the time I reached the final long passage, the clock was ticking faster than I'd anticipated, making me panic. In the end, I had to rush through the last few questions, leaving me unsure if my answers were correct. Reflecting on this experience, I realized I need to improve not only my English skills but also my time management abilities. For next time, I want to practice solving problems while timing myself more often and learn to pace myself to avoid rushing at the end. Although it was tough, taking the test strengthened my desire to improve further. Next time, I want to approach it with more confidence and composure.
