[Featured Stock] Lemon Nears Commercialization of 'Dream Battery' All-Solid-State... Collaboration with Japanese Firms Boosts Battery Life 8x

Lemon's stock price has been on the rise for consecutive days. The news that the commercialization of all-solid-state batteries, known as the "dream battery" due to their low explosion risk and low cost, has become more likely appears to be influencing the stock price.

As of 9:22 a.m. on the 8th, Lemon is trading at 6,500 KRW, up 6.38% from the previous day. The stock has continued its upward trend after hitting the daily price limit the day before.

According to the nanomaterials company Lemon, Kyoto University and Shinshu University in Japan published a paper on the 2nd in the international journal in the battery field, Journal of Power Sources, evaluating the performance of batteries incorporating Lemon's nanofiber electrolyte support. The paper, shared through an academic sharing platform, had the highest number of downloads among all papers published in the all-solid-state battery field over the past two months.

Batteries operate on the principle of chemical reactions occurring as ions move between the internal anode and cathode during charging and discharging. If the amount of ions moving between the anode and cathode is excessively high, the battery can explode, and the support serves to prevent this.

Lemon created an electrolyte support by attaching PVDF (polyvinylidene fluoride) nanofibers and PET microfiber nonwoven fabric to the support and charging it with electrolyte. The research team evaluated the lifespan of solid-state batteries using a general support and Lemon's support. When using a general support and charging 60 times, the battery capacity dropped from 150mAh (milliampere-hour) to 70mAh. Using Lemon's support, the capacity dropped to 130mAh. The lifespan with Lemon's support exceeded 2,000 hours. This is about eight times longer compared to the approximately 250 hours lifespan without applying the PVDF nanofiber support. The company stated that the results showed that suppressing lithium dendrite growth enables performance improvement of polymer all-solid-state batteries.

All-solid-state batteries have both the receptor and support made of solid materials. They have low fire and explosion risks, are easy to process, and are inexpensive, which is why they have been called the "dream battery" in the electric vehicle industry. In May last year, Lemon jointly filed a patent on all-solid-state electrolyte supports with Japan's Tenma Paper and Shinshu University. They plan to convert the patent to PCT (Patent Cooperation Treaty) and priority claim applications.

Kim Kwangjin, CEO of Lemon, said, "Many companies and research institutes at home and abroad are conducting research to commercialize solid-state batteries," adding, "Since Lemon has the capability for mass production and development of high-quality supports, we will leverage these strengths to grow."
