The latest news from Musashi Energy Solutions Co.,Ltd..

Notice of joint development contract with CKD Corporation.

Musashi Seimitsu Industry Co., Ltd. (Headquarters: Toyohashi City, Aichi Prefecture, President: Hiroshi Otsuka, hereinafter Musashi) is pleased to announce that CKD Corporation (Headquarters: Komaki City, Aichi Prefecture, President: Kazunori Kajimoto) and Lithium Ion Battery We are pleased to inform you that we have signed a joint development agreement for the commercialization of the manufacture and sale of roll-to-roll lithium pre-doped equipment that realizes higher capacity, longer life, and improved safety of (LIB).

Lithium predoping technology enables efficient cell design considering the capacity balance of the positive and negative electrodes of his LIB, and is widely known to be effective in improving performance and differentiating.

This lithium pre-doping device provides an epoch-making solution for the current liquid-based LIB called advanced LIB, and greatly improves the performance of LIB, which is a key device in his Tral era.

Specifically, Musashi Energy Solutions Co., Ltd. (Headquarters: Hokuto City, Yamanashi Prefecture, President: Koji Takahashi) has unique pre-doping technology that electrochemically inserts a predetermined amount of lithium into the electrodes in the electrolyte. By integrating the electrode transfer technology possessed by CKD Co., Ltd., which has been cultivated in the field of winders, we will realize the introduction of pre-doping technology into the LIB manufacturing process, which has been considered difficult until now.

The introduction of pre-doping technology makes it possible to reduce the amount of rare metals used as the positive electrode material of LIB, and by suppressing the deterioration reaction on the negative electrode side, the cycle life of his LIB is extended.

Also, according to his design, lithium predoping into the LIB can improve the energy density by about 20% to 40% and also allow him to extend the cycle life of his LIB by about 3-4 times. increase.

Musashi will continue to innovate further, provide optimal solutions for increasing the added value of power storage devices such as LIB, and contribute to the realization of a sustainable society.
