How much do you know about flexible ultra-thin lithium batteries?

The development of flexible ultra-thin lithium batteries is a big step forward. In order to further increase the flexibility of lithium battery placement, battery manufacturers have begun to study the flexible lithium battery architecture, affecting a series of technological changes such as battery material processing, battery cell stacking, electrolytes, circuit boards, and battery module architecture.

The size of mobile phone screens is increasing day by day, but the thickness is shrinking. For lithium battery manufacturers, sacrificing the Z-axis height of products must maintain or increase the capacity by increasing the area, and even need to implement a flexible architecture to improve volume utilization. The thickness of the lithium battery continues to decrease, and the capacity is significantly increased.

Future wearable electronic devices such as smart watches and smart glasses will have stronger demand for ultra-thin lithium batteries due to tight system design space and lack of flexibility in the placement of lithium batteries. Although the flexible battery supply chain is not yet mature, smart watch manufacturers have begun to introduce designs that will use the strap space to configure secondary batteries, while the watch body has a built-in lithium battery to extend the life of the device.

Looking at the demand for flexible lithium batteries, battery manufacturers have developed a flexible, highly reliable battery using proprietary solid ceramic electrolytes, flexible circuit board substrates, special anode materials and RolltoRoll technology. Lithium batteries with excellent energy density and good mass production in the near future because the product uses a solid ceramic electrolyte, compared with the traditional liquid electrolyte solution, it can ensure that the lithium battery will not have the safety problem of short circuit caused by the contact between the positive and negative electrodes in the case of repeated flexing, and accelerates the wearable wearable device application.
