During this talk, the current dynamics of the Chinese EV market, which accounts for more than 50% of the global EV market, will be updated and, in particular, discussions will be given with regard to the cathode supply chain from an active player’s perspective.

EVE Energy Co., Ltd. has developed a series of lithium-ion "bean cells", which have unique cell designs and provide options to microelectronic devices. These patented technologies will enhance true wireless stereo (TWS) headsets, capsule robotics, and implanted sensors. Detailed bean cell technology development, excellent test results, and fully automatic manufacturing processes will be presented. EVE believes that lithium-ion batteries will expand the market for many other microelectronic devices to come.

Despite the long-time and extensive research efforts, the deployment of the technology for practical applications is still hindered by the practically low-energy and limited cycle life. In this presentation, we will discuss critical scientific challenges of Li-S batteries at the materials and cell levels, and our new progress in improving cell energy and cycling life by reducing the use of liquid electrolyte from rich to lean and, ultimately, to all-solid-state batteries.

Successful tab-to-cell connections determine the manufacturability of a battery pack. A number of challenges exist, including material selection, tolerances of fit-up, speed of assembly and monitoring to ensure that a successful weld joint was achieved. Proper equipment and process development will determine the quality and throughput that can be achieved.

We present a novel fabrication technology that reduces the resistance of negative electrodes of lithium-ion batteries (LIBs). Fast charging of high energy density LIBs is limited by increased degradation brought about by lithium plating on the negative electrode. In this talk, we investigate how reduced negative electrode resistance leads to shorter charging time without compromising energy density, safety, and lifetime.

Lithium-ion batteries are at the center of the conversion to sustainable electric transportation systems. But, the manufacturing of battery materials is energy-intensive and can have significant negative environmental impacts. Changing the energy sources and manufacturing process for production of anode materials can reduce the environmental impact of batteries. This presentation explores how anode materials with state-of the-art performance can be manufactured in a sustainable way.

In this presentation, we will discuss Thermo Fisher Scientific’s analytical solutions for battery R&D and manufacturing. Topics include: technical cleanliness study of battery materials via automatic SEM/EDX; 2D/3D imaging analysis of battery via electron microscopes; microCT; data visualization and analysis software; and thickness gauging measurement for electrode manufacturing consistency.

Electrodes are limited in their electrochemical stability and electrical performance by polymer binders.  Nanoramic has developed an alternate solution - Neocarbonix - an electrode platform technology that effectively replaces polymer binders and primers.  Results have been demonstrated for both LIB cathodes and EDLC electrodes. Nanoramic's Neocarbonix electrodes have significantly lower ESR, better C-rate capabilities, longer lifetime at high temperature, and greater active material thickness for improved energy density, while also retaining or improving specific capacity.
