Medical devices including implantable, wearable, surgical tools, and hospital equipment are increasingly being powered by battery cells and packs. Innovations in primary and secondary battery technology have enabled advances in medical device technology. This presentation will describe current applications of batteries in medical devices and examine drivers for battery technology in future medical devices.

The proliferation of connected devices has led to a need for miniaturized batteries with reliable performance. There is a limit to how much conventional designs can be downsized before they become inefficient from a process and performance perspective. Novel design approaches have been developed that can be produced by a scalable process and provide reliable seals, high volumetric efficiency, and predictable performance.

The first major lithium-ion battery technology application was portable electronics. In today’s world lithium-ion has found its way into the vehicle and stationary power markets. This new market demand influences the quality of supplies available to the consumer market. This presentation is focused on lifelong quality and will discuss some general trends. The implications in the marketplace of these trends and the need for a holistic design approach in product and manufacturing. A few hypothetical situations will be used to illustrate the challenges.

Li-ion batteries are used in many industries, such as consumer electronics, electric vehicles, and internet-of-things. With the substantially increasing demand, sustainable battery technologies are desired. This talk explains several battery algorithms: adaptive charging, situational charging, context-based battery charging, etc. All algorithms extend battery longevity and require less battery replacement, thus contributing to sustainability enhancement.

Silicon has long been heralded as the next important anode material since it can theoretically store up to 10 times as much lithium as graphite. The Enovix 100% active silicon anode can store more than twice the lithium as graphite anodes used in nearly all Li-ion batteries today. Enovix will share how the company’s novel 3D cell architecture solves the four technical problems of silicon, producing a 100% active silicon anode battery designed to deliver high-energy density without compromising safety for worldwide customers.

Outdoor power equipment, such as riding lawn mowers and snowthrowers, have traditionally been powered by internal combustion engines with very limited pollution controls and high noise levels. These environmental factors coupled with legislation mandating the transition to electric-powered equipment has made this industry a prime target for electrification. This presentation outlines a path to transforming an industry that will benefit consumers, professional users, and the planet.

In this talk, I will compare nano with micro-particle electrodes, and discuss why the battery industry is unlikely to replace micro with nano-size particles. Given this, I will address the question as to whether there is a place for nanomaterials in battery design. I will show that the way forward lies in micro-particles constructed by the assembly of nanoscale building blocks and in micro-particles with engineered or natural nano-porosity. Such multiscale particles offer exciting possibilities to develop the next generation of battery electrodes that are quintessentially both micro and nano with respect to their performance attributes.

The increased power carrying capability of USB-C has enabled fast charging in many consumer products. When designing a battery into a product with fast charging capabilities, it is critical to understand the impact on battery functional parameters like cycle life, energy density, and more. Fast charging also has an influence on cost. This talk will address these tradeoffs and attempt to set reasonable battery performance expectations.

Robotic vacuums, drones, electric lawn movers, and other self-moving devices require exact remaining run-time to return to charging port. However, predicting it is complicated by highly variable load patterns. For example, vacuum robot can run on power-hungry patch of carpet on normally hardwood floor. Basic gauging methods are highly inaccurate under such conditions, forcing to leave up to 30% of capacity in reserve - cost saved by correctly modeling usage patterns.

Beginning in 2024, California will ban all new sales of fuel-powered outdoor power equipment. Similar to autos, a traditional ICE industry showcases a boom in adoption towards alternative power sources with a focus on battery life-cycle processes. OPEI is an international trade association representing more than 100 manufacturers and their suppliers of gas and electric-powered outdoor power and transport equipment with domestic shipments of nearly 40 million products each year.

While 5G changes how the world communicates, network or component failures are not an option. As data rates increase and latency decrease, critical applications are emerging that rely on the benefits of the network. Many of these applications may rely on portable or mobile devices that are powered by batteries that require failure resistant battery management systems.This presentation covers why critical applications are emerging and leveraging the benefits of 5G and discusses why reliability of a battery management system is now more critical at a printed circuit level. Number of different tests that can be performed to validate and qualify the battery management circuit board for its reliability robustness will be covered along with its benefits.
