TRANSLATING CUSTOMER REQUIREMENTS INTO PRECISE AND QUANTITATIVE TECHNICAL SOLUTIONS

KULR’s Passive Propagation Resistant (PPR) solutions have proven to stop or mitigate the impacts of thermal runaway propagation in battery packs or between batteries. KULR’s Thermal Runaway Shield (TRS) has shown to prevent cell-to-cell propagation. Our core TRS technology was chosen by NASA to safely ship and store batteries aboard the International Space Station.

A COMPREHENSIVE DESIGN METHODOLOGY

KULR’s holistic approach to creating a distinguished product first identifies design variability and then identifies key improvement opportunities. We focus on our customer’s vision and direction, we develop a clear understanding of the customer’s module, which helps tailor ideal solutions to the client’s needs. Rigorously analyzing battery pack requirements, our design methodology ensures long term value to the customer by simultaneously optimizing the product in terms of customer benefits and product life-cycle costs.

BATTERY TRANSPORTATION SOLUTIONS

KULR provides the safest and most reliable passive propagation resistant (PPR) packaging solution for lithium batteries. As proof of that, in Fall 2019 our packaging solution was utilized by NASA to safely ship (and store) laptop batteries to the International Space Station.

Lithium batteries are regulated as hazardous material during transport and the United States Department of Transportation requires lithium batteries to adhere to applicable regulatory requirements during transportation. Whether shipping a single battery, a battery-powered device or a load shipment of batteries, the safety of those handling your package along the way is of greatest importance.

In 2020, KULR’s PPR packaging solution was chosen by Americase, who works with virtually every manufacturer of consumer electronics and is the world’s most widely used return packaging provider for damaged, defective, or recalled lithium batteries.

5G COMMUNICATION & CLOUD COMPUTING

Demand for improved, cost-effective cooling solutions in the burgeoning 5G and the rapidly growing cloud computing industries is ever-increasing. KULR collaborates with some of the world’s top companies in 5G and cloud computing to develop solutions that maximize performance and safety.

KULR Technology’s proprietary carbon fiber-based suite of thermal interface materials (FTI) offers advantages that collectively are unique and of great importance to the 5G and cloud computing industries. In particular:

  • High bulk thermal conductivity
  • Low interfacial resistance at relatively low contact pressures
  • High electrical conductivity for electromagnetic shielding
  • Exceptionally lightweight and compliant (form-fitting)
  • Industrial-level reliability
  • Highly customizable and cost-effective solutions

E-MOBILITY

One of the biggest challenges facing electric vehicle manufacturers is increasing battery energy capacity while maintaining the highest levels of battery safety in the event of a thermal runaway event.

Engineers are demanding more battery capacity to expand the range and power of existing platforms while adding new, power-demanding components for advances such as 5G data networks. These double demands will strain battery limits, increasing the risk for overheating and serious failures as well as generating heat in sensitive electronics (chip) architecture.

KULR’s passive propagation resistant (PPR) battery pack solutions mitigate those challenges by reducing weight and managing heat in the battery and electronics architecture as well as preventing catastrophic thermal runaway propagation.

ENERGY STORAGE

Inherent in the rise of battery portability will be a need for battery systems to effectively meet increased power and energy density requirements. Because of their energy density, higher voltage, and negligible memory effects, lithium-ion batteries are the popular choice for a wide range of applications, especially in portable electronics. However, larger power demands and increasing cell density of lithium-ion battery packs result in higher operating temperatures, especially under peak loads. Although rare, news of exploding electronic devices due to thermal runaway in lithium-ion batteries (Li-B) is well documented and raises serious safety concerns.

Li-B cells with cobalt cathodes should never rise above 130°C (265°F). At 150°C (302°F) the cell becomes thermally unstable causing a condition that can lead to thermal runaway in which flaming gases are vented. During thermal runaway, the high heat of the failing cell can propagate to adjacent cells causing them to become thermally unstable as well. To increase safety, packs are fitted with dividers to protect the failing cell from spreading to neighboring cells.

KULR’s HYDRA TRS is a cost-effective passive thermal management system to prevent Li-B thermal runaway propagation. It offers design simplicity and eliminates the need for costly mechanical equipment and additional capacity to power them.
