Patent Trends: Batteries for electric vehicles
Analyst Insight | July 13, 2021
Rapidly growing demand for the development of batteries with high capacity, lower costs, and a longer cycle life has led researchers to not only improve today's Li‑ion batteries but also look toward future alternatives to today's Li‑ion chemistries. As the manufacturing scale of Li‑ion batteries ... Not part of subscription

Technology | October 04, 2021
Advanced anodes for Li‑ion batteries offering 10 times higher theoretical capacity than incumbent graphite, although significant technical barriers have prevented technology developers from accessing this potential for mass‑produced cells. Not part of subscription
Theion's boldly claims to send lithium sulfur batteries to space in 2022 — too soon or too good?
News Commentary | April 07, 2022
The German startup Theion has announced it will start shippping its new Li‑S battery that will exhibit a cycle life of 1,000 cycles to aerospace companies. The proposed battery chemistry using carbon nanotubes should help improve conductivity, but the biggest roadblock to their stability — ... Not part of subscription

QuantumScape showed data from single-layer pouch cells that indicated fast charging (15 minutes to 80% SoC) and 800 cycles at a 1C charge/discharge rate, which represent some of the better lab-scale results Lux has seen for a lithium anode cell. However, after more than a decade and $300 million to develop the battery, the company has failed to show a cell ready for commercialization, as it did not discuss its inability to make multilayer pouch cells and has yet to provide any validation of manufacturing costs. Lux remains firmly unconvinced that QuantumScape will meet its 2025 timeline for commercialization, as it is still only sharing lab-scale results and needs to focus on manufacturing to justify its lofty valuation.
