Customer ServiceAs a natural salt that appears on the periodic table of the elements, lithium could never be patented as a drug. It would never be a money-maker for the drug companies. Still today, some argue (with good reason) that lithium is underprescribed in the U.S. in favor of the newer, more profitable mood stabilizers and neuroleptics.
To address this issue of low efficiency for battery screening, scanned X-ray Computed Tomography (CT) cross-sectional images in combination with a computational image recognition algorithm have been employed to explore the gradient screening of these retired batteries.
Unique capability: supramolecular ionic liquid / polymer / lithium salt electrolytes with very favorable ion conductivity (up to 2.4 × 10 -3 S/cm) and high boiling point (>438 °C), along with corresponding cells with lithium metal negative electrodes. Leap of faith: the toxicity of triphenylene-containing electrolytes will be acceptable.
Comprehension of solid-state / semi-solid Li-ion battery technology decision trees allows for the identification of promising product development directions that have not yet been explored.
Although Li metal processing patents have been filed by CATL, employment of an ‘anode-free’ cell design is also a possibility. Positive electrode: NMC9½½ or NMC811 / conductive carbon / PVDF (96 : 2 : 2 by mass), see ‘Lithium-ion Battery High-energy Cathode Innovation & Patent Review’. Design: stacked multilayer, prismatic cells.
Based on the Structural Similarity Index Measure (SSIM) algorithm with 2000 CT images per battery, the calculated CT scores are closely correlated with their internal resistance and capacity, indicating the feasibility of CT scores to sort retired batteries.
