Evo nešto na tragu onih "čarobnih" baterija koje će promijeniti industriju, čini se da ipak nije to baš tako jednostavno:

Objavljeno je nekoliko dodatnih testova. Pozivam sve da ovo pročitaju, jer ova baterija zbilja izgleda game changer.
Objavljen je test punjenja i pražnjenja pri visokim temperaturama (80C i 100 C). Pri tim temperaturama bi postojeće baterije NCM kemije (pa i LFP do određene mjere) već krenule nezaustavljivo u thermal getaway.
"This project included an independent high-temperature discharge performance test on an energy storage device supplied by the customer, which the customer identified as a solid-state battery cell. Based on the initial capacity test, the capacity of the cell was determined to be 24.9 Ah. The cell was discharged at +80 °C and +100 °C in accordance with the customer’s test plan, and capacity, energy and cell temperature were recorded. Under the specified conditions, the cell was successfully discharged at +80 °C using a current of 24 A, achieving a discharge capacity corresponding to 110.5 % of the initial discharge capacity at +20 °C with the same current. After the discharge, the cell was able to be charged normally, and no observable changes were detected.
The cell was also discharged at +100 °C using a current of 12 A, achieving 107.1 % of the reference discharge capacity measured at +20 °C using the same current. After the discharge, the cell was able to be charged normally; however, the cell pouch was observed to have lost its
vacuum."
Jedna od tri ćelija je izgubila vakuum (vanjska obloga je popustila), ali baterija je i dalje funkcionirala normalno. U postojećim bi baterijama iscurio elektrolit, thermal getaway i pa-pa, nezaustavljiv požar.
Test samopražnjenja
"This project included an independent self-discharge performance test on the energy storage device supplied by the customer, which the customer identified as a solid-state battery cell. Based on the initial capacity test, the capacity was determined to be 26.5 Ah at a constant current of 24 A.
After a 240-hour idle period, 97.7 % of the charged capacity was able to be discharged from the cell. The testing caused no visible damage or changes to the cell."
Ovo je sasvim u redu i sukladno postojećim baterijama.
Potom imamo objavljen video njihovog motocikla (ovo nije test VTT Technical Research Centre of Finland) gdje se baterija (kompletna baterija, ne pojedinačne ćelije, kapacitet 18 kWh) puni uz 5C intenzitet što trenutno ne podnosi niti jedna od postojećih baterija u vozilima.
Za kraj, imamo i test one oštećene ćelije da se ustanovi njezina sigurnost u tako oštećenom stanju.
"This project included independent cycling testing of an energy storage device supplied by the customer, which the customer identified as a solid-state battery cell. The test was conducted for cell DL2 that had lost its vacuum during a previous high-temperature test conducted at 100 °C. The cell was subjected to a 5C cycling test consisting of 50 cycles between 0–90 % state of charge (SOC), using the maximum voltage range specified for the cell (2.7–4.3 V). A reference performance test consisting of five cycles at 1C using the recommended voltage range (2.7–
4.15 V) was conducted before and after the 5C cycling test. The initial reference performance test yielded an average 1C discharge capacity of 24.689 Ah, based on five consecutive 1C cycles. After six cycles at 5C, the discharge capacity began to decrease rapidly and continued to do so for approximately 15 cycles, after which the rate of capacity degradation slowed and the capacity stabilized. The average 1C discharge capacity measured during the reference performance test after 50 cycles at 5C was 11.194 Ah, corresponding to a 54.66 % reduction compared to the initial capacity. The average energy efficiency during the 1C cycles, calculated from the reference performance test data, decreased from an initial value of 89.6 % to 83.0 %. After completion of the test, the cell thickness had increased by 17 %, and the cell pouch was firm."
Sve zasad objavljeno ide u smjeru da je ovo legit prekretnica u gradnji baterija.
