Tsoos cov roj teeb lithium txom nyem poob qis hauv huab cua txias rau 1/5} ion℃, their capacity drops to 89% of nominal levels, while at -20℃, capacity losses can reach 50-70%. More critically, low-temperature charging triggers lithium dendrite formation on anode surfaces, which can puncture separators and cause micro-short circuits. Experimental data shows that after just 10 Kev Them Nqi Ceev Ncaws Hauv -20 degree, roj teeb sab hauv kev nce los ntawm 30% .

Cov kws tshawb nrhiav ntawm Dalian lub koom haum tsim ultra-tsawg-kub elecents thiab dual-kub} -three orders of magnitude higher than conventional formulations. Crucially, their proprietary anode film-forming additive creates a low-impedance SEI layer on graphite surfaces, reducing lithium-ion intercalation resistance by 60% and enabling stable drone operation at -36℃.
