Nano-germanium nwere uru nke oghere dị warara dị warara, ọnụọgụ nnabata dị elu, yana nnukwu ngagharị. Mgbe etinyere ya na oyi akwa nke mkpụrụ ndụ anyanwụ, ọ nwere ike ịgbasa nnabata nke ụdịdị dị iche iche nke infrared nke sel anyanwụ.
Germanium abụrụla ihe elektrọd na-adịghị mma na-ekwe nkwa maka batrị lithium-ion n'ihi ikike echiche ya dị elu.
Theoretical uka ikike nke germanium bụ 1600 mAh / g, na olu ike dị elu dị ka 8500 mAh / cm3. Ọnụ ọgụgụ mgbasa ozi nke Li + na ihe Ge dị ihe dị ka ugboro 400 nke Si, na eletrọnịkị conductivity bụ ugboro 104 nke Si, ya mere germanium dabara adaba maka ngwaọrụ dị elu na nke dị elu.
Otu ọmụmụ kwadebere ihe mejupụtara nano-germanium-tin/carbon. Ihe carbon nwere ike imeziwanye conductivity nke germanium ka ọ na-eme mgbanwe maka mgbanwe olu ya. Mgbakwunye tin nwere ike imeziwanye conductivity nke ihe. Na mgbakwunye, akụkụ abụọ nke germanium na tin nwere ikike dị iche iche maka mmịpụta / ntinye lithium. Akụkụ nke na-adịghị etinye aka na mmeghachi omume ahụ nwere ike iji mee ihe dị ka matrix iji chekwaa mgbanwe olu nke ihe ọzọ n'oge usoro ụgwọ na mwepụ, si otú ahụ na-eme ka nkwụsi ike nhazi nke electrode na-adịghị mma.
