Lithium polymer betri

lithium polymer betri

Libetri tsa lithium-ion le lithium polymer ke mefuta ea betri e ka nchafatsoang hape e nang le lithium e le sesebelisoa se sebetsang sa electrochemical. Li-betri tsa Li-ion ke e 'ngoe ea mefuta ea lisele tse tsebahalang haholo lefatšeng bakeng sa lisebelisoa tsa elektronike tse nkehang habonolo. Lilemong tsa morao tjena, tlhahiso e kholo ea lisele tsena e khothalelitsoe ke tlhokahalo ea likoloi tsa motlakase tsa plug-in le lisebelisoa tsa polokelo ea marang-rang.

Libetri tsa lithium-ion e bile libeteri tsa pele tse atlehileng khoebong tsa mefuta eohle, tse etsang hore li tsejoe hantle. Ba laola 'maraka oa lisebelisoa tsa elektroniki tse nkehang habobebe ka lebaka la matla a bona a phahameng, ho tjhaja ka potlako le ho hloka mohopolo. Lihlahisoa tse phahameng tsa morao-rao tsa lisebelisoa tsa matla tsa lithium-ion li etsa hore e be tse loketseng bakeng sa lisebelisoa tse kang ho sebetsa ka mapolanka, ho cheka le ho sila.

Libetri tsa lithium polymer ke libeteri tse tšesaane, tse bataletseng tse nang le lisebelisoa tsa anode le cathode tse arohaneng ka polymer electrolyte. Electrolyte ea polymer e ka eketsa matla ho betri, ea etsa hore ho be bonolo ho paka libakeng tse nyane ho feta libeteri tsa lithium-ion.

Mofuta o tloaelehileng haholo oa betri ea lithium polymer o sebelisa lithium ion anode le electrolyte ea tlhaho, e nang le electrode e mpe e entsoeng ka carbon le anode composite cathode material. Sena se tsejoa e le sele ea mantlha ea lithium polymer.

Mofuta o tloaelehileng ka ho fetisisa oa betri ea lithium-ion o sebelisa lithium metal anode, carbon black cathode le electrolyte ea tlhaho. Electrolyte ke tharollo ea motsoako oa lintho tse phelang, letsoai la lithium le polyvinylidene fluoride. Anode e ka 'na ea hahoa ka carbon kapa graphite, cathode hangata e entsoe ka manganese dioxide.

Mefuta ena ka bobeli ea libeteri e sebetsa hantle mochesong o tlase empa libeteri tsa lithium polymer li na le matla a phahameng a lebitso ho feta sele ea lithium-ion ea boholo bo lekanang. Sena se lumella ho paka tse nyane le libeteri tsa boima bo bobebe bakeng sa lisebelisoa tsa elektroniki tse nkehang habonolo tse sebelisang li-volts tse 3.3 kapa ka tlase ho moo, joalo ka li-eReader tse ngata le li-smartphone.

Matla a bitsoang "voltage" bakeng sa lisele tsa lithium-ion ke 3.6 volts, athe libeteri tsa lithium polymer li fumaneha ho tloha ho 1.5 V ho ea ho 20 V. Libetri tse thehiloeng ho lithium-ion li na le matla a matla ho feta betri ea lithium polymer ka lebaka la boholo ba bona bo bonyenyane ba anode le khokahanyo e kholo ka hare ho anode.
