I ka makahiki 2007, ua hoʻolaha ʻia ka "New Energy Vehicle Production Access Management Rules" e hāʻawi i ke alakaʻi kulekele ʻoihana ʻenehana hou o Kina.I ka makahiki 2012, ua waiho ʻia ka "Energy-saving and New Energy Automobile Industry Development Plan (2012-2020)" a lilo i hoʻomaka o ka hoʻomohala ʻana i nā kaʻa kaʻa hou o Kina.I ka makahiki 2015, ua hoʻokuʻu ʻia ka "Notice on Financial Support Policies for the Promotional and Application of New Energy Vehicles in 2016-2020", ka mea i wehe i ka prelude i ka hoʻomohala pahū ʻana o nā kaʻa ikehu hou o Kina.
ʻO ka hoʻokuʻu ʻana o ka "Guiding Opinions on Promoting the Development of Energy Storage Technology and Industry" ma 2017 i hōʻailona i ka pahū ʻana o ka ʻoihana mālama ikehu a ua hoʻomaka ʻo 2018 i ka hoʻomaka ʻana o ka hoʻomohala wikiwiki ʻana o ka ʻoihana mālama ikehu o Kina.E like me ka mea i hōʻike ʻia ma ka Figure 1, e like me nā helu o ka Hui Kina o nā mea hana kaʻa, ʻo ka hana ʻana a me ke kūʻai ʻana o nā kaʻa ikehu hou o Kina ua hōʻike i ka ulu pahū mai 2012 a 2018;e like me ka "Energy Storage Industry Research White Paper 2019" i hoʻopuka ʻia e ka Zhongguancun Energy Storage Industry Technology Alliance E hōʻike ana ua hoʻonui nui ʻia ka hiki ke hoʻokomo ʻia o ka mālama ʻana i ka ikehu electro chemical o Kina.I ka makahiki 2017, ua helu ʻia ka nui o ka nui o ka hiki ke hoʻokomo ʻia o ka mālama ʻana i ka ikehu pākahi lithium-ion ma Kina no 58% o ka hiki ke hoʻokomo ʻia o ka mālama ʻana i ka ikehu kemika electro.
Lithium-Ion batteries i maopopo pono i loko o ke kula o ka electrochemical waihona ikehu i loko o Kina, a e holo electrochemical ikehu waihona mana o ka maikaʻi a me ka oi stably, ia mea pono e kālailai i ka hoʻopaʻi 'ana a me nā huahana pili mai kaʻaoʻao oaoieei.E like me ka mea i hōʻike ʻia ma ka Figure 2, ʻo ia ka ʻōnaehana ʻenehana o nā huahana mālama ikehu electrochemical.ʻO nā huahana ʻenehana pili i ka electrochemical (nā huahana cell, nā huahana module, nā ʻōnaehana mālama ikehu) i hōʻike ʻia e nā pā lithium-ion ka puʻuwai o ka mālama ʻana i ka ikehu electrochemical.ʻO ke kuleana o nā huahana pili ʻē aʻe e hōʻoia i ka hana ʻana o nā huahana mālama ikehu electrochemical i ʻoi aku ka maikaʻi a paʻa
No nā huahana kelepona lithium-ion, ʻo nā mea ʻenehana nui e pili ana i ka noi ʻana o ka mālama ʻana i ka ikehu electrochemical ke ola, ka palekana, ka ikehu, a me ka mana, e like me ka mea i hōʻike ʻia ma ke Kiʻi 3. ʻO ka hopena o ke ola pōʻai e pili ana i nā mea e like me ke kaiapuni hana, nā kūlana hana, ka hoʻokumu ʻana i nā mea, ka pololei kuhi, a me nā mea ʻē aʻe;a me nā hōʻailona loiloi palekana e pili ana i ka palekana uila-mana-thermal a me nā mea e pono ai ka palekana kaiapuni, e like me ke kaapuni pōkole o loko a me waho, Vibration, acupuncture, shock, overcharge, overdischarge, over temperature, high humidity, low air pressure, etc. ʻO nā kumu o ka ikaika o ka ikehu e pili nui ʻia e ka ʻōnaehana waiwai a me ke kaʻina hana.ʻO nā mea hoʻohālikelike o nā hiʻohiʻona mana e pili nui i ka paʻa o ka hoʻolālā waiwai, ka ionic conductivity a me ka uila uila, a me ka mahana hana.No laila, mai ka manaʻo hoʻolālā o nā huahana pākaukau lithium-ion, pono e uku ʻia i ke koho ʻana i nā mea, ka hoʻolālā ʻana o nā ʻōnaehana electrochemical (pono a maikaʻi ʻole, N / P ratio, compaction density, etc.), a nā kaʻina hana hana (ka hoʻomalu ʻana i ka mahana Humidity, ke kaʻina hana uhi, ke kaʻina hana wai, ke kaʻina hoʻololi kemika, etc.).
No nā huahana pākaukau lithium-ion, ʻo nā mea ʻenehana nui e pili ana i ka hoʻohana ʻana i ka mālama ʻana i ka ikehu electrochemical, ʻo ia ke kūpaʻa, ka palekana, ka mana, a me ka ikehu o ka pākaukau, e like me ka hōʻike ʻana ma ka Figure 4. ʻO ka huahana modula e pili nui ana i ka mana o ka hana hana, nā koi ʻenehana o ka hui pū ʻana o ke kelepona, a me ka pololei o ka manaʻo.ʻO ka palekana o nā huahana module e kūlike me nā koi palekana o nā huahana cell battery, akā pono e noʻonoʻo ʻia nā mea hoʻolālā e like me ka hōʻiliʻili ʻana o ka wela a me ka wela.ʻO ka nui o ka ikehu o nā huahana module e hoʻonui i kona ikehu mai ka hiʻohiʻona o ka hoʻolālā māmā, ʻoiai ʻo kona mau hiʻohiʻona mana e noʻonoʻo nui ʻia mai nā hiʻohiʻona o ka hoʻokele wela, nā hiʻohiʻona cell, a me ka hoʻolālā series-parallel.No laila, mai ka manaʻo o ka hoʻolālā ʻana o nā huahana pākaukau lithium-ion, pono e uku ʻia i nā koi o ka hoʻonohonoho ʻana, ka hoʻolālā māmā, ka hoʻolālā series-parallel, a me ka hoʻokele wela.
